ChatGPT dialogue on graph databases and knowledge graphs

I enjoy talking with colleagues about technology and also about my work. Today I was alone at home and had a chat about the graph database market with ChatGPT, Dec. 15 version. Below are my questions and ChatGPT's answers. Impressive!

I need to start a project that will manage highly interrelated data: what do you suggest to use, a property graph database or an RDF triple store and why?

Both property graph databases and RDF triple stores are suitable for managing highly interrelated data. The choice between the two depends on your specific requirements and needs. Here are some factors to consider when deciding which one to use:

1. Data model: Property graph databases use a graph data model, which consists of nodes (representing entities or objects) and edges (representing relationships between nodes). RDF triple stores use a triple data model, which consists of subject-predicate-object triples (also known as "statements"). Each triple represents a piece of information in the form of a subject, a predicate (a verb or property), and an object.
2. Data representation: Property graph databases are more flexible in terms of data representation, as they allow you to store any type of data in nodes and edges. RDF triple stores, on the other hand, are more strict in terms of data representation, as they only allow you to store URI-based resources as subjects and objects, and predicates must be URIs as well.
3. Query language: Property graph databases typically use a proprietary query language (e.g. Cypher for Neo4j). RDF triple stores, on the other hand, use a standardized query language called SPARQL, which is based on SQL and allows you to query, insert, and modify data in the store.
4. Scalability: Both property graph databases and RDF triple stores can scale to large datasets. However, RDF triple stores are generally more scalable, as they use a distributed architecture that allows them to scale horizontally across multiple machines. Property graph databases, on the other hand, typically scale vertically by adding more resources (e.g. memory, CPU) to a single machine.
5. Use cases: Property graph databases are well-suited for applications that require fast traversal of the graph, such as recommendation engines, fraud detection, and network analysis. RDF triple stores are well-suited for applications that require the ability to query and reason over data, such as knowledge graphs, semantic search, and data integration.

In summary, if you need to store and query data using a flexible data model and a proprietary query language, a property graph database may be the better choice. If you need to store and query data using a strict data model and a standardized query language, and scalability is a key requirement, an RDF triple store may be a better fit.

Interesting, so you think property graph databases don't scale much! I work for a graph database vendor called Ultipa (you probably don't know this company yet because your engine has been trained with older contents and only in recent months we released more information about our database). Our database has a great and real horizontal scalability. Are you really sure about what you just wrote?

I apologize if my previous response gave the impression that property graph databases do not scale well. This is not necessarily the case for all property graph databases. Some property graph databases are designed to scale horizontally across multiple machines, similar to RDF triple stores, and may be able to handle large datasets efficiently.

The scalability of a database depends on a variety of factors, including its architecture, design, and the specific workloads it is being used for. It is important to carefully evaluate the scalability requirements of your application and choose a database that is able to meet those requirements.

I am not familiar with Ultipa, so I cannot speak to the specific scalability characteristics of their database. However, it is always a good idea to carefully evaluate the scalability of any database you are considering using, regardless of the vendor. This may involve benchmarking the database with representative workloads, reviewing documentation and performance reports, and consulting with experts and other users of the database.

Some colleagues say that one day there will be no difference between RDF triple store and property graph, and the functionalities of one will be present in the other data model. What are your thoughts on this?

It is certainly possible that the distinction between property graph databases and RDF triple stores may become less clear in the future, as both types of databases continue to evolve and incorporate new features. However, it is unlikely that the fundamental differences between the two data models will disappear completely.

Property graph databases and RDF triple stores have different underlying data models and use different query languages, and these differences are likely to remain a key part of their respective identities. Property graph databases are designed to represent data as a graph of nodes and edges, and use a proprietary query language that is optimized for graph traversal and manipulation. RDF triple stores, on the other hand, are designed to represent data as a set of subject-predicate-object triples, and use a standardized query language (SPARQL) that is optimized for querying and reasoning over data.

That being said, it is possible that some property graph databases may incorporate features that are traditionally associated with RDF triple stores, such as the ability to query data using SPARQL or the ability to represent data using a triple data model. Similarly, some RDF triple stores may incorporate features that are traditionally associated with property graph databases, such as the ability to represent data using a graph data model or the ability to traverse the graph efficiently.

In summary, it is possible that the differences between property graph databases and RDF triple stores may become less pronounced over time, but it is unlikely that the two data models will become completely interchangeable.

Is it possible to add reasoning or inference to a property graph database? How?

Yes, it is possible to add reasoning or inference capabilities to a property graph database. Reasoning or inference refers to the ability to automatically deduce new knowledge or conclusions from existing data.

There are several ways in which reasoning or inference can be added to a property graph database:

1. Using built-in reasoning capabilities: Some property graph databases, such as Neo4j, have built-in reasoning capabilities that allow you to perform inference over the data stored in the database. For example, Neo4j's built-in reasoning capabilities include support for temporal reasoning, spatial reasoning, and graph pattern matching.
2. Using a reasoning engine: You can use a reasoning engine, such as Pellet or Jena, to perform reasoning over the data stored in a property graph database. Reasoning engines can be integrated with the database using APIs or through the use of custom plugins.
3. Using a rule-based system: You can use a rule-based system, such as CLIPS or Drools, to perform reasoning over the data stored in a property graph database. Rule-based systems allow you to define rules that specify how to derive new knowledge or conclusions based on existing data.
4. Using a machine learning model: You can use a machine learning model, such as a neural network or a decision tree, to perform reasoning over the data stored in a property graph database. Machine learning models can be trained on a dataset and used to make predictions or infer new knowledge based on the patterns they have learned.

In summary, there are several ways to add reasoning or inference capabilities to a property graph database, depending on your specific requirements and needs. It is important to choose the approach that is most suitable for your application and dataset.

Considering what you just said, it is very easy to add some of the RDF triple store key features to a property graph database!

It is possible to add some of the key features of RDF triple stores to a property graph database, depending on the specific features you are interested in and the capabilities of the property graph database you are using.

For example, you can use a reasoning engine or a rule-based system to perform reasoning over the data stored in a property graph database, similar to how these features are used in RDF triple stores. You can also use standardized query languages, such as SPARQL, to query the data stored in a property graph database, similar to how they are used in RDF triple stores.

However, it is important to note that property graph databases and RDF triple stores are based on different data models and have their own unique characteristics and capabilities. While it is possible to add some features of one data model to the other, it is not necessarily easy or straightforward to do so.

In summary, while it is possible to add some features of RDF triple stores to a property graph database, it is important to carefully evaluate the capabilities of the property graph database you are using and consider whether it is the best fit for your specific requirements and needs.

What a virtual knowledge graph is?

A virtual knowledge graph is a virtual representation of a knowledge graph, which is a structured dataset that represents real-world concepts and their relationships. A virtual knowledge graph is created by combining data from multiple sources and mapping it to a common data model, such as a graph data model or a triple data model.

Virtual knowledge graphs can be used for a variety of purposes, such as enabling more accurate and efficient search, improving the personalization of online services, and supporting data integration and interoperability across different systems.

Virtual knowledge graphs can be implemented using a variety of technologies, such as property graph databases, RDF triple stores, and machine learning models. The choice of technology depends on the specific requirements and needs of the application.

In summary, a virtual knowledge graph is a virtual representation of a knowledge graph that is created by combining and mapping data from multiple sources. It can be used for a variety of purposes and implemented using a variety of technologies.
