A content filter that hides any user-defined topics on all web pages.
The internet consists of a range of different undesired information. Besides advertising or spam there is also other content, which specific users do not ant to read about. While some do not want to see spoilers about the last episode of Game of Thrones, others may watch the finals of the European Championship one day later and therefore do not want to be informed about the result. Apart from that, there is a lot of annoying and uninteresting information as well, for example news about the private life of some celebrities. We introduce a web filter that takes undesired topics of the user as input and finds related terms using Wikidata. After applying our filtering algorithm, unwanted content is hidden and the user can decide to unhide it, if he wants to see it anyway. Our system managed to hide nearly 90% of chosen undesired topics of different types on 200 web pages. By only considering topics of specific types the system was able to filter 97% of the unwanted content.
