The Future of Entity Resolution and Its Potential Applications

Can you imagine a world where all your data is perfectly organized and easily accessible from a single point of access? What if you could quickly and reliably connect data across multiple sources and even across languages? Such a world may seem out of reach, but entity resolution is making strides towards that end goal.

In this article, we'll explore the future of entity resolution and its potential applications, including how it can revolutionize data management and even alter our understanding of history.

What is Entity Resolution?

Before we dive into the future possibilities of entity resolution, let's first define what it is.

Entity resolution, also known as record linkage, data mastering, or de-duplication, is the process of identifying and reconciling records that refer to the same real-world entity. This is done by merging or linking records, creating a single, unified view of the entity in question.

For example, let's say you have a customer database containing a record for John Smith, who has a purchase history with your company. However, you also have another record for Jon Smit, with a slightly different spelling of the name, who has a different purchase history. Entity resolution would recognize that John Smith and Jon Smit are actually the same person and merge their records, creating a single, accurate view of the customer.

The Expanding Role of Entity Resolution

With the proliferation of digital data sources and the increasing demand for reliable, unified data, entity resolution has become an essential tool in the data management arsenal. It's used across a variety of industries, from finance to healthcare to retail.

In finance, entity resolution can help detect fraudulent activity by identifying suspicious connections between individuals and organizations. In healthcare, it can aid in patient matching, ensuring accurate diagnoses and treatments. In retail, it can help personalize customer experiences by accurately identifying individual preferences and purchase histories.

Given its versatility, it's no surprise that entity resolution is quickly becoming an indispensable tool for businesses and organizations.

The Future of Entity Resolution

So where is entity resolution headed? What developments can we expect to see in the next few years?

Natural Language Processing (NLP)

One exciting area of development is the incorporation of natural language processing (NLP) into entity resolution. NLP is a form of artificial intelligence that enables computers to analyze and understand human language. This could enable entity resolution to not only recognize links between records with different spellings, but also between records with different names and even in different languages.

This could revolutionize the way we handle multilingual data, streamlining the process of linking records across different languages and enabling us to gain new insights from previously disconnected datasets.


Another development that could have a significant impact on entity resolution is the incorporation of blockchain technology. Blockchain is a distributed ledger technology that allows for secure, decentralized data storage and sharing.

By incorporating blockchain into entity resolution, we could create a secure, tamper-proof system for reconciling records across different organizations and even across different countries. This could be particularly useful for industries such as finance and healthcare, where accurate record-keeping is essential.

Graph Databases

Finally, the rise of graph databases could also have a profound impact on the future of entity resolution. Graph databases are designed to represent data as nodes and edges, making it easy to understand connections between different records.

With the proliferation of data sources and the increasing complexity of relationships between entities, graph databases could enable faster and more accurate entity resolution. They could also enable us to gain new insights from previously disconnected datasets by highlighting connections that were previously hidden.

Potential Applications of Entity Resolution

As entity resolution continues to evolve, its potential applications become increasingly diverse and far-reaching. Let's explore some of the ways it could impact different industries and fields of study.

Business Intelligence

In the realm of business intelligence, entity resolution could enable companies to create a more accurate picture of their customers and target audiences. By linking customer records across different channels and platforms, businesses could gain a more complete understanding of individual preferences and behaviors, enabling them to make more informed decisions about marketing, product development, and more.

History and Genealogy

Entity resolution could also have interesting applications in the field of history and genealogy. By linking records of individuals and events across different sources and time periods, we could gain new insights into our collective past. For example, we could trace the movements of a particular historical figure, identifying previously unknown connections and relationships.

In genealogy, entity resolution could also aid in the process of family tree building, connecting individuals across generations and identifying previously unknown ancestors.


In healthcare, entity resolution could help improve patient outcomes by enabling accurate patient matching and improving the accuracy of medical records. By recognizing connections between different records, healthcare providers could gain a more complete picture of a patient's medical history and make more informed decisions about treatment.

Fraud Detection and Law Enforcement

Finally, entity resolution could also have important applications in the realm of fraud detection and law enforcement. By recognizing suspicious connections between individuals and organizations, it could aid in the detection and prevention of fraudulent activity. It could also aid in investigations, helping to identify previously unknown connections between suspects.


From improving business intelligence to revolutionizing our understanding of history, entity resolution has the potential to impact a wide range of industries and fields of study. As we continue to develop new technologies and techniques for entity resolution, we can expect to see new possibilities emerge.

Whether through the incorporation of natural language processing, blockchain, graph databases, or some as-yet-undeveloped technology, the future of entity resolution is sure to be exciting and full of opportunities for innovation. So keep an eye on this space - the possibilities are endless!
