Patent number: 9984064Abstract: An alignment of attributes is extracted from a pair of mentions in an annotated corpus. An annotated document is read from the annotated corpus. Three character string arrays (A, B, and C) are stored into a first TRIE. The character string arrays include character string representations of attributes of one or more first tokens, second tokens, and neighborhood tokens of mentions of the annotated document, respectively. The storing into the first TRIE obtains partial integer arrays (K, L, and M) that include identifiers corresponding to the attributes of the mentions. The partial integer arrays are stored into a second TRIE. The storing into the second TRIE obtains an identifier array (X) that includes three identifiers. The identifier array is stored into a third TRIE. The storing into the TRIE obtains one identifier of the alignment of attributes.Type: GrantFiled: November 11, 2015Date of Patent: May 29, 2018Assignee: International Business Machines CorporationInventors: Ken Kumagai, Akihiro Nakayama

Patent number: 8131537Abstract: To improve the processing speed of a morphological analysis system, an analysis processing part retrieves words constituting a natural language sentence from a word dictionary, retrieves concatenation rules from a grammar dictionary, creates an automaton based on the words and the concatenation rules, and obtains a morphological analysis. The grammar dictionary stores rules integrating concatenation rules representing non-null transitions and concatenation rules representing null transitions in which transition sources of the first concatenation rule are their transition destinations. To create the automaton, an optimal solution searching part of the analysis processing part generates, responsive to an input word entered into the automaton, states necessary for transition according to the concatenation rules corresponding to the input word without generating any state that can be transited by pursuing a null transition succeeding the generated states.Type: GrantFiled: October 12, 2004Date of Patent: March 6, 2012Assignee: International Business Machines CorporationInventor: Akihiro Nakayama

Patent number: 7684976Abstract: A regular-expression dictionary, as opposed to an exact-match dictionary, is constructed for utilization within computerized textual analysis. One or more data types are defined for entries within the regular-expression dictionary, within a markup-language schema. A structure in the markup-language schema is provided that encompasses the data types of the entries within the regular-expression dictionary. For each of a number of entries of the regular-expression dictionary, a mapping methodology is defined between a source definition of the entry to the structure and the data types within the markup-language schema. Furthermore, a definition of the entry is mapped to the data types within the structure of the markup-language schema, using the mapping methodology defined. The markup language may be eXtensible Markup Language (XML), or another type of markup language.Type: GrantFiled: May 13, 2006Date of Patent: March 23, 2010Assignee: International Business Machines CorporationInventor: Akihiro Nakayama

Patent number: 6161533Abstract: A managing system for managing slurry, which is supplied to a wire saw. Slurry is prepared in a preparing tank and sent to the wire saw and used to cut workpieces. After usage for cutting workpieces, the slurry is sent to a separating apparatus from the wire saw. The separating apparatus separates impurities from the used slurry to recover a mixture of recyclable dispersing liquid and abrasive grains from the used slurry. The recovered mixture is returned to the preparing tank. The recovered mixture is mixed with fresh abrasive grains and dispersing liquid in the preparing tank to prepare slurry. The property (specific gravity and viscosity) of the slurry in the preparing tank is detected. The amount of fresh abrasive grains and dispersing liquid supplied to the preparing tank is adjusted in accordance with the detection results. Accordingly, slurry having properties that are optimal for the cutting of workpieces is prepared.Type: GrantFiled: February 25, 1999Date of Patent: December 19, 2000Assignees: Nippei Toyoma Corp., Toyobo Co., Ltd.Inventors: Noboru Katsumata, Kensho Miyata, Kazutomo Kinutani, Kensho Kuroda, Toyotaka Wada, Akihiro Nakayama, Katsumasa Takahashi, Takaharu Nishida, Shouichi Uemura, Tetsuo Kodama

Patent number: 5950643Abstract: A processing system for processing of wafers that are formed by slicing a cylindrical workpiece which is adhered to a support plate by an adhesive agent. The processing system includes a washing apparatus, a removing apparatus, a separating apparatus, and a transferring apparatus. The washing apparatus washes the wafers that are remained adhered to the support plate. The removing apparatus removes a group of the wafers from the support plate. The removed wafers are gathered in a cylindrical shape. The separating apparatus separates the wafers one by one. The separating apparatus includes a vessel for accommodating the wafers separated one from another.
