ITRI-00-24 Planning texts by constraint satisfaction
نویسنده
چکیده
A method is described by which a rhetorical-structure tree can be realized by a text structure made up of sections, paragraphs, sentences, vertical lists, and other textual patterns, with discourse connectives added (in the correct positions) to mark rhetorical relations. We show that text-structuring can be formulated as a Constraint Satisfaction Problem , so that all solutions respecting constraints on text-structure formation and structural compatibility can be eeciently generated. Of the many solutions generated by this method, some are stylistically preferable to others; we show how further constraints can be applied in order to select the best versions. Finally, we discuss some extensions such as the generation of indented text structures.

ITRI-00-08 An integrated framework for text planning and pronominalisation
This paper describes an implemented system which uses centering theory for planning of coherent texts and choice of referring expressions. We argue that text and sentence planning need to be driven in part by the goal of maintaining referential continuity and thereby facilitating pronoun resolution: obtaining a favourable ordering of clauses, and of arguments within clauses, is likely to increa...

متن کاملITRI - 00 - 19 Using an abstract rhetorical representation to generate a variety of pragmatically congruent texts
In order for a text planner to produce all the possible pragmatically congruent texts and only these, we distinguish between abstract and concrete rhetorical representations of a text. We discuss these representations and present our methodology for exploring the mappings from the underlying message to the actual surface discourse.
متن کاملTask planning for cooperating self-reconfigurable mobile fixtures
The work solves the problem of task and motion planning of a self-reconfigurable fixture system. A feasible solution is a key requirement for the viability of such systems, which have raised hopes of overcoming the deficiencies that more traditional fixtures are recognized to have in the dynamic conditions of modern manufacturing, with its increasing emphasis on flexibility, adaptability, and a...
