La variable 'sexe' en les llengües del món
2013
El sexe és una de les variables més freqüents en els diferents recursos lingüístics per a identificar els interlocutors en les llengües del món. El fet que s'hagi confós el gènere gramatical (procediment de classificació dels substantius) amb el sexe, i la consegüent inclusió dels elements identificadors en la categoria «gènere», ha provocat una certa confusió sobre la naturalesa d'aquests fenòmens. En l'article es proposa una classificació en quatre tipus dels mecanismes per a la identificació dels interlocutors en la llengua, per bé que tots poden ser entesos com a part d'un continu que va des dels elements gramaticals obligatoris fins als lectes específics per a homes i dones. Entremig, …
Naming MINERALITY of French white wines : a contrastive study on the emergence of a " new " wine descriptor
2016
International audience; [Context] MINERAL / MINERALITY has emerged in wine prescriptive and descriptive discourses for about 20 years, especially to characterize special kinds of French white wines like Chablis in Northern Burgundy. Despite its very popular use by both experts and consumers, it still lacks a terminological definition that would be accepted by all wine professionals. For this reason, a research program was conducted in the last two years by an interdisciplinary team at the University of Burgundy and the Wine School of Changins (Switzerland) in order to cross semantic and sensory data enabling the establishment of a prototypical definition.[Aims] Building on the results of th…
A Geometric Algebra Based Distributional Model to Encode Sentences Semantics
2013
Word space models are used to encode the semantics of natural language elements by means of high dimensional vectors [23]. Latent Semantic Analysis (LSA) methodology [15] is well known and widely used for its generalization properties. Despite of its good performance in several applications, the model induced by LSA ignores dynamic changes in sentences meaning that depend on the order of the words, because it is based on a bag of words analysis. In this chapter we present a technique that exploits LSA-based semantic spaces and geometric algebra in order to obtain a sub-symbolic encoding of sentences taking into account the words sequence in the sentence. © 2014 Springer-Verlag Berlin Heidel…
A hybrid approach to semantic web services matchmaking
2008
AbstractDeploying the semantics embedded in web services is a mandatory step in the automation of discovery, invocation and composition activities. The semantic annotation is the “add-on” to cope with the actual interoperability limitations and to assure a valid support to the interpretation of services capabilities. Nevertheless many issues have to be reached to support semantics in the web services and to guarantee accurate functionality descriptions. Early efforts address automatic matchmaking tasks, in order to find eligible advertised services which appropriately meet the consumer’s demand. In the most of approaches, this activity is often entrusted to software agents, able to drive re…
A Community-based Approach for Service-based Application Composition in an Ecosystem
2010
The design of composite applications by combining existing services with known semantics is an ongoing topic in current research. Several studies are aimed at providing service description models and standards, service discovery and matching etc. However, service composition in distributed dynamic environments such as P2P ecosystems has received little attention from research communities. In this paper we present a design framework for composing services, taking in particular into account different ways of building peercommunities based on network or services characteristics.
Ontology-based service matching and discovery
2011
In this paper we consider ontologies as knowledge structures that specify attributes of services, their properties and relations among them to enable finding semantic similarity between service descriptions and service requests. Ontologies reflect semantic relationship between concepts represented by attributes in service descriptions and service requests. We use knowledge from ontologies to enhance the both user service requests and service descriptions by adding concepts that are not presented in the original descriptions, and use them in comparison process. It results in more precise matching since we consider also implicit concepts. Thus services and requests that do not contain exact m…
Similarity estimation module for OWSCIS
2008
Semantic interoperability based on ontologies is nowadays becoming a great challenge. We propose an architecture for semantic-based cooperation called OWSCIS (Ontology and Web Service based Cooperation of Information Sources). It allows to map various information sources using ontologies and to answer users' queries over the cooperation. In this paper we focus on the similarity estimation service of the OWSCIS Architecture which allows to discover mappings between different ontologies. It relies on various mappings methods which are combined and refined to semi-automatically generate mappings between a local and a reference ontologies.
A Multi-channel Communication Framework
2013
We present a modular framework for a business-to-customer communication service integrating several communication channels. Using such a service it is possible to find hidden relationships between messages and thus collect more customer-related data. The framework core is a message-conversion engine capable of converting channel-independent abstract messages into concrete messages and vice-versa. The conversion process is context-dependent. The context consists of formally described communication channel characteristics and user preferences. The framework is based on semantic technologies due to a balance between their expressive power, reasoning properties, and existence of production-qual…
Mobile agents and grid computing
2004
Publisher Summary This chapter describes mobile agents as an effective solution for grid service provision. A short overview is first introduced on the grid paradigm and the most known research activities in the field. Then, mobile agents are discussed and a comparison with the remote procedure call (RPC) method is made as far as the most effective solution to minimize network overload and fault occurrences is concerned. The common feature of all grid architectures is a coordinated and controlled resource sharing between the members of a dynamic multi-institutional virtual community. Community members agree on a set of sharing rules and permissions, by which resources to be shared and membe…
Looking Beyond Genres: Identifying Meaningful Semantic Layers from Tags in Online Music Collections
2011
A scheme for identifying the semantic layers of music-related tags is presented. Arguments are provided why the applications of the tags cannot be effectively pursued without a reasonable understanding of their semantic qualities. The identification scheme consists of a set of filters. The first is related with social consensus, user-count ratio, and n-gram properties of tags. The next relies on look-up functions across multiple databases to determine the probable semantic layer of each tag. Examples of the semantic layers with prevalence rates are given based on application of the scheme to a subset of the Million Song Dataset. Finally, a validation of the results was carried out with an i…
