Patent number: 11687514Abstract: Multimodal table encoding, including: Receiving an electronic document that contains a table. The table includes multiple rows, multiple columns, and a schema comprising column labels or row labels. The electronic document includes a description of the table which is located externally to the table. Next, operating separate machine learning encoders to separately encode the description, schema, each of the rows, and each of the columns of the table, respectively. The schema, the rows, and the columns are encoded together with end-of-column tokens and end-of-row tokens that mark an end of each column and row, respectively. Then, applying a machine learning gating mechanism to the encoded description, encoded schema, encoded rows, and encoded columns, to produce a fused encoding of the table, wherein the fused encoding is representative of both a structure of the table and a content of the table.Type: GrantFiled: July 15, 2020Date of Patent: June 27, 2023Assignee: International Business Machines CorporationInventors: Roee Shraga, Haggai Roitman, Guy Feigenblat, Mustafa Canim

Patent number: 11681876Abstract: An embodiment calculates a point of view (POV) value for a subportion of an item of media content, including evaluating user inputs related to an automatically detected POV of the subportion of the item. The embodiment also calculates a non-factual cost for the subportion of the item indicative of an amount of the subportion of the item that lacks support in a fact-based corpora. The embodiment also performs a cascaded summarization process comprising generating a summary of the item using the subportion of the item and a summarization technique, analyzing the summary using a fact-checking algorithm to determine whether the summary satisfies a factual score threshold, and performing a next iteration of the cascaded summarization process while the summary fails to satisfy the factual score threshold. The embodiment also communicates a summary satisfying the factual score threshold to a user device.Type: GrantFiled: October 22, 2020Date of Patent: June 20, 2023Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Aaron K Baughman, Sai Krishna Reddy Gudimetla, Nicholas Michael Wilkin, Guy Feigenblat

Publication number: 20230146979Abstract: In an approach to improve abstract summarization with question and answer rewards embodiments generate, by a question and answer generator, questions and answers corresponding to a generated summary. Further, embodiments evaluate received answers for the generated questions by analyzing received answers associated with the generated summary against answers received for an original summary, and calculate a reward based on the similarity between answers associated with generated summary and the original summary. Additionally, embodiments update the generation model by applying the calculated reward to further train the summary generation model.Type: ApplicationFiled: November 6, 2021Publication date: May 11, 2023Inventors: Chulaka Gunasekara, Guy Feigenblat, Benjamin Sznajder, Sachindra Joshi
