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

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

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

A Query Language for Data Access in Ubiquitous Environments
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]
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]
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
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]
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]
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
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 ...
