“DATA MINING and CRIMINOLOGY” Data Mining is a technique in which the data is analyzed to find patterns of useful information. Data Mining, basically, is an analytical tool to examine data to convert it into useful information. Data analysis helps predict behaviour from the patterns extracted from the mining. Finding patterns from data is useful for the marketing, fraud detection and many more other purposes. For example, a leading shopping brand in their analysis discovered that when women bought weight reducing product on weekends, they tend to buy some skin product too. Further analysis showed that these shoppers typically bought only low fat products available. The retailer concluded that they get tempted to buy the skin product too as they are too conscious of their looks. This piece of information was used so as to increase the revenue of the shopping place. For example, the weight reducing products display was moved closer to cosmetics display. Data mining technique uses various factors to analyze and examine the data. The factors are association, sequence, classification, clustering and forecasting. Data Mining, sometimes, is also referred as ‘Knowledge Discovery’. There are approaches where a hypothesis is formed and then, it

is experimented to find if it true or not. But in the data mining technique, information is discovered while identifying repetitive patterns in large set of data. The technological advancement has favoured this technique the most. With the tools that are made available by the present technology, the data storage cost has reduced drastically and moreover, the data is more readily available and accessible. The organisations, now-a-days, are using data mining technique to find patterns in every possible field like to find pattern in customer information of a grocery store, providing in assistance in research in medical field etc. and etc. Data mining is primarily used by the organisations who want to serve their customer at their best as well as want to gain benefit. By following trends and patterns in sales, the companies determine the price of the product, the display placement of product, market competition, customer demographics and much more. The price of the product is determined on the sale of the product. Not only the sale figures are considered but also the days when it is mostly sold and the kind of people who prefer to buy it is considered and then a common pattern is determined. For example, YouTube is a very famous video sharing website where users can upload, share and view videos. To improve their services to the users, they used the data mining technique. On the basis of what kinds of videos the user

views and like, the users are shown the recommended videos. The recommended videos are decided on the pattern that if a group of users like a particular video, then mining is done to find the other videos that user would like. This feature helped the website in terms of views of videos as many videos started getting explored and viewed. Data Mining follows several steps so as to reach the desirable result.
