Over the last few years there has been increased research in automated question-answering from text, including questions whose answer is implied, rather than explicitly stated, in the text. WordNet has played a central role in many such systems (e.g., 21 of the 26 teams in the recent PASCAL RTE3 challenge used WordNet), and thus WordNet is being increasingly stretched to play more semantic task...

We discuss the development of a multilingual lexicon linked to a formal ontology. First we describe the Open Multilingual Wordnet, a multilingual wordnet with twenty two languages and a rich structure of semantic relations. It is made by exploiting links from various monolingual wordnets to the English Wordnet. Currently, it contains 118,337 concepts expressed in 1,643,260 senses in 22 language...

In this paper, an automatic method for Persian WordNet construction based on Prenceton WordNet 2.1 (PWN) is introduced. The proposed approach uses Persian and English corpora as well as a bilingual dictionary in order to make a mapping between PWN synsets and Persian words. Our method calculates a score for each candidate synset of a given Persian word and for each of its translation, it select...

In this paper, we report our methods and results of using, for the first time, semi-automatic approach to enhance an Indian language Wordnet. We apply our methods to enhancing an already existing Sanskrit Wordnet created from Hindi Wordnet (which is created from Princeton Wordnet) using expansion approach. We base our experiment on an existing bilingual Sanskrit English Dictionary and show how ...

The NLP research group at the University of Szeged took part in the development of the Hungarian WordNet between 2005 and 2007. In 2008, they developed a smaller, domain specific WordNet on customs law. This knowledge base contains about 650 concepts cautiously selected by legal experts from the relevant Hungarian statutory legal texts, above all, from two acts and from other laws and decrees. ...

This paper describes automatic construction a freely-available wordnet for French (WOLF) based on Princeton WordNet (PWN) by using various multilingual resources. Polysemous words were dealt with an approach in which a parallel corpus for five languages was word-aligned and the extracted multilingual lexicon was disambiguated with the existing wordnets for these languages. On the other hand, a ...

This paper presents an automatic method and interface to enrich semantically WordNet 1.6. with categories or classes from other classification systems. In order to build the WordNet enriched it is necessary the creation of a interface to label WordNet with categories from different available classification systems. We also describe features of the design and implementation of the interface to o...

1. Introducción El objetivo del experimento presentado en este trabajo es la expansión del WordNet gallego mediante extracción léxica a partir de un diccionario de sinónimos de esta lengua. El experimento se realiza dentro del proyecto coordinado SKATeR en el que nuestro grupo tiene como objetivo prioritario la construcción de Galnet, la versión gallega del WordNet 3.0. El marco de desarrollo e...

In this paper, we propose a method of MultiObjective Genetic Algorithms (MOGAs), NSGA-II and SPEA2, for document clustering with semantic similarity measures based on WordNet. The MOGAs showed a high performance compared to other clustering algorithms. The main problem in the application of MOGAs for document clustering in the Vector Space Model (VSM) is that it ignores relationships between im...

This paper describes the construction of a linguistic knowledge base using Frame Semantics, instantiated with Chinese Verbs imported from the Chinese-English Bilingual Ontological WordNet (BOW). The goal is to use this knowledge base to assist with semantic role labeling. This is accomplished through the mapping of FrameNet and WordNet and a novel verb selection restriction using both the WordN...
