An electronic document repository system comprises a storage arrangement 30-36 for storing a plurality of electronic documents; tagging means 132 for permitting users of the repository to apply tags to the documents; automatic tag processing means 134 for generating a lattice representation and assigning stored documents to nodes of the lattice representation based upon the tags applied to the documents; wherein, the repository further comprises a lattice representation difference determiner 138 which is operable to compare two lattice representations of the type generated by the automatic tag processing means 134 and to generate a difference value indicating an extent by which the compared lattice representations differ from one another according to an edit distance measure. |
