Clustering, in one sentence, is the extraction of natural groupings of similar data objects hierarchical clustering is the hierarchical decomposition of the data based on group similarities divisive clustering uses a top-down approach, wherein all data points start in the same cluster you can then use a parametric clustering algorithm. Mining the webpage is the predominant technique to grab the data from the internet it is the extracting job from the web pages in either supervised or unsupervised unsupervised extraction extracts more irrelevant data than the relevant and it fails to eliminate the data redundancy the proposed. Clustering approach, which use the semantic relation between documents, which reduces the time complexity it identifies the relations and concepts in a document and also computes the relation score has presented a vision-based approach for deep web data extraction, where the deep web contents. The corresponding unsupervised procedure is known as clustering, and involves grouping data into categories based on some measure of inherent similarity or distance often, the individual observations are analyzed into a set of quantifiable properties, known variously as explanatory variables or features.
