Lexical cohesion arises from a chain of lexical items that establish links between sentences in a text. In this paper we propose three different models to capture lexical cohesion for document-level machine translation: (a) a direct reward model where translation hypotheses are rewarded whenever lexical cohesion devices occur in them, (b) a conditional probability model where the appropriatenes...

We describe the results of a syntactic-semantic parser for Cobuild dictionary definitions. Unlike previous work on the automatic analysis of machine readable dictionaries, the particular structure of the Cobuild definition allows us to derive information that classifies the lexical item mainly in terms of the selectional restrictions or preferences encoded on its arguments. The resulting formal...

We evaluate two types of lexical resources with respect to their applicability to interlingual machine translation: (1) a EuroWordNetbased database of bilingual links between Spanish and English words; and (2) a repository of semantically classified verbs with their corresponding Lexical Conceptual Structure (LCS) representations. We examine the utility of these two resources for the task of le...

In this paper, we present Lexical Episode Plots, a novel automated text-mining and visual analytics approach for exploratory text analysis. In particular, we first describe an algorithm for automatically annotating text regions to examine prominent themes within natural language texts. The algorithm is based on lexical chaining to find spans of text in which the frequency of a term is significa...

This paper presents the morphosemantic field model, claiming that it is relevant in the description of lexical structures in grammatically-motivated languages such as Croatian. Arguments are presented for the applicability of the model in synchronic and diachronic lexical analysis. The fact that many characteristics of morphosemantic fields are compatible with the theoretical framework of cogni...

We describe a novel method for automatically generating hypertext links within and between newspaper articles. The method is based on lexical chaining, a technique for extracting the sets of related words that occur in texts. Links between the paragraphs of a single article are built by considering the distribution of the lexical chains in that article. Links between articles are built by consi...

The aim of this paper is to diagnose the sufficiency first-year pedagogy students’ discoursive competence, considering lexical, reading comprehension and written competences. Whit objective, three instruments were designed adapted, one for each competence: lexical availability test, test rubric evaluate an argumentative writing task. Among main findings, it stands out that highest performance c...

Wikipedia is a Web based, freely available multilingual encyclopedia, constructed in a collaborative effort by thousands of contributors. Wikipedia articles on the same topic in different languages are connected via interlingual (or translational) links. These links serve as an excellent resource for obtaining lexical translations, or building multilingual dictionaries and semantic networks. As...

This article presents the transformation of the noun-related part of WordNet (108,000 nouns, 74,500 categories representing their meanings, and 95,000 semantic links between them) into a genuine “lexical ontology”, usable for knowledge representation, sharing and retrieval on the Web. To do so, (i) I generated intuitive identifiers for all the categories, (ii) introduced 353 lexical corrections...
