In this paper, we present HYSSOP, a system that generates natural language hypertext summaries of insights resulting from a knowledge discovery process. We discuss the synergy between the two technologies underlying HYSSOP: Natural Language Generation (NLG) and Knowledge Discovery in Databases (KDD). We first highlight the advantages of natural language(More)
Computerized analysis of a concept map (CM) syntactic and semantic characteristics can become a complex task, whose results can be doubtful if the map contains either graphical or textual ambiguities. In the specific case of using CMs in education, the use of the results of automatic structural analysis of a map in learning assessment implies the existence(More)
We present a new approach to content determination and content organization in the context of natural language generation for quantitative database summaries. Three key properties make our work innovative and interesting: (1) we developed a new text planning approach to deals with the content organization of a data set into a summary report, for example a(More)
We present a new approach to paratactic content aggregation in the context of generating hypertext summaries of OLAP and data mining discoveries. Two key properties make this approach innovative and interesting: (1) it encapsulates aggregation inside the sentence planning component, and (2) it relies on a domain independent algorithm working on a data(More)
This paper presents the integration of a viewer and simulator of programs into an environment learning to support learning programming in initial classes of Engineering, Computing and Information Systems Courses. The integration proposed was based on a redesign of the architectureto combine resources avaliable in learning environment with an automatic(More)
This paper presents research of an application of a latent semantic analysis (LSA) model for the automatic evaluation of short answers (25 to 70 words) to open-ended questions. In order to reach a viable application of this LSA model, the research goals were as follows: (1) to develop robustness, (2) to increase accuracy, and (3) to widen portability. The(More)
Componentization is a Software Engineering (SE) strategy successfull in the development of new projects. Mainstream games use components that handle a set of functions relevant to a common aspect of a genre (e.g. real time strategy, first person shooter). However, Artificial Intelligence (AI) components, in spite of their great gameplay weight in current(More)
