Abstract :
The customer complaint application via webchat was created to support the Ministry
of Communication and Information in the field of informatics services in Gunungkidul
in conducting services effectively. All customer complaints will be recorded and acted
upon. The existing set of complaints will be classified into several groups, namely
CCTV complaints, application complaints, server complaints, or local network
complaints. The method used for the classification process is the Naïve Bayes Classifier
method. Training data collected with a total of 450 data was used as learning data to
classify complaints. The data was taken from interviews with DISKOMINFO
employees in the field of Gunungkidul Information Services, students, official
employees, and the internet. Data testing is used to test the extent to which the system
successfully classifies correctly. Testing data with a total of 100 data was taken from
the results of surveys conducted using google forms. The results of the study resulted
in an accuracy of 92%. The high accuracy proves that the naïve bayes method can be
used to help classify complaints via webchat sent by users.
