Patent number: 12210538Abstract: Techniques for enhanced table and text question answering based on multi-instance, multi-answer training are presented. An answer extractor component can determine answer scores associated with candidate answer data items based on analysis of a set of data, comprising row data items of a table and passage data items associated with the table, and a context of a query of the set of data. The answer extractor component can be trained based on application of denoised single-instance and multiple-instance answer matching data associated with contexts to an answer extractor model to generate a trained answer extractor model of the answer extractor component. A query response component can determine a correct answer data item responsive to the query from the candidate answer data items based on the answer scores associated with the candidate answer data items, wherein the candidate answer data items can be reranked based on reweighted answer scores.Type: GrantFiled: November 8, 2022Date of Patent: January 28, 2025Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Vishwajeet Kumar, Saneem Ahmed Chemmengath, Jaydeep Sen

Publication number: 20240370471Abstract: Retrieval aware natural language question generation for open domain document retrieval is provided. In one aspect, a system for retrieval aware question generation includes: a question decontextualizer configured to decontextualize a question generated from a context of a target document by adding terms from the context into the question itself to create a decontextualized question, where the decontextualized question alone enables open domain document retrieval without a need for also providing the context. The system can also include a detect document identifier configured to find the terms in the context; and a retriever configured to retrieve documents from the corpus of documents using the decontextualized question. A method for retrieval aware question generation using the present system is also provided.Type: ApplicationFiled: May 5, 2023Publication date: November 7, 2024Inventors: Saneem Ahmed Chemmengath, Vishwajeet Kumar, Jaydeep Sen
