However, there is not much SA done on Malay Language, especially on its dialect in social media form. The research presented in this paper aims to perform SA on one of Malay’s Dialect, Sabah
Language. Sabah Language which does not have fix spelling as well as having unstructured form will pose difficulty to the SA performed.

The highest accuracy of the classification is 85.10 %, whereby the classification implements SL expansion, pre-processing stage and perform switch negation with Simple Polarity Score Assignation and Bias-Aware Thresholding method to the SA performed.
