The present invention relates generally to a method, system, and computer program product for providing multimedia content. More particularly, the present invention relates to a method, system, and computer program product for automatically providing alternative points of view for multimedia content.
The consumption of media such as social media continues to increase at an accelerating rate. Users often wish to engage with media on topics that contain a fair and balanced treatment of a subject, or that, at least, present differing points of view (perspectives) on a subject. For example, a user may wish to be pointed to content (e.g., essays) that give various “sides” of an issue rather than a single perspective, for example a conservative viewpoint versus a liberal viewpoint on a particular subject. Social media sites visited by users often attempt to provide media consistent with particular perceived ideologies and interests. As a result, ideological and interest-based “echo chambers” have been created for users in which a particular user encounters only beliefs or opinions that coincide with the user's own, so that the user's existing views are reinforced, and alternative ideas are not considered. These echo chambers extend beyond politics to science, social science, and also the arts. However, many users would like to escape their echo-chambers and receive a more balanced set of perspectives on different issues and subject matters.
The illustrative embodiments provide a method, system, and computer program product. An embodiment of a method includes receiving a selection of content from a content presentation. The embodiment further includes extracting, using natural language processing (NLP), at least one topic from the selected content. In the embodiment, the at least one topic is representative of a subject conveyed within the selected content. The embodiment further includes extracting, using NLP, at least one perspective associated with the at least one topic. In the embodiment, the at least one perspective is representative of a point of view conveyed within the selected content regarding the at least one topic. The embodiment further includes determining a topic rating of the extracted topics and associated perspectives based upon the extracted topics and associated perspectives. In the embodiment, the topic rating is representative of a topic diversity among the extracted topics and associated perspectives. The embodiment further includes presenting the topic rating within a graphical user interface (GUI).
Another embodiment further includes searching a content source for complementary content based upon the topic rating to determine one or more complementary content search results for the extracted topics and perspectives, and receiving a selection from among the one or more complementary content search results. Another embodiment further includes presenting the one or more complementary content search results in the GUI, and receiving the selection from among the one or more complementary content search results using the GUI.
Another embodiment further includes retrieving complementary content associated with the selected complementary content search results, and providing the complementary content within the GUI. In another embodiment, the complementary content is presented within the GUI as part of a Web browser plugin. In another embodiment, the complementary content is presented within a pop up window in the GUI. In another embodiment, the complementary content is presented within the GUI as part of an electronic book. In another embodiment, the complementary content is presented within a broadcast. In another embodiment, the complementary content is presented as closed caption information within the broadcast.
In another embodiment, extracting the at least one topic includes representing the at least one topic as a vector in a vector space. In another embodiment, the extracting of the at least one topic includes using one or more of probabilistic latent semantic indexing (PLSI), Latent Dirichlet allocation (LDA), Pachinko allocation, singular value decomposition (SVD), the method of moments, and non-negative matrix factorization (NMF).
In another embodiment, the topic rating is representative of one of an orthogonality, an opposition, and an independence among the extracted topics and associated perspectives. In another embodiment, the GUI is configured to allow a user to select the content from the content presentation. In another embodiment, the extracting of the topic is performed at one or more of a sentence level of content organization and a document level of content organization.
In another embodiment, the GUI includes an electronic calendar application having at least one calendar entry, the GUI allowing selection of the at least one calendar entry, and wherein the complementary content includes at least one of an alternative point of view of a meeting topic associated with the calendar entry, a link to one or more other calendar entries providing a complementary viewpoint. In another embodiment, the other calendar entries are sorted in order of degree of complementarity.
An embodiment includes a computer usable program product. The computer usable program product includes one or more computer-readable storage devices, and program instructions stored on at least one of the one or more storage devices.
An embodiment includes a computer system. The computer system includes one or more processors, one or more computer-readable memories, and one or more computer-readable storage devices, and program instructions stored on at least one of the one or more storage devices for execution by at least one of the one or more processors via at least one of the one or more memories.
Certain novel features believed characteristic of the invention are set forth in the appended claims. The invention itself, however, as well as a preferred mode of use, further objectives and advantages thereof, will best be understood by reference to the following detailed description of the illustrative embodiments when read in conjunction with the accompanying drawings, wherein:
The illustrative embodiments recognize that the presently available tools or solutions do not address these needs or provide adequate solutions for these needs. The illustrative embodiments used to describe the invention generally address and solve the above-described problems and other problems related to providing complementary media content including alternative points of view for selected media content.
An embodiment can be implemented as a software application. The application implementing an embodiment can be configured as a modification of an existing media content provider system, as a separate application that operates in conjunction with an existing media content provider system, a standalone application, or some combination thereof.
One or more embodiments are directed to a method and system for presenting multimedia content to a user, detecting and/or extracting topics and points of view (perspectives) in the content, and a providing a rating of topic diversity, for example “orthogonality”, independence, or opposition, determined based upon the perspectives to a user. In particular embodiments, the multimedia content may include, for example, text within a Web browser, an essay, a book, an electronic book (eBook), broadcast media such as a television program, vocal output of broadcast commentators, a news story, a blog post, a PowerPoint presentation, a magazine article, or a technical journal papers. In one or more embodiments, the rating of topic diversity is used to search for complementary content and automatically provide access to the complementary content to the user.
As background, note that “a point of view” is a specified or stated manner of consideration, an attitude regarding how one sees or thinks of something, as in “from doctor's point of view”. In this meaning, the usage of “point of view” is synonymous with one of the meanings of the term perspective. In machine learning and natural language processing (NLP), a topic model is a type of statistical model for discovering abstract “topics” that occur in a collection of documents in which a topic represents a subject or theme conveyed within content.
Users often wish to engage in topics that contain a fair and balanced treatment of a subject, or at least differing points of views (perspectives) on a subject. For example, a user may wish to be pointed to content (e.g. essays) that provide various “sides” of an issue rather than a single perspective such as solely a conservative or liberal viewpoint on a subject. Providing differing perspectives on a topic is not only useful in the field of education, but people reading or listening to news stories may also welcome this feature for automatically obtaining varied points of view about a particular topic so that a diversity of perspectives regarding a particular topic can be made available to a user.
In one or more embodiments, a perspective associated with a topic is mathematically represented as a vector in a vector space. In vector spaces, diversity can be measured by comparing vectors to each other or by deriving a statistic for an ensemble of vectors. For example, two vectors may be determined to be orthogonal (90 degrees apart) from one another or opposite (180 degrees apart) from one another with respect to a perspective represented by the individual vectors. Ensembles of vectors may be diverse and contain vectors that cover a vector space. In an ensemble of vectors, a useful measure of diversity is a particular vector's statistical independence from the ensemble. Vectors that maximize their independence from the ensemble also maximize the entropy of the ensemble. When the ensemble is a function of some other ensemble, the maximally independent vectors maximize the information about the other ensemble.
In particular embodiments, a system performs topic extraction on multimedia content using one or more of probabilistic latent semantic indexing (PLSI), Latent Dirichlet allocation (LDA), Pachinko allocation, singular value decomposition (SVD), the method of moments, algorithms based upon non-negative matrix factorization (NMF), or any other suitable algorithm or procedure for extracting topics from multimedia content.
In an embodiment, extracting a topic from multimedia content includes representing the multimedia content as a vector in a vector space. In the embodiment, a system or application system compares topic vectors to each other or to an ensemble of topic vectors. In particular embodiments, an application accesses software and/or libraries configured for topic extraction to facilitate the extraction of topics and perspectives from multimedia content.
In one or more embodiments, the application receives a selection of multimedia content from a user, extracts one or more topics and corresponding perspectives from the selected content, determines a topic rating for an extracted topic, searches one or more complementary content sources for complementary content based upon the topic rating, and presents a listing of one or more choices of complementary content (e.g., an alternate point of view) as a suggestion to a consumer (e.g., a user) of the multimedia content within a graphical user interface (GUI) of a client device. In an embodiment, the graphical user interface further includes an indication of the whether the complementary content is orthogonal, opposite, or maximally independent from a given topic or ensemble of topics. In particular embodiments, complementary content (e.g. an alternate point of view) may be suggested to a consumer of content as part of an eBook or as part a broadcast television feature.
In an embodiment, a GUI is provided to allow a user to select sections of a document (e.g. containing assertions) to provide an alternate point of view to the selected content. In a particular embodiment, colors of the GUI buttons may indicate degree of complementarity (or orthogonality) of the respective viewpoint of the complementary content. In another particular embodiment, a user selects a GUI button in a Web browser interface to find and be presented with an alternate point of view for the currently displayed content.
Various embodiments may be directed to different levels of content organization. In one example, a system or application operates at a document level in which a perspective from which a document is written or a video is produced is identified from the content. In another example, the system or application operates at a sentence level in which sentences are identified that strongly express a particular perspective in order to offer a diversity of perspectives.
In a particular usage example, the system or application may employ a machine learning model to identify thesis statements in student essays as a classification task and then present complementary viewpoints to the statements. In another particular usage example, the system or application may be used by authors of newspaper articles or students to aid in end-to-end argument mining in persuasive essays. In another particular usage example, the system or application may be used to find other social networks or bulletin boards that express complementary points of view. In another particular usage example, the system or application may be used by reviewers of content in magazines, technical journals, etc. In another particular usage example, the system or application may be used by debaters, lawmakers, policy makers, politicians, etc. to present alternative viewpoints from their competition.
In one or more embodiments, various visualization choices may be offered as indicators to the diversity of views presented in content, e.g., an article, to the user such as a particular color in text, in a table of contents, etc. In particular embodiments, a GUI may be may be used to pop up different windows and present display screens (or Web browser windows) showing complementary content. In another particular embodiment, colors of the GUI buttons may indicate degree of complementarity (or orthogonality) of viewpoint.
In another embodiment, the system or application interfaces with a calendar application to enable a GUI to provide a user with complementary content related to a meeting scheduled in the calendar application in response to a selection by the user. In a particular embodiment, the GUI includes a button associated with one or more calendar entries to allow a user to select the button to obtain alternative points of view on a meeting topic associated with the particular meeting corresponding to the calendar entry. For example, a user preparing for a meeting on the topic of the future of blockchain applications may press the button and become better prepared by being provided with complementary content for the topic including alternative points of view (e.g. links to presentations, web pages, articles, etc.). In other particular embodiments, the buttons may also be pressed after a meeting to learn more about a meeting topic of a past meeting. In particular embodiments, input to the system or application may include calendar information for a meeting, an attendee list (and job titles and organizations for which the attendees work), and any attached presentations or links to content associated with a meeting, etc. Calendar entries may include entries for meetings, announcements, presentations on topics, etc. Such GUI buttons on calendars may also provide links to other meetings (past or future) that provide similar or complementary viewpoints. Viewpoints may initially only be estimates based on sparse information, but such information may be updated as meeting information is attached or linked to a calendar entry. Moreover, such GUI buttons on calendars can be used to “show me all meetings” with complementary viewpoints sorted in order of degree of complementarity.
In a Web-based eCommerce usage example, a user may shop for particular content, such as a book or article, on an eCommerce website and be provided with a listing of articles or books with alternative or complementary viewpoints for purchase. In a particular embodiment, GUI buttons may be presented at such eCommerce websites for selecting to purchase the “orthogonal” content items for sale.
In another embodiment, a service is implemented to maintain a large multi-dimensional array of topics, and one or more GUI buttons as described above as based, in part, upon lookups into the array. By way of example, consider an article A about the Spanish exploring South America, and then declaring, “This land belongs to the Spanish Empire!” The Spanish thought the Spanish culture was superior to the indigenous culture. Using a look-up table, an “Alternative perspective” includes one or more articles B on Peru from the point of view of the Incans, describing advanced civilizations, governments, and religions, etc. In another example, candidate articles for B may have certain topics, which are determined from latent semantic indexing and the like. In the embodiment, rules are implemented in the form of: if article A has topics 1, 2, and 3, then it return articles B with topics 4, 5, and 6.
In another embodiment, author diversity is used to determine complementary media content. In particular embodiments, GUI buttons may also take into consideration the author of an article, or host of a show, etc., when known. In such a case, difference of view point might be partially estimated by authorship. For example, if a user is reading a writing by author Noam Chomsky and presses the GUI button, the user may be provided with a writing by Sam Harris on the same topic.
In another embodiment, the determination of complementary media content is performed in association with a closed captioning application. In an example application, a user is watching the evening news on a politically conservative TV channel, and alternative viewpoints are presented as closed caption information in text on the bottom of the screen.
In yet another embodiment, the GUI is used to highlight the topics within a document for which a viewpoint (e.g. conservative or liberal) can be ascertained. In an example usage, a service can be provided to assist students in interpreting an essay or text book.
In still another embodiment, topics are compared to an ensemble of given topics using procedures such as Principal Component Analysis, Singular Value Decomposition (SVD), or Independent Component Analysis (ICA).
In another embodiment, the complementary content (e.g. alternate point of view) is suggested or presented to a consumer of the content as part a Web browser plugin. In one or more embodiments, the complementary content is one of orthogonal to, opposite of, independent from the selected media content. In another embodiment, the complementary content is suggested or presented to a consumer of the selected content as part of an eBook. In still another embodiment, the complementary content is suggested or presented to a consumer of the selected content as part a broadcast (e.g., television) feature.
In another embodiment, a GUI is used to select sections of a document (e.g., sentences containing assertions) to provide an alternate point of view of the selected sections.
In various embodiments, the extracting of topics is performed at a sentence level, a document level, or any other level of content organization. In another embodiment, the system or application pops up windows showing the complementary content that is different from a window showing the selected content.
The manner of providing complementary media content for selected media content is unavailable in the presently available methods. A method of an embodiment described herein, when implemented to execute on a device or data processing system, comprises substantial advancement of the functionality of that device or data processing system in providing complementary media content for selected media content.

With reference to the figures and in particular with reference to
Clients or servers are only example roles of certain data processing systems connected to network 102 and are not intended to exclude other configurations or roles for these data processing systems. Server 104 and server 106 couple to network 102 along with storage unit 108. Software applications may execute on any computer in data processing environment 100. Clients 110, 112, and 114 are also coupled to network 102. A data processing system, such as server 104 or 106, or client 110, 112, or 114 may contain data and may have software applications or software tools executing thereon.
Only as an example, and without implying any limitation to such architecture,
Device 132 is an example of a device described herein. For example, device 132 can take the form of a smartphone, a tablet computer, a laptop computer, client 110 in a stationary or a portable form, a wearable computing device, or any other suitable device. Any software application described as executing in another data processing system in
Application 105 implements an embodiment described herein. Server 106 includes a natural language processing engine (NLP) 107 configured to process media content and perform natural language processing on the media content to extract topics and perspectives from the media content. In other embodiments, application 105 may be configured to perform the extracting of topics and perspectives from media content. Multimedia content 109, such as complementary media content, may be stored in storage 108 as shown or supplied by another source (not shown).
Servers 104 and 106, storage unit 108, and clients 110, 112, and 114, and device 132 may couple to network 102 using wired connections, wireless communication protocols, or other suitable data connectivity. Clients 110, 112, and 114 may be, for example, personal computers or network computers.
In the depicted example, server 104 may provide data, such as boot files, operating system images, and applications to clients 110, 112, and 114. Clients 110, 112, and 114 may be clients to server 104 in this example. Clients 110, 112, 114, or some combination thereof, may include their own data, boot files, operating system images, and applications. Data processing environment 100 may include additional servers, clients, and other devices that are not shown.
In the depicted example, data processing environment 100 may be the Internet. Network 102 may represent a collection of networks and gateways that use the Transmission Control Protocol/Internet Protocol (TCP/IP) and other protocols to communicate with one another. At the heart of the Internet is a backbone of data communication links between major nodes or host computers, including thousands of commercial, governmental, educational, and other computer systems that route data and messages. Of course, data processing environment 100 also may be implemented as a number of different types of networks, such as for example, an intranet, a local area network (LAN), or a wide area network (WAN).
Among other uses, data processing environment 100 may be used for implementing a client-server environment in which the illustrative embodiments may be implemented. A client-server environment enables software applications and data to be distributed across a network such that an application functions by using the interactivity between a client data processing system and a server data processing system. Data processing environment 100 may also employ a service oriented architecture where interoperable software components distributed across a network may be packaged together as coherent business applications. Data processing environment 100 may also take the form of a cloud, and employ a cloud computing model of service delivery for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g. networks, network bandwidth, servers, processing, memory, storage, applications, virtual machines, and services) that can be rapidly provisioned and released with minimal management effort or interaction with a provider of the service.
With reference to
Data processing system 200 is also representative of a data processing system or a configuration therein, such as data processing system 132 in
In the depicted example, data processing system 200 employs a hub architecture including North Bridge and memory controller hub (NB/MCH) 202 and South Bridge and input/output (I/O) controller hub (SB/ICH) 204. Processing unit 206, main memory 208, and graphics processor 210 are coupled to North Bridge and memory controller hub (NB/MCH) 202. Processing unit 206 may contain one or more processors and may be implemented using one or more heterogeneous processor systems. Processing unit 206 may be a multi-core processor. Graphics processor 210 may be coupled to NB/MCH 202 through an accelerated graphics port (AGP) in certain implementations.
In the depicted example, local area network (LAN) adapter 212 is coupled to South Bridge and I/O controller hub (SB/ICH) 204.

Hard disk drive (HDD) or solid-state drive (SSD) 226 and CD-ROM 230 are coupled to South Bridge and I/O controller hub 204 through bus 240. PCI/PCIe devices 234 may include, for example, Ethernet adapters, add-in cards, and PC cards for notebook computers. PCI uses a card bus controller, while PCIe does not. ROM 224 may be, for example, a flash binary input/output system (BIOS). Hard disk drive 226 and CD-ROM 230 may use, for example, an integrated drive electronics (IDE), serial advanced technology attachment (SATA) interface, or variants such as external-SATA (eSATA) and micro-SATA (mSATA). A super I/O (SIO) device 236 may be coupled to South Bridge and I/O controller hub (SB/ICH) 204 through bus 238.

In particular embodiments, the extraction of topics from the selected content includes transforming the topics into vector representations in a vector space. In particular embodiments, the topic extraction is performed by one or more of probabilistic latent semantic indexing (PLSI), Latent Dirichlet allocation (LDA), Pachinko allocation, singular value decomposition (SVD), the method of moments, algorithms based upon non-negative matrix factorization (NMF), or any other known algorithm or procedure for extracting topics from multimedia content.
In block 606, application 105 extracts one or more perspectives associated with each topic from the selected content. In one or more embodiments, a particular perspective is representative of a point of view conveyed within the selected content regarding the topic. In a particular embodiment, application 105 divides up sentences from the selected content containing statements of point of view or asserted fact from the content are divided up and associates the sentences, to the extent possible, with a particular topic Ti. In particular embodiments, statements that are not strongly associated with any topic determined from the content are discarded. In other particular embodiments, one or more sentences may be associated with more than one topic. For those sentences associated with at least one topic, application 105 extracts what are determined to be statements of opinion and as well as statements of asserted fact since “statements of fact” may also be a matter of disagreement such as in the political realm. In particular embodiments, detecting of assertions of fact and assertions of opinion are determined using natural language processing (NPL) such as described in U.S. Pat. No. 9,483,582. In one or more embodiments, the statements of facts and statements of opinion form one or more perspectives for the topic conveyed by the selected content.
In 608, application 105 determines a topic rating of the extracted topics and associated perspectives including a topic diversity of extracted topics such as one or more of orthogonality, opposition, and independence, based upon the extracted topics and perspectives. In 610, application 105 provides the topic rating to the user. In a particular embodiment, providing the topic rating to the user includes presenting the topic rating within a GUI.
In 612, application 105 creates a negation corresponding to each perspective representing a complementary point of view to the particular perspective. In particular embodiments, a statement of fact or opinion, and the associated negation, are really equivalence classes of statements, all of which convey to the same thing. Thus, a key component is to find the classes in each article and determine, for each class, how numerous the positive assertions are compared with the negative assertions. If there is a noticeable difference then it can be stated with some confidence that for topic Ti, the content (e.g., an article) represents the assertion of fact/opinion Aj.
The collection of all such {Aj} for the given topic is somewhat representative of the article's stance on topic Ti. A second article will take on opposing views to the extent that, for each given Ti, it represents {˜Aj} for all j where ˜Aj denotes “not Aj”.
The degree to which another article disagrees with the present article for a given topic Ti can be established based on how many of the assertions Aj from the first article show up in the form ˜Aj in the other article. This provides a simple measure of the degree to which one article disagrees with another on a given topic. If, on the other hand, one is looking for the degree of disagreement across all topics, then the disagreement score can either be averaged across topics, or a weighted average of the disagreement scores can be taken, considering the degree of importance the given topic is to the article in question.
In 614, application 105 searches one or more complementary media sources using the negations to determine search results identifying complementary media content to the selected media content. In 616, application 105 receives the search results of the complementary media sources. In 618, application 105 filters the search results based on the topic rating. In 620, application 105 provides the complementary search results to the user 620. In 622, application 105 receives a search result selection from the user selection one or more of the complementary media sources. In 624, application 105 retrieves the selected complementary media content from the complementary media content source(s). In 626, application 105 provides the complimentary media content to the user via the client device. The procedure 600 then ends.
Thus, a computer implemented method, system or apparatus, and computer program product are provided in the illustrative embodiments for providing complementary media content for selected media content and other related features, functions, or operations. Where an embodiment or a portion thereof is described with respect to a type of device, the computer implemented method, system or apparatus, the computer program product, or a portion thereof, are adapted or configured for use with a suitable and comparable manifestation of that type of device.
Where an embodiment is described as implemented in an application, the delivery of the application in a Software as a Service (SaaS) model is contemplated within the scope of the illustrative embodiments. In a SaaS model, the capability of the application implementing an embodiment is provided to a user by executing the application in a cloud infrastructure. The user can access the application using a variety of client devices through a thin client interface such as a web browser (e.g., web-based e-mail), or other light-weight client-applications. The user does not manage or control the underlying cloud infrastructure including the network, servers, operating systems, or the storage of the cloud infrastructure. In some cases, the user may not even manage or control the capabilities of the SaaS application. In some other cases, the SaaS implementation of the application may permit a possible exception of limited user-specific application configuration settings.
The present invention may be a system, a method, and/or a computer program product at any possible technical detail level of integration. The computer program product may include a computer readable storage medium (or media) having computer readable program instructions thereon for causing a processor to carry out aspects of the present invention.
The computer readable storage medium can be a tangible device that can retain and store instructions for use by an instruction execution device. The computer readable storage medium may be, for example, but is not limited to, an electronic storage device, a magnetic storage device, an optical storage device, an electromagnetic storage device, a semiconductor storage device, or any suitable combination of the foregoing. A non-exhaustive list of more specific examples of the computer readable storage medium includes the following: a portable computer diskette, a hard disk, a random access memory (RAM), a read-only memory (ROM), an erasable programmable read-only memory (EPROM or Flash memory), a static random access memory (SRAM), a portable compact disc read-only memory (CD-ROM), a digital versatile disk (DVD), a memory stick, a floppy disk, a mechanically encoded device such as punch-cards or raised structures in a groove having instructions recorded thereon, and any suitable combination of the foregoing. A computer readable storage medium, as used herein, is not to be construed as being transitory signals per se, such as radio waves or other freely propagating electromagnetic waves, electromagnetic waves propagating through a waveguide or other transmission media (e.g., light pulses passing through a fiber-optic cable), or electrical signals transmitted through a wire.
Computer readable program instructions described herein can be downloaded to respective computing/processing devices from a computer readable storage medium or to an external computer or external storage device via a network, for example, the Internet, a local area network, a wide area network and/or a wireless network. The network may comprise copper transmission cables, optical transmission fibers, wireless transmission, routers, firewalls, switches, gateway computers and/or edge servers. A network adapter card or network interface in each computing/processing device receives computer readable program instructions from the network and forwards the computer readable program instructions for storage in a computer readable storage medium within the respective computing/processing device.
Computer readable program instructions for carrying out operations of the present invention may be assembler instructions, instruction-set-architecture (ISA) instructions, machine instructions, machine dependent instructions, microcode, firmware instructions, state-setting data, configuration data for integrated circuitry, or either source code or object code written in any combination of one or more programming languages, including an object oriented programming language such as Smalltalk, C++, or the like, and procedural programming languages, such as the “C” programming language or similar programming languages. The computer readable program instructions may execute entirely on the user's computer, partly on the user's computer, as a stand-alone software package, partly on the user's computer and partly on a remote computer or entirely on the remote computer or server. In the latter scenario, the remote computer may be connected to the user's computer through any type of network, including a local area network (LAN) or a wide area network (WAN), or the connection may be made to an external computer (for example, through the Internet using an Internet Service Provider). In some embodiments, electronic circuitry including, for example, programmable logic circuitry, field-programmable gate arrays (FPGA), or programmable logic arrays (PLA) may execute the computer readable program instructions by utilizing state information of the computer readable program instructions to personalize the electronic circuitry, in order to perform aspects of the present invention.
Aspects of the present invention are described herein with reference to flowchart illustrations and/or block diagrams of methods, apparatus (systems), and computer program products according to embodiments of the invention. It will be understood that each block of the flowchart illustrations and/or block diagrams, and combinations of blocks in the flowchart illustrations and/or block diagrams, can be implemented by computer readable program instructions.
These computer readable program instructions may be provided to a processor of a general purpose computer, special purpose computer, or other programmable data processing apparatus to produce a machine, such that the instructions, which execute via the processor of the computer or other programmable data processing apparatus, create means for implementing the functions/acts specified in the flowchart and/or block diagram block or blocks. These computer readable program instructions may also be stored in a computer readable storage medium that can direct a computer, a programmable data processing apparatus, and/or other devices to function in a particular manner, such that the computer readable storage medium having instructions stored therein comprises an article of manufacture including instructions which implement aspects of the function/act specified in the flowchart and/or block diagram block or blocks.
The computer readable program instructions may also be loaded onto a computer, other programmable data processing apparatus, or other device to cause a series of operational steps to be performed on the computer, other programmable apparatus or other device to produce a computer implemented process, such that the instructions which execute on the computer, other programmable apparatus, or other device implement the functions/acts specified in the flowchart and/or block diagram block or blocks.
The flowchart and block diagrams in the Figures illustrate the architecture, functionality, and operation of possible implementations of systems, methods, and computer program products according to various embodiments of the present invention. In this regard, each block in the flowchart or block diagrams may represent a module, segment, or portion of instructions, which comprises one or more executable instructions for implementing the specified logical function(s). In some alternative implementations, the functions noted in the blocks may occur out of the order noted in the Figures. For example, two blocks shown in succession may, in fact, be executed substantially concurrently, or the blocks may sometimes be executed in the reverse order, depending upon the functionality involved. It will also be noted that each block of the block diagrams and/or flowchart illustration, and combinations of blocks in the block diagrams and/or flowchart illustration, can be implemented by special purpose hardware-based systems that perform the specified functions or acts or carry out combinations of special purpose hardware and computer instructions.
