Your proven path to success in Machine Learning Interviews – developed by FAANG engineers. Unlock ML loops at top companies with a System Design approach.

System design is an important component of any ML interview. Being able to efficiently solve open-ended machine learning problems is a key skill that can set you apart from other engineers and increase the level of seniority at which you’re hired.

This course helps you build that skill, and goes over some of the most popularly asked interview problems at big tech companies. You’ll walk step-by-step through solving these problems, focusing in particular on how to design machine learning systems rather than just answering trivia-style questions. 

Once you’re done with the course, you’ll be able to not just ace the machine learning interview at any tech company, but impress them with your ability to think about systems at a high level. If you have a machine learning or system design interview coming up, you’ll find the course tremendously valuable.

# Introduction
Named entity linking (NEL) is the process of detecting and linking entity mentions in a given text to corresponding entities in a target knowledge base.

There are two parts to entity linking:

1. *Named-entity recognition*
 
   Named-entity recognition (NER) detects and classifies potential [named entities](https://en.wikipedia.org/wiki/Named_entity) in the text into predefined categories such as a person, organization, location, medical code, time expression, etc. (multi-class prediction).

2. *Disambiguation*

   Next, disambiguation disambiguates each detected entity by linking it to its corresponding entity in the knowledge base.

> 📝 The target knowledge base depends on the application, but for generic systems, a common choice is Wikidata or DBpedia.

Let's see entity linking in action in the following example. 


Let's get acquainted with the task of building an entity linking system.
