Towards Data Driven Publishing Leveraging Knowledge Graphs and Text Analytics Contech: 2018

This article explores the use of knowledge graphs and text analytics in data-driven publishing, focusing on the Ontotext Platform. Learn how knowledge graphs enhance traditional relational databases and how text analytics can provide semantic disambiguation and annotation. Discover how the combination of graph-based reasoning and vector space similarity can improve content search, recommendation, and relevance ranking. Gain insights into dynamic semantic publishing and its benefits for content curation, search, recommendation, and workflow optimization.

  5. Knowledge and Graphs

  6. Traditional relational databases only store information...

  7. Graphs treat the connections between information with equal importance.

  8. Knowledge graphs represent information in a manner similar to how a human understands information.

  9. Ontotext GraphDb; uses graph statements to reason and infer additional knowledge. Vector space indices for similarity.

  10. Graph; Reasoning & Inference S = Berners-Lee P = type O = Person S = Berners-Lee P = type O = Mammal DATA (RDF) S = Person P = subClassOf O = Mammal NEW Implied DATA (RDF) KNOWLEDGE (ONTOLOGY)

  11. Graph & Vector Space; Entity Awareness, Similarity +

  12. Big Knowledge Graphs; Provide Awareness • Important airports near london? • Most popular banks in UK • People mentioned together with Apple in the news

  13. Vector Space; Similarity &Concordance • Find similar content • Find similar concepts and link • Find relevant concepts for content

  29. To; Data driven publishing

  30. Dynamic Semantic Publishing Authoring • Rapid high value, lower cost content curation • Capture knowledge and meaning as re-usable data Search & Discovery • Unambiguous semantic search • Recommendation and Similarity Product • Re-purpose and aggregate with Business context • Generate new revenue streams

  31. Enhanced Publishing Workflow Authoring Editorial Production Delivery Discover Related Content Annotate With Concepts & Relations Dynamic Data driven products Contextual Semantic Search Recommend Related Content Organise & Improve Workflow Content Transformation Add references Link to products & archive Domain Modelled IA Personalised Content Streams Add Context

  32. DSP - BBC Sport • Goals • Create a dynamic semantic publishing platform that assembles web pages on-the-fly using a variety of data sources • Deliver highly relevant data to web site visitors with sub-second response "The goal is to be able to more easily and accurately aggregate content, find it and share it across many sources. From these simple relationships and building blocks you can dynamically build up incredibly rich sites and navigation on any platform." John O’Donovan, Chief Technical Architect, BBC

  33. The IET • Goals • Manageable, discoverable, searchable; Journals, research papers and articles • Semantic search using existing taxonomies • Intelligent citations and data provenance • Automated, dynamic repurposing of content assets • Enable new revenue opportunities
