Summary

Query expansion was found to be very useful for microblog retrieval, while affinity propagation achieved comparable performance when combined with other techniques. The approach involved building separate indexes for different queries, using techniques such as exploring tags and N-gram to reformulate queries, and applying the relevance feedback model for query expansion. Affinity propagation was used to cluster tweets and update their scores based on their similarity to relevant tweets. The algorithm was found to be easy to implement and fast in practice, and the final score of a tweet was based on its relevance score and the relevance score of its representative in the group.
