Thacker, Palak, and Thacker, Chintan presented a review work on web page ranking algorithms in the web mining, the collection of consistent websites and site pages provides essential information to the users. The gradual increase in the quantity of web pages functions as traditional PageRank algorithm requires numerous enhancement and adjustments in a versatile manner [20]. Mebrahtu, A, and Srinivasulu, B, presented an overview of web content mining techniques, tools and relevant tactics to provide spectacular and unpredictable progression of information present on the Internet. The authors have presented the notion of web mining, then provides a complete structure of techniques, strategies, and tactics of web mining and then provide a review of several types of web content mining tools, techniques, and strategic enhancements and complete with the relevant algorithms [21]. Vidya, S, and Banumathy, K, presented a review on web mining concepts, applications, and techniques, the authors explained the entire systematic approach of web mining, and it’s subcategories that includes web content, web usage mining, and web structure mining along with the classification of clustering and association [22]. Siddiqui, A.T, and Aljahdali, S contributed in the research work on the production of E-Commerce Applications via Web Mining Techniques, the authors explained the notion of web mining techniques and their influence on the dimensions of businesses, enterprises, and companies [23]. Lang Chunmin and et al., provided an analysis for the examination of the consumer’s fashion-oriented consumer exposures with the help of web content mining tactics and methodological approaches. The authors identified the merits and demerits of online mass customizations tailored to the experiences gathered by the individual customer or focus groups. Furthermore, cost analysis and estimation were predicted by the authors using different techniques of web content mining starting from the data cleaning process to data validation of clothes and vice versa [24]. Bhat Prashant and et al., proposed a new framework for social media analysis of content mining approaches and discovering patterns of knowledge. The authors reviewed some of the prevailing social media-based web content mining tactics to propose a new modular approach for effective data mining patterns and framework to extract the useful and manageable framework from the web usage data mining aspects [25]. Singh, Satyaveer, and Aswal, Singh Mahendra presented ontology-based learning approaches based on the classification of web mining techniques. The authors focused on the need for analysis of rapid and effective management of constructive ontologies for building a standardized knowledge-based and semantically driven web-based ontology software solution. Furthermore, the authors highlighted a comprehensive overview of various tasks in conjunction with the ontology-based learning methods and frameworks pertaining to the web mining tactics for comparatively analyzing distinct ontological learning-based tasks to overcome problems and provide solutions in devising the ontology from the semi-structured set of website pages [26]. Aartsen Van Brent, and et al., conducted a detailed review and analysis of web usage mining techniques and further prospective research initiatives.
