Phrase Discovery for English and Cross-language Retrieval at TREC 6

In our TREC 6 experiments for the main tasks and tracks, Berkeley worked primarily on extending our probabilistic document retrieval methods to incorporate two words phrases found using the ranking provided by expected mutual information measure. While these methods did not result in performance improvements for English retrieval, they were central in obtaining reasonable performance in English queries against German documents in the crosslingual track
