Abstract: Question answering system is one of sub-fields information retrieval that integrates information from multiple sources as document collection whether local or web to provide concise answer to specific question which is entered by the user. This question answering system is about history of Khulafaur Rasyidin which is expanded from another researcher with adding types of question word; such as: “what, why, and how”. So, this question answering system provides question words: ”who, when, and where” as factoid question and “what, why, and how” as non-factoid question. This question answering system consists of several processes: question analyzer, document retrieval, and answer extraction. The question analyzer aims to classify question to obtain answer type, clue word, and query. Answer extraction for factoid question is performed by calculating distance between answer candidate to all queries from the question in sentence answer and for non-factoid question is performed by sentence pattern which has priority value for each sentence. System testing is performed by giving 30 question words for factoid question and non-factoid question. The evaluation of answer result refers to another researcher which has 5 categories, namely:” true, inappropriate, not supportive, unanswered, and wrong”. The result of the system evaluation shown factoid question has high performance to obtain exact answer and non-factoid question has low performance.
