Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 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 ( q , d ) = ∑ t i n q ( tf ( t in d ) 1 / 2 · idf ( t ) 2 · * ( ∑ p i n parents relationshipf ( t , d ) * depth ( n th ) * score ( p ) ) ) 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 ( q , d ) = ∑ t i n q ( tf ( t in
