Adaptive Temporal Query Modeling

Free registration required

Executive Summary

The authors present an approach to query modeling that uses the temporal distribution of documents in an initially retrieved set of documents. Such distributions tend to exhibit bursts, especially in news-related document collections. They hypothesize that documents in those bursts are more likely to be relevant and update the query model with the most distinguishing terms in high-quality documents sampled from bursts. They evaluate the effectiveness of their models on a test collection of blog posts.
