Vector Query with Signature Filtering

Original language description

In recent years, many approaches to filter documents before query evaluation were adopted for optimising query processing over a text data collection. We investigate a mixture of signatures and vector querying in our approach. We present a number of approaches of filtration before the vector query execution. We use the concept of weight-partitioned signature files and propose an efficient method for signature file traversal by S-trees. We verified experimentally that usage of S-trees leads to the decreased number of signature comparisons. The experiments have been done on real text collections.
