Abstract

To obtain a query for use in information retrieval, a document is scanned. The resulting text image data define an image of a segment of text in a first language. Automatic recognition is then performed on at least part of the text image data to obtain text code data including a series of element codes. Each element code indicates an element that occurs in the first language, and the series of element codes defines a set of expressions that also occur in the first language. Automatic translation is then performed on a version of the text code data to obtain translation data indicating a set of counterpart expressions in a second language. The counterpart expressions are used to automatically obtain query data defining the query. The query can then be provided to an information retrieval engine.
