摘要： A document retrieval system for searching a document coinciding with a retrieval request the user inputs and further ranking the document in accordance with the degree of coincidence between the document and the retrieval request. In the document retrieval system, a word frequency calculating section finds out the number of documents where a word appears, a frequency of occurrence of the word in a document and obtains a weighting parameter for the word, and a frequency score calculating section obtains a frequency score on the basis of the output of the word frequency calculating section. In addition, a word cooccurrence relation checking section checks word cooccurrence relations of the retrieval request and the document, and a cooccurrence score calculating section calculates a cooccurrence score from the degree of coincidence therebetween. A document score calculating section calculates a document score on the basis of the frequency score and the cooccurrence score. The documents are ranked in order of document score and displayed to the user.

摘要： 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.
摘要翻译：一种用于提供关键字以便于在文本检索系统中进行搜索的系统。对于构成文本基础的每个文本，系统创建文本中使用的每个单词的单词ID和相应单词的单词出现计数。发生次数表示每个文本中出现的单词数。对于构成文本基础的任何文本中使用的每个单词，系统创建总词出现次数和包含指示包含单词的文本数量的文本计数。对于所选文本中包含的每个单词，通过使用单词出现次数，总词出现次数和包含的文本计数来计算重要程度。所选文本中包含的词根据重要程度的顺序排列。至少一部分排序的字词显示为相关关键字。

摘要： 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. The matching degree of combined field is calculated by logical operation between the two fields. Moreover, an index of combined field may be generated and one of field of the combined field may be omitted. The matching degree of the other field is also obtained by another logical operation.

摘要： A new type of text search apparatus, capable of finding all occurrence positions of a search string that is an arbitrary character string, within a text which is written as a continous sequence of characters, utilizes for text position reference purposes in an index file, words which each occur (at least once within the text) as the maximum length word, referred to as an extension word, among a set of arbitrarily predefined dictionary words extending from a specific character position. Each such occurrence of a word as an extension word defines one of a set of text position elements, with that set covering all of the character positions of the text. The index file also includes a table which relates each of the extension words to the respective positions at which each of the partial character strings of the word occur within the word. Each occurrence of an arbitrary search string within the text can thereby be expressed as either a partial character string within a single text position element, or as a sequence of partial character strings within a set of sequentially occurring text position elements, so that all such occurrences can be found by utilizing the index file.
摘要翻译：一种新型的文本搜索装置，能够在作为连续的字符序列写入的文本内发现作为任意字符串的搜索字符串的所有出现位置，用于索引文件中的文本位置参考目的，词语它们在从特定字符位置延伸的一组任意预定义的字典单元中发生（至少在文本内部）作为最大长度字，称为扩展字。作为扩展字的单词的每个这样的出现定义了一组文本位置元素中的一个，该集合覆盖文本的所有字符位置。索引文件还包括一个表，其将每个扩展词与单词中出现单词的每个部分字符串的各个位置相关联。因此，文本内的任意搜索字符串的每次出现由此可以表示为单个文本位置元素内的部分字符串，或者表示为在一组顺序发生的文本位置元素内的部分字符串的序列，使得所有这些事件可以通过使用索引文件找到。

摘要： Provided is a database management server apparatus that can maintain the consistency of updates and prevent blocking other update requests in an update process.A server apparatus 3 of a database management system 1 has a function of nondestructively updating databases in response to an update request from a client apparatus 2 to manage generation-management databases. A main storage unit 4 stores entities of a plurality of databases for each version of the databases, and a version creating unit 5 creates a new version of the databases in response to an update request from a client apparatus. A request accepting unit 11 accepts an update request for a next version regardless of whether the new version is being created. An acceptance management unit 13 starts a period for accepting the update request for the next version in response to the update request and ends the period for accepting after a predetermined time. A version creating unit 5 creates the next version based on the update request accepted in the period for accepting.

摘要： A rigidity checking method and apparatus is presented. A composite feature vector is first generated by combining three pairs of coordinates obtained for a feature point of a target object from three pictures of the target object. A covariance matrix of the compound feature vector is calculated by finding a product of a variance matrix comprising a variance of each element of the compound feature vector and the transposed matrix of the variance matrix. The rigidity of the target object is calculated by using the element of the covariance matrix and compared with a predetermined threshold to determine whether the target object is a rigid body. Thus, a rigidity checking is directly achieved from the joint distribution of feature points in the three pictures without assuming the coefficients of a set of constraint equations.
