	abstract = {This article examines the use of LSA (latent semantic analysis) to evaluate student summaries. The authors argue that summary is a key component of student learning, and that summary writing and LSA share certain similarities that may make them compatible for evaluation. In the study outlined in this article, 786 students were required to write 50 word summaries of either a narrative or expository piece of writing. Then human evaluators and the LSA equation were used to mark the effectiveness of the summary. The results showed that LSA held a 0.68 reliability for the narrative summaries and a 0.82 reliability for the expository summaries. Given these results, the authors concluded that it was too early to determine whether LSA was effective in evaluating student summaries. },
