[0032] figure 1 The overall configuration of the document search device according to the first embodiment of the present invention is shown.

[0033] The document search device of this embodiment includes an input unit 11 , a document search unit 12 , an output unit 15 , a document storage unit 16 , a document structure storage unit 17 , an extracted sentence storage unit 18 , and a method determination rule storage unit 19 .

[0034] The input unit 11 inputs a character string as a search request. That is, the character string input by the user using the input unit 11 is sent to the document search unit 12 as a search request, and the document search is performed. The input unit 11 is, for example, a keyboard and a mouse, and is used for user's input and instruction. Specifically, the input character string entered by the user through the keyboard is displayed on the input screen displayed on the monitor, and the "send" button on the input screen is clicked with the mouse a...

[0086] Figure 11 This is a schematic configuration of a document search device according to a second embodiment of the present invention. In addition, the same code|symbol is attached|subjected to the same structure as 1st Embodiment, and description is abbreviate|omitted.

[0087] Such as Figure 11 As shown, the structure of the file retrieval device in this embodiment is as follows: figure 1 The structure of the document retrieval device shown further includes a retrieval method specifying unit 20 .

[0088] The user specifies a search method in favor of the search method specifying unit 20 . Based on the search method specified by the search method specifying unit 20 , the document search unit 12 searches the document storage unit 16 again.

[0089] refer to Figure 12 An example of the search method specifying process by the search method specifying unit 20 will be described. Figure 12 The search screen 110 shown shows a state where the user enters the character s...

[0095] Figure 14 A schematic configuration of a document search device according to a third embodiment of the present invention is shown. In addition, the same code|symbol is attached|subjected to the same structure as 1st Embodiment, and description is abbreviate|omitted.

[0096] Such as Figure 14 As shown, the structure of the file retrieval device in this embodiment is as follows: figure 1 In the configuration of the shown document retrieval device, a query candidate generation unit 27 and a query selection unit 28 are further included.

[0097]The query candidate generating unit 27 generates search query candidates (hereinafter referred to as query candidates) corresponding to the user's input character string. That is, the query candidate generation unit 27 compares the input character string input from the input unit 11 with the token 302 or the pronunciation 303 of the extracted sentence stored in the extracted sentence storage unit 18 . As a result of the compar...

Abstract

A document searching system of an embodiment comprises a storage device storing structured document data, extracted phrase information of phrases in the structured document data which includes an identifier of the extraction-source structured document data containing each of the phrases and includes an attribute of each of the phrases in the extraction-source structured document data, and a mode determination rule including a search mode and a display format for each attribute. The document searching system of this embodiment inputs a search phrase, determines an attribute of the search phrase with reference to the extracted phrase information if the extracted phrase information contains a phrase matching the search phrase, determines a search mode for searching the structured document data and a display format of a search result with reference to the mode determination rule based on the determined attribute.

Description

[0001] This application claims priority from a prior Japanese Patent Application No. 2011-003439 filed on January 11, 2011, and uses the entire contents thereof. technical field [0002] The invention relates to a file retrieval device and a file retrieval method. Background technique [0003] With the digitization of documents and the popularization of the World Wide Web (WWW), document retrieval is widely used in daily life and various businesses. For example, by using search services on the Internet, users can collect information recorded on global web pages just by inputting keywords. In addition, document search is used not only in search services on the Internet, but also in systems for document management and information sharing in companies and government agencies, and tools for organizing personal information. [0004] Document retrieval is performed by inputting a retrieval request such as a keyword. As the output result of the file search, for example, a list of...
