How to Study and Master Polysemants in Ancient Chinese Prose
Vocabulary learning is the Key point as well as the difficult point in ancient Chinese Prose Study,meanwhile,the overwhelming majority of them are polysemys.In the concrete,there are several as-pects should be considered.The first is to know the systematicness of vocabulary and to master the inter-nal relations among the polysemants,especially,the rules of the extended meaning which are the key points to know the polysemous system.The second is to notice the speech environment.
We focus on the problem of learning semantics from multimedia data associated with broadcast video documents. In this paper we propose to learn semantic concepts from multimodal sources based on style and context detectors, in combination with statistical classier ensembles. As a case study we present our method for detecting the concept of news subject monologues. This approach had the best average precision performance amongst 26 submissions in the 2003 video track of the Text Retrieval Conference benchmark. Experiments were conducted with respect to individual detector contribution, ensemble size, and ranking mechanism. It was found that the combination of detectors is decisive for the nal result, although some detectors might appear useless in isolation. Moreover, by using a probabilistic ranking, in combination with a large classier ensemble, results can be improved even further.
