This document summarizes preliminary results from measuring similarity between folksonomies and LSA. It crawled over 7.5 million tags from Delicious and processed them to create tag vectors for measuring co-occurrence counts and cosine similarity between tags. It also created an LSA corpus from over 17,000 web pages to generate a term-document matrix. The document analyzes correlations between different similarity measures and provides examples of related tags for the term "linguistics".
