  • Publication number: 20180140257
    Abstract: Embodiments relate to digital image processing for diagnosis of a subject. More specifically, the embodiments relate to automation of diagnoses through data interpretation. An image is acquired from the subject. Elements are recognized within the image based on morphological features. The image is compared to learned data. Based on the comparison, a probability of a potential diagnosis(es) is calculated. A diagnosis of the subject is determined based on the potential diagnosis(es) and the calculated probability. The diagnosis may be changed based on a new image acquired from the subject.

  • Patent number: 9953027
    Abstract: A system includes a question answering system executed by a computer, a processor, and a memory coupled to the processor. The memory is encoded with instructions that when executed cause the processor to provide training for training the question answering system. The training system is configured to receive a plurality of bidirectional disjunctive logical forms which include two directional disjunctions of differences between a first logical form of a first sentence and second logical form of a second sentence, realize the plurality of bidirectional disjunctive logical forms to generate a first plurality of paraphrases of the first and second sentence, score each of the first plurality of paraphrases based on textual similarity between the first plurality of paraphrases and the first and second sentences, and prune the first plurality of paraphrases to generate a second plurality of paraphrases based on the scores of each of the first plurality of paraphrases.

  • Publication number: 20180095962
    Abstract: A natural language query (NLQ) is translated to a structured data query (e.g., a SQL statement) by extracting entities from the NLQ and replacing them with generic variables to form a generic query. The generic query is associated with a structured question type which includes structured data variables using natural language classifiers (NLCs). Specific data is inserted in the structured question type in relation to the structured data variables based on the extracted entities to form the structured data query. An ensemble of NLCs trained with different ground truths can be used to yield multiple candidate question types. One of the candidate question types is selected based on confidence levels. The multiple NLCs can include an NLC which is optimized according to a focus of the generic query. For example, an NLC can be optimized for a specific data structure (such as SQL), or for comparative queries.

  • Publication number: 20180081628
    Abstract: A method, system and computer-usable medium are disclosed for preserving temporal relevance in a response to a query. A query is processed to extract first temporal features, which is then used to identify first documents within a corpus. The first documents are processed to generate first metadata and mined content, which is processed with the first temporal features to generate second documents having second temporal features corresponding to the first temporal features. The corpus is updated with new documents and revisions to the first documents to generate second documents. In turn, the second documents are processed to generate second metadata and mined content, which is then used to generate a ranked list of temporally-relevant documents.

  • Publication number: 20180081627
    Abstract: A method, system and computer-usable medium are disclosed for preserving temporal relevance of content within a corpus. A corpus is processed to generate temporally-relevant metadata and mined content, which in turn are processed to generate first temporal relevancy metrics. The cache history of a web browser is likewise processed to generate second temporal relevancy metrics, which in turn is processed with the first temporal relevancy metrics to generate first temporal relevancy scores. New documents are ingested into the corpus and existing documents are revised. Temporally-relevant metadata and mined content associated with the updated corpus are then processed to generate third temporal relevancy metrics. The second and third temporal relevancy metrics are then processed to generate second temporal relevancy scores, which is then used to provide a temporally-relevant response to a query.

  • Publication number: 20180075015
    Abstract: A system includes a question answering system executed by a computer, a processor, and a memory coupled to the processor. The memory is encoded with instructions that when executed cause the processor to provide training for training the question answering system. The training system is configured to receive a first phrase and a second phrase, the first and second phrases being paraphrases of each other, convert the first phrase into a first logical form and the second phrase into a second logical form, generate a phrasal edit that includes a difference between the first logical form and the second logical form, convert the phrasal edit into a disjunctive logical form in two directions, and generate a first plurality of paraphrases of the first and second phrases based on the disjunctive logical form.

  • Patent number: 9886501
    Abstract: A method, system and computer-usable medium are disclosed for using a contextual graph to summarize a corpus of content. Natural Language Processing (NLP) preprocessing operations are performed on text within an input corpus to form a grammatical analysis. In turn, the grammatical analysis is used to generate semantic associations between phrases in the input corpus. The resulting semantic associations are then used to determine the thematic relevance of the individual sentences in the input corpus to form a context-based ranking. In turn, the context-based ranking is used to construct a context graph, the vertices of which are represented by phrases, and the edges are represented by an aggregate score resulting from performing calculations associated with semantic similarity of the phrases. The resulting context graph is then used to generate a content summarization for the input corpus.

  • Patent number: 9881082
    Abstract: A method, system and computer-usable medium are disclosed for generating a context-sensitive summarization of a corpus of content. Natural Language Processing (NLP) operations are performed on text within an input corpus to extract phrases, which are then used to generate a grammatical analysis. In turn, the grammatical analysis is used to determine the thematic relevance of individual sentences in the input corpus. Sentences within the input corpus are then ranked according to their respective thematic relevance. This ranking is used to construct a contextualized content graph, which in turn is used to generate a content summarization for the input corpus.

  • Publication number: 20170322939
    Abstract: Answer effectiveness evaluations include providing, by a computing device, an answer to a search query received from a user, and in response to receiving a subsequent search query from the user, determining by the computing device a level of effectiveness of the answer to the search query with respect to the user. The determination includes comparing aspects of the search query to aspects of the subsequent search query, calculating, based on the comparing, a relevance score that indicates a measure of similarity between the aspects of the search query and the aspects of the subsequent search query, and determining that the answer effectively answers the search query when the relevance score exceeds a threshold value.
