摘要： A document searching apparatus includes an input unit that inputs a search query for conducting a search in a structured document, the structured document being obtained by expressing elements included in a document in a hierarchical manner; a query converting unit that converts a query sentence constituting the search query and a search target element of the query sentence according to a predetermined rule so as to generate a new search query; a document searching unit that searches the structured document by using the new search query; and a search-result presenting unit that presents a result of the search.

摘要： According to one embodiment, a keyword presentation apparatus includes an extraction unit, a selection unit and a clustering unit. The extraction unit is configured to extract, as technical terms, morpheme strings, which are not defined in a general concept dictionary, from a document set. The selection unit is configured to evaluate relevancies between each of basic term candidates and the technical terms, and to preferentially select basic term candidates having high relevancies as basic terms. The clustering unit is configured to calculate weighted sums of statistical degrees of correlation between the basic terms based on the document set, to calculate conceptual degrees of correlation between the basic terms based on the general concept dictionary, and to cluster the basic terms based on the weighted sums.

摘要翻译： 根据一个实施例，关键词呈现装置包括提取单元，选择单元和聚类单元。 提取单元被配置为从文档集合中提取未在通用概念字典中定义的语素字符串作为技术术语。 选择单元被配置为评估每个基本术语候选者和技术术语之间的相关性，并优先选择具有高相关性的基本术语候选者作为基本术语。 聚类单元被配置为基于文档集来计算基本项之间的统计学相关度的加权和，以基于一般概念词典计算基本术语之间的概念相关度，并且基于 加权总和。

摘要： An apparatus for retrieving structured documents includes a first categorizing unit configured to categorize components into a first component of typical descriptions and a second component of atypical descriptions, based on statistics information for the components, a second categorizing unit configured to categorize the terms into a first term whose appearance ratio in the first component exceeds a threshold and a second term whose appearance ratio in the first component is not more than the threshold, an extraction unit configured to extract a set of structured documents each having the first component including the first term and the second component from the structured documents, and a ranking unit configured to rank the set of structured documents by a retrieval score calculating based o a relation between the second term and the second component.
