2020-7-13 · Data transformation is also known as ETL (Extract, Transform, Load), which sums up the steps involved in transforming data. As per ETL, the data is first extracted from multiple sources, transformed into a required format, and then loaded into a data warehouse for powering analysis and reporting processes. DataChannel offers a data integration ...
Text mining usually deals with texts whose function is the communication of actual information or opinions, and the stimuli for trying to extract information from such text automatically is compelling—even if success is only partial. Text mining, using manual techniques, was used first during the 1980s [7].
