This report describes a query expansion method based on the expansion of geographical terms by means of WordNet synonyms and meronyms. We used this method for our participation to the GeoCLEF 2005 English monolingual task, while using the well-known Lucene search engine for indexing and retrieval. The obtained results show that the proposed method was not suitable for the GeoCLEF track, while W...

In recent times, wordnets have become indispensable resources for Natural Language Processing. However, the creation of wordnets is a time consuming and manpower intensive proposition. This fact has led to attempts at quickly fixing a wordnet using text repositories such as the web and certain corpora, and also by translating an existing wordnet into another language. However, the results of su...

The nouns “element” and “radical” are prominent words in the chemist’s vocabulary. That their meanings nowadays are radically different is a fact that is elementary to all, yet, given their prominence, it is striking that a millennium ago they were virtually synonyms. By the late eighteenth century, Lavoisier and his colleagues had assigned them different denotations. Given the fundamental stat...

Rating a page to be a best one, based only on Page Ranking algorithm of Brin and Page would be insufficient. This method relied totally on Link information alone. However, due to application of Soft Computing in Data Mining and Knowledge Discovery, machines were made more effective, additional features of a Page involving its indexing, terms used, capitalizations, anchor texts, hit information,...

Multigrid (MG) methods are used to approximate solutions to elliptic partial differential equations (PDEs) by iteratively improving the solution through a sequence of coarser discretizations or grids. The methodology has been developed and extended since the 1970’s to also target more general PDEs and systems of algebraic equations. A typical approach consists of a series of refinements or grid...

This paper presents a method for acquiring synonyms from monolingual comparable text (MCT). MCT denotes a set of monolingual texts whose contents are similar and can be obtained automatically. Our acquisition method takes advantage of a characteristic of MCT that included words and their relations are confined. Our method uses contextual information of surrounding one word on each side of the t...

Abstract How much information do language users need to differentiate potentially absolute synonyms into near-synonyms? consistent must the be? We present two simple experiments designed investigate this. After exposure novel verbs, participants generalized them positive or negative contexts. In Experiment 1, there was a tendency across conditions for verbs become differentiated by context, eve...
