Metadata search based on semantics
View Patent ↗According to some embodiments, a method and an apparatus of enriching search results with metadata are provided to receive a plurality of metadata associated with an entity and storing the plurality of metadata in a repository. A search request associated with the entity is received and search results that comprise a portion of the plurality of metadata stored in the repository are determined.
1. A method to enrich search results with metadata, the method comprising:
receiving a plurality of metadata based on a lineage relationship and an impact relationship associated with an entity;
storing the plurality of metadata in a repository;
receiving a search request associated with the entity; and
determining search results that comprise a portion of the plurality of metadata stored in the repository, where the portion of the plurality of metadata that is transmitted is based on a score calculation associated with score

wherein t is a term, q is a query, tf is a frequency of the term t, d is a document, depth (n th ) is a level of depth of an object to a top object, p is a parent, relationshipf(t,d ) is a relationship of the document, and idf is an inverse document frequency of the term.
2. The method of claim 1 , wherein the plurality of metadata are received from a metadata engine.
3. The method of claim 1 , wherein the plurality of metadata comprise entities such as a report, a report field, a database column, and a database table.
4. A non-transitory computer-readable medium comprising instructions that when executed by a processor perform a method to enrich search results with metadata, the method comprising:
receiving a plurality of metadata based on a lineage relationship and an impact relationship associated with an entity;
storing the plurality of metadata in a repository;
receiving a search request associated with the entity; and
determining search results that comprise a portion of the plurality of metadata stored in the repository, where the portion of the plurality of metadata that is transmitted is based on a score calculation associated with score

8. The apparatus of claim 7 , wherein the plurality of metadata comprise entities such as a report, a report field, a database column, and a database table.
9. The method of claim 1 , wherein the entity is a target entity and the metadata is associated with the entity being affected when a change is made to a source entity.
10. The method of claim 9 , wherein the target entity resides in a first system and the source entity resides in a second system.
11. The method of claim 1 , wherein the entity is a source entity and the metadata is associated with a change to the entity that affects a target entity.
12. The method of claim 11 , wherein the target entity resides in a first system and the source entity resides in a second system.
