Abstract: Wikipedia is based on the idea that anyone can make edits in order to create reliable and crowd-sourced content. Yet with the cover of internet anonymity, some users make changes to the online encyclopedia that do not align with Wikipedia's intended uses. In this talk, we present different forms of disinformation on Wikipedia including vandalism and spam and introduce the mechanism that Wikipedia implements to protect its integrity such as blocking malicious editors and page protection. Next, we provide an overview of effective algorithms based on the user editing behavior, we have developed to detect malicious editors and pages to protect across multiple languages.
