Nowadays the Web is the biggest and the most dynamic information repository in the world. This presents an important opportunity to improve and develop both retrieval and extraction techniques for Web information. This involves different kinds of data such as: text, semistructured data, images, sound, and so on; and, on the other hand, it’s important to take advantage of the hypertextual structure of the Web and the behaviour of the users that have been registered both on the web servers and on web specific applications such as search engines.
In this way, the main purpose of this group includes the study of every kind of problem related with the better understanding of the Web, making use of its information and easy access.
WRG/UPF Researchers David Nettleton and Anton Dries recently (July 2013) submitted a European Patent application for a "local neighbourhood sub-graph matching method" which uses heuristics to approximate an isomorphism matcher for finding similar sub-graphs.
