|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...
Identifying Polarized Wikipedia Articles
Nikos Kirtsis, Paraskevi Tzekou, Jeries Besharat, Sofia Stamou.
Wikipedia is one of the most successful worldwide collaborative efforts to put together user-generated content in a meaningfully organized and intuitive manner. Currently, Wikipedia hosts millions of articles on a variety of topics, supplied by thousands of contributors. A critical factor in...
Ontology-Based Optimization in Search Engine
Leonardo Balduzzi, Ignacio Cuesta.
The major aim of the chapter is to propose and study the use of ontology-based optimization for positioning websites in search engines. In this sense, using heterogeneous inductive learning techniques and ontology for knowledge representation, a knowledge-based system which is capable of supporting the...
Mining Sentiment Using Conversation Ontology
Priti Srinivas Sajja, Rajendra Akerkar.
The research in the field of opinion mining has been ongoing for several years, and many models and techniques have been proposed. One of the techniques that can address the need for automated information monitoring to help to identify the trends and patterns that matter is sentiment mining. Existing...
Automatic Sentiment Analysis on Web Texts for Competitive Intelligence
Stanley Loh, Fabiana Lorenzi, Paulo Roberto Pasqualotti, Sabrina Ferreira Rodrigues, Luis Fernando Fortes Garcia, Valesca Persch Reichelt.
This chapter presents a software tool that helps the Competitive Intelligence process by collecting and analyzing texts published on the Internet. The goal is to automatically analyze indicators of the sentiment present in texts about a certain theme, whether positive or negative. The sentiment...
Ontology-Based Opinion Mining
Rajendra Akerkar, Terje Aaberge.
In this chapter, the authors discuss an ontology-based approach to opinion mining exploiting the possibility to represent commonly shared meaning of linguistic relations by ontologies. The ontology definitions are used as a standard to which sentences extracted from texts are compared. Unlike...
Intermediary Design for Collaborative Ontology-Based Innovation Monitoring
Jan Zibuschka, Uwe Laufs, Wolf Engelbach.
This chapter presents the architecture of an intermediary platform for networked open innovation management, as well as a surrounding sustainable business ecosystem. The instantiation presented here is tailored towards SMEs, both as stakeholders in the platform and as contributors in the modular...

AL-QuIn: An Onto-Relational Learning System for Semantic Web Mining
Francesca A. Lisi.
Onto-Relational Learning is an extension of Relational Learning aimed at accounting for ontologies in a clear, well-founded and elegant manner. The system QuIn supports a variant of the frequent pattern discovery task by following the Onto-Relational Learning approach. It takes taxonomic ontologies...
