... present paper. 4. SEMANTICS FOR QLF In this section we outline the semantics of the QLF language in a way that is as close as possible to classical approaches that provide the semantics in terms ... monotonic interpretation and categorial semantics part company is on the degree of ex- plicitness with which semantic derivations are rep- resented. In categorial semantics, derivation...

Pantel (2005) defined the task of ontologizing a lexical semantic resource as linking ... complex lexi- cal structures like binary semantic relations, the paper focused only on attaching terms.

... empirically that correct interpreta- tions tend to form semantic classes, and therefore, correct interpretations should be related to each other by semantic relations, such as synonymy or hyponymy. ... Lascarides compiled their test set by selecting 12 verbs that allow logical metonymy 1 from the lexical semantics literature and combin- ing each of them with 5 nouns. This yields 60 phrase...

We propose an integrated distributional similarity filter to identify and censor potential semantic drifts, ... 10% higher precision when ex- tracting large semantic lexicons. 1 Introduction Iterative bootstrapping algorithms have been pro- posed to extract semantic lexicons for NLP tasks with l...
