Query-By-Example (QBE) [PDF]

open access: possible, 1998
Data Query Languages were developed in the early seventies when the man-machine interface was, by today’s standards, limited and rudimentary. In particular, interaction with the computer was through the processing of batched jobs, where jobs (computation requests such as “run this program on that data”, “evaluate this database query”, etc) were ...

Semantic queries by example

Proceedings of the 16th International Conference on Extending Database Technology, 2013
With the ever increasing quantities of electronic data, there is a growing need to make sense out of the data. Many advanced database applications are beginning to support this need by integrating domain knowledge encoded as ontologies into queries over relational data.

XML QUERY BY EXAMPLE

International Journal of Computational Intelligence and Applications, 2002
XML's tree structure provides a rich background for complicated structural searches. In this paper we present a new system, called XML Query by Example (XML QBE) that allows the user to query XML documents exploiting their inherent tree structure. We present some interesting queries and describe the underlying query processing algorithms.

Query By Example [PDF]

open access: possible, 1990
In diesem Kapitel lernen Sie die Abfragesprache Query By Example kennen. Es zeigt, wie Sie Daten nach verschiedenen Kriterien auswahlen, mit Datenbankfeldern rechnen und die Daten statistisch auswerten konnen. Zudem lernen Sie, mehrere Datenbankdateien miteinander zu verknupfen und abzufragen.

Query from examples [PDF]

open access: possibleProceedings of the VLDB Endowment, 2015
In this paper, we propose a new approach, called Query from Examples (QFE), to help non-expert database users construct SQL queries. Our approach, which is designed for users who might be unfamiliar with SQL, only requires that the user is able to determine whether a given output table is the result of his or her intended query on a given ...

Query by example for web services

Proceedings of the 2008 ACM symposium on Applied computing, 2008
Web services have acquired enormous popularity among software developers and researchers due to the increasing levels of flexibility required by current distributed applications. However, service search facilities are still rather difficult to use. This paper presents WSQBE, a search method that aims at assisting service discoverers by generating a ...

A psychological study of query by example

Proceedings of the May 19-22, 1975, national computer conference and exposition on - AFIPS '75, 1975
Many different query systems have been proposed. One way to partition extant and hypothetical query systems is on the basis of how English-like they are. One approach for an easy-to-use query system is to allow the user to state a question in natural English. The system may then disambiguate the possible interpretations of this question on the basis of

A Pictorial Query-By-Example Language

Journal of Visual Languages & Computing, 1995
Abstract A symbolic image is an array representing a set of objects and a set of spatial relations among them. Symbolic images and related structures have been used in a number of applications including image databases, spatial reasoning, path planning and spatial pattern matching.

Query by Semantic Example

2006
A solution to the problem of image retrieval based on query-by-semantic-example (QBSE) is presented. QBSE extends the idea of query-by-example to the domain of semantic image representations. A semantic vocabulary is first defined, and a semantic retrieval system is trained to label each image with the posterior probability of appearance of each ...

GuessXQ

2013
XML is a widely used general-purpose annotation formalism for creating custom markup languages. XML annotations give structure to plain documents to interpret their content. To extract information from XML documents XPath and XQuery languages can be used. However, the learning of these dialects requires a considerable effort.
