Abstract: Provided are a computer program product, system, and method for generating a plurality of document plans to generate questions from source text. The declarative source text is processed to generate a plurality of document plan data structures. To generate each document plan data structure, at least a portion of the declarative source text is included in the document plan data structure. A determination is made of at least one relation of arguments in the declarative source text. The determined at least one relation and the arguments are indicated in the document plan data structure. Entity types of the arguments are determined and indicated in the document plan data structure. A natural language generation module processes each of the document plan data structures to generate a plurality of questions, which are stored with the declarative source text.

Abstract: A system for engaging in a recommendation-dialog with a user includes a memory having instructions therein. The system also includes at least one processor in communication with the memory. The at least one processor is configured to execute the instructions to access a recommendation domain, use a structure-mapping technique to generate a data structure based on source material from the recommendation domain, use semantic analyses to generate an ontology based on the data structure and the recommendation domain, generate recommendation-dialog queries based on properties of the data structure, generate a dialog tree based on the ontology and the recommendation-dialog queries, receive a recommendation dialog input, navigate the dialog tree to determine a recommendation, and provide the recommendation to the user.
