We present an approach for automatic verification and augmentation of multilingual lexica. We exploit existing parallel and monolingual corpora to extract multilingual correspondents via triangulation. We demonstrate the efficacy of our approach on two publicly available resources: Tharwa, a three-way lexicon comprising Dialectal Arabic, Modern Standard Arabic and English lemmas among other inf...

We address the problem of performing polarity classification on Twitter over different languages, focusing on English and Spanish, comparing three techniques: (1) a monolingual model which knows the language in which the opinion is written, (2) a monolingual model that acts based on the decision provided by a language identification tool and (3) a multilingual model trained on a multilingual da...

The Dublin City University group participated in the monolingual, bilingual and multilingual retrieval tasks this year. The main focus of our investigation this year was extending our retrieval system to document languages other than English, and completing the multilingual task comprising four languages: English, French, Russian and Finnish. Results from our French monolingual experiments indi...

Cross Language Information Retrieval community has brought up search engines over multilingual corpora, and multilingual text categorization systems. In this paper, we focus on the multilingual clusters discovery problem, which aim is to extract topic-related multilingual document clusters from a multilingual document collection in an unsupervised way. Our approach is based on a linguistic anal...

In a context of the internationalisation of Higher Education (HE) driven by the high mobility of international Higher Degree Research candidates (HDRs), it is important to consider the value of HDRs’ multilingual capabilities for their learning and making of original contributions to knowledge. This article reports on a literature study regarding conceptualisations of multilingualism and multil...

Enhancing the development of multilingual lexicons is of foremost importance for intercultural collaboration to take place, as multilingual lexicons are the cornerstone of several multilingual applications. However, the development and maintenance of large-scale, robust multilingual dictionaries is a tantalizing task. In this paper we present a tool, based on a web service architecture, enablin...

This paper presents our new results on multilingual phone modeling and adaptation into a new target language which is not included in the trained multilingual models. The experiments were carried out with the SpeechDat(M) and MacroPhone databases including the languages French, German, Italian, Portuguese, Spanish and American English. First, we constructed language-dependent and multilingual p...

This paper proposes several improvements to multilingual training of neural network acoustic models for speech recognition and keyword spotting in the context of low-resource languages. We concentrate on the stacked architecture where the first network is used as a bottleneck feature extractor and the second network as the acoustic model. We propose to improve multilingual training when the amo...

The Cultural Heritage in CLEF 2013 lab comprised three tasks: multilingual ad-hoc retrieval and semantic enrichment in 13 languages (Dutch, English, German, Greek, Finnish, French, Hungarian, Italian, Norwegian, Polish, Slovenian, Spanish, and Swedish), Polish ad-hoc retrieval and the interactive task, which studied user behavior via log analysis and questionnaires. For the multilingual and Pol...

This report reviews the present state of the art in selection of texts in one language based on queries in another a problem we refer to as multilingual text retrieval Present applications of multilingual text retrieval systems are limited by the cost and complexity of developing and using the multilingual thesauri on which they are based and by the level of user training that is required to ac...
