IRJET- Online Sequential Behaviour Analysis using Apriori Algorithm
0 likes20 views
This document proposes using the Apriori algorithm to perform online sequential behavior analysis for recommendation systems. It summarizes that the Apriori algorithm can be used to find frequently purchased item sets in customer transaction data and those frequent items can then be recommended. It outlines how the Apriori algorithm works in an iterative manner, generating itemsets of increasing size and calculating their support and confidence. The proposed system would analyze customer browsing and purchase histories to generate product recommendations using this approach.

5. IMPLEMENTATION OF SYSTEM:
The main page consists of Login Portal. After Login the
customer can view categories of Products available. The
customer can select desired category and proceed to
browse the available products. The customer can now
check the listed price of the products. The customer will be
displayed recommended products on the right side and
top-rated products below the main browsing screen.
While browsing the customer can add products to cart
based on their requirement. The cart will store the
products the customer wants to buy. After this the
customer can further browse more products or proceed to
checkout.

6. APPLICATIONS:
The basic objective of this system is to let user have a fair
idea of what a Recommendation system is and how it is
useful for an E-commerce system.
7. FUTURE SCOPE:
Recommendation system holds a strong future in E-
commerce on a web. Given the current working and design
of the proposed systems, there is definitely a place for
future enhancements.
In future works, the algorithm can be extended to web
content mining, web structure mining, etc. The work can
also be extended to extract information from image files.
Lastly, enhancements in the recommendation algorithms
used can help increase the accuracy of the system and
therefore can help towards the research and development
of the topic.
8. CONCLUSIONS:
Recommendation system is a novel interactive technology
for fetching additional data for any business from its
transaction-oriented database of customers and thus
providing different platform of growth to the business. This
system helps the customers to find products which they
want to buy from the site.
Recommendation system gives benefits to customers by
enabling them to find products which they can additionally
buy. Conversely, they also help business by generating
more sales by advertising more products to customers,
increasing their revenue. Recommendation systems are
speedily becoming essential tools in E- commerce on the
web.

With the emergence of data mining and its application the business sector has been benefited in the form of extraction and prediction algorithms. This has helped to mine such sequential data to form behavioural pattern of such data and make predictions. Recommendation System is one such tool that has been used by almost every E-commerce site. This project explores scope of frequent item set based recommendation by implementing Apriori algorithm which is mainly used to find frequently purchased items/products. The key idea behind this recommendation is that any item set that occurs frequently together must have each item (or any subset) occur at least as frequently. Key Words: Recommendation System, Apriori Algorithm, Association Rule, Frequent Item set. 1. INTRODUCTION Recommendation systems have become extremely common in recent years. In definition, goal of a Recommender System is to generate relevant recommendations to a user for items or different products. Recommendation systems usually produce a list of recommendations in one of two ways - through collaborative filtering or content-based filtering. In Collaborative filtering, it approaches building a model from a user's past activities (items that are previously purchased and/or numerical ratings given to those items) as well as similar decisions made by other users; then use that model to projection items (or ratings for items) that the user may have a concern in. The most popular recommendation applications in E- commerce are probably books, research articles, search queries, movies, music, news, social tags, and products in general. There are also recommendation systems for life insurance companies, jokes, experts, restaurants, financial services and Twitter followers. In this work, we are dealing of frequent item set based recommendation using Apriori Algorithm which works on concept of association rules. Example “If a customer purchases shirt then he also buys tie or pants in 70% of the cases”. The algorithm searches out frequently purchased items and those items are then suggested as a recommendation to the customer. 2. EXISTING SYSTEM Today, E-commerce sites use recommendation systems on a large scale to boost their business. The products can be recommended based on the extent of the overall sale with regards to a site, based on the suggestions to the customers, or based upon an analysis of the extra buying behavior of the customer, as a prediction for difficult buying behavior. This methodology is used by retailers all over the world to determine which items are purchased together. Also, they face cold start problem i.e. 1) How to recommend a new user in which case there is no browse history? 2) How to recommend new items which has no purchase history? It also gives recommendations based on the area of interests of the user, customer searches and also suggests products based on it. For e.g. Amazon or Flip cart uses user view data i.e. if any customer or user searches a product from a specific category the system suggests a product form the same category. Also based on the current search by the user, the site recommends products. Every user who visits the site may not buy a product. They can just go through it and based on those real-time search results the site recommend a product. 3. PROPOSED SYSTEM Apriori is designed to operate on databases containing transactions and generate association rules, while using a "bottom up" approach, which means that frequent subsets are extended one item at a time and groups of candidates (the candidate set contains all the frequent k-length item sets) which are tested against the data. The algorithm terminates when no further successful extensions are found. By generating sets of data, we calculate support and confidence of itemsets. We do not calculate support and confidence for itemsets which do not occur together to reduce redundancy of data. The process works in multiple iterations.

Itemsets are not made for products which do not occur together in transaction since their support and confidence value is zero by default. Second Iteration: Another item is added to itemsets from previous iteration keeping in mind that the new item must be associate with both of the items from previous itemset thereby creating a new itemset with three items. Again, the support and confidence of the itemset is calculated. Further Iterations: Depending on the availability of items that can satisfy the same conditions from second iteration, more iterations can exist. Figure 3.1: Itemset Generated in database 4.

It applies an iterative approach or level-wise search where k-frequent itemsets are used to find k+1. This algorithm is best suited for recommendation system since such system generally contain a large amount of data that can be grouped together. Figure 4.3.1: Flowchart of proposed system algorithm
