We report on our work to automatically build a corpus of instructional text annotated with lexical semantics information. We have coupled the parser LCFLEX with a lexicon and ontology derived from two lexical resources, VerbNet for verbs and CoreLex for nouns. We discuss how we built our lexicon and ontology, and the parsing results we obtained.

We present the design and implementation of a probabilistic, nondeterministic programming language called Invocat for defining and generating from context-free grammars. We define Invocat’s lexical, concrete, and abstract syntaxes as well as its operational semantics. We implement the language in Lua as a lexical analyzer, parser, and interpreter.

Normalization and lexical annotation methods, developed in the context of matching systems, have proven to be effective for the discovery of lexical relationships among schemata. We will show how these methods are applicable and effective in the context of Semantic Resource Framework to mine the semantics of a web service interface and to discover mappings between them.

The domain of linguistics that has probably been studied most with corpora is lexical semantics. The main assumption underlying nearly all corpus-based work in lexical (and constructional) semantics is that the distributional characteristics of a linguistic expression reveal many if not most of its semantic and functional properties. The maybe most widely-cited statement to this effect is Firth...

We report work in progress on measuring “forces” underlying the semantic drift by comparing it with plate tectonics in geology. Based on a brief survey of energy as a key concept in machine learning, and the Aristotelian concept of potentiality vs. actuality allowing for the study of energy and dynamics in language, we propose a field approach to lexical analysis. Until evidence to the contrary...

This paper is concerned with the ability of lexical semantic classes to predict the behavior of argument structures in productively selecting novel lexical material. It will be argued that while lexical semantic classes can explain a great deal about the spectrum of potential arguments and resulting entailments for those arguments, constructions which are synonymous from a formal semantic persp...

Recently, two operable WSDL retrieval approaches, bipartite-graph matching and KbSM, were developed for Web service discovery. But their models and similarity metrics of WSDL ignore some term or semantic feature, and involve formal method problem of representation or difficulty of parameter verification. SLVM approaches depend on statistical term measures to implement XML document representatio...
