This extension provides automated and semi-automated methods for data augmentation, which includes data search, attribute discovery and integration of new attributes to a data set.

The extension provides i) Single-attribute data augmentation, also called as Constrained augmentation or governed data discovery. This discovers a specific attribute as dictated by the user from a given corpus and ii) Multi-attribute data augmentation, also called as Unconstrained augmentation. This discovers relevant attribute from the corpus and augments these to the given data set.

Currently, the extension provides the following operators:

• Legacy: Some of the operators are now considerd as legacy and are replaced by other operators to make the extension more independent of any Backend search server. These include:
  • Data Search
  • Fuse
  • Correlation-Based Search
  • Unconstrained Search

• Single Attribute Augmentation: This group includes operators that work together in a single operator chain.
  • Create Correspondences
  • Translate
  • Advanced Fuse

• Multi Attribute Augmentation
  • Enrich Table by Data Fusion

• Repository Management: This group contains operators for creating repositories and uploading data in them. Currently, you may setup an instance of data search server (developed by University of Mannheinm) on your premise.
  • Create Repository
  • Data Table Upload
  • Data Tables Upload

• Data Table Search: This group provides access to search engines.
  • Google Table Search

Version 2.1.0 (26-04-2019)

• Two bugfixes in Enrich Table by Data Fusion operator.
• A parameter added in Enrich Table by Data Fusion to balance coverage with precision.
• A new dataset, a tutorial process and application template added for fully automated augmentation.

Version 2.0.0 (16-11-2018)

• New operator Create Correspondences. This operator implements Constrained Data Augmentation algorithm without depending on Mannheim data search server.

• Rearranged operators into new operator groups (Legacy, Single Attribute Augmentation and Multi Attribute Augmentation).

Version 1.0.1 (30-07-2018)

• New operator Enrich Table by Data Fusion. This operator implements Unconstrained Data Augmentation algorithm without depending on Mannheim data search server.

• New operator Unconstrained Search. This operator depends on Mannheim data search server.

• New operator Correlation-Based Search. This operator depends on Mannheim data search server.

Version 0.2.0 (30-01-2018)

• New component Connection Manager added to easily maintain connections with multiple instances or endpoints of data search server.

• Repository Management operator group added with following new operators to create repository and upload data:
  • Create Repository
  • Data Table Upload 
  • Data Tables Upload

Version 0.1.3 (19-10-2017)
