This paper describes Meteor-WSD and RATATOUILLE, the LIMSI submissions to the WMT15 metrics shared task. MeteorWSD extends synonym mapping to languages other than English based on alignments and gives credit to semantically adequate translations in context. We show that context-sensitive synonym selection increases the correlation of the Meteor metric with human judgments of translation quality...

This paper presents a technique to build a lexical resource used for annotation of parallel corpora where the tags can be seen as multilingual ‘synsets’. The approach can be extended to add relationships between these synsets that are akin to WordNet relationships of synonymy and hypernymy. The paper also discusses how the success of this approach can be measured. The reported results are for E...

This work tries to enrich the Spanish Wordnet using a Spanish taxonomy as a knowledge source. The Spanish taxonomy is composed by Spanish senses, while Wordnet is composed by synsets (English senses). A set of weighted associations between Spanish words and Wordnet synsets is used for inferring associations between both taxonomies.

In this paper we present the Spanish version of WordNet 3.0. The English resource includes the glosses (definitions and examples) and the labelling of senses with WordNet identifiers. We have translated the synsets and the glosses to Spanish and alignment has been carried out at word level, whenever possible. The project has produced two interesting results: we have obtained a bilingual (Spanis...

We present a knowledge-rich methodology for disambiguating Wikipedia categories with WordNet synsets and using this semantic information to restructure a taxonomy automatically generated from the Wikipedia system of categories. We evaluate against a manual gold standard and show that both category disambiguation and taxonomy restructuring perform with high accuracy. Besides, we assess these met...

Representations in WordNet are not on the level of individual words or word forms, but on the level of word meanings (lexemes). A word meaning, in turn, is characterized by simply listing the word forms that can be used to express it in a synonym set (synset). As a result, the meaning a word in WordNet is determined by its sets of synonyms. This is essentially a recursive definition of word mea...

In the last years, at the Institute for Computational Linguistics in Pisa, a few lexical resources have been developed aiming at encoding complex lexical semantic information. ItalWordNet and SIMPLE are two of these resources which, tackling semantics in the lexicon from different points of view, and being at least partially complementary, could certainly profit from linking each other. These r...

The detection of event mentions in free text is a key to a deeper automatic understanding of the text’s contents. In this paper we present ongoing work on mechanisms to detect events in German texts in the domain of cultural heritage documentation. A central role plays a hand-crafted mapping of CIDOC CRM events to GermaNet synsets to ease the process of creating a lexicon for automatic event de...

Gujarati is one of the 22 official languages of India. It is an Indo-Aryan language descended from Sanskrit. Gujarati wordnet is being built using expansion approach with Hindi as the source language. This paper describes experiences of building Gujarati wordnet. Paper discusses basic features of Gujarati language and evaluates suitability of Hindi language for expansion approach. Various issue...

OBJECTIVE Synonym-substitution algorithms have been developed for the purpose of matching source vocabulary terms with existing Unified Medical Language System (UMLS) terms during the integration process. A drawback is the possible explosion in the number of newly generated (potential) synonyms, which can tax computational and expert review resources. Experiments are run using a synonym-substit...
