Recent work in Question Answering has focused on web-based systems that extract a correct answers using by simple patterns or short transformation. One of the challenges is the potential mismatch between the expressions in questions and the expressions in text. After the analysis of user question query sentence, these systems searched by various methods using the keyword-based search techniques on the Web. This paper introduces a method of user query paraphrase to find sentence(s) that containing the correct answers to a given natural language question on the web. We present a method for specific modification that is made to convert user question into useful query (or query phrase) for the traditional web search engines by using the query type extraction and the query paraphrase.
