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.

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

gmos: Rapid Detection of Genome Mosaicism over Short Evolutionary Distances. [PDF]

open access: yesPLoS ONE, 2016
Prokaryotic and viral genomes are often altered by recombination and horizontal gene transfer. The existing methods for detecting recombination are primarily aimed at viral genomes or sets of loci, since the expensive computation of underlying ...

A Query Language for Data Access in Ubiquitous Environments

open access: yesCLEI Electronic Journal, 2018
Recent progress in ubiquitous computing technology is allowing development of new and so- phisticated applications that are now able to store very large data on the mobile device itself, besides access data stored remotely. Thus emerges the need to query

Query-by-Example Speech Search Using Recurrent Neural Acoustic Word Embeddings With Temporal Context

open access: yesIEEE Access, 2019
Acoustic word embeddings (AWEs) have been popular in low-resource query-by-example speech search. They are using vector distances to find the spoken query in search content, which has much lower computation than the conventional dynamic time warping (DTW)

Horizontably Scalable LSM-tree Based Index for Full-Text Search Boolean Queries

open access: yesСовременные информационные технологии и IT-образование, 2022
Let there be a set of objects, where each object is characterized by Boolean features. Let logical query or Boolean query denote a query to find objects characterized by a Boolean function by features, for example, “documents with all words ...and any ...

A locally weighted learning method based on a data gravitation model for multi-target regression

open access: yesInternational Journal of Computational Intelligence Systems, 2018
Locally weighted regression allows to adjust the regression models to nearby data of a query example. In this paper, a locally weighted regression method for the multi-target regression problem is proposed.
