What is OpenSPG
OpenSPG is a knowledge graph engine based on the SPG framework, launched by Ant Group in collaboration with the OpenKG community. OpenSPG integrates the structural nature of LPG and the semantic nature of RDF, overcoming the problem of RDF/OWL semantics being complex and difficult to implement, while inheriting the advantages of LPG's simple structure and compatibility with big data systems. OpenSPG provides capabilities such as explicit semantic representation, logical rule definition, and operator frameworks, supports pluggable adaptation of basic engines and algorithm services from various vendors, and enables the construction of custom solutions. OpenSPG uses efficient knowledge transformation to help improve data value and application value, making it suitable for various business scenarios such as finance.
Main Features of OpenSPG
- Semantic Modeling (SPG-Schema): Responsible for the design of a Schema framework for semantic enhancement of property graphs, including subject models, evolution models, predicate models, etc.
- Knowledge Building (SPG-Builder): Supports the import of structured and unstructured knowledge, is compatible with big data architectures, provides a knowledge building operator framework, and realizes the transformation from data to knowledge.
- Logical Rule Reasoning (SPG-Reasoner): Abstracts KGDSL (Knowledge Graph Domain Specific Language), provides programmable symbolic representation for logical rules, and supports rule reasoning and neural/symbolic hybrid learning.
- Programmable Framework (KNext): Provides scalable, process-oriented, and user-friendly componentized capabilities, realizes the isolation of the engine from business logic and domain models, and enables rapid definition of graph solutions.
- Cloud Adaptation Layer (Cloudext): Supports business systems in connecting to the open engine based on SDKs, building business frontends, and adapting custom graph storage/graph computing engines and machine learning frameworks.
Technical Principles of OpenSPG
- Semantic Representation of Property Graphs: The OpenSPG framework creatively integrates the structural nature of LPG (Labeled Property Graph) and the semantic nature of RDF (Resource Description Framework), providing a graph representation method that is both simple and rich in semantics.
- Compatible Progression Across Knowledge Levels: OpenSPG supports the construction and continuous iterative evolution of graphs under incomplete data conditions, and supports the construction and management of knowledge graphs when data is incomplete or changing.
- Connection Between Big Data and AI Technology Systems: The OpenSPG framework effectively connects big data technology and AI technology, supports efficient knowledge transformation of massive data, and enhances the value of data and applications.
- Development of Domain Knowledge Models and Operators: New business scenarios can quickly build domain models and solutions based on extending domain knowledge models and developing new operators.
- Definition of Logical Rules and Semantic Rules: Define logical rules based on KGDSL, enabling machines to understand and process complex business logic, and supporting rule reasoning and neural/symbolic hybrid learning.
