Abstract

The present invention discloses a data extraction method and apparatus, relates to the field of data processing, and solves the problem that the efficiency for manually extracting data is low. The method comprises: pre-processing the data to acquire first data in the front and second data in the back; calculating the similarity between the first data and the second data; if the similarity between the first data and the second data meets a preset similarity threshold value, deleting the second data in the back; and keeping the first data in the front to obtain summary information. The data extraction method and apparatus are suitable for being applied to a process of extracting a large amount of festival data with different formats.

Description

technical field [0001] The invention relates to the field of data processing, in particular to a data extraction method and device. Background technique [0002] Nowadays, there are many types of data. In the process of digital processing of data, various types of data can be collected. There are many ways to record and collect a certain type of event or phenomenon, such as text description, camera photography, shooting, telephone recording , SMS, WeChat, blog, email, TV station, radio station, etc. Among these data, there are characteristics such as diverse data types, diverse data sources, complex data structures, and huge data capacity. [0003] Faced with these diverse and huge amounts of data, if some kind of data extraction or data statistics is required, the current mainstream processing idea is to compare the data similarity and select one of the data that is too similar or even identical. Retain and eliminate duplicate data to achieve the purpose of data deduplica...
