Abstract. Based on the epidemic situation in recent years, it has become an urgent need to study how to use many open-source or existed geographical names to evaluate the quality of newly produced geographical names. By analysing the quality characteristics of geographical names data, we can find the key quality elements of geographical names data. We obtained a method of using multi-source data to evaluate newly produced geographical names. This method based on adaptive weight distribution of multi-source data. This method can not only evaluate the whole quality of geographical names, but also grade the specific quality of geographical names. The experiment shows that this method is effective and has strong reference for users and producers.
