- 8. Knowledge Graphs representation alternatives 8 * Adapted from documentation at W3C https://www.w3.org/ Two ways of representing/storing a Knowledge Graph RDF-star (Resource Description Framework) Semantic Web: Good for common standards and data exchange Data model based on 3 parts: subject, predicate and objects Nodes’ properties added as predicates. Edges with properties are “triple-resources” (like “meta-nodes”) Storage: “Triple/Quad Stores” Graph Databases Any type of real-world information, can be represented in a Knowledge Graph 18 nodes (5 instances, 4 classes, 8 literals, 1 triple-resource) 19 relationships (triples) Knowledge Graph is a way of organizing data & information in the form of a graph A collection of interlinked concepts, entities, events that represent a network of real-world entities, the relationships between them. LPG (Labelled-Property Graph) Good for highly dynamic, transactional use cases Data organized as nodes, labels, relationships and properties Both nodes and edges can have properties Storage: Native Graph Databases 5 nodes (5 ids, 4 Labels, 8 properties) 4 relationships (2 properties)

- 10. Challenges 10 Decouple & Specialise Integrate & Standardise Abstract & Automate Use the right tools for the job Data Lake? Data Warehouse? Graph Database? LPG? RDF? No-SQL? Modular Design with Security in Mind Build a component-based architecture with coherent and practical principles. Think of data as a product Push and Pull Vs Serve and Consumer Make it easy to work with data across platforms. Searching and moving data is costly. Move to an ELT model, leverage first-party connectors, and document to promote the most optimal options. Standardise Apply FAIR principles Document and Promote Patterns Data Movement, Loading, Transformation. Template and Accelerate Teams should be able to spend more time analysing data and deriving insights than managing infra. Automate Leverage IaC, and automation pipelines to achieve consistent deployments.

- Integration of Diverse Data Sources: Vast amounts of data from various sources (clinical trials, scientific literature, genomic data, patient records, and regulatory documents). Knowledge graphs provide a unified framework for integrating and connecting heterogeneous data, enabling researchers and decision-makers to gain comprehensive insights across disparate data silos. Complexity of Biomedical Knowledge: The field of life sciences is constantly evolving, with new discoveries, insights, and publications emerging rapidly. Knowledge graphs capture biomedical knowledge's complex relationships and semantics, such as drug-target interactions, disease pathways, genetic associations, and adverse drug reactions. By organising and representing this knowledge in a structured format, knowledge graphs facilitate advanced analytics, hypothesis generation, and decision support for drug discovery, development, and clinical research. Semantic Search and Discovery: Traditional keyword-based search approaches often need help to capture the rich semantics and context of biomedical information. Knowledge graphs enable semantic search and discovery by encoding relationships between entities, concepts, and attributes in a graph-based data model. This allows researchers to navigate and explore biomedical knowledge more intuitively and context-awarely, facilitating the identification of relevant insights, hypotheses, and research opportunities. Data-driven Insights and Decision-Making: In today's data-driven healthcare landscape, pharmaceutical companies need robust analytics and decision-support tools to extract actionable insights from diverse datasets. Knowledge graphs are a robust foundation for advanced analytics, machine learning, and predictive modelling, enabling researchers to uncover hidden patterns and leverage the power of
- The Data Analytics Funnel
- Growing importance of knowledge graphs in data management and analysis. There is need for an efficient and reliable service to support both hosting and development of knowledge graphs. AZ is investing in this area to create a robust and scalable service.
- We are particularly excited about the future evolutions of our Insights Chat. Our next evolutionary steps in this journey we hope would unlock – Context switching between domains when interacting with a ChatBot powered by LLMs and underpinned by the different Knowledge Graphs curated and managed by functional teams The ability to connect across Knowledge Graphs at query time unlocks huge potential with regards to JIT – Just in Time Insights. Ability to observe, monitor and apply AI and Data governance consistently across projects on LLM-powered RAG applications Receive real-time user feedback. We’ve all heard about Data Mesh, but maybe Knowledge Mesh is due to arrive on the Hype Cycle Soon?
- When we talk about multiple siloed databases, we could imagine an archipelago. At the first glance, visiting all islands, doesn't seem an easy task!
- With the right infrastructure, multiple islands can be connected, and visiting them, suddenly, becomes way easier. Federating queries, across siloed databases, is like building bridges between islands. This allows running queries against multiple siloed data sources, without needing to migrate all data to a unified system.
