ULYSSES: A Lattice-Based Multiple Interaction Strategy Retrieval Interface
نویسندگان
چکیده
We present a two-stage system for information exploration and retrieval. The first stage, named GALOIS, organizes the information contained into a database into a particular lattice structure; the second stage, named ULYSSES, is a visual interface to access the structure built in the earlier stage. In this paper we focus on the latter. ULYSSES is based on a tight integration of traditional and novel user interaction paradigms that can be seen as a search&bound approach to information retrieval. The user may search the retrieval space by browsing or querying, but he or she may also bound the retrieval space by specifying constraints that the information contained in it has to satisfy. These interaction modes can be naturally combined to produce a hybrid retrieval strategy that best reflects the user goals and his/her domain knowledge. The retrieval effectiveness of our system has been tested in an experiment on subject searching where i t compared favourably with respect to a Boolean retrieval system.

Hydrodynamic investigation of multiple rising bubbles using lattice Boltzmann method
Hydrodynamics of multiple rising bubbles as a fundamental two-phase phenomenon is studied numerically by lattice Boltzmann method and using Lee two-phase model. Lee model based on Cahn-Hilliard diffuse interface approach uses potential form of intermolecular forces and isotropic finite difference discretization. This approach is able to avoid parasitic currents and leads to a stable procedure t...

متن کاملInformation retrieval through hybrid navigation of lattice representations
In this paper we present a comprehensive approach to automatic organization and hybrid navigation of text databases. An organizing stage first builds a particular lattice representation of the data, through text indexing followed by lattice clustering of the indexed texts. The lattice representation, then, supports the navigation stage of the system, a visual retrieval interface that combines t...
متن کاملA system for conceptual structuring and hybrid navigation of text databases*
We present a three-stage system for information exploration and retrieval. Given a collection of texts, the first stage extracts a set of index terms describing each text. The second stage, named GALOIS, exploits the indices determined in the earlier stage to build a particular lattice of clustered texts. The resulting structure supports the third stage, a visual retrieval interface named ULYSS...
