Exploratory search Exploratory search is a specialization of information exploration which represents the activities carried out by searchers who are either: a) unfamiliar with the domain of their goal (i.e. need to learn about the topic in order to understand how to achieve their goal) b) unsure about the ways to achieve their goals (either the technology or the process) c) or even unsure about their goals in the first place.

Exploratory Search in Structured Data: Data Warehouses and OLAP to the Rescue? by Melanie Herschel Data warehouses and online analytical processing (OLAP) Structured data: integrate, data comparison, decision making Limitations: socialization, comprehension and interpretation, and discovery DW & OLAP Exploratory search Discovery cannot go beyond queries that the schema of the data warehouse supports designed to efficiently answer predefined queries not covered by the rigid schema reveal things that users of the system did not think about during design time Adaptation limited capabilities for changing or evolving information needs need to be able to adapt to a new and rapidly changing environment Data and Users NoSQL databases? expert users the masses human-computer interaction will be key to success.

Exploratory Search and Web searching by Yannis Tzitzikas Ranking is not enough. focalized (else called precision-oriented) information needs The majority of information needs are recall-oriented. enable easy access to low ranked hits, allow browsing the relevant hits and resources in groups (according to various criteria), offer overviews (of variable complexity) of the hits, and let the user to restrict gradually the search results. Ubiquity with no predetermined facets Fusion of Structured and Unstructured Content User Control explicit, user-provided, and controllable preference management  Evaluation

Exploratory Search and Multimedia Data by K. Selcuk Candan Challenges Volume, Velocity, and Variety High-dimensional, Multi-modal (temporal, spatial, hierarchical, and graph-structured) Imprecision of the media features and Sparsity of the observations in the real-world.  Systems for multimedia exploration must be able to support, a continuous exploration cycle involving four key steps: sense & integrate filter, rank & recommend visualize & feedback act & adapt Development of integrated data platforms that can support, in an optimized and scalable manner, both media analysis and data manipulation operations.
