Performance of Graph and Relational Databases in Complex Queries
Applied 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.

Bridging the Gap: Query by Semantic Example [PDF]
IEEE 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.

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