This document presents a project that aims to develop an application to provide personalized product recommendations to online shoppers based on their previous preferences and constraints. The objective is to enhance the customer experience on ecommerce sites. A literature review was conducted on topics related to online shopping processes and data mining algorithms. The proposed algorithm will apply techniques like Naive Bayes, Apriori, and K-means to classify and cluster customer data to determine product recommendations. The project will be implemented using tools like Visual Studio and databases to test and validate the recommendation application.

INTRODUCTION Online shopping has emerged as the newest big thing and why not? Its easy. Its safe, and the best of all it saves TIME! Providing personalized product recommendations for shoppers on ecommerce sites has been proven to boost order values, increase customer loyalty and enhance the online shopping experience.
OBJECTIVE The objective is to develop an application that will provide the online shopping customer a specific range of products customized according to their previous preferences and characteristic constraints through a website with high database handling capability and also taking into account their suggestions and reviews and giving them the assurance that their opinion also matters.
LITERATURE SURVEY We researched several papers and studied them thoroughly to understand our topic and decide the path to implement it. There were main 8 papers we selected to draw our work from. They were in 2 broad categories namely, online shopping with its applications and processes Data mining algorithms to analyze the data and extract results
Online Shopping Portal Processes
Data Mining Algorithm Operations
OPEN PROBLEMS AND ISSUES Fickle-mindedness of the customer Customer input Real time nature of searches Accuracy of the characteristic data Multiple entries of same product varying on some characteristic Segmenting feedback based on phrases
NOVELTY AND BENEFITS It acts as a personal shopper. It takes into account both previous searches and current preferences for current real time recommendations simultaneously. Since it gives you the user ratings rather than the reviewer or company ratings so that a realistic idea can be determined not the hyped up image set by the manufacturers. Segregation of feedback text is done on the basis of the complete meaning of the phrase and not just individual words. Eg. Not Bad It is important to take into account the customer feedback as the product is only worth what the customer sees it as.
PROPOSED ALGORITHM As our program is about finding the right product to recommend to the customer based on their previous searches and preferences, we realized that one particular algorithm or method would not be the right approach for us. So we decided to take some of the popular algorithms of data mining and streamline them according to our requirements. Na誰ve-bayes algorithm Apriori algorithm K-means algorithm Soundex Algorithm Etc.
TOOLS AND TECHNOLOGY Microsoft Visual Studio 2012 Ultimate C# with .NET Framework MS Access for database
Characteristic Jabong Flipkart Myntra Snapdeal US View without registration yes Yes yes no Yes Shopping Cart Yes Yes Yes yes No Recently viewed Yes No No No Yes Constraint as per categories yes Yes no No Yes Comparison of Other Existing Approaches/ Solution to the Problem Framed
IMPLEMENTATION LAYOUTS Forms for user interactions were made in visual studio using c# for login, registration, password change, product display and selection, and feedback gathering. DATABASES Synthetic database for products with their characteristics and each users previous visits as well as their choices was created. Also ratings and quality of manufacture is also added in the tables per product. Table is also created for user password and login and also for customer details.
IMPLEMENTATION EXTRACTION CODE For feedback mining real feedback data is extracted from xml file into MS Access database for further analysis using an extraction code in C# ALGORITHMS Na誰ve-Bayes algorithm and K-means are data mining algorithms used for classification and clustering of data. We have implemented it on our synthetic database of online products to classify them as recommendable or not as per each users preferences. We have also implemented Soundex for feedback mining.
TEST PLAN The purpose of testing is quality assurance, verification and validation, or reliability estimation. Unit Testing Component testing Integration testing Validation Testing System Testing
