Title: REAL TIME MAPPING OF USER MODELS TO AN INVERTED DATA INDEX FOR RETRIEVAL, FILTERING AND RECOMMENDATION
Abstract:
A catalog record is bridged to information stored in at least one inverted index by receiving an application user interface call associated with a predetermined filter request including a record identifier identifying a record in a relational database. A bitset is generated based on item identifiers in the record. The bitset is applied to at least one inverted index to obtain metadata associated with the item identifiers.
