Document processing device, document processing method, and storage medium recording program therefor

Abstract

A document processing device, a document processing method, and a storage medium recording program therefor. The invention provides a document processing device including: a memory that stores syntax data expressing syntax of character strings whose probability of being a title of a document is high or-character strings whose probability of being a title of a document is low; an input unit that inputs document data obtained by digitizing a document; an extraction unit that analyzes the input document data and extracts character string data expressing character strings; a syntax analyzing unit that analyzes the extracted character string data and specifies the syntax of each character string contained in the document corresponding to the document data; and a specifying unit that specifies, from among the extracted character string data, character string data expressing a title of the document corresponding to the document data, based on results of specification by the syntax analyzing unit and content stored in the memory.

Description

technical field [0001] The present invention relates to a technique for digitizing a paper document, and in particular, a technique for specifying a title according to the content of a paper document. Background technique [0002] Paper documents (hereinafter also referred to as "documents") are excellent media for transferring and recording information, but necessarily come with problems including the need for storage space such as archives. In addition, when information is recorded in paper documents and saved, if information recorded in these paper documents is required later, it is necessary to find among a large number of paper documents kept in archives and the like in which desired information is recorded paper documents. In other words, recording and saving information in paper documents is not ideal from the standpoint of operational efficiency. [0003] In such cases, paper documents are usually digitized and stored. Specifically, images corresponding to each pa...

Problems solved by technology

[0005] However, the techniques disclosed above have the problem that the title of the document is based on the presence or absence of formatting (such as underscores) that is irrelevant to the meaningful content of the character strings contained in the paper document to be digitized, or based on the presence or absence of other character strings. specified distances, which is prone to judgment errors, which makes it impossible to achieve a specified level of accuracy high enough to be practicable
