|Advancing Information Management through Semantic Web Concepts and Ontologies
Patricia Ordóñez de Pablos, Héctor Oscar Nigro, Robert D. Tennyson, Sandra Elizabeth Gonzalez Cisaro, Waldemar Karwowski.
Although the majority of information that is published by the current web is aimed at human consumption, the browsers which contain this information are only able to interpret HTML mark-up to visualize this content. Semantic web intends to address the stability between human and machine.Advancing...
Cases on Open-Linked Data and Semantic Web Applications
Patricia Ordóñez de Pablos, Miltiadis D. Lytras, Robert D. Tennyson, José Emilio Labra Gayo.
With the purpose of building upon standard web technologies, open linked data serves as a useful way to connect previously unrelated data and to publish structured data on the web. The application of these elements leads to the creation of data commons called semantic web.Cases on Open-Linked Data and...
Emergent Ontologies by Collaborative Tagging for Knowledge Management
Weena Jimenez, César Luis Alvargonzález, Pablo Abella Vallina, Jose María Álvarez Gutiérrez, Patricia Ordóñez de Pablos, Jose Emilio Labra Gayo.
The massive use of Internet and social networks leads us to a new dynamic environment with huge amounts of unstructured and unclassified information resources in continuous evolution. New classification, compilation, and recommendation systems based on the use of folksonomies and ontologies have...
Visualizing Design Project Knowledge on a Collaborative Web 2.0 Platform
Vadim Ermolayev, Frank Dengler.
The chapter reports the implementation and validation of the knowledge process visualization technology that extends the basic capabilities of the Semantic MediaWiki platform. The Design Project Visualizer has been developed in the ACTIVE Integrating Project of the Seventh Framework Programme of the...
Multimedia Systems Development
Miloš Milovanovic, Miroslav Minovic, Velimir Štavljanin, Dušan Starcevic.
The multimedia information system represents a specific form of information system. This research area suffered many changes in direction due to technology shifts. The general problem is that few years back, multimedia technologies had been limited to relatively simple, stand-alone applications, but...
Sem-IDi: Research and Development Management Enabled by Semantics
Ricardo Colomo-Palacios, Diego Jiménez-López, Marcos Ruano-Mayoral, Joaquín Fernández-González, David Mayorga Martín, Alberto López Fernández, Rocío Vega Alonso.
The increasing strength and usefulness of semantic technologies have led to innovative decision support processes and management of partners and R&D call for proposals. This book chapter introduces the SEM-IDi project, an architecture that integrates R&D processes with project management software and...
Semantic Web Data Partitioning
Trupti Padiya, Minal Bhise, Sanjay Chaudhary.
Semantic Web database is an RDF database due to increased use of Semantic Web in real life applications; one can find heavy growth in RDF database. As there is a tremendous increase in RDF data, performance and scalability issues are of main concern. This chapter discusses improving and scaling up...
Metamodels Construction Based on the Definition of Domain Ontologies
Carlos Enrique Montenegro-Marin, Rubén González Crespo, Oscar Sanjuán Martínez, Juan Manuel Cueva Lovelle, B. Cristina Pelayo García-Bustelo, Patricia Ordóñez de Pablos.
This chapter proposes a mechanism for mapping domain ontologies to metamodels by a direct mechanism; this proposal is necessary because there is no formal mechanism for obtaining requirements in model driven engineering. Specifically, here the authors propose the use of a domain ontology as the main...
Enhancing Information Extraction with Context and Inference: The ODIX Platform
Hisham Assal, Franz Kurfess, Kym Pohl, Emily Schwarz, John Seng.
Natural Language Processing (NLP) provides tools to extract explicitly stated information from text documents. These tools include Named Entity Recognition (NER) and Parts-Of-Speech (POS). The extracted information represents discrete entities in the text and some relationships that may exist among...
An Ontology-Based Search Tool in the Semantic Web
Constanta-Nicoleta Bodea, Adina Lipai, Maria-Iuliana Dascalu.
The chapter presents a meta-search tool developed in order to deliver search results structured according to the specific interests of users. Meta-search means that for a specific query, several search mechanisms could be simultaneously applied. Using the clustering process, thematically homogenous...

Semantic web continues to be an increasingly important system for allowing end-users to share and communicate information online.Semantic Web: Ontology and Knowledge Base Enabled Tools, Services and Application focuses on the information systems discipline and the tools and techniques utilized for the...
Providing Information from Brazilian Politicians Using Linked Data
Jairo Francisco de Souza, Sean Wolfgand M. Siqueira, Lucas de Ramos Araújo, Rubens Nascimento Melo.
Since its inception, the Web has undergone continuous evolution in order to improve itself as a means of global communication and information sharing. Open Government Data are increasingly being published on the Web, contributing to the transparency and the reusability of public data. At the same time...
A Semantic Framework for Touristic Information Systems
Salvador Lima, José Moreira.
The Web is a crucial means for the dissemination of touristic information. However, most touristic information resources are stored directly in Web pages or in relational databases that are accessible through ad-hoc Web applications, and the use of automated processes to search, extract and interpret...
Semi-Automatic Knowledge Extraction to Enrich Open Linked Data
Elena Baralis, Giulia Bruno, Tania Cerquitelli, Silvia Chiusano, Alessandro Fiori, Alberto Grand.
In this chapter we present the analysis of the Wikipedia collection by means of the ELiDa framework with the aim of enriching linked data. ELiDa is based on association rule mining, an exploratory technique to discover relevant correlations hidden in the analyzed data. To compactly store the large...
Variables Performance for E-Services Acceptance: A Descriptive Statistical Analysis
This case study examines the Web Electronic Service framework for a University in Australia. The department is in the process of developing and implementing a Web-based e-service system. The user experience to use e-services requires insight into the attributes that shape the experience variable. The...
News Trends Processing Using Open Linked Data
Antonio Garrote, María N. Moreno García.
In this chapter we describe a news trends detection system built with the aim of detecting daily trends in a big collection of news articles extracted from the web and expose the computed trends data as open linked data that can be consumed by other components of the IT infrastructure. Due to the sheer...
