摘要： A cognitive system improves the accuracy of a natural language statement by analyzing relationships between entities in a knowledge graph for the statement. A natural language processing engine extracts entities and relationships in the statement, and a yes/no pipeline gauges the accuracy of the statement. If a statement is deemed inaccurate, the knowledge graph is used to identify a predominant relationship between certain entities, and a candidate phrase representing the predominant relationship is generated and presented to the user as a suggested replacement for a target phrase in the statement representing the relationship. The yes/no pipeline computes an accuracy score for the statement, and the statement is deemed inaccurate when the score is below a programmable threshold. The assertiveness of the system can be tuned by requiring the accuracy score of a proposed modified statement to be greater than the score of the original statement plus some tuning factor.

摘要： A video conferencing system includes a processing device and a memory device and is configured to manage a video conference to manage a video conference feed to a plurality of participant devices. The system includes an interface control module that receives a plurality of video feeds and audio feeds associated with participants to the video conference, and generates a video conference feed including a video conference interface for being displayed to the plurality of participants. The system also includes a context analysis module that analyzes the audio feeds to identify contextual information associated with the conversation. The system further includes a participant modeling module that calculates a topic relevance score for each of the plurality of participants based on the contextual information. During a video conference, the interface control module emphasizes a video feed of a participant associated with a topic relevance score greater than a threshold.

摘要： Embodiments relate to an intelligent computer platform to use ground truth data to rate source reliability, and application of the source reliability. A computer system, computer program product, and computer implemented method apply the ground truth data to evaluate a document and statements therein, and dynamically apply the assessed reliability. The assessed reliability is dynamically applied to a source, with the application yielding acceptance of the document to the source based on the applied reliability assessment.

摘要： A mechanism is provided for routinely evaluating an accuracy of a request processing pipeline. A set of questions is executed through the request processing pipeline, producing a list of answers, supporting documents, and accuracy metrics. A determination is made as to whether a document contribution value of each document associated with the answer is equal to or above a document contribution threshold value. For those documents equal to or above the document contribution threshold value, a snapshot is stored in a training-data data structure. Based on a clustering of questions, for each question cluster, a determination is made of an average accuracy metric. A comparison is performed and a determination is made as to whether an accuracy metric delta exceeds the accuracy metric threshold value. If so, a differential report is generated indicating a review is needed of a training of the request processing pipeline.

摘要： Embodiments relate to an intelligent computer platform to identify and evaluate candidate passages response data in natural language form. A passage is analyzed by applying input tokens against passage tokens. A structure representing the analyzed passage is populated with of matching input and passage tokens. The input and passage tokens are used to assess the structure. First and second counts of token matching criteria are determined, including a first count of matching token entries and a second count of evaluated token entries. An alignment of the passage to a candidate question is calculated and a ratio of the first and second counts is assessed. Data from the passage are returned with the ratio.

摘要： A method, system and computer program product are provided for implementing misleading title identification. A title and a list of passages are received. The title is supplied to a question answering factoid pipeline as a question. The title is analyzed against the list of passages or content as an answer source material. A respective answer score of all passages is compared with a tunable threshold to identify titles that are misleading or inaccurate based on the content of all passages. A selected action for the identified misleading titles is provided for a user.

摘要： An approach is provided that receives words that are input by a user of an application with the words being displayed on a display device. Each of the words are compared to words from a dictionary. Based on the comparisons, words that are not found in the dictionary and only appear a single time are highlighted as being misspelled words. However, words that are not in the dictionary but appear multiple times in the document are highlighted differently to indicate that these words are possible misspelled words with the difference in highlighting allowing the user to easily discern between misspelled and possibly misspelled words.

摘要： A computer-implemented method includes dividing a textual representation of a media content into a plurality of portions separated at temporal boundaries of the media content and performing an analysis of each portion of the plurality of portions of the textual representation of the media content to determine a characteristic associated with each respective portion of the textual representation of the media content, generating a multi-dimensional model assigning each determined characteristic to each associated respective portion of the plurality of portions of the textual representation of the media content, the multi-dimensional model identifying each determined characteristic and the temporal boundaries to enable control of an environmental control device to modify an environment proximate to a user based on the multi-dimensional model, and transmitting the multi-dimensional model to a user equipment configured to control the environmental control device to modify the environment proximate to the user based on the multi-dimensional model.

摘要： An approach is provided that receives a question at a question-answering (QA) system. The received question includes one or more terms, and the question pertains to a subject matter domain that is supported by the QA system. Analyzing a number of expressions included in a set of question-answer pairs (QA pairs), with the QA pairs being ground-truths established to in support of the subject matter domain. The analysis identifies whether a selected term from the question is a synonym for any of the expressions. The expressions that are identified as synonyms are then used in a QA pipeline that generates one or more candidate answers to the received question.
