Abstract: A computer-implemented method for obtaining the rendering co-ordinates of visible text elements on a web page is disclosed. The web page is represented by an input data structure comprising a plurality of text nodes, each of which represents a text element on the web page. The method comprises the following steps: a) using a computer device, wrapping each of the plurality of text nodes in a pair of mark-up language tags; b) using said computer device, obtaining the co-ordinates of a bounding rectangle for each text node using the mark-up language tags; c) using said computer device, attaching an attribute specifying the co-ordinates of the bounding rectangle to each text node; and d) using said computer device, determining whether each text node is invisible, and if it is, excluding it from an output data structure comprising the plurality of text nodes and attached attributes.

Abstract: Disclosed is a method and apparatus for searching electronic documents. The 5 apparatus comprises first and second data repositories storing tags for representing content of an electronic document. The first data repository is adapted to store structured tags and their respective association with an electronic document, a structured tag comprising information representing its relationship to at least one other tag. The second data repository is adapted to 10 store free tags and their respective association with an electronic document, a free tag not comprising information representing its relationship to any other tags. Electronic documents can be searched by accessing the first and second data repositories, and matching a search query with one or more tags in the first and second data repositories. For each matched tag, an electronic document 15 associated with the tag can then be retrieved and a ranking for the electronic document determined based on attributes of the document and its associated tag.
