<p>Effective information customization systems must adjust their behavior to the user's task context. WordSieve, a text analysis algorithm, generates representations of users' topics of interest based on their browsing patterns. By finding terms associated with sequences of related documents, WordSieve learns topic-relevant keywords in real time with no predetermined corpus. You can use these keywords to form search engine queries to suggest relevant documents to the user. This article sketches the project goals, the WordSieve algorithm, and encouraging experimental results comparing WordSieve to TFIDF (term frequency inverse document frequency) and LSI (latent semantic indexing) at a precision-recall task.</p>
