Claim 11

The system of claim 1, wherein a topical search, responsive to the query, comprises a content-based similarity search where the query does not define a precise set of objects, the search engine computing the similarity of the query to each object in the database to generate a ranked list of objects ordered by relevance to the query.

Claim 12

The system of claim 1, wherein said objects comprise data objects, and said data objects are stored in a database with relationships defined between the objects, said hierarchical view generator selecting and processing the relationships to identify structurally relevant parents from an original child set.

Claim 13

The system of claim 1, wherein said hierarchical view generator includes an iterator, said iterator processing structural relationships to build a parent hierarchy based on topical and structural relevance, said iterator selecting structural relationships in a query context and ranks parent objects based on their structural relevance to the query.

Claim 14

The system of claim 1, wherein the hierarchical structure groups objects for answering a user's query, and provides insight into the relevant structure of the database, to satisfy the user's information need.

Claim 15

The system of claim 1, wherein the user's query selects certain relationships for finding structurally relevant objects and for organizing and displaying the result list accordingly, wherein said objects are ranked based on degrees of topical relevance, and a subset of the topically relevant objects is selected for further relationship processing.

Claim 16

The system of claim 1, wherein said objects on the result list are organized based on their structural relationships, and display of objects at certain levels of the hierarchy is suppressed based on the relationships in which they participate, wherein objects in the topically relevant set are ranked, and the children thereof are organized under their parents according to a structural relationship.

Claim 17

Claim 21

Claim 22
