STRUCTURED TEXT SEARCH-EXPRESSION-GENERATING DEVICE, METHOD AND PROCESS THEREFOR, STRUCTURED TEXT SEARCH DEVICE, AND METHOD AND PROCESS THEREFOR

摘要

Provided is a structured document search formula generating device capable of generating a search formula, which searches for a target element by automatically specifying an element acting as a guideline as a search condition when the element acting as the guideline is not structurally present on a structural related position but the element acting as the guideline is present on a display screen. The structured document search formula generating device is provided with a sample text accumulating unit, which accumulates a plurality of sample texts each composed of a structured document being a search target for each document type, an element specifying unit, which specifies a search target element in each of a plurality of sample texts, a structure analyzing unit, which analyzes a structure of a specified sample text and generates a search formula indicating a structural position of the specified search target element in a structure of the sample text, a screen analyzing unit, which analyzes a display image of the specified sample text and determines the element present on a common relative position on the display image of each of a plurality of sample texts as a guideline element on a screen, and a search formula combining unit, which generates one obtained by adding the determined guideline element on the screen as a condition to the search formula indicating the generated structural position.
