Data Extraction from the World Wide Web is a well known, non solved, and a critical problem when complex information systems are designed. These problems are related to the extraction, management and reuse of the huge amount of Web data available. These data have usually a high heterogeneity, volatility and low quality (i.e. format and content mistakes), so it is quite hard to build realible systems. In this chapter we propose an updated state of the art revision of the problem of Web Data Extraction, and an Evolutionary Computation approach based on Genetic Algorithms and Regular Expressions to the problem of automatically learn software entities. These entities, also called wrappers, will be able to extract some kind of Web data structures from examples.

Abstract.It is possible to create interactive, responsive web applications that allow user-generated contributions. However, the relevant technologies have to be explicitly deployed by the authors of the web pages. In this work we present the concept of parasitic and symbiotic web applications which can be deployed on arbitrary web pages by means of a proxy-based application platform. Such applications are capable of inserting, editing and deleting the content of web pages. We use an HTTP proxy in order to insert JavaScript code on each web page that is delivered from the web server to the browser. Additionally we use a database server hosting user-generated scripts as well as high-level APIs allowing for implementing customized web applications. Our approach is capable of cooperating with existing web pages by using shared standards (e.g. formatting of the structure on DOM level) and common APIs but also allows for usergenerated (parasitic) applications on arbitrary web pages without the need for cooperation by the page owner.

“…We will not talk about this subject further, preferring to concentrate on the other computational observables discussed in the Introduction. We just note that the vast literature on real-time reactive systems should be relevant in this context (e.g., see [6]), and that some Web-related work in this area has been carried out [12] and has found applications [27].…”

“…• WebL [27] is a language that specializes on fetching and processing Web pages. It uses service combinators [12] to retrieve streams of data from unreliable servers, and it uses a sophisticated pattern matching sublanguage for analyzing structured (but highly variable) data and reassembling it.…”
