Indonesian text preprocessing is still very limited and requires tools that can help Indonesian researchers to conduct research in the field of text mining in Indonesian, especially on Twitter. Preprocessing needed for text mining processes such as deleting @ notation; Http; stop words; normalize acronym words, slang words, emoticons; and Indonesian stemming. Gataframework besides providing an OPP-based PHP framework, it also provides text mining preprocessing tools to support those needs. The results of Gataframework text mining preprocessing output can be combined with other tools, one of which is Rapidminer. Gataframework also features a web services API that can be connected with other applications. Since 2018, many studies related to Text Mining have begun to use Gataframework as an alternative tool in the preprocessing stage. The results of the use or quality of this tool are assessed by the Likert evaluation model and the Functionality, Usability, Reliability, Performance, Supportability (FURPS) is known as a model for classifying method which has the parameters Functionality, Usability, Reality, Performance, and Supportability. Based on Gataframework users assessment of 21 respondents, the results were Functionality (87.62%), Usability (85.71%), Reality (85.71%), Performance (80.95%), and Supportability (85.71%) while the average value of the overall parameters was 85.14 %, which means very good.
