摘要

Provided is a search expression creating system enabling creation of a search expression by showing an example even if the interpretation by a structure analysis means used for showing an example is different from that by a structure analysis means used for search and creation of a search expression for a plurality of structure analysis means which give different interpretations from each other.The search expression creating system includes an identifier giving means for adding an identifier to an element of a structured document as an attribute independent of structure analysis, a search element specifying means for analyzing the structured document to which the identifier is added, receiving an input of the search target element from the user, and obtaining the identifier added to the inputted search target element, and a search expression creating means for analyzing the structured document to which the identifier is added, receiving an input of the identifier corresponding to the search target element from the search element specifying means, searching the analyzed structure for the search target element by using the inputted identifier, and creating a search expression indicating the position of the search target element in the structure.
