Dynamic Queries for Information Exploration: An Implementation and Evaluation

by Christopher Ahlberg, Christopher Williamson, Ben Shneiderman , 1992
"... We designed, implemented and evaluated a new concept for direct manipulation of databases, called dynamic queries, that allows users to formulate queries with graphical widgets, such as sliders. By providing a graphical visualization of the database and search results, users can find trends and exce ..."

The Lumière Project: Bayesian User Modeling for Inferring the Goals and Needs of Software Users

by Eric Horvitz, Jack Breese, David Heckerman, David Hovel, Koos Rommelse - In Proceedings of the Fourteenth Conference on Uncertainty in Artificial Intelligence , 1998
"... The Lumi`ere Project centers on harnessing probability and utility to provide assistance to computer software users. We review work on Bayesian user models that can be employed to infer a user's needs by considering a user's background, actions, and queries. Several problems were tackled i ..."

Online Aggregation

by Joseph M. Hellerstein, Peter J. Haas, Helen J. Wang , 1997
"... Aggregation in traditional database systems is performed in batch mode: a query is submitted, the system processes a large volume of data over a long period of time, and, eventually, the final answer is returned. This archaic approach is frustrating to users and has been abandoned in most other area ..."

areas of computing. In this paper we propose a new online aggregation interface that permits users to both observe the progress of their aggregation queries and control execution on the fly. After outlining usability and performance requirements for a system supporting online aggregation, we present a

Faceted metadata for image search and browsing

by Ka-ping Yee, Kirsten Swearingen, Kevin Li, Marti Hearst - In ACM Conference on Computer-Human Interaction , 2003
"... There are currently two dominant interface types for searching and browsing large image collections: keyword-based search, and searching by overall similarity to sample images. This paper presents an alternative in which users are able to navigate explicitly along conceptual dimensions that describe ..."

that describe the images. The interface makes use of hierarchical faceted metadata and dynamically generated query previews. A usability study, conducted with 32 art history students exploring a collection of 35,000 fine arts images, compares this approach to a standard image search interface. Despite

RQL: A Declarative Query Language for RDF

by Greg Karvounarakis, Sofia Alexaki, Vassilis Christophides, Dimitris Plexousakis, Michel Scholl
"... Real-scale Semantic Web applications, such as Web Portals and E-Marketplaces, require the management of voluminous metadata repositories containing descriptive information (i.e., metadata) about the available Web resources and services. Better knowledge about the meaning, usage, accessibility or qua ..."

are already appearing (e.g., as exported Portal catalogs or service descriptions), sufficiently expressive declarative languages for querying both RDF descriptions and schemas are still missing. In this paper, we propose RQL, a new RDF query language, relying on a formal graph model that permits

Dynamic Queries for Visual Information Seeking

by Ben Shneiderman - IEEE Software , 1994
"... Dynamic queries are a novel approach to information seeking that may enable users to cope with information overload. They allow users to see an overview of the database, rapidly (100 msec updates) explore and conveniently filter out unwanted information. Users fly through information spaces by incre ..."

Freebase: a collaboratively created graph database for structuring human knowledge

by Kurt Bollacker, Colin Evans, Praveen Paritosh, Tim Sturge, Jamie Taylor - In SIGMOD Conference , 2008
"... Freebase is a practical, scalable tuple database used to struc-ture general human knowledge. The data in Freebase is collaboratively created, structured, and maintained. Free-base currently contains more than 125,000,000 tuples, more than 4000 types, and more than 7000 properties. Public read/write ..."
Abstract - Cited by 338 (1 self) - Add to MetaCart
/write access to Freebase is allowed through an HTTP-based graph-query API using the Metaweb Query Language (MQL) as a data query and manipulation language. MQL provides an easy-to-use object-oriented interface to the tuple data in Freebase and is designed to facilitate the creation of collaborative, Web

Optimizing Queries across Diverse Data Sources

by Laura M. Haas, Donald Kossmann, Edward L. Wimmers, Jun Yang - In Proc. of VLDB , 1997
"... Businesses today need to interrelate data stored in diverse systems with differing capabilities, ideally via a single high-level query interface. We present the design of a query optimizer for Gar- lic [C+95], a middleware system designed to integrate data from a broad range of data sources with ver ..."

Lore: A database management system for semistructured data

by Jason McHugh, Serge Abiteboul, Roy Goldman, Dallan Quass, Jennifer Widom - SIGMOD Record , 1997

Implementing Lore has required rethinking all aspects of a DBMS, including storage management, indexing, query processing and optimization, and user interfaces. This paper provides an ov ..."

Querying the World Wide Web

by Alberto O. Mendelzon, George A. Mihaila, Tova Milo , 1997
"... The World Wide Web is a large, heterogeneous, distributed collection of documents connected by hypertext links. The most common technology currently used for searching the Web depends on sending information retrieval requests to "index servers" that index as many documents as they can find ..."

One problem with this is that users must be aware of the various index servers (over a dozen of them are currently deployed on the Web), of their strengths and weaknesses, and of the peculiarities of their query interfaces. A more serious problem is that these queries
