Efficient indexing of error tolerant set containment

摘要

The claimed subject matter provides a method and a system for the efficient indexing of error tolerant set containment. An exemplary method comprises obtaining a frequency threshold and a query set. All tokens or token sets within the query set are determined, and then all minimal infrequent tokens or all minimal infrequent tokens sets of data records are found and used to build an index. The minimal infrequent tokens or minimal infrequent tokensets are processed in a fixed order, and then a collection of signatures for each minimal infrequent token or token set is determined.
