Publication number: 20200097596Abstract: A computer-implemented method for extracting semantic relations is disclosed. In the method, a plurality of hierarchal structures that originates from a corpus of documents is obtained. Each hierarchal structure includes a plurality of elements having respective recitations included in a corresponding document. In the method, for each predetermined relationship between ancestor and descendant elements in the hierarchal structures, a first keyword list is extracted from the ancestor element and a second keyword list is extracted from the descendant element. A statistical index is calculated for each pair of first and second keywords using the first keyword lists and the second keyword lists. The index indicates a strength of association between the first and second keywords. In the method, a candidate list of keyword pairs having semantic relationships is output using the statistical index calculated for each pair.Type: ApplicationFiled: September 20, 2018Publication date: March 26, 2020Inventors: Shoko Suzuki, Tetsuya Nasukawa, Hiroshi Kanayama

Patent number: 9002695Abstract: Provided are two types of translation engines. One of the translation engines translates a text written in a source language X into an intermediate language C, and the other translates the intermediate language C into a target language Y. The X-C translation engine translates an original text written in the source language X into a text in a predetermined intermediate language C as well as acquires and adds annotations obtained by this translation to the translated text written in the intermediate language C. The C-Y translation engine references annotations, which are obtained by the X-C translation engine and added to the text in the intermediate language C, and translates the text in the intermediate language into a text in the target language Y sentence.Type: GrantFiled: May 12, 2004Date of Patent: April 7, 2015Assignee: International Business Machines CorporationInventors: Hideo Watanabe, Hiroshi Kanayama

Publication number: 20140104967Abstract: A data transfer device that transfers data to a memory according to an instruction from a processor via a bus through which a response indicating completion of data writing in the memory is not sent back, comprises an inter-memory data transfer control unit including an operation start trigger receiving unit, a parameter acquiring unit, a read unit, and a write unit. When the write unit detects switching of a write destination memory, the write unit confirms write completion as to the memory by a procedure different from writing. When a data transfer instructed by the processor is completed, the write unit confirms write completion as to the write destination memory at the end of the data transfer by the procedure different from writing. The inter-memory data transfer control unit notifies the processor of completion of an inter-memory data transfer based on the confirmation of the write completion.Type: ApplicationFiled: October 14, 2013Publication date: April 17, 2014Applicant: HITACHI, LTD.Inventors: Masahiro ARAI, Hiroshi HIRAYAMA, Masanori TAKADA, Hiroshi KANAYAMA, Hideaki FUKUDA

Patent number: 8495288Abstract: A storage controller of the present invention narrows down the target for data comparison by comparing hash codes beforehand and rapidly detects duplicated data. A hash value setting unit sets a hash code in data received from a host. Hash code-attached data is stored in a logical volume. A microprocessor unit compares the hash codes for each comparison-targeted data. When hash codes match with one another, a data comparator compares the target data, and determines whether or not the data is duplicated data. When duplicated data is detected, the microprocessor unit removes the duplicated data.Type: GrantFiled: June 10, 2008Date of Patent: July 23, 2013Assignee: Hitachi, Ltd.Inventors: Mutsumi Hosoya, Hiroshi Kanayama, Wataru Mineta
