Today, there are many web sites that provide information questions - Answers the most asked or called FAQ (Frequency Answer Question). so that users are able to search and view questions - answers that others have asked. And due to the retention question - answer will most likely be stored in the database and search for questions and answers, the user will have a search yourself. Or use the search words must be in the form of a keyword (keyword). If the keywords the user entered did not match the key words in the depots question -answer is not to display questions - answers that the user wants, even if the keywords entered by the user will have the same meaning to the words. Other important issues are in question - the answer. Therefore, this project is developing Semantic Search system for question and answer from FAQ database by applying semantic web technologies to convey meaning or semantic web allows the system to search for questions - the answers easily. In addition, the user can use keywords to search questions already. It can also be searched in the form of a sentence as well. The system can determine the relationship of keywords to other words with the same meaning. Or in the form of a sentence has a meaning consistent. To get the answer that corresponds to the user to ask the most. This will allow users to reduce the time to search and allows to search effectively match the needs of the user
