ExtraWeb: um sumarizador de documentos Web baseado em etiquetas HTML e ontologia

This dissertation presents an automatic summarizer of Web documents based on both HTML tags and ontological knowledge. It has been derived from two independent approaches: one that focuses solely upon HTML tags, and another that focuses only on ontological knowledge. The three approaches were implemented and assessed, indicating that associating both knowledge types have a promising descriptive power for Web documents. The resulting prototype has been named ExtraWeb. The ExtraWeb system explores the HTML structure of Web documents in Portuguese and semantic information using the Yahoo ontology in Portuguese. This has been enriched with additional terms extracted from both a thesaurus, Diadorim and the Wikipedia. In a simulated Web search, ExtraWeb achieved a similar utility degree to Google one, showing its potential to signal through extracts the relevance of the retrieved documents. This has been an important issue recently. Extracts may be particularly useful as surrogates of the current descriptions provided by the existing search engines. They may even substitute the corresponding source documents. In the former case, those descriptions do not necessarily convey relevant content of the documents; in the latter, reading full documents demands a substantial overhead of Web users. In both cases, extracts may improve the search task, provided that they actually signal relevant content. So, ExtraWeb is a potential plug-in of search engines, to improve their descriptions. However, its scability and insertion in a real setting have not yet been explored.
Abordagem para diagnóstico de problemas em aplicações de E-GOV - um retrato dos municípios brasileiros.
(Universidade Federal de São Carlos, 2006-07-10) Bittar, Thiago Jabur; Silva, Junia Coutinho Anacleto; https://lattes.cnpq.br/6200743168568684
In this work, the main theme is to collect data to diagnose problems and formalize solutions in the Brazilian municipal Electronic Government (E-GOV) domain, focusing on G2C (Government to Citizen) at the first moment. In order to do that, this research analyses and relates: the main problems and challenges to promote E-GOV in general terms and in Brazilian cities as well as in cities from all over the world; the Legislation and guidelines of E-GOV project. So, it was developed a methodological approach composed by a group of methods and complementary macro-activities to scale the results understanding up, supporting the building and spreading of a significant, valid and widespread knowledge in this domain. Such macro-activities used to gather the data are: (i) investigating cities information automatically, (ii) contacting the Administrations via a marketing research and (iii) evaluating the sites by inspection in order to validate the diagnosis. Thus, once the problem recurrence is verified and a successful solution is observed, a propitious base of information is configured so that Proto-Patterns can be identified and formalized as a structured and elegant way to document and diffuse the solutions in the context of E-GOV development to cities, relating to the Software Engineering (SE) and Human-Computer Interaction (HCI) domains.
