... semantic score accounts for the semantic preference on a given set of lexical categories and a particular syntactic structure for the sentence. Various formulation for the lexical score and ... abilities for different syntax trees, an alternative formulation of the syntactic score is to evaluate the transition probabilities between configuration changes of the parser. For...

... therefore, we create an in- dividual model for every (ambiguous) word rather than a global model for an entire document col- lection. We also show how multiple information sources can be straightforwardly ... in LDA-related models (Grif- fiths and Steyvers, 2002). For simplicity, we used uniform weights for the layers. The Gibbs sampler was run for 2,000 iterations. Due to the random...
