Text Generation in a Dynamic Hypertext Environment
نویسندگان
چکیده
This paper describes PEBA-II, a working natural language generation system which interactively describes animals in a taxonomic knowledge base via the production of World Wide Web pages. Our aim is to construct a natural language document generation system with real practical applicability: to this end, the system reconstructs and combines a number of existing ideas in the literature in a novel way, and proposes a solution to the problem of breadth of coverage that is based on a pragmatic approach to knowledge representation and linguistic realisation. The system embodies the following features: • a reconstruction of some of the core ideas in schema–based text generation [McKeown 1985], applied to the generation of hypertext documents; • the principled use of a phrasal lexicon to ease surface generation, in concert with a knowledge base whose elements may correspond to pre–compiled collections of atomic units; • a user model and discourse model that permit interesting variations in the texts produced. We describe each of the above aspects of the existing system in some detail, and point to a number of interesting research directions it opens up.

ILEX: an architecture for a dynamic hypertext generation system
Generating text in a hypermedia environment places different demands on a text generation system than occurs in non-interactive environments. This paper describes some of these demands, then shows how the architecture of one text generation system, ILEX, has been shaped by them. The architecture is described in terms of the levels of linguistic representation used, and the processes which map b...

متن کاملSources of Flexibility in Dynamic Hypertext Generation
'Dynamic hypertext ' is hypertext which is automatically generated at the point of need. A number of NLG systems have now been developed to operate within a hypertext environment; and now that these systems are becoming widely available on the World Wide Web, it is useful to take stock of how well-equipped NLG technology is to work in this new domain. A generation system in a hypertext environm...
متن کاملThe TELLTALE Dynamic Hypertext Environment: Approaches to Scalability
Methods and tools for nding documents relevant to a user's needs in document corpora can be found in the information retrieval, library science, and hypertext communities. Typically, these systems provide retrieval capabilities for fairly static corpora, their algorithms are dependent on the language for which they are written, e.g. English, and they don't perform well when presented with missp...
