This paper shows how the framework of Rhetorical Structure Theory (RST) for discourse modelling can be expressed through XML annotations and then used to implement a natural language generation (NLG) system for the web. The system applies simplified RST schemes to the elaboration of a master document in XML from which content segments are chosen to suit the(More)
One of the key objectives of web service technology is to construct processes that enable service providers to interconnect with their clients. The industry has developed the UDDI registry to enable the register of services and to make them available to their users. However, the keyword-based search of UDDI frequently return no results because there is no(More)
The Ubiquitous Web (UW) defines a pervasive web infrastructure where all physical objects are resources accessible by URIs, providing information and services that enrich users' experiences in their physical context. Thus, applying cutting-edge web technologies as middleware infrastructure for intelligent environments may be a good approach to materialize(More)
Context-aware systems allow users to access services and multimedia data according to their current context (location, identity, preferences). Web 2.0 fosters user contribution and presents the web as an application programming platform where third parties can create new applications (mash-ups) mixing the functionality offered by others. We deem that(More)
In this paper we describe an approach to machine translation which involves multilingual text generation via interaction with the user, who is monolingual: the system will work in a specific and fairly restricted domain. Key techniques used include the use of examples rather than linguistic rules to give the equivalents between the languages, and the(More)
The notion of context has been widely studied and there are several authors that have proposed different definitions of context. However, context has not been widely studied in the framework of human mobility and the notion of context has been imported directly from other computing fields without specifically addressing the tourism domain requirements. In(More)
We present an RST-based discourse annotation proposal used in the construction of a trial multilingual XML-tagged corpus of teaching material in Basque, English and Spanish. The corpus feeds an experimental multilingual document generation system for the web. The main contributions of this paper are an implementation of RST through XML metadata and the(More)
Content selection is a key factor of any successful document generation system. This paper shows how a content selection algorithm has been implemented using an efficient combination o f XML/XSL technology and the framework of RST for discourse modeling. The system generates multilingual documents adapted to user profiles in a learning environment for the(More)
