Specific characteristics

GRAKN.AI makes working with complex data easy by providing:

  1. An ontology as a flexible schema that allows you to model the world and all the complexities of type hierarchies and hyper-relationships contained within it.
  2. A query language that uses machine reasoning for retrieving explicitly stored data and implicitly derived knowledge.

Competitive advantages
  1. Expressive data model: Grakn allows you to model the real world.
  2. Logical integrity of information: Grakn maintains higher data quality with stronger information consistency than any other database.
  3. Flexible data model: Grakn allows your business model to evolve regularly.
  4. Machine reasoning query language: Graql allows you to discover deeply hidden and implicit associations within the data.
  5. Optimised query execution: Graql reduces the time and complexity in writing deep relational queries while automatically optimising the execution of query traversal.
  6. Graph analytics out-of-the-box: Grakn allows you to spend more time analysing your data and less time coding algorithms for analysis.

Typical application scenarios
  • Semantic Search: GRAKN.AI allows you to accurately understanding of a query's intent and the meaning of its terms.
  • Automated Fraud Detection: GRAKN.AI allows you to identify hidden links across multiple transactions.
  • Intelligent Chatbots: GRAKN.AI allows you to disambiguate queries, retrieve context-specific knowledge, and generate the most useful answers.
  • Advanced Drug Discovery: GRAKN.AI provides an integrated database for research.
  • Dynamic Risk Analysis: GRAKN.AI allows for for dynamic risk management in strategic decisions.
  • Other key areas: User-Centric Systems, Data Exploration Tools, Content-based Recommendation Engines and Knowledge Management Systems.
