Abstract

Few if any Information Retrieval (IR) systems have had to deal with Concurrency Control (CC) on inverted files. In order to examine the issues involved in CC on inverted files, the effects of various operations (e.g. Boolean) on the effectiveness of the IR system are examined using the example of interleaved transactions. Solutions to the problems identified are examined by discussing the three main CC mechanisms; Locking, Optimistic CC and Timestamp Ordering. The effect of delays and document availability are examined. The problem of stored sets is identified. The need for further work in the area is identified.
