Research Status and Prospect of Data Extraction and Cleaning Technology in Large Environment

Abstract

In the era of big data, how to get effective data from the massive data, the data obtained by the relevant analysis and processing is particularly important. This paper first introduces the importance of data cleaning and data extraction technology, secondly from different angles, introduced the two technology, and then summarizes the current domestic and international data cleaning and data extraction technology research, and finally describes the data extraction and data cleaning technology development prospects. It has a certain guiding role in the research of data extraction and cleaning technology in the future.
