Interactive assignment of topic labels of microblogs

摘要

A microblog is a short text message that usually comprises a topic tag that enables others to locate the microblog. A method of assigning a topic tag to a microblog comprises detecting a topic tag which is pre-assigned to the microblog. The microblog is analysed using a topic modelling technique to identify at least one topic which is related to the microblog. The method compares the pre-assigned topic tag with the topic identified using the topic modelling technique and provides feedback to a user and an indication of whether the pre-assigned topic tag or at least one of the identified topic tags should be assigned to the microblog.
