Extra insights
The growth potential of today’s businesses increasingly lies in the value of their data assets. How that data is stored, governed, and made accessible is critical to turning information into real business advantage. Organizations that invest in improving their data and knowledge management practices can unlock hidden value, respond more effectively to market trends, and gain a significant competitive advantage. Graphwise’s five-star model navigates you through the journey to data and knowledge management that keeps you competitive and ensures growth.
The company's key offerings are:
- Knowledge Management Suite
The Graphwise Knowledge Management Suite surfaces the entire enterprise knowledge of structured knowledge (spreadsheets, statistics, performance reports) and unstructured knowledge (emails, minutes, policy documents, …). You get more reusable and customizable content, providing the full picture and reducing costs by eliminating the need to rewrite, reformat and republish. The Graphwise approach uses automated tagging, natural language processing, semantic search and recommendation together with knowledge graphs to build a rich knowledge infrastructure to deliver knowledge as a service.
- Data Management Suite
The Data Management Suite facilitates the management and transformation of enterprise data siloes into actionable data that can be used for intelligent systems. The Data Management Suite comprises GraphDB’s RDF database and OpenRefine and UnifiedViews to help consolidate data from various formats and identify hidden connections between data objects. These capabilities serve as the foundation for enterprises to scale their systems effortlessly, while ensuring data remains well-structured and classified.
- AI Platform
The Graphwise AI platform combines knowledge graph technology with generative AI to unify and query structured and unstructured data through a semantic layer. It uses graph modeling, semantic enrichment, and large language models to automate knowledge management, improve AI accuracy, and enable natural language interactions for search, recommendations, and analytics. By integrating Retrieval Augmented Generation (RAG), ontology management, and multi-modal data, Graphwise helps organizations gain insights, enhance decision-making, and scale AI-driven processes across various domains
