Proposal of an Architecture to Retrieve Information from Multiple Devices Using Matchmaking Algorithms
2007
Semantic Web services (SWS) propose to extend the traditional Web services technologies on the way to consolidate ontologies and semantics. This makes possible the selection, the integration and the dynamic invocation of services. In this way, services are able to dynamically adapt themselves to changes without human intervention. The main purpose of this paper is to present an algorithm for matching SWS. The algorithm uses the description of the services capabilities to match the semantic values. The traditional matching has been improving using ontologies witch constitutes a step further in the matching algorithms. To implement the algorithm an agent FIPA compliant architecture has been d…
Semantics
2020
There are many different ways of defining the word “semantics”. For instance, according to Eco (2017: 550–551), it is possible to distinguish at least five senses of semantics. That is to say: a. Semantics as the study of the meaning of terms removed from any context [...]; b. Semantics as the study of content systems or structural semantics [...]; c. Semantics as the study of the relation between term (or sentence) and referent, or as the study of reference [...]; d. Semantics as the study of the truth conditions of propositions expressed by sentences; e. Semantics as the study of the particular meaning that terms or sentences assume in context or in the text as a whole [...]; With particu…
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…
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.
Filosofia come design concettuale. Mari e Floridi: etica, physis e techné nell’infosfera
2022
Partendo da una rilettura di 25 modi per piantare un chiodo di Enzo Mari - e in generale della sua poetica - il contributo prova e mettere in evidenza alcune riflessioni che oggi, come allora, alimentano il dibattito contemporaneo sul design, sulla socio-tecnosfera e in generale sull’uomo e il suo habitat. Passando in rassegna alcuni suoi racconti e microstorie autobiografiche, discussioni teoriche o esempi concreti, è possibile rintracciare una serie di questioni chiave e linee di pensiero che, trascendendo i confini strettamente disciplinari, approdano a riflessioni di più ampio respiro di carattere etico e filosofico. Tali questioni, nella presente trattazione, sono messe in serrata conn…
Sine cura. Verso il ri-ciclo dell'architettura del secondo Novecento
2019
Gli argomenti discussi nel saggio interrogano il destino che il Codice dei Beni Culturali (2004- 2011) determina per le opere del secondo Novecento. Nella costruzione del futuro di questi manufatti, che per funzione, tecnologia e cicli d’uso sono spesso segnati dall’obsolescenza e dall’abbandono, le ambiguità e le incongruenze delle attuali procedure legislative sollecitano profondamente il ruolo culturale delle esperienze di ricerca che usano metodologie meta progettuali. Il confronto fra alcuni casi italiani ed altri europei rimarca il ruolo del progetto nella costruzione di una prospettiva di tutela trasformativa per il costruito del secondo Novecento. Nel quadro di azione marcato dall’o…
Inferring Business Rules from Natural Language Expressions
2014
This paper proposes a mapping technique for automatically translating rules expressed in a format based on natural language, i.e. Semantics of Business Vocabulary and Business Rules (SBVR) standard, into production rules that can be executed by a computer (i.e. Rule engine). The proposed approach achieves a twofold purpose: on the one hand non IT skilled people (i.e. Domain expert) can effectively focus on business rules definition by using statements in natural language, and on the other hand the IT staff will have to manage business rules in a format ready to be executed by a rule engine. The main goal is to overcome some weaknesses in the software development process that could produce i…
Improving Assessment of Students through Semantic Space Construction
2009
Assessment is one of the hardest tasks an Intelligent Tutoring System has to perform. It involves different and sometimes uncorrelated sub-tasks: building a student model to define her needs, defining tools and procedures to perform tests, understanding students' replies to system prompts, defining suitable procedures to evaluate the correctness of students' replies, and strategies to improve students' abilities after the assessment session.In this work we present an improvement of our system, TutorJ, with particular attention to the assessment phase. Many tutoring systems offer only a limited set of assessment options like multiple-choice questions,fill-in-the-blanks tests or other types …
