Information Retrieval System explained in simple terms!
Introduction
While searching for things over internet, I always wondered, what kind of algorithms might be running behind these search engines which provide us with the most relevant information? How do they decide which result to show for which set of search keywords.
This might be a no brainer for a few people, but definitely an interesting problem for some of the best brains around the world. To find the answer, I read every guide, tutorial, learning material that came my way. Eventually, I learnt about the Information Retrieval System.
What is Information Retrieval System?
Information retrieval system is a network of algorithms, which facilitate the search of relevant data / documents as per the user requirement. It not only provides the relevant information to the user but also tracks the utility of the displayed data as per user behaviour, i.e. Is the user finding the results useful or not?
In this article, I have explained the basic techniques used for Information Retrieval. The algorithms used by Yahoo and Google are much
