What is Restricted-Domain QA Systems

Chapter 25
Handbook of Research on ICTs for Human-Centered Healthcare and Social Care Services
This kind of question answering systems deals with questions under a specific domain, and can be seen as an easier task because natural language processing systems can exploit domain-specific knowledge frequently formalized in ontologies. Alternatively, these systems might refer to a situation where only a limited kind of questions is accepted.

Abstract
Question-Answering Systems (QA Systems) can be viewed as a new alternative to the more familiar Information Retrieval Systems. These systems try to offer detailed, understandable answers to factual questions, in order to retrieve a collection of documents related to a particular search (Jackson & Schilder, 2005). The authors carry out a study to evaluate the quality and efficiency of open- and restricted-domain QA systems as sources for physicians and users in general through one monolingual evaluation and another multilingual. Their objective led them to use definition-type questions in order to evaluate QA systems and determine if they are useful to retrieve medical information. In addition, they analyze and evaluate the results obtained, and identify the source or sources used by the systems and their procedure (Olvera-Lobo & Gutiérrez-Artacho, 2010, 2011).
