This paper aims at stating the main advantages and implications of Web 2.0 by analysing popular social networks in Portugal and addressing some examples of their utility. The authors present results of an empirical study applied to young people, aged between 12 and 20 years old, in a specific Portuguese region. In the first part of the study, main characteristics and differences between Web 1.0...

This paper addresses culturally rooted factors within web design and how their theoretical study must affect the design process. We describe and relate theories that have developed over a period of 20 years, traceable in the published literature. We follow the links that connect them in the study of cultural and cognitive aspects in web design and how they finally converge in practical recommen...

We describe a shared task on parsing web text from the Google Web Treebank. Participants were to build a single parsing system that is robust to domain changes and can handle noisy text that is commonly encountered on the web. There was a constituency and a dependency parsing track and 11 sites submitted a total of 20 systems. System combination approaches achieved the best results, however, fa...

We present in this paper a new network storage channel WebShare that uses the plentiful, public Web counters for storage. Therefore, the physical locations of the WebShare encoder and decoder are not restricted to a single path. To make WebShare practical, we have addressed a number of thorny issues, such as the “noise” introduced by other legitimate Web requests, and synchronization between en...

Web-scale data has been used in a diverse range of language research. Most of this research has used web counts for only short, fixed spans of context. We present a unified view of using web counts for lexical disambiguation. Unlike previous approaches, our supervised and unsupervised systems combine information from multiple and overlapping segments of context. On the tasks of preposition sele...

One of the first discussions about a Web enriched with semantics and its relationships with artificial intelligence (and hence, with intelligent agents) dates back to 1998 [4], but it was only ten years ago that the idea of a Semantic Web on top of which agent-based computing would have allowed computer programs to interact with non-local web-based resources, became familiar to a wide audience ...
