2. Exploratory search, defined as the situation in which the user starts from a not-so-well-defined information need and progressively discovers more on his need and on the available information to address it, with a mix of lookup, browsing, analysis, and exploration.

3. In this paper, we describe a general-purpose framework for exploratory search.
We focus upon exploratory search in the context of multi-domain queries.
We provide a formalization of exploratory search sessions through a SQL-like query language and protocol, namely SeCoQL.

5. use case: Organize a night out in Milan, by finding a good recent movie in a theater close to the city center and an high-quality restaurant nearby.

7. Evaluation Behavioral model of exploration
model users’ mental phases (Initialization; Selection; Exploration; Formulation; Collection)

8. Evaluation Procedure Pre-experiment questionnaire Video tutorial
Given search problems; user solved them.
Post-experiment questionnaire

9. 1.Evaluates the performance of our system
Relevance of mental phases
Mono- versus multi-domain search
Richness of data visualization

10. 2.Comparison with alternative exploratory systems
