marmap: A package for importing, plotting and analyzing bathymetric and topographic data in R. [PDF]

open access: yesPLoS ONE, 2013
In this communication we introduce marmap, a package designed for downloading, plotting and manipulating bathymetric and topographic data in R. marmap can query the ETOPO1 bathymetry and topography database hosted by the NOAA, use simple latitude ...

Query-by-Example On-Device Keyword Spotting [PDF]

open access: yes2019 IEEE Automatic Speech Recognition and Understanding Workshop (ASRU), 2019
A keyword spotting (KWS) system determines the existence of, usually predefined, keyword in a continuous speech stream. This paper presents a query-by-example on-device KWS system which is user-specific. The proposed system consists of two main steps: query enrollment and testing.

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

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 ...

Bridging the Gap: Query by Semantic Example [PDF]

open access: yesIEEE Transactions on Multimedia, 2007
A combination of query-by-visual-example (QBVE) and semantic retrieval (SR), denoted as query-by-semantic-example (QBSE), is proposed. Images are labeled with respect to a vocabulary of visual concepts, as is usual in SR. Each image is then represented by a vector, referred to as a semantic multinomial, of posterior concept probabilities.

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)

Querying Knowledge Graphs by Example Entity Tuples [PDF]

open access: yesIEEE Transactions on Knowledge and Data Engineering, 2015
We witness an unprecedented proliferation of knowledge graphs that record millions of entities and their relationships. While knowledge graphs are structure-flexible and content rich, they are difficult to use. The challenge lies in the gap between their overwhelming complexity and the limited database knowledge of non-professional users.

Efficient & Effective Selective Query Rewriting with Efficiency Predictions [PDF]

open access: yes, 2017
To enhance effectiveness, a user's query can be rewritten internally by the search engine in many ways, for example by applying proximity, or by expanding the query with related terms.

Audio Query by Example Using Similarity Measures between Probability Density Functions of Features

open access: yesEURASIP Journal on Audio, Speech, and Music Processing, 2010
This paper proposes a query by example system for generic audio. We estimate the similarity of the example signal and the samples in the queried database by calculating the distance between the probability density functions (pdfs) of their frame-wise ...

Pay One, Get Hundreds for Free: Reducing Cloud Costs through Shared Query Execution

open access: yes, 2018
Cloud-based data analysis is nowadays common practice because of the lower system management overhead as well as the pay-as-you-go pricing model. The pricing model, however, is not always suitable for query processing as heavy use results in high costs ...
