摘要：

Evaluation is one of the hardest tasks in automatic text summarization. It is perhaps even harder to determine how much a particular component of a summarization system contributes to the success of the whole system. We examine how to evaluate the sentence ranking component using a corpus which has been partially labelled with Summary Content Units. To demonstrate this technique, we apply it to the evaluation of a new sentence-ranking system which uses Roget's Thesaurus. This corpus provides a quick and nearly automatic method of evaluating the quality of sentence ranking.
