Monografia Acesso aberto Busca semântica de informações nas redes sociais(2011) Silva, João Caibar da; Andriani, Mateus LohnSocial media grew exponentially in recent years. Users who participate in these networks are responsible for preparing the content, which can be provided, for example, in the way of publications, comments or ratings. This content may contain information that is of interest to people who were not involved during its preparation. However, it is usually dispersed among publications with different subjects and purposes, which makes harder its location. The objective of this work is the development of an information extractor for social medias that performs the filtering of the published content, thereby showing only the information of interest to the user. Twitter was chosen as the domain of research for information extraction. To perform the integration with Twitter, an analysis of the components available for the Java programming language that enables the integration with Twitter was developed. The result of this work was the development of two tools. The Livesearch, which was the first tool developed, queries for publications on Twitter and allows the use of a series of filters through an interface built in HTML. The Livesearch S, which was developed later, adds the ability to conduct queries with the help of a semantic thesaurus, which increases the number of results, in addition to using AJAX requests for navigation between paged results.
