Data integration is one of the older research fields in the database area and has emerged shortly after database systems were first introduced into the business world. In this paper, we briefly introduce the problem of integration and, based on an architectural perspective, give an overview of approaches to address the integration issue. We discuss the evolution from structural to semantic inte...

This paper introduces PersPred, the first manually elaborated syntactic and semantic database for Persian Complex Predicates (CPs). Beside their theoretical interest, Persian CPs constitute an important challenge in Persian lexicography and for NLP. The first delivery, PersPred 11, contains 700 CPs, for which 22 fields of lexical, syntactic and semantic information are encoded. The semantic cla...

This paper analyzes the contribution of semantic roles to TimeML event recognition and classification. For that purpose, an approach using conditional random fields with a variety of morphosyntactic features plus semantic roles features is developed and evaluated. Our system achieves an F1 of 81.4% in recognition and a 64.2% in classification. We demonstrate that the application of semantic rol...

This paper is about the relations between the concept of Semantic Domain and the “Theory of Semantic Fields”, a structural model for lexical semantics proposed by Jost Trier at the beginning of the last century. The main limitation of the Trier’s notion is that it does not provide an objective criterion to aggregate words around fields, making the overall model too vague, and then unuseful for ...

Human-to-human conversation remains such a significant part of our working activities because of its naturalness. Multimodal interaction systems combine visual information with voice, gestures, and other modalities to provide flexible and powerful dialogue approaches. The use of integrated multiple input modes enables users to benefit from the natural approach used in human communication. In th...

Based on integrated infrastructure of resource sharing and computing in distributed environment, cloud computing involves the provision of dynamically scalable and provides virtualized resources as services over the Internet. These applications also bring a large scale heterogeneous and distributed information which pose a great challenge in terms of the semantic ambiguity. It is critical for a...

In this paper I we will compare the semantic fields of conflict and non-conflict (conflict handling) in Swedish and Malay. For an introduction to concept of “semantic fields”, cf Trier (1931), Weisgerber (1953-54), Lehrer (1974), Lyons (1977). The study covers words which may be used to refer to or describe conflict and non-conflict (conflict handling), rather than words by which conflict could...

The article describes a model of automatic interpretation of English puns, based on Roget’s Thesaurus, and its implementation, PunFields. In a pun, the algorithm discovers two groups of words that belong to two main semantic fields. The fields become a semantic vector based on which an SVM classifier learns to recognize puns. A rule-based model is then applied for recognition of intentionally a...

this paper examines the semantic contribution of -?r and -andeh suffixes in persian based on lieber’s (2004) lexical semantic representation. this framework using six semantic features ([material], [dynamic], [location], [ieps] , [b] and [ci] and a principle called coordination principle studies the semantic contribution of lexical items including affixes and their functions in compounding, der...
