Abstract
To the standard operations of an inverted index database, a new “To” operator is added. The “To” operator treats the standard single-level linear collection of records as organized into localized clusters. The “To” operator accepts a list of records, each at a same hierarchical level in a cluster, and a specification of a hierarchical level that all the input records should be converted into. The “To” operator outputs a list of records, representing a conversion of the input records to the specified new level. Logical Forms, against which frame extraction rules match, can be stored in hierarchical clusters. A database query can be formulated, that matches against such Logical Forms, that provides the same or similar functionality to a frame extraction rule. Such queries extend the range of applications of a particular inverted index database and/or can aid in the development of new frame extraction rules.
