By comparison different features of product and different domain, companies, product vendors focus on improving the feature of product that is not popular.

At a recent time, the web has become a valuable source of online consumer review however as the number of reviews is growing in high speed. It is infeasible for user to read all reviews to make a valuable or satisfying decision because the same features, people can write it contrary words or phrases. To produce a useful summary of domain synonyms words and phrase, need to be a group into same feature group. We focus on feature-based opinion mining problem and this paper mainly studies feature based product categorization from the number of users-generated review available on the different website. First, a multi-feature segmentation method is proposed which segment multi-feature review sentences into the single feature unit. Second part of speech dictionary and context information is used to consider the irrelevant feature identification, sentiment words are used to identify the polarity of feature and finally an unsupervised clustering based product feature categorization method is proposed. Clustering is unsupervised machine learning approach that groups feature that have a high degree of similarity in a same cluster. The proposed approach provides satisfactory results and can achieve 100% average precision for clustering based product feature categorization task. This approach can be applicable to different product.

Merchants selling products on the Web often ask their customers to share their opinions and hands-on experiences on products they have purchased. This is not only true for organizations but also true for individuals. Our beliefs and perceptions of reality, and the choices we make, are, to a considerable degree, conditioned upon how others see and evaluate the world. For this reason, when we need to make a decision we often seek out the opinions of others. Unfortunately, reading through all customer reviews is difficult, especially for popular items, the number of reviews can be up to hundreds or even thousands. This makes it difficult for a potential customer to read them and make an informed decision. Thus a compressed and precise opinion list is what a user would generally desire. The contents available on the Web are not in the standard format. The idea is to classify these contents as formal and informal. The type of algorithm used is linguistic. It incorporates grammatical and other knowledge of the language which helps in understanding the text, thus trying to improve the mining approach to mine product features and their opinions from Web opinion sources for formal as well as for informal text.
