Abstract(s)
Na Web, existem grandes quantidades de informação não-estruturada relativa a indivíduos. Ler toda essa informação, até que se pudesse saber mais acerca de uma pessoa específica, tomaria muito tempo. Enquanto, no passado, seria necessário pesquisar um grande número de websites, individualmente, para que se encontrasse a informação pretendida, este consumo de tempo pode agora ser evitado pelo uso de uma
aplicação informática que desempenha a mesma tarefa mais rapidamente e de forma automática. A informação pode, depois, ser armazenada em bases de dados para sua posterior utilização para os mais diversos fins.
The topic of this dissertation is a relation extraction system for people search on the web. Nowadays, a big amount of search queries on the internet are about people. In general, people can be described by their attributes, such as profession, place of birth, or places where they lived. The present work focuses on sentences which express the relation between a person and a respective attribute. It adapts a mechanism of distant supervision, developed by Mintz et al. (Mintz et al., 2009), which has the underlying intuition that a sentence containing two entities which are known to stand in a certain relation to each other, is likely to express this relation in some way.
