Abstract:

Provided is a technique for building an index. A new indexis built and an anchor text tableand a duplicates tableare output using a store, a delta store, and previously generated global analysis computations, wherein the previously generated global analysis computationsinclude an anchor text table, a rank table, and a duplicates table. New global analysis computationsare generated using the anchor text tablei+1, the duplicates table, and the previously generated global analysis computations.
