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 unsuit-able 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 inter-face 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.
