An embodiment generates, using a trained document embedding model, a plurality of table embeddings, each table embedding in the plurality of table embeddings representing a table in a dataset. An embodiment generates, using the trained document embedding model, a query embedding, the query embedding representing a natural language query regarding the dataset. An embodiment identifies a set of responsive tables, the set of responsive tables comprising a first table in the dataset, the first table in the dataset represented by a first table embedding, the first table embedding and the query embedding having a similarity score above a similarity score threshold.

Embedding based heterogenous dataset evaluation

This invention relates to a system, method and computer program product for a data warehouse model validation system, said data warehouse model validation system having an ETL model and a corresponding data warehouse model, said data ETL system comprising: an element group locator for locating an element group across the ETL model and the data warehouse model, whereby the element group comprises ETL elements and related data warehouse elements; an inconsistency determiner for determining inconsistencies between the ETL elements and data warehouse elements, whereby one or more elements are missing from the data warehouse model or one or more elements in the data warehouse model do not correspond to expected elements or features of elements; and an inconsistency recorder for recording any located missing elements or unexpected elements from the located element group.

Data warehouse model validation

Techniques are disclosed for managing development of a model set comprised of one or more object models by a plurality of model developers. Each model developer may be considered an interested party. For example, when a model developer changes an area of the model, that person becomes the most interested party in other changes made to the same area. An automated mechanism is provided to track changes made to the model set and informs interested parties as changes are made or after changes are made to the model based on a weighting system. In one embodiment, the weighting system may be based on a distance from the changed portions and on the amount of time since a party last made a change to the same area.
