The invention relates to a method and apparatus for optimising the searching of tagged files, and in particular a method and apparatus for optimising the searching of files tagged by a community of users where the inter-relationships between tagged files and the specific user tagging the files within a group are taken into account in the optimisation. A store of files, tagged with various keywords, is searched using a query term provided by a user. The search results are ranked using a weighted tag network based on co-authorship of tags with weighted inter-dependencies based on degree of associations between keywords. The weighted tag network is generated based on tags created by users of a common group or community, and hence the resulting ranking of search results reflects the user group. Furthermore, the query term used for searching can also be expanded using the tag network to give additional potentially useful terms for searching the files with. |
