Methods and systems for searching over a large corpus of data to discover relevant information artifacts based on similar content and/or relationships are disclosed. Improvements over simple keyword and phrase based searching over Internet scale data are shown. A search query may be modified or relaxed based on the search terms and a contextual relationship therebetween. The search results may be ranked based on both a data ranking corresponding to the data entries in the corpus and a query ranking corresponding to the search query and/or the modified or relaxed search query. In this manner, the accuracy and relevance of the search results is improved.

Embodiments of the present invention provide systems and methods for relationship discovery. According to one embodiment of the present invention, arbitrarily complex relationship discovery rules can be applied to components in a data model to determine if a relationship exists between the components. If the components satisfy a relationship discovery rule, a relationship can be established for the components. Because the relationships are established based on the application of relationship discovery rules rather than through enforcement of a database schema, new relationships and relationship types can be established without having to alter the underlying database schema. Additionally, because rules can be repetitively applied, relationships can be established, deleted and updated as the system being modeled changes.
