Abstract
Data scientists spent 80–90% of their efforts in data integration and there is still no end-to-end automatic integration and wrangling pipeline working for a large number of data sources. This work proposes a data integration system that transforms fast-evolving raw data sources to user desired tables. Based on a set of pre-trained models, a user only needs to specify the schema of the outcome feature vector as well as a few examples of rows, the system will automatically generate the outcome table from the raw data sources. The training process is automatically injected with provisioned schema evolution so that the model is resistant to data source changes. Our experiments show that the proposed approach is particularly effective for the integration of data with fast evolving schemas.
