WoNeF, an improved, extended and evaluated automatic French translation of WordNet Identifying the various possible meanings of each word of the vocabulary is a difficult problem that requires a lot of manual work. It has been tackled by the WordNet lexical semantics database in English, but there are still few …...

Symbolic and statistical learning for chunking : comparison and combinations We describe in this paper how to use grammatical inference algorithms for chunking, then compare and combine them to CRFs (Conditional Random Fields) which are known efficient for this task. Our corpus is extracted from the FrenchTreebank. We propose and …...

In this work, we present a new task for testing compositional distributional se- mantic models. Recently, there has been a spate of research into how distributional representations of individual words can be combined to represent the meaning of phrases. Vecchi et al. (2011) have shown that some compositional models, includ- …...

In this paper, we report on an unsupervised greedy-style process for acquiring phrase translations from sentence-aligned paral- lel corpora. Thanks to innovative selection strategies, this process can acquire multi- ple translations without size criteria, i.e. phrases can have several translations, can be of any size, and their size is not …...

Hungarian is the stereotype of morpholog- ically rich and free word order languages. Here, we introduce magyarlanc, a nat- ural language toolkit developed for the linguistic preprocessing – segmentation, morphological analysis, POS-tagging and dependency parsing – of Hungarian texts. We hope that the free availability of the toolkit fosters the …...

Translating verbs between MSA and arabic dialects through deep morphological analysis The developpment of NLP tools for dialects faces the severe problem of lack of resources for such dialects. In the case of diglossia, as in arabic, a variant of arabic, Modern Standard Arabic, exists, for which many resources have …...

Studying frequency-based approaches to process lexical simplification Lexical simplification aims at replacing words or phrases by simpler equivalents. In this paper, we present three models for lexical simplification, focusing on the criteria that make one word simpler to read and understand than another. We tested different contexts of the considered …...

Parallel areas detection in multi-documents for multilingual alignment This article broaches a central issue of the automatic alignment : diagnosing the parallelism of documents. Previous research was concentrated on the analysis of documents which are parallel by nature such as corpus of regulations, technical documents or simple sentences. Inversions and …...

This paper examines some popular misanalyses in Korean morphology. For example, contrary to popular myth, the verbal ha- and the element -(nu)n- cannot be analyzed as a derivational affix and as a present tense marker, respectively. We will see that ha- is an independent word and that -(nu)n- is part …...

In this paper, we propose a method for au- tomatic clause boundary annotation in the Hindi Dependency Treebank. We show that the clausal information implicitly encoded in a dependency structure can be made explicit with no or less human interven- tion. We exercised the proposed approach on 16,000 sentences of …...

This paper investigates the tonal patterns in the 15th century from a corpus-based approach, focusing on two historical sources, 日 本 館 譯 語 Rìbĕn kuăn yìyŭ ‘A Wordlist of Chinese-Japanese Phrases’ and 朝 鮮 館 譯 語 Cháoxiān kuăn yìyŭ ‘A Wordlist of Chinese- Korean Phrases’. The results suggest …...

This paper presents a novel method using graph-based semi-supervised learning (SSL) to improve the syntax parsing of unknown words. Different from conventional approaches that uses hand-crafted rules, rich morphological features, or a character-based model to handle unknown words, this method is based on a graph-based label propagation technique. It gives …...

In the development of corpus linguistics, the creation of corpora has had a critical role in corpus-based studies. The majority of created corpora have been associated with English and native languages, while other languages and types of corpora have received relatively less attention. Because an increasing number of corpora have …...

It has been generally assumed that a violation of island constraints indicates that the relevant syntactic phenomena involves movement. That is, if what look like displacements violate island constraints but remain acceptable, this means that they should not be derived by movement. A careful examination of postverbal constructions in Japanese …...

This paper proposes a guideline to determine Thai elementary discourse units (EDUs) based on rhetorical structure theory. Carson and Marcu’s (2001) guideline for segment- ing English EDUs is modified to propose a suitable guideline for segmenting EDUs in Thai. The proposed principles are used in tagging EDUs for constructing a …...

Semantic relation clustering for unsupervised information extraction Most studies in unsupervised information extraction concentrate on the relation extraction and few work has been proposed on the organization of the extracted relations. We present in this paper a two-step clustering procedure to group semantically equivalent relations : a first step clusters …...

Inductive and deductive inferences in a Crowdsourced Lexical-Semantic Network In Computational Linguistics, validated lexical-semantic networks are crucial resources. Regardless the construction strategies used, automatically inferring new relations from already existing ones may improve coverage and global quality of the resource. In this context, an inference engine aims at producing new …...

Frequent patterns are useful in many data mining problems including query suggestion. Frequent patterns can be mined through frequent pattern tree (FP- tree) data structure which is used to store the compact (or compressed) representation of a transaction database (Han, et al, 2000). In this paper, we propose an algorithm …...

Vietnamese accentless texts exist on paral- lel with official vietnamese documents and play an important role in instant message, mobile SMS and online searching. Under- standing correctly these texts is not sim- ple because of the lexical ambiguity caused by the diversity in adding diacritics to a given accentless sequence. …...

Identification, Alignment, and Tranlsation of Relational Adjectives from Comparable Corpora In this paper, we extract French relational adjectives and automatically align them with the nouns they are derived from by using a monolingual corpus. The obtained adjective-noun alignments are then used in the compositional translation of compound nouns of the …...
