Patent number: 7103536Abstract: If the character string is long, and when retrieving symbols containing characters of high frequency of appearance or character chain, high speed retrieval is possible up to infix matching, and a symbol dictionary of small capacity can be compiled. In the symbol dictionary compiling method of the invention, each symbol in symbol data is covered with shorter symbols called “meta-symbols” for covering the symbol in the symbol data, and the information showing how each symbol is covered is obtained by preparing meta-symbol appearance information recorded in each meta-symbol, and therefore high speed retrieval including up to infix matching is possible, and a symbol dictionary of small capacity can be compiled.Type: GrantFiled: November 30, 1999Date of Patent: September 5, 2006Assignee: Matsushita Electric Industrial Co., Ltd.Inventor: Yuji Kanno

Patent number: 7069005Abstract: A measuring section measures a digital multiplex signal divided into slot units, as a signal to be measured. A display control section displays, on a screen, a measured waveform of the signal. An analyzing section analyzes, in the slot units, information relating to the measured waveform of the signal. A storage section stores the information relating to the measured waveform of the signal which is analyzed in the slot units, as analyzed information of the slot unit. A marker display control section displays a slot marker to designate an arbitrary slot, in correspondence with the measured waveform of the signal which is displayed on the screen. A slot information display control section reads, from the storage section, the analyzed information of the slot unit corresponding to the slot designated by the slot marker displayed on the screen, and displays the analyzed information of the slot unit in correspondence with the slot marker.Type: GrantFiled: July 5, 2002Date of Patent: June 27, 2006Assignee: Anritsu CorporationInventors: Takayuki Morikawa, Katsuhisa Iiyoshi, Yuji Kanno, Hideo Zuinen

Patent number: 6671683Abstract: Three kinds of data, i.e., a keyword frequency-of-appearance, a document length, and a keyword weight, are produced. Then, a document profile vector and a keyword profile vector are calculated. Then, by independently performing the weighted principal component analysis considering the document length and the keyword weight, a document feature vector and a keyword feature vectors are obtained. Then, documents and keywords having higher similarity to the feature vectors calculated with reference to the retrieval and extracting conditions are obtained and displayed.Type: GrantFiled: June 28, 2001Date of Patent: December 30, 2003Assignee: Matsushita Electric Industrial Co., Ltd.Inventor: Yuji Kanno

Patent number: 6493713Abstract: A high-speed document retrieval system creates a regular expression dictionary and a word index on the basis of a retrieval document and a word dictionary to conduct retrieval to a document through the regular expression dictionary and the word index at a high speed. A regular expression dictionary expressing a set of character strings having the same length is created from a word dictionary. In terms of a character string included in a retrieval document and matching with a regular expression in the regular expression dictionary, an index element is recorded in a word index when there is no different index element which allows an observing index element to be deducible, which eventually produces a word index capable of achieving a high-speed full-text retrieval without the noticeable increase in the index capacity.Type: GrantFiled: May 30, 2000Date of Patent: December 10, 2002Assignee: Matsushita Electric Industrial Co., Ltd.Inventor: Yuji Kanno

Patent number: 6298344Abstract: A searching apparatus includes an index generation portion for generating an index to provide data of the number of documents including the key word and the number of appearances of the key word. Matching degrees between the key word and documents are calculated from the number of documents including the key word and the number of appearances of the key word. A portion of documents are arranged in order of the matching degree in a buffer which are outputted as the searching result. Lower rank documents regarding the matching degree are searched by comparing the lowest matching degree of the neighbour higher ranked document arranged in the buffer. At first time searching, data of the latest edition of the documents stored in a memory is detected and stored and is used to provide second time searching operation to eliminate inconsistency in the searching result between the editions at first and second time searching operations. The index is generated every field of each document.Type: GrantFiled: March 26, 1999Date of Patent: October 2, 2001Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Mitsuaki Inaba, Naohiko Noguchi, Yuji Kanno, Mitsuhiro Sato, Hayashi Ito

Patent number: 6212517Abstract: A system for providing keywords to facilitate a search in a text retrieval system. For each of texts constituting a text base, the system creates a word ID of each of words used in the text and a word occurrence count of a corresponding word. The word occurrence count indicates a number of occurrences of a word in each text. For each of words used in any of the texts constituting the text base, the system creates a total word occurrence count and a containing text count indicative of the number of texts containing the word. For each of words contained in the selected texts, a degree of importance is calculated by using the word occurrence count, the total word occurrence count and the containing text count. The words contained in the selected texts are sorted in order of the degree of importance. At least a part of the sorted words are displayed as related keywords.Type: GrantFiled: June 30, 1998Date of Patent: April 3, 2001Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Mitsuhiro Sato, Naohiko Noguchi, Yuji Kanno, Masako Nomoto, Mitsuaki Inaba, Yoshio Fukushige
