Abstract:
This paper describes the theoretical overview of the question-answering systems and knowledge base and representation. Within a joint project with the Information Society Development Institute (ISDI), a question-answering system for Romanian speakers is being developed. The document collection that was provided by ISDI serves as basis for the extraction of questions. The questions are thereafter classified according to the question types and thoroughly analyzed in order to generate the rules for the informal formalism of the knowledge representation process, enabling the system to retrieve the required information.
