[Citation needed]: provenance with RDF-star

(Reading time: 7 - 13 minutes)
Provenance with RDF-star

In any Knowledge Graph-based project, keeping track of where data comes from is important. When you know the source of your facts or assertions, you can contextualize those facts: how relevant is assertion X to my current research, is it from a source that I personally trust, and if I have two conflicting views how can I decide which source to go with? Apart from issues of trust and confidence, tracking the source also can serve more mundane goals, such as knowledge graph maintenance: source X has published a new edition of their data set, so we need to replace the relevant data in our own Knowledge Graph, and so on.

Keeping track of the source of data is often referred to as provenance. In this blog post, we will look at provenance tracking in RDF Knowledge Graphs using the Wikidata dataset as an example, and we will look at how RDF-star and SPARQL-star, two new community efforts to extend the RDF model, can make this task easier.

Visual Ontology Modeling for Domain Experts and Business Users with metaphactory

In my previous blog post on building Knowledge Graph-driven, FAIR Data platforms I discussed the importance of data and data-driven decisions, processes and tools in accelerating digital transformation. Knowledge Graphs have revolutionized the way data can be accessed and used, and have helped enterprises overcome the challenges posed by distributed silos where information is available to limited audiences, in heterogeneous formats, and represented according to different models. They have led to great advances in terms of data integration, interoperability and accessibility, and have allowed companies to tap into the full potential of their data assets and transform data into valuable and actionable knowledge.

With metaphactory, our customers have been able to rapidly build Knowledge Graph-based applications enabling them to focus on business outcomes, reduce development efforts and quickly produce results that matter:

  • Customers in Life Sciences & Pharma have been able to fast-track drug development and drug repurposing.
  • Customers in Engineering & Manufacturing have established smart manufacturing processes and have sped up research, documentation processes and industrial configuration management.
  • Customers in Government and Cultural Heritage organizations have streamlined data curation and digital publishing processes, making cultural heritage content intuitively available to the public.

All of these applications utilize a semantic data model to not only describe the domain, but also drive data integration, tie in term vocabularies, or derive UI templates to create a model-driven user interface. Such a semantic data model is called an ontology. According to Gartner, "Ontologies are structural frameworks for organizing information and are used as knowledge representation. Ontology management supports and expands data modeling methodologies to exploit the business value locked up in information silos."

A Knowledge Graph for the Agri-Food Sector

(Reading time: 7 - 13 minutes)
Farm Management Stakeholders

Raul Palma leads the data analytics and semantics department at the Poznan Supercomputing and Networking Center (PSNC), where he coordinates the R&D activities and the center’s participation in various EU projects around these topics. In this guest post for the metaphacts blog, Raul explains how knowledge graph technology can address data integration challenges in the agri-food sector, showcasing it through a few use cases. He describes how he leveraged metaphactory to build a domain-specific application - FOODIE - that delivers intuitive access to distributed, heterogeneous data sources and allows end users to extract meaningful insights.

FOODIE is an agriculture knowledge hub delivered as a Web application built on top of metaphactory Knowledge Graph platform. The application enables an integrated view and access over multiple datasets which have been collected from various and heterogeneous sources relevant to the agriculture sector, transformed, and published as Linked Data / in a Knowledge Graph.

Smart Solutions for Identifying Compatible Components

This article was co-written by Felicity Mulford (Oxford Semantic Technologies). Thank you to Valerio Cocchi (Oxford Semantic Technologies), and Ilija Kocev and Daniel Herzig (metaphacts) for their work on the demo system.

Determining compatibility between individual entities is an essential process for many businesses, across various industries and business models; from industrial configuration, supply chain, bill of materials, evaluating terms in contracts, or even for match making apps. The process may sometimes require the user to check hundreds of thousands or millions of possible combinations, to assess whether components fit together, or if components meet specified requirements. Additional factors may also need to be taken into account, for example, regulations or customer budgets. Traditional approaches are inefficient for modern day applications due to the large volumes of data, heterogeneity of data formats, complexity of customer specifications, and concerns over scalability.
