# Introduction

The Bigdata Knowledge Graph includes over 12 million entities such as companies, organizations, products, and locations. Each entity has a unique, point-in-time-aware identifier that can be used across services to search for content specifically referencing that entity. This ensures higher precision and reduces noise in search results.

The Knowledge Graph also features more than 7,000 categories spanning business, macroeconomic, and geopolitical topics.

Additionally, it contains thousands of sources available on Bigdata, allowing you to filter search results by source name, source rank, and country of origin.

The `knowledge_graph` service allows users to retrieve objects such as entities, topics, and sources. You can provide a text string to the [autosuggest](./autosuggest) method, which returns up to 20 highly relevant matches. If you already know the object type, you can use the more specific methods described below.
