  • Patent number: 11055338
    Abstract: 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.

  • Patent number: 10956470
    Abstract: 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.

  • Patent number: 10282418
    Abstract: 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.

  • Publication number: 20140306998
    Abstract: A computer is disclosed that performs a land boundary display process. The computer executes an imaging process when an imaging request is detected. The computer specifies an imaging range based on a location, an imaging orientation and an elevation angle of a terminal apparatus when the imaging process is executed. Also, the computer specifies an area corresponding to a plot of land in a captured imaged based on the imaging range being specified. After that, the computer reads out boundary line information of the plot of land corresponding to latitude and longitude information from a storage part, and generates an image by overlapping an area corresponding to the plot of land being specified with the boundary line information being read out. Then, the computer displays the image at a display device.
