Formulating complex queries is hard, especially in heterogeneous information environments, where users do not understand all the data structures of multiple complex knowledge bases. We see a gap between semantic search tools that are user friendly, but have restricted functionality, and powerful, formal query languages, which are unsuitable for end users. We explore the complexity of semantic queries through an example. Building on this example, we propose a solution using a component based approach. We propose a layered architecture, with components taking an intermediary role between the end user interface and formal query languages. The kinds of components that would be needed for such a system are outlined, and challenges for the system are discussed, in particular, how to combine semantic searches. This paper was presented at EKAW 2006.
