----------------------------------------------------------------***--------------------------------------------------------------Abstract - Nowadays before making a purchase from an Ecommerce site we firstly browse the online reviews of products posted by the post-purchase customers. Today Ecommerce sites uses trust models based on reputation of each sites. The trust models are computed based on the feedback ratings on E-commerce sites. The main problem that arises during the computation is the “all good reputation problem”.E-commerce sites like Amazon, EBay is highly prone to the “all good reputation problem”. Thus we need to use trust evaluation to compute the feedback ratings obtained from various E-commerce sites. For this we mine each of the feedback comments based on their dimensions and weights.So,in order to mine feedback comments an algorithm is used. Key Words: Aspect mining, LDA, NLP, LEXICAL-LDA
1. INTRODUCTION Before making a purchase from an E-commerce site what we does is we go through each of the product reviews in that particular site. Because online feedback reviews helps us to find the post purchase experiences of products and services. However we know that all the reviews we find in an Ecommerce site may not be genuine. Some reviews we find in an E-commerce site may be fake yet they may be written to appear as authentic. However it is a very tedious task to differentiate between authentic and fake reviews. Our main objective behind the paper is to find or to categorize sellers in an E-commerce site by providing each seller’s trusted profile. In an E-commerce site we can find a huge number of customer reviews. Also we should take into consideration that the reputation scores for each seller’s in an E-commerce site may be very high. Hence it will be difficult for a customer to find a trust worthy sellers. For E-commerce sites like E-bay and Amazon the reputation scores will be very high. So in this paper we consider a buyer’s feedback reviews in free text feedback comments. For this we propose an algorithm called Comm trust in order to mine feedback comments.
