onomot, a sentiment analysis mobile application, is mainly developed to determine the sentiment of Bangla texts. With the help of this application a user can analyze a text to determine its polarity, subjectivity and the emotion behind it.

The subjectivity of the text is defined using the two classes: subjective and objective.
Actually, subjectivity describes the type of information in the text, including facts and personal opinions.
In addition, the user can also view the emotion of the given text and six categories will be used to classify the texts emotions such as, happy, fear, anger, sadness, surprise and neutral. With this emotion analysis, the user can identify what emotion the text is actually expressing.
