1. A search expression generation device comprising:
an input/output device; an arithmetic operation control device; a storage device; a model sentence accumulation unit which accumulates a plurality of model sentences of structured documents to be searched in the storage device on a kind basis by said arithmetic operation control device; an element designation unit which designates an element to be searched in a plurality of model sentences, wherein the input/output device is configured to allow a user to control the element designation unit to specify the element to be searched; a structured document analysis unit which analyzes, by said arithmetic operation control device, a structure of said model sentence designated to select an element to be added to a search expression as a condition, and an element to be deleted from the search expression as a condition based on said element designated to be searched; and a search expression structuring unit which adds or deletes said element selected to or from a search expression by said arithmetic operation control device, wherein:
said structured document analysis unit analyzes a structure of a model sentence designated by said element designation unit to generate a search expression with a condition added which is common to a plurality of model sentences of the same kind,the arithmetic operation control device is implemented via a CPU; andsaid structured document analysis unit sequentially obtains a parent element of said element to be searched and an element position, and with respect to a first model sentence, generates a main search expression formed of elements to be traced back to said element to be searched from a top element and with respect to a model sentence after the first sentence, compares the element with an element of said main search expression generated and eases a condition of said main search expression with respect to a part failing to coincide. |
