This paper firstly introduces the characteristics and structure of Web tables and describes the process of information extraction over Web tables. Then four key technologies are analysed, including Web table detection, Web table structure recognition, Web table interpretation and presentation of table extraction. It also analyses the application of the research and points out the problems in current researches, and finally presents a prospect of its future.

Key wordsWeb tables      Information Extraction      Web Table Detection      Web Table Structure Recognition      Web Table Interpretation
