Abstract
The system thereof comprises: an entity data analyzing unit coupled to the data source and used for analyzing the entity data in the data resource in order to get the internal semantic structure of each entity data, and to generate a feature set; a data extracting unit used for extracting the reference entity data according to the feature set generated by the entity analyzing unit.
Description
technical field [0001] The present invention relates to the field of data processing. More specifically, the present invention relates to systems and methods for extending reference data. Background technique [0002] Decision support analysis for data warehouses can affect major business decisions. Therefore, the precision of this analysis is very important. However, data received by a data warehouse from outside often includes errors such as spelling mistakes, errors caused by inconsistencies in contracts between data sources, and missing fields. Therefore, it takes a lot of time and expense to perform data cleaning (ie, detect and correct errors in the data). [0003] In this regard, a common technique is to compare incoming data tuples against a reference data lexicon (ie, a relational table) of tuples that are known to be correct. group is standardized. Reference data dictionaries can be the source of a large amount of vocabulary and structure in attribute values. ...
