Research in Knowledge Delivery

This report summarizes the research and development work done over four years toward the goal of automatically planning and generating fluent multisentence paragraphs of English text. The work consisted of three principal components, namely knowledge representation, grammar development, and text structuring. With respect to knowledge representation, a powerful technique of linking the generator with arbitrary applications was developed by using a very general underlying taxonomy of entities in the world and various specific domain-related taxonomies. As part of grammar development, the invertibility of the grammar in use by the project was investigated, with the eventual goal of developing a combined bidirectional parsing-generation system using the same grammar net-work. Finally, a text structure planner was developed and the whole system was successfully used to generate paragraphs in three different application domains.
