The embodiments described herein relate generally to textual language processing. More specifically, the embodiments described herein relate to generating patterns from a corpus of text.
Cognitive computing is the simulation of human thought processes in a computerized model; cognitive computing involves self-learning systems that use data mining, pattern recognition and natural language processing to mimic the way the human brain works. Rather than being programmed to anticipate every possible answer or action needed to perform a function or set of tasks, cognitive computing systems are trained using artificial intelligence and machine learning algorithms to sense, predict, infer, and in some ways, think. As we are moving towards the cognitive computing era, it is very important for a system to understand data content scattered across diverse geographic locations.
An important type of data content with respect to cognitive computing is textual content. Many algorithms and approaches have been proposed to understand and extract entities and relationships in text, which may be referred to as entity oriented mining. Entity oriented mining has various applications. For instance, entity oriented mining can help a medical researcher diagnose a disease, identify the cause of a disease, and appropriately treat the disease. Furthermore, entity oriented mining can assist in the field of medical research with discovery of new uses for existing pharmaceuticals, and can establish connections between a gene and species.
Machine learning approaches and rule based approaches have been proposed to detect entities from text. These approaches are very hard to scale to a new domain. This is especially true if the developer has limited knowledge about the system. Often time, these approaches are time and cost consuming, as the process of developing an entity annotator must be performed manually.
The aspects described herein include a method for generating hierarchical patterns based on a corpus of text.
A computer-implemented method is provided for generating hierarchical patterns based on internal text and external context. The method includes analyzing the corpus for an annotated entity, which includes extracting a set of features of the corpus. A set of grammatical patterns are generated based on the extracted set of features. More specifically, the set of grammatical patterns includes at least one grammatical pattern generated from an internal pattern and at least one grammatical pattern generated from an external pattern. The grammatical patterns of the set are organized into a hierarchy or are ranked. The at least one performed action is visually displayed.
Other features and advantages will become apparent from the following detailed description of the presently preferred embodiment(s), taken in conjunction with the accompanying drawings.
The drawings referenced herein form a part of the specification. Features shown in the drawings are meant as illustrative of only some embodiments, and not all embodiments, unless otherwise explicitly indicated.
It will be readily understood that the components of the embodiments described herein, as generally described and illustrated in the Figures herein, may be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the method, computer program product, and system, as presented in the Figures, is not intended to limit the scope of the claims, but is merely representative of selected embodiments.
Reference throughout this specification to “a select embodiment,” “one embodiment,” or “an embodiment” means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment. Thus, appearances of the phrases “a select embodiment,” “in one embodiment,” or “in an embodiment” in various places throughout this specification are not necessarily referring to the same embodiment.
The illustrated embodiments described herein will be best understood by reference to the drawings, wherein like parts are designated by like numerals throughout. The following description is intended only by way of example, and simply illustrates certain selected embodiments of devices, systems, and processes that are consistent with the claims herein.\
Following the receipt at steps (102) and (104), the corpus of text is analyzed (106), which in one embodiment includes extracting a set of features of the corpus (108). In one embodiment, the set of features of the corpus that are extracted include an annotated entity and an associated context of the entity. The annotated entity, as known in the art, is an entity that has a corresponding characterization that is configured to be computer readable for grammatical analysis. Typically, an individual (e.g., an expert, a researcher, etc.) manually annotates a desired entity of the corpus of text. The illustrative embodiments described herein with reference to
In one embodiment, the extracted features are tokenized, which includes tokenizing the annotated entity and the associated context. As is known in the art, tokenization is the process of translating a portion of text into meaningful (e.g., machine-readable) “tokens” for processing. In one embodiment, tokenization is performed utilizing a tokenizer.
A set of grammatical patterns is generated based on the extracted features from an internal pattern and an external pattern (110). In one embodiment, the internal pattern is a pattern associated with the annotated entity, and the external pattern is a pattern associated with the associated context of the entity. In other words, the internal pattern is composed of information about the annotated entity itself, while the external pattern is composed of information about the associated context. The grammatical patterns generated from the internal pattern include an internal surface-level pattern and an internal semantic-level pattern, and the grammatical patterns generated from the external pattern include an external surface-level and one or more external semantic-level patterns. The internal semantic-level pattern is generated based on the tokenized annotated entity, and each external semantic-level pattern is generated based on the tokenized associated context. In one embodiment, the set of grammatical patterns includes one or more combination patterns. A combination pattern is a pattern that is generated from the combination of at least two generated patterns. For example, a combination pattern may be a hybrid pattern generated from the combination of two generated patterns.
Exemplary pseudocode will now be provided for performing the pattern generation process described above, in accordance with the embodiments described herein:
Further details with respect to the generation of the grammatical patterns are described below with reference to
In one embodiment, the internal and external semantic-level patterns are internal and external part-of-speech-level patterns, respectively. It is to be understood and appreciated that a part-of-speech-level pattern is just one type of semantic-level pattern. Other examples of semantic-level patterns include, but are not limited to, a person-level pattern, a location-level pattern, sentence-structure-level pattern (e.g., subject-verb-object pattern), etc. Accordingly, the embodiments described herein are not limited to part-of-speech-level patterns.
One or more grammatical patterns of the generated set of grammatical patterns (e.g., pattern set P). are evaluated (112). The evaluation of the external patterns includes performing a statistical analysis to determine a relevancy of results with respect to each generated external pattern. The statistical analysis at step (112) may employ an information retrieval process whereby a query is submitted into an information retrieval system in order to find the most relevant results. According, each generated external pattern may be considered an input query associated with an information retrieval system.
In one embodiment, the evaluation at step (112) applies one or more set-based measures to the input generated external pattern. A set-based measure is a measure that evaluates the quality of an unordered set. Set-based measures include, for example, recall, precision, and F-score. Recall is the measure of the ability of a system to present all relevant items, and is represented mathematically as a quotient of the number of relevant items retrieved and the total number of relevant items. In other words, recall may be interpreted as the probability that a relevant item is retrieved from the query. Precision is the measure of the ability of a system to present only relevant items, and is represented mathematically as the quotient of the number of relevant items retrieved and the total number of items retrieved. The F-score is derived from the recall and precision measures, and is the weighted harmonic mean of precision and recall. Generally, F-score is represented mathematically as:
(1+x̂2)(P·R)/(x̂2·P+R)
, where P represents precision, R represents recall, and x is a weight variable that may be adjusted depending on the desired precision-to-recall weight. Other types of set-based measures are known in the art, and may be utilized depending on the desired relevancy or quality analysis. Accordingly, each generated external pattern is evaluated to determine relevancy.
In one embodiment, each evaluated generated pattern is associated with evaluation data, such as evaluation metadata. From the evaluation at step (112), the external patterns may be ranked (114). In one embodiment, the external patterns are adaptively ranked. The ranking (114) may be performed manually. With reference to
Alternatively, from the evaluation at step (112), the generated patterns may be organized into a hierarchy (116). In one embodiment, the hierarchy is organized based on pattern generality. For example, a most general grammatical pattern, such as the internal pattern, may be placed at the first tier of the hierarchy. From there, the subsequent tier may include one or more of the next most general patterns that are derived from the first tier pattern. That is, the organization at step (116) is not based on a ranking of the patterns, such as the ranking that may be performed at step (114). Although a ranking is not required for organizing the generated grammatical patterns into a hierarchy at step (116), steps (114) and (116) may be performed simultaneously or sequentially, in any order, in order to both rank the generated grammatical patterns and organize the generated patterns to perform a more detailed analysis. A more detailed description of the organization of the generated set of grammatical patterns in the hierarchy will be described below with references to
Then ranked patterns at step (114) and/or the organized patterns at step (116) are visually displayed (118). For example, the ranked and/or organized patterns may be displayed in a manner similar to the illustrative embodiments depicted in
With reference to
Input data in the form of corpus of text is shown at (320). In this example, the corpus of text states “find that myosin contributes to.” The annotated entity is “myosin” and the context is “find that < > contributes to.” In one embodiment, the annotated entity represents the internal pattern, and the context represents the external pattern. Based on the example corpus of text shown herein, the internal surface-level pattern (312) that corresponds to the corpus (320) is <myosin>, and the internal part-of-speech-level pattern (314) that corresponds to the corpus (320) is <NN>. As is known in the art, <NN> designates a singular common noun (as opposed to a singular proper noun, which is designated as “NNP”). Accordingly, in this example, the internal surface-level pattern is the annotated entity (i.e., the term), and the internal part-of-speech-level pattern designates the part of speech of the annotated entity (i.e., a semantic-level pattern of the term).
As further shown, the external surface-level pattern (316) that corresponds to the corpus (320) is “find that <gene1> contributes to.” One example of an external part-of-speech-level pattern (318) that corresponds to the corpus (320) is “VBP DT<gene1> VBZ TO.” As is known in the art, “VBP” designates a present tense verb that is not third person singular, “DT” designates a determiner, “VBZ” designates a third person singular present tense verb, and “TO” designates the use of “to” as a preposition or infinitive marker. In this example, the external surface-level pattern is an external term combined with the associated context, and the external part-of-speech-level pattern designates the parts of speech of the external surface-level pattern. Accordingly, the external part-of-speech-level pattern may be viewed as a generalized version of the external surface-level, or term-level, pattern.
The external part-of-speech-level pattern (318) is not intended to be limiting. Other examples of external part-of-speech-level patterns include VBP DT<gene1>, DT<gene1>, <gene1> VBZ TO, <gene1> VBZ, etc. That is, multiple external part-of-speech-level patterns may be generated from the context, ranging in various levels of generality.
The input to the generated external patterns, <gene1>, represents a one-token gene. That is, the external patterns will be generated based around a one-term gene phrase. In other embodiments, a two-term gene phrase, <gene2>, may be used as an input, a three-term gene phrase, <gene3>, may be used as an input, etc.
Once a desired number of external patterns are generated, they may be organized into a hierarchy. With reference to
There are four tiers shown in this example hierarchy. The third tier, Tier2 (430), corresponds to patterns that may be generated from sub-patterns of the second tier (420), such as nodes (422) and (424). As shown, the third tier (430) includes two nodes (432) and (434). Node (432) is shown at (436) as related to the sub-pattern shown in node (422) in the second tier (420). Node (432) corresponds to the pattern “<gene> expresses.” In this example, and as previously discussed, “VBZ” designates a third person singular present tense verb. The verb “expresses” is a specific version of the more general VBZ-type verb. It is to be understood that the verb “expresses” is being used herein as an example, and it is to be appreciated that any third person singular present tense verb may be considered with respect to pattern generation and organization
Node (434) is shown at (438a) and (438b) as related to the sub-patterns shown in nodes (422) and (424) in the second tier (420), respectively. Node (434) corresponds to the pattern “IN<gene> VBZ.” In this example, node (434) corresponds to a combination pattern generated from nodes (422) and (424). Specifically, in this example, node (434) corresponds to a hybrid pattern. The pattern in node (434) is provided to illustrate an example of a hybrid pattern. In an alternative embodiment, the pattern in node (434) may correspond to a combination pattern generated from more than two nodes, or a more specific version of the pattern in node (424), such as “VBN IN<gene>.” It is to be understood that the hybrid pattern in node (434) is an example of one pattern that may be generated, and it is to be appreciated that other and/or additional patterns may be generated from the pattern shown in node (422) and/or the pattern shown in node (424). Accordingly, external grammatical patterns may be generated based on a combination of two or more external grammatical patterns.
The example hierarchy shown herein includes four tiers, with the fourth tier referred to as Tier3 (440). This tier is shown with a single node (442) that corresponds to the pattern “NN NN VBN IN<gene> VBZ IN.” That is, the pattern in node (442) corresponds to “singular noun, singular noun, past participle verb, preposition/conjunction, <gene>, 3rd person singular present tense verb, preposition/conjunction.” The pattern in node (442) is provided to illustrate a specific part-of-speech-level pattern based on a more generalized part-of-speech-level pattern. It is to be understood that the specific pattern in node (442) is just one example of a pattern that may be generated and organized within the hierarchy, and it is to be appreciated that other and/or additional patterns may be generated. The goal of the hierarchy is to find a pattern that is most applicable to the input corpus text. The leaf node at (442) is a representation of the pattern that is most applicable to the input corpus text shown at (320).

Host (502) may be described in the general context of computer system-executable instructions, such as program modules, being executed by a computer system. Generally, program modules may include routines, programs, objects, components, logic, data structures, and so on that perform particular tasks or implement particular abstract data types. Host (502) may be practiced in distributed cloud computing environments where tasks are performed by remote processing devices that are linked through a communications network. In a distributed cloud computing environment, program modules may be located in both local and remote computer system storage media including memory storage devices.
As shown in
Memory (506) can include computer system readable media in the form of volatile memory, such as random access memory (RAM) (512) and/or cache memory (514). Host (502) further includes other removable/non-removable, volatile/non-volatile computer system storage media. By way of example only, storage system (516) can be provided for reading from and writing to a non-removable, non-volatile magnetic media (not shown and typically called a “hard drive”). Although not shown, a magnetic disk drive for reading from and writing to a removable, non-volatile magnetic disk (e.g., a “floppy disk”), and an optical disk drive for reading from or writing to a removable, non-volatile optical disk such as a CD-ROM, DVD-ROM or other optical media can be provided. In such instances, each can be connected to bus (508) by one or more data media interfaces. As will be further depicted and described below, memory (506) may include at least one program product having a set (e.g., at least one) of program modules that are configured to carry out the functions of the embodiments described herein. In one embodiment, a corpus of text (522) is stored in one or more components of memory (506) upon receipt.
Program/utility (518), having a set (at least one) of program modules (520), may be stored in memory (506) by way of example, and not limitation, as well as an operating system, one or more application programs, other program modules, and program data. Each of the operating systems, one or more application programs, other program modules, and program data or some combination thereof, may include an implementation of a networking environment. Program modules (520) generally carry out the functions and/or methodologies of embodiments as described herein. For example, the set of program modules (520) may include at least one module that is configured to analyze the received corpus of text, extract a set of features of the corpus, generate a set of grammatical patterns based on the extracted set of features, organize the generated grammatical patterns into a hierarchy, and rank the generated grammatical patterns. The hierarchy of patterns (524) may be stored in one or more components of memory (506).
Host (502) may also communicate with one or more external devices (540), such as a keyboard, a pointing device, etc.; a display (550); one or more devices that enable a user to interact with host (502); and/or any devices (e.g., network card, modem, etc.) that enable host (502) to communicate with one or more other computing devices. Such communication can occur via Input/Output (I/O) interface(s) (510). Still yet, host (502) can communicate with one or more networks such as a local area network (LAN), a general wide area network (WAN), and/or a public network (e.g., the Internet) via network adapter (530). As depicted, network adapter (530) communicates with the other components of host (502) via bus (508). In one embodiment, the corpus of text (522) may be received by a server and communicated by the network adapter (530) to memory (506) via bus (508) for storage. It should be understood that although not shown, other hardware and/or software components could be used in conjunction with host (502). Examples, include, but are not limited to: microcode, device drivers, redundant processing units, external disk drive arrays, RAID systems, tape drives, and data archival storage systems, etc. In one embodiment, the ranked patterns and/or the organized patterns may be visually output on the display (550).
As is known in the art, cloud computing is a 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. This cloud model may include at least five characteristics, at least three service models, and at least four deployment models. Example of such characteristics are as follows:
On-demand self-service: a cloud consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human interaction with the service's provider.
Broad network access: capabilities are available over a network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g., mobile phones, laptops, and PDAs).
Resource pooling: the provider's computing resources are pooled to serve multiple consumers using a multi-tenant model, with different physical and virtual resources dynamically assigned and reassigned according to demand. There is a sense of location independence in that the consumer generally has no control or knowledge over the exact location of the provided resources but may be able to specify location at a higher level of abstraction (e.g., country, state, or datacenter).
Rapid elasticity: capabilities can be rapidly and elastically provisioned, in some cases automatically, to quickly scale out and rapidly released to quickly scale in. To the consumer, the capabilities available for provisioning often appear to be unlimited and can be purchased in any quantity at any time.
Measured service: cloud systems automatically control and optimize resource use by leveraging a metering capability at some level of abstraction appropriate to the type of service (e.g., storage, processing, bandwidth, and active user accounts). Resource usage can be monitored, controlled, and reported providing transparency for both the provider and consumer of the utilized service.
Service Models are as follows:
Software as a Service (SaaS): the capability provided to the consumer is to use the provider's applications running on a cloud infrastructure. The applications are accessible from various client devices through a thin client interface such as a web browser (e.g., web-based email). The consumer does not manage or control the underlying cloud infrastructure including network, servers, operating systems, storage, or even individual application capabilities, with the possible exception of limited user-specific application configuration settings.
Platform as a Service (PaaS): the capability provided to the consumer is to deploy onto the cloud infrastructure consumer-created or acquired applications created using programming languages and tools supported by the provider. The consumer does not manage or control the underlying cloud infrastructure including networks, servers, operating systems, or storage, but has control over the deployed applications and possibly application hosting environment configurations.
Infrastructure as a Service (IaaS): the capability provided to the consumer is to provision processing, storage, networks, and other fundamental computing resources where the consumer is able to deploy and run arbitrary software, which can include operating systems and applications. The consumer does not manage or control the underlying cloud infrastructure but has control over operating systems, storage, deployed applications, and possibly limited control of select networking components (e.g., host firewalls).
Deployment Models are as follows:
Private cloud: the cloud infrastructure is operated solely for an organization. It may be managed by the organization or a third party and may exist on-premises or off-premises.
Community cloud: the cloud infrastructure is shared by several organizations and supports a specific community that has shared concerns (e.g., mission, security requirements, policy, and compliance considerations). It may be managed by the organizations or a third party and may exist on-premises or off-premises.
Public cloud: the cloud infrastructure is made available to the general public or a large industry group and is owned by an organization selling cloud services.
Hybrid cloud: the cloud infrastructure is a composition of two or more clouds (private, community, or public) that remain unique entities but are bound together by standardized or proprietary technology that enables data and application portability (e.g., cloud bursting for load balancing between clouds).
A cloud computing environment is service oriented with a focus on statelessness, low coupling, modularity, and semantic interoperability. At the heart of cloud computing is an infrastructure comprising a network of interconnected nodes.

The flow charts 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. In this regard, each block in the flow charts or block diagrams may represent a module, segment, or portion of code, which comprises one or more executable instructions for implementing the specified logical function(s). It should also be noted that, in some alternative implementations, the functions noted in the block 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 flow chart illustration(s), and combinations of blocks in the block diagrams and/or flow chart illustration(s), can be implemented by special purpose hardware-based systems that perform the specified functions or acts, or combinations of special purpose hardware and computer instructions.
The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting. 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.
The embodiments described herein may be implemented in a system, a method, and/or a computer program product.
