Abstract
In this modern era, people utilise the web to share information and to deliver services and products. The information seekers use different search engines (SEs) such as Google, Bing, and Yahoo as tools to search for products, services, and information. However, web spamming is one of the most significant issues encountered by SEs because it dramatically affects the quality of SE results. Web spamming’s economic impact is enormous because web spammers index massive free advertising data on SEs to increase the volume of web traffic on a targeted website. Spammers trick an SE into ranking irrelevant web pages higher than relevant web pages in the search engine results pages (SERPs) using different web-spamming techniques. Consequently, these high-ranked unrelated web pages contain insufficient or inappropriate information for the user. To detect the spam web pages, several researchers from industry and academia are working. No efficient technique that is capable of catching all spam web pages on the World Wide Web (WWW) has been presented yet. This research is an attempt to propose an improved framework for content- and link-based web-spam identification. The framework uses stopwords, keywords’ frequency, part of speech (POS) ratio, spam keywords database, and copied-content algorithms for content-based web-spam detection. For link-based web-spam detection, we initially exposed the relationship network behind the link-based web spamming and then used the paid-link database, neighbour pages, spam signals, and link-farm algorithms. Finally, we combined all the content- and link-based spam identification algorithms to identify both types of spam. To conduct experiments and to obtain threshold values, WEBSPAM-UK2006 and WEBSPAM-UK2007 datasets were used. A promising F-measure of 79.6% with 81.2% precision shows the applicability and effectiveness of the proposed approach.
Highlights
Spamdexing or web spamming is described as “an intentional act intended to trigger illegally favourable importance or relevance for a page, considering the web page’s true significance” [1]
For revealing the secret network, we proposed an architecture for data collection that allows us to identify the web pages participating in link farms and to determine the web pages using Facebook search engine optimisation (SEO) groups, SEO forums, and subreddits to improve their rank
We discovered several categories of web spammers during our studies and determined that web spammers are using almost all available platforms for increasing their web pages’ ranks. ey offer backlinks services and provide Facebook likes, Twitter followers, Instagram followers, YouTube subscribers, post boosting, and video views for different social media accounts connected to a specific website for which they want to increase the page rank
Summary
Spamdexing or web spamming is described as “an intentional act intended to trigger illegally favourable importance or relevance for a page, considering the web page’s true significance” [1]. All techniques used by web spammers to change the logical view that a search engine has over the page content are known as content-based web spamming [1]. It is a widespread type of web spamming [8]. Ese are some of the content-based web-spamming techniques used by web spammers to obtain a higher page rank on search engine’s results. WEBSPAM- UK2006 and WEBSPAM-UK2007 datasets are used. e results with a promising F-measure and better precision show the proposed framework’s effectiveness and applicability
