Therefore, all the options are correct and can be used in web mining.
Step-by-step explanation:
Web mining is a process that employs data mining techniques to discover patterns from the World Wide Web.
When we examine the options presented: information filtering, fraudulent transaction processing, crime fighting on the internet, and click stream analysis, each area actually benefits from the use of web mining.
Information filtering uses web mining to personalize content for users; fraudulent transaction processing can detect potential fraud through pattern recognition; crime fighting on the internet leverages data mining to track and analyze criminal activities; and click stream analysis benefits from examining patterns of user interaction on a website to improve the user experience.
Hence, web mining can be effectively used in all these areas. There is no option where web mining is not applicable among the provided choices.
