This paper describes the HKPolyU-HKUST systems which were entered into the Semantic Role Labeling task in Senseval-3. Results show that these systems, which are based upon common machine learning algorithms, all manage to achieve good performances on the non-restricted Semantic Role Labeling task.
Coreference resolution is the process of determining the entity that noun phrases refer to. A great deal of research has been done on this task in English, using approaches ranging from those based on linguistics to those based on machine learning. In Chinese, however, much less work has been done in this area. One reason for this is the lack of resources… (More)
Coreference resolution is the process of identifying expressions that refer to the same entity. This paper presents a clustering algorithm for unsupervised Chinese coreference resolution. We investigate why Chinese coreference is hard and demonstrate that techniques used in coreference resolution for English can be extended to Chinese. The proposed system… (More)
