Semantic technology trends are expanding well beyond an interesting, more advanced search engine. Besides providing scientists with a more functional search engine, semantic technology is now being used to improve artificial intelligence and machine learning. Semantic technology uses a variety of tools and methods designed to add “meaning” to a computer’s understanding of data. When […]
What Is a Property Graph?
A property graph is a type of graph model where relationships not only are connections but also carry a name (type) and some properties. A property graph excels at showing connections among data scattered across diverse Data Architectures and data schemas. They provide a richer view on how data can be modeled over many different […]
A Brief History of Metadata
Metadata is a small amount of data designed to provide reference information about other data. For example, in 280 BC, the Great Library of Alexandria attached a small, dangling tag to the end of each individual scroll. The tags gave the title, subject, and author, allowing library users to assume the content, without having to […]
2021: Three Game-Changing Data Modeling Perspectives
Click to learn more about author Thomas Frisendal. Common wisdom has it that we humans can only focus on three things at a time. So, I had to cut down my January 2021 list of things of importance in Data Modeling in this new, fine year (I hope)! Looking at them from above, as we […]
Will They Blend? Meeting the Semantic Web
Click to learn more about author Martyna Pawletta. Let’s see if we can serve pizza via the Semantic Web and an analytics platform. Will they blend? Ontologies study concepts that directly relate to “being,” i.e., concepts that relate to existence and reality as well as the basic categories of being and their relations. In information science, […]
Ontotext’s GraphDB 9.2 Supports RDF
According to a recent press release, “Ontotext has released the 9.2 version of GraphDB – the most powerful RDF database for creating and maintaining knowledge graphs. In addition to the anticipated support for RDF*/SPARQL*, it brings improvements in the plug-ins for semantic similarity and versioning. The new Proof plug-in provides inference explanation… Knowledge graphs are […]
Seeing the Database Through a Different Lens
Click to learn more about author Greg Nist. I was frustrated. I’d spent two-and-a-half years as a consultant developing software for a state government agency, and I felt like we were running on a treadmill. Our ability to drive the agency forward to more effectively run its operations was being constrained. Constrained not by the […]
Knowledge Graphs and Data Modeling
Click to learn more about author Thomas Frisendal. Trip Report From Graphorum / Data Architecture Summit 2019 On October 14th thru 17th Chicago hosted the two co-located conferences Graphorum and Data Architecture Summit 2019 by DATAVERSITY®. It was two days of good tutorials and two good days of conference presentations. One thing to think about […]
Artificial Intelligence and Enterprise Knowledge Graphs: Better Together
At the heart of things, an enterprise knowledge graph supports decision and process augmentation based on linked data. These models of knowledge domains are created by subject matter experts with the help of machine learning algorithms. They live as virtual data layers on top of existing databases or data sets to link both structured and […]
The Atoms and Molecules of Data Models
Click to learn more about author Thomas Frisendal. I realized that I needed to know what the constituent parts of data models really are. Across the board, all platforms, all models etc. Is there anything similar to atoms and the (chemical) bonds that enables the formation of molecules? My concerns were twofold: As part of […]
