2. Context The Web is a huge, heterogeneousdata source: Unstructured information Structured and semi-structured data Linked Data Documents are integrated with semi-structured or structured data and enriched with semantics Search as a service Google, Yahoo, Amazon, Twitter, YouTube, MySpace, and Facebook Viability of systems based upon search service orchestration
3. Problem Statement Web queries get increasingly complexand specialized as the searcher’s expertise grows Exploratory search Multi-step search processes From document searchto object/entity search Multi-domain queries multiple semantic fields of interest (e.g., travels, music, shows, food, movies, health, genetic diseases, etc.) domain-specific (aka, vertical) search engines provide more focused results than general-purpose ones the challenge is to match the results coming fromdifferentverticals

complex search is characterized by: multiple searches, possibly over multiple sessions and spanning multiple sources of information; a combination of exploration and more directed information finding activities; the need of note-taking, the variation of the search goal during the search process.
