Recent advancements in several fields have led to exponential growth of data, commonly known as Big data. However, such vast amount of data is meaningful only when effective techniques for retrieving the data are available. Modern search engines do not use natural language and hence, only provide a large number of documents which significantly increases the user overhead in searching the documents. To address this challenge, question answering systems are used. This chapter discusses the recent advancements made in the field of question answering systems, their working, challenges and future trends.
