As with most computer science problems, representation of the data is the key to ecient and eective solutions. Piecewise linear representation has been used for the representation of the data. This representation has been used by various researchers to support clustering, classication, indexing and association rule mining of time series data. A variety of algorithms have been proposed to obtain...

We describe a computational framework for a grammar architecture in which different linguistic domains such as morphology, syntax, and semantics are treated not as separate components but compositional domains. Word and phrase formation are modeled as uniform processes contributing to the derivation of the semantic form. The morpheme, as well as the lexeme, has lexical representation in the for...

While there has been considerable research on both structural annotation (such as the Penn Treebank (Taylor et al., 2003) or the Kyoto Corpus (Kurohashi and Nagao, 2003)) and semantic annotation (e.g. Senseval: Kilgariff and Rosenzweig, 2000; Shirai, 2002), there are almost no corpora that combine both. This makes it difficult to carry out research on the interaction between syntax and semantic...

This work tries to align the knowledge representation of Anatomy with Galen modelling of the French new coding system of surgical procedures named CCAM and the UMLS semantic network. We use a mixed method lexical and semantic to align the semantic categories of Galen CCAM with the UMLS semantic types. The matching rate is high and the 22 % of non matched Galen CCAM descriptors are depending upo...

Semantic inference is an important component in many natural language understanding applications. Classical approaches to semantic inference rely on logical representations for meaning, which may be viewed as being “external” to the natural language itself. However, practical applications usually adopt shallower lexical or lexical-syntactic representations, which correspond closely to language ...

In this paper wc examine a subset of polyscmous elements, the logical structure of nominals, and argue that maw cases of polysemy have well-defined calculi, which interact with the grmnmar in predictable and determinate ways for disambiguation. These calculi constitute part of the lexicai organization of the grammar and contribute to the lexical semantics of a word. The lexieal system of the gr...

This study will consider the semantic behavior of the temporal negators not yet and never in English. In this paper, I show that not yet, by default, uses the stereotypical intervals connected with certain events to determine the time span of its negation, while never systematically ignores these stereotypical intervals. I show that in order to correctly distinguish between these two lexical it...
