Query by Image and Video Content: The QBIC System
Computer, 1995Research on ways to extend and improve query methods for image databases is widespread. We have developed the QBIC (Query by Image Content) system to explore content-based retrieval methods. QBIC allows queries on large image and video databases based on

A multimedia query specification language
Proceedings. International Workshop on Multi-Media Database Management Systems, 1996Typically, multimedia applications involve thousands of hours of video, images, audio, text and graphics that need to be stored, retrieved and manipulated in a large multimedia database. There is therefore an important need for novel techniques and systems which provide an efficient retrieval facility of the voluminous information stored in the ...

Natural English as a query language offers the ultimate in directness for man-machine communications and has new and powerful potentials for interactive problem solving. The linguistic problems underlying machine interpretation and generation of natural English, however, have been slow in yielding to solution, though recent successes have raised new ...

The Constellation Query Language [PDF]
, 2009 Collaboration in modeling is essential to success, but ORM diagrams intimidate many business people, and most would never install an ORM modeling tool on their computers. The Constellation Query Language (CQL) offers an alternative able to represent almost any ORM2 model in plain text using natural language, with the goal of supporting involvement ...

HyQ, the HyTime query language, provides the answer to situations where you need to specify hyperlinks to locations that may change over time or where a compact notation is preferable to a long location ladder. HyQ queries are similar to database queries, except that they have special facilities for dealing effectively with hierarchical structures like

When storing data in heterogeneous databases, one of the top-down design issues concerns the usage of multiple query languages. A common language enables querying of database schemas in a platform independent format. This is particularly useful in federated database systems when newly added databases may be both numerous and heterogeneous.

Journal of Visual Languages & Computing, 1991
A graphical query language is a visual language which is intended as a database interface and which employs visual metaphors in order to express the semantics of a database language. The TableTalk graphical query language assumes an objectoriented data model and is based upon the notion of a functional query language.

We investigate the expressive power of query languages with counting ability. We define a LOGSPACE extension of first order logic and a PTIME extension of fixpoint logic with counters. We develop specific techniques, such as games, for dealing with languages with counters and therefore integers. We prove in particular that the arity of the tuples which
