Abstract: A system comprising a memory storing an inverted index of a corpus of documents, and a processor coupled to the memory and configured to receive a search query, after receiving the search query identify a first subset of documents that include the search query by searching, based on the search query, the inverted index of the corpus of documents, wherein the corpus of documents includes the first subset of documents, process the first subset of documents to identify entities related to the search query and relations between the entities and the search query, and generate a knowledge graph based on the entities and the relations.

Abstract: A computer-implemented method that includes receiving a search query and, after receiving the search query, identifying a first subset of documents that include the search query by searching, based on the search query, an inverted index of a corpus of documents that includes the first subset of documents. The computer-implemented method additionally includes processing the first subset of documents to identify entities related to the search query and relations between the entities and the search query. The computer-implemented method additionally includes generating a knowledge graph based on the entities and the relations.

Abstract: A method for merging incoming alerts for accessibility is described. Two input alerts intended for presentation by a screen reader are received. If the two input alerts have arrived with a specified time interval, the two input alerts are combined into an output alert. The output alert is sent to a screen reader for presentation.

Abstract: The disclosed embodiments include a Question and Answer (QA) system, computer program product, and computer-implemented method configured to adjust passage relevancy to a question based on time. The disclosed embodiments seek to improve the process of providing answers to questions that include a temporal reference. In particular, the disclosed embodiments are better able to provide answers to questions that include a temporal reference that does not have an exact matching temporal reference in an answer source of a QA system.
