Knowledge graphs are quickly emerging as a powerful tool for managing and analyzing complex datasets. By organizing data into a network of interconnected concepts and relationships, knowledge graphs use cases offer a more flexible and intuitive approach to data management than traditional relational databases.

Think of a knowledge graph as a map for data. It organizes all your information, connecting related pieces like how cities and towns are linked by roads on a map. This makes it easier for you to find what you’re looking for, and also discover interesting connections that you might not have thought about before.

Knowledge graphs are like a clever puzzle that pieces together all your data. They use links and tags to show how each piece fits together, simplifying the process of combining, understanding, analyzing, and sharing your data.

In this article, we will explore some of the most popular knowledge graph use cases in data analytics, including recommendation systems, fraud detection, natural language processing, entity resolution, and machine learning. We will also discuss the benefits and challenges of using knowledge graphs in data analytics, and provide some examples of real-world applications.

Knowledge Graphs: Bridging the Gap Between Data and Understanding

Knowledge Graphs are a revolutionary technology that turns raw data into machine-understandable knowledge. However, to fully understand the definition of knowledge graphs, it is essential to comprehend the differences between data and knowledge. Knowledge is:

1. Situational
2. Layered
3. and constantly changing due to new discoveries.

These contextual factors are often missing from traditional data management systems, leading to gridlock, timeline delays, missing datasets, and mistrust.

Knowledge Graph use cases are specifically designed to address the fluctuating nature of knowledge. They provide a flexible foundation for digital operations, seamlessly integrating new data, definitions, and requirements. Unlike traditional data management systems, Knowledge Graphs capture context, allowing for nuanced understanding and associations between concepts. This makes it easier to master data, add new data sources or properties, and perform analyses with greater accuracy and trust.

The ability of Knowledge Graphs to represent complex relationships and dependencies between data entities enables a variety of use cases, including recommendation systems, fraud detection, natural language processing, entity resolution, and machine learning. Overall, Knowledge Graph use cases offer a powerful and flexible approach to data analytics, enabling users to integrate, analyze, and visualize complex data sets in new and innovative ways.

Technically speaking, a knowledge graph can be defined as a graph-based knowledge representation that organizes and integrates information from multiple sources, in a manner that enables machine understanding and reasoning.

At its core, a knowledge graph is a collection of
1. nodes (representing entities or concepts) and
2. edges (representing relationships between these entities or concepts).

The nodes and edges are annotated with labels and properties that provide additional context and semantics to the data. This graph-based structure allows for efficient and flexible representation of complex and dynamic knowledge and enables various forms of analysis and inference.

To create a knowledge graph, data from various sources are first extracted, transformed, and loaded into a graph database. This data can come from structured sources such as relational databases, or from unstructured sources such as text, images, or audio. Once loaded, the data is mapped to a shared schema or ontology, which defines the entities, properties, and relationships that are relevant to the domain of interest. In addition, knowledge graphs can be enriched and extended over time as new data sources become available, making them a powerful and adaptive tool for knowledge management and discovery.

Several tools can help you build a knowledge graph:

1. Neo4j and TigerGraph are graph databases used for storing and managing large amounts of graph data. They’re popular choices for creating knowledge graphs.
2. RDF4J is a Java framework used for creating and managing RDF graphs, a standard format for knowledge graphs.
3. Linked Data Platform (LDP) is a standard for publishing and consuming linked data. It helps build knowledge graphs that can be linked and shared across different applications.
4. Ontology Engineering Tool Suite (OETS) helps create and manage ontologies, a form of knowledge graph that represents a domain of knowledge formally.

History of Knowledge Graph: Start with Google

The term “knowledge graph” was popularized by Google when it launched the Google Knowledge Graph in 2012. The Google Knowledge Graph is a knowledge base that uses a graph-structured data model to enhance the quality of search results by providing direct answers, contextual suggestions, and a summary of key information related to the search query. It sources information from a variety of databases and uses machine-learning techniques to understand the connections and relationships between entities. You can check Google KG API and experiment as well.
