GeoCLEF Text Retrieval and Manual Expansion Approaches

In this paper we will describe the Berkeley approaches to the GeoCLEF tasks for CLEF 2006. This year we used two separate systems for different tasks. Although of the systems both use versions of the same primary retrieval algorithm they differ in the supporting text pre-processing tools used.
