Publication number: 20170053039Abstract: Embodiments relate to generating a retrieval condition for retrieving a target character string from texts by pattern matching. An aspect includes dividing a first text into words. Another aspect includes generating a converted character string by performing at least one of appending at least one character in at least either one of previous and subsequent positions of the target character string. Another aspect includes replacing at least one character of the target character string. Another aspect includes generating the retrieval condition for retrieval candidates in the words of the first text, the retrieval condition comprising determining that a retrieval candidate matches the target character string and does not match the converted character string based on a ratio of a part of the retrieval candidate which matches the converted character string and corresponds to the target character string is less than or equal to a reference frequency.Type: ApplicationFiled: November 9, 2016Publication date: February 23, 2017Inventors: Emiko Takeuchi, Daisuke Takuma, Hirobumi Toyoshima

Publication number: 20150026553Abstract: A hardware device analyzes a document that includes a text-based visual representation. A correspondence information hardware storage device holds known representations of graphical images as text-based visual representations. The graphical images depict portraits of physical objects. The text-based visual representations are associated with information that each describe one of the physical objects. An identification hardware device identifies a text-based visual representation within a document. The identification hardware device matches the text-based visual representation within the document to one or more of the text-based visual representations stored in the correspondence information hardware storage device. An editing hardware device retrieves information from the correspondence information hardware storage device that is identified, by the identification hardware device, as describing a text-based visual representation component within the document.Type: ApplicationFiled: July 14, 2014Publication date: January 22, 2015Inventors: Emiko Takeuchi, Daisuke Takuma, Hirobumi Toyoshima

Patent number: 8538745Abstract: A computer system of an embodiment of the disclosure can be used to automatically create or populate a terms dictionary using a set of computing units. A morphological analysis unit can acquire token sequence data by performing morphological analysis for the text data. A category distinguishing unit can distinguish tokens of the token sequence data by using a category dictionary to extract uncategorized words. An uncategorized-word comparing unit can compare each of the extracted uncategorized words with an uncategorized-word comparison rule to extract an uncategorized word matching the uncategorized-word comparison rule as a registration candidate word. A token-sequence comparing unit can compare a token sequence of the token sequence data with a token-sequence comparison rule to extract a token sequence matching the token-sequence comparison rule as registration candidate words. A permission unit can permit a user to select whether to register the registration candidate words in the category dictionary.Type: GrantFiled: January 4, 2010Date of Patent: September 17, 2013Assignee: International Business Machines CorporationInventors: Hiroki Oya, Daisuke Takuma, Hirobumi Toyoshima

Patent number: 7945552Abstract: A system of the present invention stores: a first index which designates lists of keywords contained in texts from identifications of the respective texts; a second index which designates lists of texts containing keywords from identifications of the respective keywords; and the number of texts containing the respective keywords. Then, upon receiving an input of a text search condition, the system calculates an estimation of search time by the first index and an estimation of search time by the second index, and determines which one of the first and second indexes makes a search faster. Then, by using the index which has been determined to make the search faster, the system searches for keywords which appear in texts satisfying the text search condition with higher frequency.Type: GrantFiled: March 26, 2008Date of Patent: May 17, 2011Assignee: International Business Machines CorporationInventors: Daisuke Takuma, Issei Yoshida, Yuta Tsuboi
