Topic modeling is an unsupervised machine learning method that analyzes text data and determines cluster words for a set of documents. Topic classification is a supervised machine learning method. The textual data is labeled beforehand so that the topic classifier can make classifications based on patterns learned from labeled data.
At this point, you only consider the just computed feature vectors (one vector per document) and run a clustering algorithm on then these vectors.

I would like to know that how to use unsupervised approach to exract pattern from the text data. I have data set about the description of the product in the form of title,short and long description. My goal is to find the value of product attribute using the description available. The value which i am trying to find is present in the descripton.
Text classification is a problem where we have fixed set of classes/categories and any given text is assigned to one of these categories. In contrast, text clustering is the task of grouping a set of unlabeled texts in such a way that texts in the same group (called a cluster ) are more similar to each other than to those in other clusters.
