Question Answering (QA) system is a field of Natural language processing, which allows users to ask questions using the natural language sentence and return a brief answer to the users rather than a list of documents. One type of QA systems is Temporal Question Answering system. Time is an important dimension in any information system. Time- specific information embedded in document in the form of temporal expressions. Temporal expressions are words or phrases that describe a point, duration in time. Extraction of these expressions from raw text is used for a wide range of information retrieval tasks such as Summarization, Question Answering and other tasks. In this paper we give a survey of Temporal Question Answering system which focuses on answering temporal questions posted by humans in natural language.
