AI, natural language processing, and semantic search applications are powering new data management practices. Data teams can use Knowledge Graph in conjunction with these tools to derive insights that traditional databases can’t provide.
Knowledge graphs help organize contexts, connections, and ontologies into data management systems. It also models relationships between real-world entities to improve accuracy and insight for various data processing tasks.
Knowledge graphs often work on top of graph databases and describe the ontology of information in the graph database. This combination provides a richer way to characterize what the underlying data means for AI applications, rather than using traditional databases such as relational databases. A knowledge graph-powered database is easier for business users to work with and understand than a traditional database.
Comparing Knowledge Graph and Database
Gregor Stühler, CEO of procurement automation platform Scoutbee, said the main difference between the Knowledge Graph and traditional databases is how each stores data.
Traditional databases store data in tables using predefined schemas. Organize data into rows and columns and use primary and foreign keys to establish relationships between entities.
Traditional databases are efficient at storing structured data and processing basic queries, but it can be difficult to capture complex relationships and infer new knowledge from the data.

“Traditional databases are efficient at storing structured data and processing basic queries, but they can be difficult to understand complex relationships and infer new knowledge from data,” says Stühler. says Mr.
A knowledge graph is a network of interconnected entities and their relationships, represented as nodes and edges. Information is organized to model real-world objects and their relationships, and that information is communicated to the machines that consume it.
Knowledge graphs and graph databases
A knowledge graph works in conjunction with a graph database. Graph databases themselves map the relationships between data sets much like sketching a system on a whiteboard. The Knowledge Graph sits on top of this database, representing complex real-world entities and showing the relationships between them. Combining graph databases and knowledge graphs enables non-technical users to visualize and analyze the data they need.
Think of the knowledge graph as a kind of knowledge base, says Gabrielle Montagne, senior product manager for the machine learning platform at enterprise search platform Coveo. A knowledge graph uses a graph-structured data model to integrate data and store interlinked descriptions of entities, events, situations, or abstract concepts. It also encodes the underlying semantics of the term. A knowledge graph contains an ontology that allows humans and machines to understand and reason about its contents.
Graph databases use graph structures for semantic queries about nodes, edges, and properties used to represent and store data. However, graph databases typically do not contain ontologies. As a result, more work is required to store and reason about complex knowledge representations in the knowledge graph. Knowledge graphs can be grouped together to form a knowledge graph database.
Deriving knowledge in real-world scenarios
Cropin, a farm management platform provider, works with a knowledge graph database to improve AI workflows. Most information is statistical or textual, but the company is increasingly looking for ways to extract knowledge from images and scenes, said Praveen Pankajakshan, vice president of data science and AI. Cropin needs to manage these data sources in order to train better AI algorithms.
Pankajakshan’s team is working on a crop knowledge graph that can automatically transform raw images into organized knowledge about over 500 crops and 10,000 crop varieties. This process transforms the information embedded in the data into a linked form and stores it in a machine-usable form in the knowledge graph. Tools and platforms can ingest data and provide insights using information about geography, climatic conditions, soil types, cultivation lifecycles and other factors.
For example, corn and soybeans have different meanings for subtle color changes. Cropin can use the knowledge graph to feed the meaning of these changes into various AI algorithms. As a result, the company can advise farmers on the best watering, fertilizing and pest control interventions.
The company can also combine knowledge graph information with real-time data to help farmers understand issues and make better decisions about growing practices and land management.
Benefits of the Knowledge Graph
Graph technology is invaluable for storing and visualizing data with complex relational structures, said Stühler. Knowledge Graph makes it easier to incorporate new data points than traditional databases. For example, his team is working on an application that maps risks across supply chains across multiple countries. Data His tables are not practical for such use cases, but graphs enable advanced analytics and machine learning.
Graph technology helps you organize your data and connections and make them readily available. When the user needs to populate the data, no additional work is required to calculate or map anything. To examine supply chain risks, dangerous Adds a node related to a specific city node in the Knowledge Graph. In contrast, tables are generally better for static data that is not complex or has no relationship to other data points.
The Knowledge Graph can also connect data points about internal customers, suppliers, and third parties. Data scientists can run algorithms to analyze relationships and draw conclusions.
A large-scale language model (LLM) that understands and summarizes content as well as creates and predicts new content adds immeasurable value, Stüller said. The LLM frontend improves interactions and the Knowledge Graph enables semantic search of data based on interactions with other his LLMs.
Examples of using the Knowledge Graph
Ryan Oattes, co-founder and CTO of Kobai, a decision intelligence platform, says data teams can use several metrics to assess when their knowledge graphs are at their best. According to Coveo’s Montagne, knowledge graphs are ideal for storing and visualizing complex, interrelated data that is difficult to represent in traditional databases.
Examples of information suitable for knowledge graphs include:
Biomedical data models of the complex interactions between genes, proteins, and diseases enable researchers to identify potential drug targets and develop new therapeutics.
Financial data such as stock prices, market trends and investment portfolios to analyze market trends and make investment decisions based on a wide range of data sources.
Social network data such as user profiles, connections and interests to personalize content and recommendations based on your interests and connections.
Product data such as features, specifications and reviews to manage product development and ensure consistency across multiple channels and platforms.
A high degree of interconnectivity between information such as maintenance work instructions, production line and aircraft machinery, and the complex relationships between spare parts needed to facilitate the work.
A hierarchical structure of information for tracking the performance of parts, systems, and manufacturing processes.
How to implement the technology
A new workflow is required to get the best results with the Knowledge Graph. Our domain experts will help you get started.
“The best knowledge graphs contain terminology and structures that reflect people’s understanding of a particular domain, rather than being derived from the data store where the data originated,” Ortes said. rice field. This allows for maximum collaboration and reuse, and the maximum he has is two opportunities. Values from the Knowledge Graph.
A schema should describe the ecosystem to properly reflect reality.
“Knowledge graphs live and die on the strength of their ontologies,” says Stühler.
Also consider how LLM can help you build your ontology. LLM helps organizations understand how schemas and topics are structured and describe their ecosystem in a meaningful way.
LLM also helps detect duplicate nodes that may occur in graph databases. These models can manage, structure, and improve your knowledge graph.
“Eventually, LLMs will replace how data is stored and how data is manipulated. But the knowledge graph will live on in terms of aggregation, reflection, and description,” Stühler said. I’m here.
