There is a general concern within the field of word sense dusamb~guatmn about the rater-annotator agreement between human annotators. In thus pa- per, we examine th~s msue by comparing the agree- ment rate on a large corpus of more than 30,000 sense-tagged instances Thin corpus us the mtersec- tmn of the WORDNET Semcor corpus and the DSO corpus, which has been independently tagged by two separate groups of human annotators The contri- bution of this paper us two-fold First, ~t presents a greedy search algorithm that can automatically de- rive coarser sense classes based on the sense tags assigned by two human ...
on a variety of word types and ambiguities. A rich variety of techniques have been researched, from dictionary-based methods that use the knowledge encoded in lexical resources, to supervised machine learning methods in which a classifier is trained for each distinct word on a corpus of manually sense-annotated examples, to completely unsupervised methods that cluster occurrences of words, thereby inducing word senses. Among these, supervised learning approaches have been the most successful algorithms to date. Current accuracy is difficult to state without a host of caveats. On English, accuracy at the coarse-grained ( homograph

As we all are aware that there are only two ways one can use for communication first is [censored] and the second one is written. Natural Language processing is the area where we deal with both the approach of communication. For [censored], natural language processing support the area called as "Speech Processing". In the same line to handle written communication NLP supports the area known as "Text Processing". This paper focuses the second version of communication where we communicate using any language by writing some thing. In this paper we have given a proposed methodology, by which we can describes the ... market research, surveys and trends

Craftsbury Rowers Compete at U23 World Championships
Seven Craftsbury Small Boat Training Center (SBTC) rowers represented the United States at the U23 World Championships last weekend, with results that were historic for both the SBTC program and United States rowing in general. The program, which is only in its second year of existence, provides college rowers competing in singles, pairs, and doubles with coaching and training opportunities at the Craftsbury Outdoor Center in Craftsbury Common, Vermont. Elizabeth and Rebecca Donald, who are entering their senior year at the University of Pennsylvania this spring, brought home the first U23 medal in SBTC history, rowing to third ... market trends, news research and surveys resources

Genetic algorithm at AllExperts
to an optimization problem evolves toward better solutions. Traditionally, solutions are represented in binary as strings of 0s and 1s, but different encodings are also possible. The evolution starts from a population of completely random individuals and happens in generations. In each generation, the fitness of the whole population is evaluated, multiple individuals are stochastically selected from the current population (based on their fitness), and modified (mutated or recombined) to form a new population. The new population is then used in the next iteration of the algorithm. A typical genetic algorithm requires two things ...
Phrase Based Multiple Indexing and Keyword Co-Occurrence
Using a timeline as a starting point, in November, 2003 there was a quiet introduction of Google's use of stemming, whereas before they had stated that they didn't use it. That was also the month of the Florida Debacle, the update that shook up the SERPs, and talk about LSI/Latent Semantic Indexing started. In short, according to what I've read LSI isn't feasible for a large scale search engine because first off, as such it's a patented technology, and secondly it's very resource intensive. LSI also uses single words - terms. However, 8 months later there was a series of patent applications filed by ...
