HLTCOE Submission at TREC 2013: Temporal Summarization

Our team submitted runs for the first running of the TREC Temporal Summarization track. We focused on the Sequential Update Summarization task. This task involves simulating processing a temporally ordered stream of over 1 billion documents to identify sentences that are relevant to a specific breaking news stories which contain new content. In this paper, we describe our approach and evaluation results.
