This paper investigates the use of a hybrid language model for open-vocabulary Thai LVCSR. Thai text is written without word boundary markers and the definition of word unit is often ambiguous due to the presence of compound words. Hence, to build open-vocabulary LVCSR, a very large lexicon is required to also handle word unit ambiguity. Pseudomorpheme (PM), a syllable-like sub-word unit specif...

This paper investigates the variation of resultative serial verb constructions in Benue-Kwa languages. The main claim is that can be explained assuming three versions general lexicon rules which turn verbs into complex predicates selecting for a second and attracting its arguments. Each language has specific version these rules, enriched with peculiarities to account behaviour verbal inflection...

It is known that POS tagging is not very accurate for unknown words (words which the POS tagger has not seen in the training corpora). Thus, a first step to improve the tagging accuracy would be to extend the coverage of the tagger’s learned lexicon. It turns out that, through the use of a simple procedure, one can extend this lexicon without using additional, hard to obtain, hand-validated tra...

1 Cross-disciplinary Issues in Lexical Theories It is hardly a controversial statement that the acquisition and processing of language require knowledge of its words. Yet, the type and use of information encoded in a lexical entry, the relation of words to each other in the lexicon, and the relationship of the lexicon to the grammar, are complex and unsettled issues, on which researchers hold v...

The growth of web 2.0 application, consumer feedback about product is analyzed to improve the quality of the product. The consumer feedback or reviews are extracted from the social media and then determine the polarity (positive, negative or objective) is called sentiment analysis. It is also known as opinion mining or appraisal extraction or review mining. The sentiment lexicon plays an import...

A lexicon is a list of words in a language—a vocabulary—along with some knowledge of how each word is used. A lexicon may be general or domain-specific; we might have, for example, a lexicon of several thousand common words of English or German, or a lexicon of the technical terms of dentistry in some language. The words that are of interest are usually open-class or content words, such as noun...

A long-standing debate in the computational linguistic communi ty is about the generality of lexical taxonomies. Many linguists (Nirenburg 1995; Hirst 1995) stress that taxonomies that are not language neutral, at least at the intermediate and high level, have little hope of success. On the other hand, lexicon builders who have experience of designing taxonomies for real applications claim that...

C reating a common language provides one of a social enter-prise's defining moments, be it a technical, scientific, or humanistic venture. The lan-guage's most obvious utility derives from its allowing a field's participants to communicate among themselves. Its importance extends beyond this function , however. More than a neutral medium through which we exchange information , language serves t...

This paper describes a set of interactive routines that can be used to create, maintain, and update a computer lexicon. The routines are available to the user as a set of commands resembling a simple operating system. The lexicon produced by this system is based on lexical-semantic relations, but is compatible with a variety of other models of lexicon structure. The lexicon builder is suitable ...

How many words are needed to define all the words in a dictionary? Graph-theoretic analysis reveals that about 10% of a dictionary is a unique Kernel of words that define one another and all the rest, but this is not the smallest such subset. The Kernel consists of one huge strongly connected component (SCC), about half its size, the Core, surrounded by many small SCCs, the Satellites. Core wor...
