Query-by-Example Music Information Retrieval by Score-Informed Source Separation and Remixing Technologies

open access: yesEURASIP Journal on Advances in Signal Processing, 2010
We describe a novel query-by-example (QBE) approach in music information retrieval that allows a user to customize query examples by directly modifying the volume of different instrument parts.

Fuzzy query by example

open access: yesProceedings of the 33rd Annual ACM Symposium on Applied Computing, 2018
This paper describes Fuzzy Query By Example, an approach helping users retrieve data without any prior knowledge of the database schema or any formal querying language. The user is solicited to evaluate, in a binary way, pre-selected items of the database.

Separations in Query Complexity Based on Pointer Functions [PDF]

open access: yes, 2015
In 1986, Saks and Wigderson conjectured that the largest separation between deterministic and zero-error randomized query complexity for a total boolean function is given by the function $f$ on $n=2^k$ bits defined by a complete binary tree of NAND gates

Search on speech from spoken queries: the Multi-domain International ALBAYZIN 2018 Query-by-Example Spoken Term Detection Evaluation

open access: yesEURASIP Journal on Audio, Speech, and Music Processing, 2019
The huge amount of information stored in audio and video repositories makes search on speech (SoS) a priority area nowadays. Within SoS, Query-by-Example Spoken Term Detection (QbE STD) aims to retrieve data from a speech repository given a spoken query.

Performance of Graph and Relational Databases in Complex Queries

open access: yesApplied Sciences, 2022
In developing NoSQL databases, a major motivation is to achieve better efficient query performance compared with relational databases. The graph database is a NoSQL paradigm where navigation is based on links instead of joining tables.

Partial-sum queries in OLAP data cubes using covering codes [PDF]

open access: yes, 1997
A partial-sum query obtains the summation over a set of specified cells of a data cube. We establish a connection between the covering problem in the theory of error-correcting codes and the partial-sum problem and use this connection to devise ...

Text-Image Matching for Cross-Modal Remote Sensing Image Retrieval via Graph Neural Network

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2023
The rapid development of remote sensing (RS) technology has produced massive images, which makes it difficult to obtain interpretation results by manual screening. Therefore, researchers began to develop automatic retrieval method of RS images. In recent

Ranking Large Temporal Data [PDF]

open access: yes, 2012
Ranking temporal data has not been studied until recently, even though ranking is an important operator (being promoted as a firstclass citizen) in database systems.
