Semantic Catalogue to Manage Data Sources in Disaster Management System
2016
International audience; With the climate change, disasters occur more frequently and the need for efficient disaster management systems becomes highly recommended to save lives. This paper deals with a study of existing systems, with the intention of determining the main recent improvement in the domain. The heterogeneous data integration process is a major central point. Thus, a semantic system with three main components is proposed as a new position in the disaster management systems. These three components are a knowledge base, a reasoner and a semantic catalogue. The knowledge base provides a controlled vocabulary and allows storing information retrieval. The semantic catalogue facilita…
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…
Semantic sense extraction from Wikipedia pages
2010
This paper presents a technique aimed to extract structured information from unstructured Wikipedia contents related to a particular topic, and to arrange it in a semantic way inside an ontology. The general framework is the design of an artificial agent able to deliberate when increasing its domain knowledge. In particular, this cognitive agent acts as a dialogue manager in an Intelligent Tutoring System (ITS) already presented by the authors. Our approach is based on the definition of useful patterns able to extract and identify novel concepts and relations to be added to the knowledge base. We propose a method that uses information from the wiki page’s structure. We define different stra…

Seamless Learning Environments in Higher Education with Mobile Devices and Examples
2016
The use of seamless learning environments that have the potential to support lifelong learning anytime and anywhere has become a reality. In this sense, many educational institutions have started to consider introducing seamless learning environments into their programs. The aim of this study is to analyze how various educational university programs implement the design elements for seamless learning environments with mobile devices. For that purpose, three cases involved in a Finnish teaching development project are explored by conducting semi-structured interviews with key participants. The themes of the interviews were related to the theoretical background for (mobile) seamless learning …
Lo strano caso di Susan Boyle. Ovvero, quando la comicità diventa virale
2016
Era l’11 aprile 2009, quando Susan Boyle si presentò alle audizioni del celebre talent show inglese Britain’s got talent,. Allora non era che una strana signora di 47 anni con una storia al limite del disagio psichico alle spalle: non aveva lavoro, non era mai stata fidanzata – mai neanche baciato un uomo a sentir lei – e viveva con il gatto Pebbles in una specie di piccolo villaggio scozzese. Perché il sogno della Boyle si realizzasse sarebbero dovuti passare solo sette mesi, un record assoluto nell’industria discografica ormai in atavica crisi. Il 23 novembre del 2009, infatti, uscì il suo primo disco da solista. Un album che è stato uno dei maggiori successi dell’industria discografica d…

PlaToLoCo: the first web meta-server for visualization and annotation of low complexity regions in proteins
2020
Abstract Low complexity regions (LCRs) in protein sequences are characterized by a less diverse amino acid composition compared to typically observed sequence diversity. Recent studies have shown that LCRs may co-occur with intrinsically disordered regions, are highly conserved in many organisms, and often play important roles in protein functions and in diseases. In previous decades, several methods have been developed to identify regions with LCRs or amino acid bias, but most of them as stand-alone applications and currently there is no web-based tool which allows users to explore LCRs in protein sequences with additional functional annotations. We aim to fill this gap by providing PlaToL…
Bot or Not? A Case Study on Bot Recognition from Web Session Logs
2019
This work reports on a study of web usage logs to verify whether it is possible to achieve good recognition rates in the task of distinguishing between human users and automated bots using computational intelligence techniques. Two problem statements are given, offline (for completed sessions) and on-line (for sequences of individual HTTP requests). The former is solved with several standard computational intelligence tools. For the second, a learning version of Wald’s sequential probability ratio test is used.
