... relevance of hierarchical topic models to represent the content of Web gists. We focus our attention on DMOZ, a popular Web directory, and propose two algorithms to infer such a model from its manually-curated ... content model, but a selection of highly salient vocabulary for every cat- egory of the hierarchy. The problem considered in this paper is connected to the area of...

... of prosodic phrasing and tone scaling in standard, i.e. Tokyo, Japanese. The possibility of equating syntactic and prosodic structure in this way follows from a view of syntax with two characteristics. ... elements of the syntactic model used in the analysis of Japanese are presented. We then approach the syntax-prosody interface from the opposite end, and lo...
