RELATIONAL DATABASE AND GRAPH DATABASE: A COMPARATIVE ANALYSIS [PDF]

Journal of Process Management and New Technologies, 2017
Since 1970, relational database models have been in use for storing, manipulating and retrieving data. The importance of relational databases is going to decrease due to the exponential growth of data as it is difficult to work with large number of ...

Proteome Analysis of Corynebacterium diphtheriae–Macrophage Interaction

PROTEOMICS, Volume 26, Issue 8, Page 9-28, August 2026.
ABSTRACT Contact of Corynebacterium diphtheriae with macrophages induces adaptations on both bacterial and cellular sides. The study presented here was aiming to shed light on the simultaneous intracellular adaptation of the bacteria and changes in the proteome of the phagocytes in response to the internalization of C. diphtheriae.

Knowledge graphing in forensics: Modeling forensic case trajectories using news media

Journal of Forensic Sciences, Volume 71, Issue 4, Page 1693-1705, July 2026.
Abstract We employ a knowledge graph (KG) approach to aggregate qualitative information to harness and systematically incorporate contextual information into a forensic investigation. We are interested in tracing the spatial distribution and what happens to unidentified human remains after discovery—relationships and successive movements that are not ...

SPARQLing Neo4J

, 2020
The growth experienced by the internet in the past few years as lead to an increased amount of available data and knowledge obtained from said data. However most of this knowledge is lost due to the lack of associated semantics making the task of interpreting data very hard to computers.

Applying knowledge graphs: Migrant decedent case trajectories in South Texas

Journal of Forensic Sciences, Volume 71, Issue 4, Page 1706-1717, July 2026.
Abstract The phenomenon of migrant death at the Texas‐Mexico border is well documented, but questions remain as concerns its spatial distribution and what happens to human remains after discovery. To start exploring these questions, we developed a knowledge graph (KG) approach to aggregate qualitative information concerning migrant death and elucidate ...

The metadata ecosystem and AI: Enabling FAIR and AI‐ready data

AI Magazine, Volume 47, Issue 2, Summer 2026.
Abstract Reproducibility is a foundational tenet of science. As artificial intelligence (AI) becomes increasingly embedded across science, the need to accurately document the provenance, structure, and behavior of training data, models, and workflows grows correspondingly. Metadata, understood as explicit and structured knowledge about data and related

A multi‐source fusion and dynamic verification framework for scientific knowledge graph construction: Methods, evaluation, and applications

AI Magazine, Volume 47, Issue 2, Summer 2026.
Abstract The exponential growth of scientific literature—over 2.5 million papers and 3.5 million patents annually—poses critical challenges for knowledge discovery. To address these, we propose SCIMKG (Scientific Knowledge Graph), a framework for constructing scientific knowledge graphs via multi‐source heterogeneous multi‐source.
