Um ambiente para recuperação semântica de informação em governo eletrônico: um estudo de caso em licitações públicas

Abstract

The treatment given to the great volume of information produced under optics of the government represents a critical factor of success for diverse types of relationships that involve the public administration: Government and Citizen, Government and Private Sector, Government e other agencies and spheres of the Government and Government and the Government Employee. As we are facing a digital imminently society, it becomes viable to use the technology to dissemination of this information and, in this case, the Internet is quite appropriate. However, nding the desired information in the immensity of existing documents on the Web is a very hard task. To make this easier, the use of Semantic Web technology appears as a promising alternative. Thus, the SemanticWeb architecture expedites the information sharing that is continuously generated and by all kind of sources of information in a typical e-Gov environment. Therefore, citizens, companies or other government spheres nd a e cient way of relationship with the government. This research is about the use of Ontologies and proposes an environment based in software agents to search for information on the Web. Ontologies make easier having a standard formatting for publish contents, while the searching and the information's recommendation is automated by software agents. A catalog of web pages, widely used in Web search tools from the beginning, is also used by the prototype to catalog Ontologies and RDF pages. This catalog is used to guide the searching of Web pages, semantically marked up, which meet the search preset criteria choosed by the users. The proposed environment also includes the information recommendation found in RDF pages. In this case study, the recommendations will be used in information about public tenders. Creating an environment for semantic search of information made it possible to decrease the e ort required to information exchange on the Internet, increasing, signi cantly, the chances of success of e-Gov initiatives. In addition, the solution proved feasible to any context that, like the e-Gov, provides a great volume of heterogeneous information and uses the Internet as a form of publicizing.
