An alternative to content based search such as that offered by Google, is faceted search which provides users with multiple directories (facets) to support top-down navigation through a corpus. While this approach is not workable on the open web because of the absence of consistent meta-data, it is applicable to large curated corpora.

This talk will present a faceted search system that has been integrated with a content-based search engine to support high recall queries that can return many relevant results. The system provides aggregated landscapes for facets onto which individual search results are rendered, allowing clusters and result outlier features to be seen. This is supported for both ordinal and categorical facets. The talk will cover the visualisation design, system architecture and a demonstration. The system can also be used for traditional OLAP data such as sales data, where search results are replaced by some ranking of individual sales. This will also be demonstrated.

The talk is based on a demonstration given recently at this years ACM SIGMOD in Indiana.
