Abstract
A method is provided for deleting a content element of a chat history lacking long-term relevance. The method includes receiving a content element, assigning the content element to a topic, determining a relationship index value for the content element to the topic using a validity value, which is a function of an access rate and a credibility index value. The method also includes comparing the relationship index threshold value for the topic of a first chat user, where the content element has been generated by a second chat user, and linking the content element of the second chat user to the topic in the chat history of the first user. The content element is deleted if it is not linked to any other chat history of another chat user of the plurality of chat users, thereby saving long-term chat storage space.
