[The Information Extraction problem (IE) refers to the automatic extraction of structured information from noisy unstructured textual sources. This problem is a research topic in different Computer Science communities, such as: Databases, Information Retrieval, and Artificial Intelligence. This...
[In the literature, different approaches have been proposed to address the problem of extracting valuable data from the Web. In this chapter is presented an overview of such approaches. It begins by presenting a broad set of Web extraction methods and tools. Following a taxonomy previously used...
[This chapter describes in detail a new approach for exploiting preexisting datasets to support Information Extraction by Text Segmentation methods. First, it presents a brief overview of the approach and introduces the concept of knowledge base. Next, it discusses all the steps involved in the...
[This chapter presents ONDUX (On Demand Unsupervised Information Extraction) a method that relies on the presented unsupervised approach to deal with the Information Extraction by Text Segmentation problem. ONDUX was first presented in Cortez et al. (2010) and in Cortez and da Silva (2010)....
[This chapter presents Joint Unsupervised Structure Discovery and Information Extraction (JUDIE) a method for addressing the IETS problem. JUDIE was presented in (Cortez et al. 2011). First, it is introduced the scenario to which JUDIE is targeted to, then we go over the proposed solution...
[This chapter presents iForm, a method for automatically using data-rich text for filling form-based input interfaces that rely on the presented unsupervised approach to deal with the Information Extraction by Text Segmentation problem. iForm was first presented in Toda et al. (2009, 2010). In...
[This chapter presents the conclusions and discuss directions for future work based on the unsupervised approach presented here.]
