... new generative model, the entity-mention model, which can leverage heterogenous entity knowledge (including popularity knowledge, name knowledge and context knowledge) for the entity linking ... 946 2 The Generative Entity-Mention Model for Entity Linking In this section we describe the generative entity- mention model. We first describe the generative sto...

The model used sentiment ... only 8 relevant documents without any opinion and 14 documents with relevant opinions. As a result, the graph constructed by insufficient documents worked ineffectively.

Because there are an exponential number of summaries that can be generated for any given ... memory for longer documents; therefore, we se- lected shorter subtexts from the original documents. We used both the WSJ and Mitre data for eval- uation because we wanted to see whether th...
