Some Issues with Building a Multilingual Wordnet

2016

This paper introduces the motivation for and design of the Collaborative InterLingual Index (CILI). It is designed to make possible coordination between multiple loosely coupled wordnet projects. The structure of the CILI is based on the Interlingual index first proposed in the EuroWordNet project with several pragmatic extensions: an explicit open license, definitions in English and links to wordnets in the Global Wordnet Grid.

The Global Wordnet Formats have been introduced to enable wordnets to have a common representation that can be integrated through the Global WordNet Grid. As a result of their adoption, a number of shortcomings of the format were identified, and in this paper we describe the extensions to the formats that address these issues. These include: ordering of senses, dependencies between wordnets, pronunciation, syntactic modelling, relations, sense keys, metadata and RDF support. Furthermore, we provide some perspectives on how these changes help in the integration of wordnets.

This paper describes the multilingual design of the EuroWordNet database. The EuroWordNet database stores wordnets as autonomous language -specific structures that are interconnected via an Inter-Lingual-Index (ILI). In this paper, we discuss the possibilities to create mappings from each wordnet to the central ILI and how the ILI itself can be adapted to provide more overlap across the wordnets. We will argue that the ILI can be condensed to a more universal index of meaning, while the wordnets can still encode any fine-grained lexicalizations for each language.

The paper reports on the ongoing effort towards the development of a Romanian wordnet aligned to the Princeton WordNet. The first part generically describes the methodology we used as well the language resources that supported our approach. In the second part we will describe the tools that implemented this methodology and a quantitative account for the content of the Romanian wordnet at the time of this writing. Both the methodology and the tools are language independent, provided the necessary supporting language resources are in the required format.

In this paper we present a methodology for WordNet construction based on the exploitation of parallel corpora with semantic annotation of the English source text. We are using this methodology for the enlargement of the Spanish and Catalan versions of WordNet 3.0, but the methodology can also be used for other languages. As big parallel corpora with semantic annotation are not usually available, we explore two strategies to overcome this problem: to use monolingual sense tagged corpora and machine translation, on the one hand; and to use parallel corpora and automatic sense tagging on the source text, on the other. With these resources, the problem of acquiring a WordNet from parallel corpora can be seen as a word alignment task. Fortunately, this task is well known, and some aligning algorithms are freely available. WordNet versions in other languages are also availabe: in the EuroWord-Net project [26] WordNet versions in Dutch, Italian and Spanish have been developed; the Balkanet project [24] developed WordNets for Bulgarian, Greek, Romanian, Serbian and Turkish; and RusNet [2] for Russian, among others. On the Global WordNet Association 1 website a comprehensive list of WordNets available for different languages can be found. According to [26], we can distinguish two general methodologies for WordNet construction: (i) the merge model, in which a new ontology is constructed for the target language and relations between PWN and this local WordNet are generated; and (ii) the expand model, in which English variants associated with PWN synsets are translated following several strategies. In this work and for our purposes we are following this second strategy. The PWN is a free resource available at the University of Princeton website 2 . Many of the available WordNets for languages other than English are subject to proprietary licenses, although some others are available under free license, for example: Catalan [3], Danish [19], French WOLF WordNet [21], Hindi [23], Japanese [10], Russian [2] or Tamil [20] WordNets among others. The goal of this project is to enlarge and improve the Spanish and Catalan versions of WordNet 3.0 and distribute them under free license.

This paper explores the automatic construction of a multilingual Lexical Knowledge Base from preexisting lexical resources. First, a set of automatic and complementary techniques for linking Spanish words collected from monolingual and bilingual MRDs to English WordNet synsets are described. Second, we show how resulting data provided by each method is then combined to produce a preliminary version of a Spanish WordNet with an accuracy over 85%. The application of these combinations results on an increment of the extracted connexions of a 40% without losing accuracy. Both coarsegrained (class level) and fine-grained (synset assignment level) confidence ratios are used and evaluated. Finally, the results for the whole process are presented. *

The data compiled through many Wordnet projects can be a rich source of seed information for a multilingual dictionary. However, the original Princeton WordNet was not intended as a dictionary per se, and spawning other languages from it introduces inherent ambiguity that confounds precise inter-lingual linking. This paper discusses a new presentation of existing Wordnet data that displays joints (distance between predicted links) and substitution (degree of equivalence between confirmed pairs) as a two-tiered horizontal ontology. Improvements to make Wordnet data function as lexicography include term-specific English definitions where the topical synset glosses are inadequate, validation of mappings between each member of an English synset and each member of the synsets from other languages, removal of erroneous translation terms, creation of own-language definitions for the many languages where those are absent, and validation of predicted links between non-English pairs.

The present paper deals with the design and implementation of multilingual lexical resources of Assamese and Bodo Language with the help of Hindi Wordnet. Here, we present the multilingual dictionaries (for Hindi, Assamese and Bodo), synset based word search for Assamese-Hindi and Bodo-Hindi language. These words, of course, will have to go through some pre-processing before finally being uploaded to a database. The user-interface is being developed for specific language (Assamese, Bodo and Hindi language).

Computational Linguistics, 1999

WordNet, the on-line English thesaurus and lexical database developed at Princeton University by George Miller and his colleagues (Fellbaum 1998), has proved to be an extremely important resource used in much research in computational linguistics where lexical knowledge of English is required. The goal of the EuroWordNet project is to create similar wordnets for other languages of Europe. The initial four languages are Dutch (at the University of Amsterdam), Italian (CNR, Pisa), Spanish (Fundacion Universidad Empresa), and English (University of Sheffield, adapting the original WordNet); later Czech, Estonian, German, and French will be added. The results of the project will be publicly available. 1
