#Ontology-Mediated Query Answering (OMQA) is a framework to answer queries over RDFS or OWL Knowledge Bases (KB). OMQA has been extended to SPARQL queries. #Research shows semantics can be defined that satisfies all requirements for SPARQL queries

#Semantic #technology, decision intelligence, knowledge #datascience will be our companions in the next years, so it's recommended to start exploring #graphdatabases, #ontologies, knowledge representation systems #knowledgegraph #AI #2020NewYear #trends

multiple tables linked by connected fields. Setting up a relational database requires a person who understands data structures. And if new information is added, or new relationships become important, the database administrator will need to change the structure of the database and, most likely, update the user interface as well. So what do you do if you have a data set where you can't map out the relationships ahead of time? Where instead of being connected by a single data point, people can be connected by things you can't predict in advance? Maybe two people are on the same baseball team or like the same types of books or live in the same city. Adding each of those items as a separa
