Abstract: We present a pseudo relevance feedback technique for information retrieval, which expands keyword queries with semantic annotation found in the freely available collaborative tagging system. We hypothesise that collaborative tags represent semantic information
that may render queries more informative, and hence enhance retrieval performance. Experiments with three different techniques of enriching queries with tags, and also varying the number of tags used for expansion between 1-10, show only a small improvement in retrieval precision, over a baseline of short keyword queries.
