Neo4j Graph Data Science: Powerful Innovation and Interconnected Insights

By: Sean Robinson (Director of Data Science), Golven Leroy (Data Scientist, Guest Contributor)

In this article, we’ll take a look at the Neo4j Graph Data Science Library by examining its capabilities, how it can be used with a Neo4j database, and how you can get started with the Neo4j Graph Data Science Library yourself.

What is Neo4j Graph Data Science?

Data Science in general differs from traditional analytics methods in that it incorporates advanced tools and techniques like machine learning (ML) / artificial intelligence (AI), and natural language processing (NLP) to make the most insightful, data-driven decisions and predictions possible. While traditional methods using graphs rely heavily on advanced statistics and graph-theory-related mathematics algorithms in order to summarize and analyze data, Neo4j Graph Data Science Library goes far beyond these disciplines to bring in extra-disciplinary knowledge and capabilities to its graph data science offering. Some examples include:

• Graph ML capabilities to drive more accurate predictions, to a level that is not often feasible using purely statistical approaches.
• Out-of-the-box ML pipelines for common use cases such as anomaly and fraud detection, recommendation engines, route optimization, and more.
• Project-to-production capabilities. Moving AI /ML projects from the development stage to production is difficult and requires significant and ongoing “tinkering” from qualified data scientists to accomplish that. The Neo4j graph data science library is built for deploying production-ready projects by leveraging experience, best business practices, and data science knowledge to provide many workflows to help expedite your business value.

The 4 Reasons Businesses Need Neo4j Graph Data Science / Graph Database for Critical New Insights

Graph data science (GDS) is increasingly demonstrating its place as part of the next generation of tools for advanced analytics for businesses and organizations as they continue seeking to gain a competitive advantage in a diverse marketplace.

Reason 1: Massive Data Scale Requires It

Many organizations have large and ever-increasing volumes of complex data for which traditional relational databases are not well-suited to handle. In contrast, graph data science on graph databases like Neo4j provide a much more suitable means to store and analyze this volume of data in an interconnected way that highlights the connectedness of the data, which is becoming particularly important for the increasingly advanced questions business leaders are asking of their data

Reason 2: Data Complexity Requires It

Complex data relationships in traditional databases require complex queries that can be slow and inefficient as they attempt to traverse disconnected datasets through joins and foreign keys. In contrast, graph databases are designed to optimize these connections thought relationships, making data analysis, including graph data science, faster and more efficient. This is especially useful for businesses and organizations that need to analyze large amounts of data in real-time to make informed decisions.

Reason 3: Relationship Accuracy Requires It

Data science conducted on a graph database (see more at What is a graph database) provides a more accurate real-world representation of complex data relationships where the critical insights are centered around how entities may be connected. Traditional relational databases are not well-equipped to handle this kind of interconnected data at scale. As a result of the frequently stilted modeling required, they can produce inaccurate results when attempting to analyze such data, with extensive queries requiring inordinate amounts of time to process. In contrast, graph databases are specifically designed to quickly manage complex, interconnected data relationships, with much less code required, making them more accurate and usable for data science and decision-making.

Reason 4: Advanced Insights Require It

Finally, because of the uniqueness of the surrounding technologies used to query and analyze the data, graph databases enable organizations to gain insights into their data that would be difficult if not impossible to obtain with traditional relational databases, whether using graph data science or not.

This can lead to optimized businesses and better decision-making driving competitive advantage in increasingly competitive landscapes. By using graph databases, organizations can surface incredibly valuable patterns and relationships within their data that were previously hidden in their vast amounts of data, enabling organizations to make more informed, better decisions.

• Native Graph Processing: Neo4j is a native graph database, which means it is optimized for processing and analyzing graph data. This allows for faster query performance and more efficient data processing. Read more on Neo4j performance and architecture.

Where Should You Start?

For installation of the Graph Data Science Library, we recommend following the Neo4j documentation here. Once GDS is set up, use these tips for best results:

• Tune the graph database configuration: Neo4j provides many configuration settings that can be tuned to optimize query performance and data processing. Adjusting these settings can help to speed up query response times and improve overall performance, which can make a big difference when running certain algorithms.

• Use appropriate graph algorithms: Neo4j provides a wide range of graph algorithms for various types of analysis, which is amazing, but it can be overwhelming at first. We recommend experimenting and researching which algorithm is most appropriate for your analysis goals. Different algorithms might have different rates of success! Once algorithm will most certainly not answer all of your data questions, and all of your analysis goals might not require full-blown GDS.

• Use Neo4j’s GraphAcadmy: Ultimately, if you want to have the best chances with Neo4j GDS, we recommend following the learning path for the Neo4j Graph Data Science Certification. It will take you through proper installation, cataloging, administration, cypher on GDS graph and overall Graph management.

Conclusion

Neo4j’s graph database has made it possible to extract crucial insights from complex data for several years. However, with the introduction of the Neo4j Graph Data Science Library, it has finally bridged the gap between data science and traditional methods of graph analytics.
