In this paper we develop a formalization of semantic relations that facilitates efficient implementations of relations in lexical databases or knowledge representation systems using bases. The formalization of relations is based on a modeling of hierarchical relations in Formal Concept Analysis. Further, relations are analysed according to Relational Concept Analysis which allows a representati...

The meaning of a sentence in a document is more easily determined if its constituent words exhibit cohesion with respect to their individual semantics. This paper explores the degree of cohesion among a document's words using lexical chains as a semantic representation of its meaning. Using a combination of diverse types of lexical chains, we develop a text document representation that can be u...

Vector space models have been successfully used for lexical semantic representation. Some of these models rely on distributional properties of words in large corpora, and have been contrasted with human performance on semantic similarity and priming in lexical decision tasks. Neural network models of lexical representation have been classically of reduced size due to computational limitations. ...

The present article deals with the Italian lexical-semantic database Simple_PLUS and focuses on its essential core, i.e. the network of lexical semantic relations. This lexical resource builds on Parole-Simple-Clips, a four-layered electronic lexicon of Italian, founded on the SIMPLE model. Simple_PLUS consists of 30,000 semantic entries, partly imported from the source lexicon and partly newly...

This paper outlines current developments centering around the lexical-semantic database GermaNet and its applicability both within language engineering tasks and on the Semantic Web. From this perspective, representation and standardization are considered to be crucial issues as regards compatibility and interoperability with other languages resources. Representation variants of lexical data, e...

schema matching is a critical step in many applications, such as data warehouse loading, online analytical process (olap), data mining, semantic web [2] and schema integration. this task is defined for finding the semantic correspondences between elements of two schemas. recently, schema matching has found considerable interest in both research and practice. in this paper, we present a new impr...

In this paper, we present a computational approach to bilingual speakers’ non-native (L2) lexical-semantic representations. Specifically, based on detailed analyses of the error patterns shown in our previous simulation results ( Zhao and Li Int. J. Bilingual. Educ. Bilingual., 2010, 13, 505–524 ; Li, Bilingualism, 2013, 16, 288–303 ), aim at revealing underlying learning factors that may affec...
