Patent number: 11055338Abstract: Embodiments of the present invention include generating a facet tree based on words found in one or more documents, the facet tree being a tree data structure that defines hierarchical relationships between a plurality of words. The method may further include calculating a degree of similarity between a first word and a second word based on similarity of usage of the first word and the second word in the one or more documents, and generate a facet tree based on the degree of similarity. The method may further include, for each of one or more candidate words in the one or more documents, calculating a degree of correlation between a co-occurrence of two or more existing facet tree entries in a document and an occurrence of the candidate word in the document, and updating the facet tree on the basis of the one or more degrees of correlation.Type: GrantFiled: November 26, 2019Date of Patent: July 6, 2021Assignee: International Business Machines CorporationInventors: Yasumasa Kajinaga, Yutaka Moriya, Yuichi Suzuki

Patent number: 10956470Abstract: Facet-based query refinement based on multiple query interpretations is provider through a process that includes receiving a query for querying documents, of a whole document set, that deviate by one or more facet values. The process generates different query interpretations from query text of the query. The process executes the different query interpretations to obtain resulting document sets. For each different query interpretation, the executing executes the query interpretation to obtain a resulting document set corresponding to that query interpretation, and identifies facet values represented in the resulting document set. The process builds and presents to a user a query refinement interface, presenting the different query interpretations and properties of the resulting document sets, as well as, for each of the one or more facet values, and relative to each other, facet value representation of the facet value in each of the resulting document sets.Type: GrantFiled: June 26, 2018Date of Patent: March 23, 2021Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Hiroaki Kikuchi, Yutaka Moriya

Patent number: 10282418Abstract: A mechanism is provided in a data processing system comprising at least one processor and at least one memory, the at least one memory comprising instructions executed by the at least one processor to cause the at least one processor to implement a document analysis device for performing a statistical analysis of documents with respect to a facet. An acceptance module accepts a natural language sentence. An extraction module extracts a first facet from the natural language sentence. A statistical analysis module performs a first statistical analysis of a set of documents with respect to the first facet and determines a value of the first facet based on a result of the first statistical analysis responsive to information being extracted from the natural language sentence, the information requesting for a second statistical analysis. The statistical analysis module performs the second statistical analysis of the set of documents using the value of the first facet.Type: GrantFiled: June 19, 2017Date of Patent: May 7, 2019Assignee: International Business Machines CorporationInventors: Shunsuke Ishikawa, Hiroaki Kikuchi, Masaki Komedani, Yutaka Moriya
