Query by Example Methods for Audio Signals
Proceedings of the 7th Nordic Signal Processing Symposium - NORSIG 2006, 2006Various methods for query by example for audio signals are discussed in this paper. The query by example aims at automatic retrieval of audio excerpts similar to a user-provided audio sample from his/her personal audio database. Methods based on hidden Markov models, feature histograms, and likelihood ratio test are discussed.

Privacy-preserving Query-by-Example Speech Search
2015 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2015This paper investigates a new privacy-preserving paradigm for the task of Query-by-Example Speech Search using Secure Binary Embeddings, a hashing method that converts vector data to bit strings through a combination of random projections followed by banded quantization.

Query by Example for Cross-Lingual Event Retrieval
Proceedings of the 43rd International ACM SIGIR Conference on Research and Development in Information Retrieval, 2020We propose a Query by Example (QBE) setting for cross-lingual event retrieval. In this setting, a user describes a query event using example sentences in one language, and a retrieval system returns a ranked list of sentences that describe the query event, but from a corpus in a different language.

Ontology-Schema Based Query by Example
2019The Web has evolved from a network of linked documents to one where both documents and data are linked, resulting in what is commonly known as the Web of Linked Data, that includes a large variety of data usually published in RDF from multiple domains. Intuitive ways of accessing RDF data become increasingly important since the standard approach would ...

Query by example for nested tables
1998QBEN, a Query By Example language for Nested tables, is described. QBEN is user-friendly and allows for the easy formulation of complex queries. At the same time, optimization techniques can be incorporated that enable the global optimization of a series of queries. QBEN is addressed both to non-experts and experts.

Object Oriented XML Query by Example
2003This paper describes an XML query language called XML-QBE, which can be used to both query and update XML documents and databases. The language itself has a simple XML form, and uses a query by example paradigm. This language was designed as a middleware layer between UML data models and backend database schemas, as part of a solution to the ...

Color co-occurrence descriptors for querying-by-example
Proceedings 1998 MultiMedia Modeling. MMM'98 (Cat. No.98EX200), 1998Multimedia documents are different from traditional text documents, because they may contain encodings of raw sensorical data. This fact has severe consequences for the efficient indexing and retrieval of information from documents in large unstructured collections (e.g. WWW), because it is very difficult to automatically identify generic meanings from

Query-by-Example: A data base language
IBM Systems Journal, 1977Discussed is a high-level data base management language that provides the user with a convenient and unified interface to query, update, define, and control a data base. When the user performs an operation against the data base, he fills in an example of a solution to that operation in skeleton tables that can be associated with actual tables in the

MedlineQBE (Query-by-Example).
Proceedings. AMIA Symposium, 2002Medline has the potential to significantly improve medical care but effective information retrieval remains difficult. Custom interfaces and relevance feedback are two approaches that have been successfully used to improve information retrieval. There are, however, many ways to implement these approaches.

Animate System for Query By Example in Image Database
2005In the last years a great deal of content-based techniques for image indexing and retrieval has been developed. In spite of such important efforts, automatic seeking of images in a very large database is still a challenging task. In this paper we describe a strategy to cope with efficient indexing for query by example processing, which brings together ...
