Abstract: To solve the problem of the lack of summarization method of experts' speeches in CWME, a new method was proposed. This method first adopts a probabilistic mixture model to discover latent themes from experts’speeches.Then, it judges whether themes have changed. Once they are changed, this method will generate summary and provide it for experts. The summaries can help experts to inspire each other in CWME. Experimental result shows that the proposed method is feasible and effective.
