Further areas of applicability will become apparent from the description provided herein. The description and specific examples in this summary are intended for purposes of illustration only and are not intended to limit the scope of the present disclosure.
Example embodiments will be described in more detail with regard to the figures, wherein like reference numerals refer to like parts throughout the various figures unless otherwise specified, and wherein:
It should be noted that these figures are intended to illustrate the general characteristics of methods and/or structure utilized in certain example embodiments and to supplement the written description provided below. These drawings are not, however, to scale and may not precisely reflect the precise structural or performance characteristics of any given embodiment, and should not be interpreted as defining or limiting the range of values or properties encompassed by example embodiments.
One or more example embodiments will be described in detail with reference to the accompanying drawings. Example embodiments, however, may be embodied in various different forms, and should not be construed as being limited to only the illustrated embodiments. Rather, the illustrated embodiments are provided as examples so that this disclosure will be thorough and complete, and will fully convey the concepts of this disclosure to those skilled in the art. Accordingly, known processes, elements, and techniques, may not be described with respect to some example embodiments. Unless otherwise noted, like reference characters denote like elements throughout the attached drawings and written description, and thus descriptions will not be repeated.
Although the terms “first,” “second,” “third,” etc., may be used herein to describe various elements, components, regions, layers, and/or sections, these elements, components, regions, layers, and/or sections, should not be limited by these terms. These terms are only used to distinguish one element, component, region, layer, or section, from another region, layer, or section. Thus, a first element, component, region, layer, or section, discussed below may be termed a second element, component, region, layer, or section, without departing from the scope of this disclosure.
Spatially relative terms, such as “beneath,” “below,” “lower,” “under,” “above,” “upper,” and the like, may be used herein for ease of description to describe one element or feature's relationship to another element(s) or feature(s) as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as “below,” “beneath,” or “under,” other elements or features would then be oriented “above” the other elements or features. Thus, the example terms “below” and “under” may encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly. In addition, when an element is referred to as being “between” two elements, the element may be the only element between the two elements, or one or more other intervening elements may be present.
As used herein, the singular forms “a,” “an,” and “the,” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms “comprises” and/or “comprising,” when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups, thereof. As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed products. Expressions such as “at least one of,” when preceding a list of elements, modify the entire list of elements and do not modify the individual elements of the list. Also, the term “exemplary” is intended to refer to an example or illustration.
When an element is referred to as being “on,” “connected to,” “coupled to,” or “adjacent to,” another element, the element may be directly on, connected to, coupled to, or adjacent to, the other element, or one or more other intervening elements may be present. In contrast, when an element is referred to as being “directly on,” “directly connected to,” “directly coupled to,” or “immediately adjacent to,” another element there are no intervening elements present.
Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which example embodiments belong. Terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and/or this disclosure, and should not be interpreted in an idealized or overly formal sense unless expressly so defined herein.
Example embodiments may be described with reference to acts and symbolic representations of operations (e.g., in the form of flow charts, flow diagrams, data flow diagrams, structure diagrams, block diagrams, etc.) that may be implemented in conjunction with units and/or devices discussed in more detail below. Although discussed in a particular manner, a function or operation specified in a specific block may be performed differently from the flow specified in a flowchart, flow diagram, etc. For example, functions or operations illustrated as being performed serially in two consecutive blocks may actually be performed simultaneously, or in some cases be performed in reverse order.
Units and/or devices according to one or more example embodiments may be implemented using hardware and/or a combination of hardware and software. For example, hardware devices may be implemented using processing circuitry such as, but not limited to, a processor, Central Processing Unit (CPU), a controller, an arithmetic logic unit (ALU), a digital signal processor, a microcomputer, a field programmable gate array (FPGA), a System-on-Chip (SoC), a programmable logic unit, a microprocessor, or any other device capable of responding to and executing instructions in a defined manner.

The computer program and/or program code may include program or computer-readable instructions, software components, software modules, data files, data structures, and/or the like, capable of being implemented by one or more hardware devices, such as one or more of the hardware devices mentioned above. Examples of program code include both machine code produced by a compiler and higher level program code that is executed using an interpreter.
For example, when a hardware device is a computer processing device (e.g., a processor), Central Processing Unit (CPU), a controller, an arithmetic logic unit (ALU), a digital signal processor, a microcomputer, a microprocessor, etc., the computer processing device may be configured to carry out program code by performing arithmetical, logical, and input/output operations, according to the program code. Once the program code is loaded into a computer processing device, the computer processing device may be programmed to perform the program code, thereby transforming the computer processing device into a special purpose computer processing device. In a more specific example, when the program code is loaded into a processor, the processor becomes programmed to perform the program code and operations corresponding thereto, thereby transforming the processor into a special purpose processor.
Software and/or data may be embodied permanently or temporarily in any type of machine, component, physical or virtual equipment, or computer record medium or device, capable of providing instructions or data to, or being interpreted by, a hardware device. The software also may be distributed over network coupled computer systems so that the software is stored and executed in a distributed fashion. In particular, for example, software and data may be stored by one or more computer readable record mediums, including the tangible or non-transitory computer-readable record media discussed herein.
According to one or more example embodiments, computer processing devices may be described as including various functional units that perform various operations and/or functions to increase the clarity of the description. However, computer processing devices are not intended to be limited to these functional units. For example, in one or more example embodiments, the various operations and/or functions of the functional units may be performed by other ones of the functional units. Further, the computer processing devices may perform the operations and/or functions of the various functional units without sub-dividing the operations and/or functions of the computer processing units into these various functional units.

The one or more storage devices may be tangible or non-transitory computer-readable record media, such as random access memory (RAM), read only memory (ROM), a permanent mass storage device (such as a disk drive, solid state (e.g., NAND flash) device, and/or any other like data storage mechanism capable of storing and recording data. The one or more storage devices may be configured to store computer programs, program code, instructions, or some combination thereof, for one or more operating systems and/or for implementing the example embodiments described herein. The computer programs, program code, instructions, or some combination thereof, may also be loaded from a separate computer readable record medium into the one or more storage devices and/or one or more computer processing devices using a drive mechanism. Such separate computer readable record medium may include a Universal Serial Bus (USB) flash drive, a memory stick, a Blue-ray/DVD/CD-ROM drive, a memory card, and/or other like computer readable record media. The computer programs, program code, instructions, or some combination thereof, may be loaded into the one or more storage devices and/or the one or more computer processing devices from a remote data storage device via a network interface, rather than via a local computer readable record medium. Additionally, the computer programs, program code, instructions, or some combination thereof, may be loaded into the one or more storage devices and/or the one or more processors from a remote computing system that is configured to transfer and/or distribute the computer programs, program code, instructions, or some combination thereof, over a network. The remote computing system may transfer and/or distribute the computer programs, program code, instructions, or some combination thereof, via a wired interface, an air interface, and/or any other like medium.

A hardware device, such as a computer processing device, may run an operating system (OS) and one or more software applications that run on the OS. The computer processing device also may access, store, manipulate, process, and create data in response to execution of the software. For simplicity, one or more example embodiments may be exemplified as one computer processing device; however, one skilled in the art will appreciate that a hardware device may include multiple processing elements and multiple types of processing elements. For example, a hardware device may include multiple processors or a processor and a controller. In addition, other processing configurations are possible, such as parallel processors.
Although described with reference to specific examples and drawings, modifications, additions and substitutions of example embodiments may be variously made according to the description by those of ordinary skill in the art. For example, the described techniques may be performed in an order different with that of the methods described, and/or components such as the described system, architecture, devices, circuit, and the like, may be connected or combined to be different from the above-described methods, or results may be appropriately achieved by other components or equivalents.
Hereinafter, some example embodiments will be described with reference to the accompanying drawings.

Referring to
The processor 212, 222 may be configured to process computer-readable instructions of a computer program by performing basic arithmetic operations, logic operations, and I/O operations. The computer-readable instructions may be provided from the memory 211, 221 or the communication circuitry 213, 223 to the processor 212, 222. For example, the processor 212, 222 may be configured to execute received instructions in response to the program code stored in the storage device, such as the memory 211, 221.
The communication circuitry 213, 223 may provide a function for communication between the electronic device 110 and the server 150 over the network 170, and may provide a function for communication with another electronic device, for example, the electronic device 120 or another server, for example, the server 160. For example, the processor 212 of the electronic device 110 may transfer a request created based on a program code stored in a storage device (e.g., the memory 211) to the server 150 over the network 170 under control of the communication circuitry 213. Conversely, a control signal, an instruction, content, a file, etc., provided under control of the processor 222 of the server 150 may be received at the electronic device 110 through the communication circuitry 213 of the electronic device 110 by going through the communication circuitry 223 and the network 170. For example, a control signal, an instruction, content, a file, etc., of the server 150 received through the communication circuitry 213 may be transferred to the processor 212 or the memory 211, and content, a file, etc., may be stored in a record medium further includable in the electronic device 110.

The I/O interface 224 of the server 150 may be a device for interface with an apparatus (not shown) for input or output that may be connected to the server 150 or included in the server 150. For example, when processing instructions of the computer program loaded to the memory 211, the processor 212 of the electronic device 110 may display a service screen configured using data provided from the server 150 or the electronic device 120, or may display content on a display through the I/O interface 214.
According to other example embodiments, the electronic device 110 and the server 150 may include the number of components greater or less than the number of components shown in
Hereinafter, some example embodiments of methods and systems for searching for a non-context using a text in chat contents are described.
The application according to the example embodiments includes a search function of providing, as a search result, a chat message including a keyword in chat contents shared through the application in response to the keyword input from a user. The application may include a social media application that provides a social networking service, for example, a messenger and a timeline.
Although some example embodiments are described using the messenger as an example, it is provided as an example only. Features associated with example embodiments may apply various types of social media applications in addition to the messenger.
The messenger includes a search function of retrieving a chat message using a keyword input as a text. An existing search function uses a chat message including texts as a search target, however, excludes multimedia content, for example, a video and an image, from the search target.
To retrieve multimedia content, a user needs to directly scan chat contents or a content list.
For example, it is assumed that the user performs a process of retrieving an image E.
Referring to
To retrieve the image E 310, the user needs to scan the entire chat contents of the chatroom A 300 and a relatively long search time is used accordingly. Unless the user remembers the chatroom A 300, a relatively large amount of time and great effort may be used for the user to retrieve the image E 310.
The messenger may include a function, for example, a content collection function and a content archive function, of providing a content list shared through a corresponding chatroom for each chatroom. Referring to
If a number of images shared in the chatroom A 300 increases, a search time may increase. Likewise, unless the user remembers the chatroom A 300, a relatively large amount of time and great effort may be needed for the user to retrieve the image E 310.
The example embodiments relate to enhancing an existing search function and retrieving multimedia content using a word included in a text-based chat message as a keyword.
The multimedia content used herein inclusively indicates any type of contents shared through the application, for example, image, video, emoticon, emoji, link, file, vote, or notification, other than a text-type chat message.
Example embodiments may provide a search function of including, as a search target, multimedia content shared on a messenger.
A content search system implemented as a computer may be configured in the electronic device 110. For example, the content search system may be configured in a form of an independently operating program or in an in-app form of a specific application to be operable on the specific application. Depending on example embodiments, the content search system may provide a function of retrieving multimedia content from chat contents of a messenger through interaction with the server 150.
The content search system configured in the electronic device 110 may perform a content search method in response to an instruction provided from an application installed on the electronic device 110. To perform the content search method of
The processor 212 and the components of the processor 212 may control the electronic device 110 to perform operations S610 to S630 included in the content search method of
Here, the components of the processor 212 may be representations of different functions of the processor 212 that are performed by the processor 212 in response to an instruction provided from a program code stored in the electronic device 110, for example, an instruction provided from the application executed on the electronic device 110. For example, the message retriever 510 may be used as a functional representation of the processor 212 that controls the electronic device 110 to search for a chat message.
The processor 212 may read an instruction from the memory 211 to which instructions associated with control of the electronic device 110 are loaded. In this case, the read instruction may include an instruction to control the processor 212 to perform operations S610 to S630.
Referring to
In operation S620, the content extractor 520 may extract non-text content from the chat contents of the messenger based on the chat message (hereinafter, a reference message) retrieved in operation S610. Here, the chat message is a chat message including a text input as the keyword. The content extractor 520 may specify at least a portion of a chat section based on the reference message and may extract multimedia content present in the specified chat section. The content extractor 520 may extract the multimedia content in a chat section corresponding to at least one of previous and subsequent chats based on the reference message. For example, the content extractor 520 may extract a desired number of chats from among chats exchanged before and/or after a point in time at which the reference message is received and may extract multimedia content from a chat section corresponding to the extracted number of chats. For example, the content extractor 520 may extract ten previous chats and ten subsequent chats based on the reference message and may extract multimedia content present in the extracted 20 chats. As another example, the content extractor 520 may extract chats exchanged during at least one of previous and subsequent unit times based on time information of the reference message and may extract multimedia content from a chat section corresponding to the chats. For example, when the reference message is received at 9:00 am, the content extractor 520 may extract chats exchanged during 2 minutes between 1 minute before and 1 minute after 9:00 am, and may extract multimedia content present in the extracted chats. As another example, the content extractor 520 may specify a chat section from which multimedia content is to be extracted by combining a number of chats and a unit time. For example, when the number of chats exchanged during at least one unit time of previous and subsequent unit times based on time information of the reference message exceeds a threshold, the content extractor 520 may extract only a desired number of chats or may reduce a unit time in which a chat is extracted. On the contrary, when the number of chats exchanged during at least one unit time of previous and subsequent unit times based on the time information of the reference message is less than the threshold, the content extractor 520 may increase the number of chats to be extracted or may increase a unit time.
The chat section for extracting multimedia content is specified based on the reference message. Here, a criterion, for example, a previous chat/subsequent chat, a number of chats, and time, used to specify the chat section may be set by a messenger user or may be set as a predetermined (or, alternatively, desired) default value.
In operation S630, the search result provider 530 may provide a search result that includes the chat message (i.e., the reference message) including the keyword and the multimedia that is extracted from the partial chat section based on the reference message, in response to the keyword. The search result provider 530 may provide the search result, for example, the reference message corresponding to the keyword, a list of multimedia contents, and corresponding transmission and reception time information. Here, the search result provider 530 may classify and thereby provide the reference message and the multimedia content included in the search result, and may classify and thereby provide the multimedia content for each content type (e.g., image, video, emoticon, emoji, link, file, vote, and/or notification). The search result provider 530 may provide the reference message and the multimedia content included in the search result, in a preview form. For example, when the multimedia content is an image or a video, the content result provider 530 may provide a preview by applying a thumbnail to the search result. In the preview form, the content result provider 530 may provide a corresponding image for an emoticon or an emoji, may provide an uniform resource locator (URL) address or corresponding webpage information for a link, may provide a file name for a file, and may provide a title for vote or notification.
Referring to
At least a partial text of a chat message may be displayed on the cat message list 710. Here, “Younghee's B&B” included in the chat message may be displayed in highlight.
The multimedia content list 720 may be classified and thereby sorted for each content type (e.g., image, video, emoticon, emoji, link, file, vote, and/or notification).
Multimedia content may be displayed in a preview form in the multimedia content list 720. For example, in the case of an image or a video, a preview may be provided using a thumbnail 701. In the case of a link, a preview may be provided using a URL address 702. Also, in the case of a file, a preview may be provided using a file name 703.
As another example, referring to
Referring to
When displaying the chatroom A 900 on a screen of the electronic device 110, the chatroom A 900 may be displayed at a location at which a reference message 901 that is a chat message including a keyword “Younghee's B&B” is present through an automatic scroll. Although a search result item included in the multimedia content list 720 is selected, the chatroom A 900 may be displayed on the screen through a scroll to the reference message 901 from which multimedia content of the selected search result item is extracted. As another example, when a search result item included in the multimedia content list 720 is selected, and in in this instance, a plurality of multimedia contents are included in the selected search result item, the chatroom A 900 may be displayed through a scroll to content corresponding to an earliest exchange time.
A process in which the user retrieves an image E 910 is assumed in
When the user remembers that a conversation at a time of sharing the image E 910 is related to “Younghee's B&B”, the user enters “Younghee's B&B” as a keyword through a search function. In response thereto, the search result provider 530 may provide a search result including the chat message list 710 and the multimedia content list 720 corresponding to the keyword “Younghee's B&B”. The user may select a search result item through a preview provided as the search result and may enter the chatroom A 900 in which the image E 910 is shared.
As another example, referring to
Although it is described that the user is directed to a chatroom in which multimedia content is shared in response to a user selection on the multimedia content included in a search result, it is provided as an example only. The user may directly open the selected multimedia content on the electronic device 110.
Accordingly, a search function of a messenger according to example embodiments enables a user to retrieve not only text-based chat messages exchanged through a messenger and any of non-text contents.
According to example embodiments, it is possible to search for non-text content using a text in chat contents exchanged through a messenger. That is, a user may search for content being shared through an application by conducting a text search instead of directly scanning chat contents or a content list.
The systems and or apparatuses described herein may be implemented using hardware, and/or a combination of hardware and software. For example, a processing device may be implemented using one or more general-purpose or special purpose computers, such as, for example, a processor, a controller and an arithmetic logic unit, a digital signal processor, a microcomputer, a field programmable array, a programmable logic unit, a microprocessor or any other device capable of responding to and executing instructions in a defined manner. The processing device may run an operating system (OS) and one or more software applications that run on the OS. The processing device also may access, store, manipulate, process, and create data in response to execution of the software. For purpose of simplicity, the description of a processing device is used as singular; however, one skilled in the art will appreciated that a processing device may include multiple processing elements and multiple types of processing elements. For example, a processing device may include multiple processors or a processor and a controller. In addition, different processing configurations are possible, such as parallel processors.
The software may include a computer program, a piece of code, an instruction, or some combination thereof, for independently or collectively instructing or configuring the processing device to operate as desired.
