Abstract
Web 2.0 Applications have gained much power and usability in the last years. A particular case is medicine Web sites, like forums, wikis, and others. In most cases, these sites provide general information without making contact with the physicians. On other side, the CDSS (Clinical Decision Support Systems) are very useful applications, and many of them are ontology based. In this chapter, the authors propose a social Web application that allows patients to make contact with their physicians through a CDSS list of signs. This application combines social Web, CDSS, and Web services.

EduOntoWiki Project for Supporting Social, Educational, and Knowledge Construction Processes with Semantic Web Paradigm
An ontology is a formal representation of knowledge about an area of interest. The part of the world conceptualized or described is called the “knowledge domain.” Ontologies provide a vocabulary for representing and communicating knowledge domains and a set of relationships that hold among the terms in that vocabulary.

Ontological Dimensions of Semantic Mobile Web 2.0: First Principles
According to T. Gruber, an ontology is a “formal, explicit specification of a shared conceptualization”. This implies that ontologies provide a shared formal common language for modeling features of domain discourse.

Teaching and Learning with Mobile Technologies
An ontology is an explicit, formal specification of a shared conceptualization of a domain of interest. This indicates that an onotology should be machine readable (which excludes natural language). It indicates that it captures consensual knowledge, that is not private to an individual, but accepted as a group or committee of practice. The reference to a domain of interest indicates that domain ontologies do not model the whole world, but rather modeling just parts, which are relevant to the task at hand.

Knowledge Management for E-Government Applications and Services
An explicit formal specification of how to represent objects, concepts and other entities that are assumed to exist in some area of interest and relationships holding among them. Systems that share the same ontology are able to communicate about domain of discourse without necessarily operating on a globally shared theory. System commits to ontology if its observable actions are consistent with definitions in the ontology.

Educational Technology Standards in Focus
Ontologies are used to logically represent concepts and the relationships that make up the concepts. In learning technologies, ontologies are important because they have the potential to be used, in combination with metadata representations, particularly RDF representations, so that intelligent data systems can apply logic and rule-based reasoning to learning objects.
