In the information world, we are continuously dealing with text content that can mean a variety of things. Rich sources of information such as the news, email, text or social media messages, contain all kinds of entities and depending on the type of information entities can mean multiple things such as events, people, relationships between people, places or organizations. Unlike structured data such as databases or tables, natural texts are made up of free-flowing information without a set schema. Regular expressions (regex) can help extract some entities such as phone numbers based on a pattern, but extracting other information like names of people, relationship between different entities or details of calendar events requires more advanced language processing in order for an NLP application to build the intelligence and refer such entities to Knowledge Graphs for example.
