Abstract: 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.

Abstract: According to an embodiment, a structured document management apparatus includes a document storage unit, a section title extracting unit, a relevance calculator, a document search unit, a section title selector, and a section title display controller. The section title extracting unit extracts the section titles from the structured document to create a section title list.
