Irony is defined as the expression of one's meaning by using language that normally signifies the opposite, typically for humorous or emphatic effect. In the textual context, it can be considered as a specific type of opinion mining problem. However, due to the nature of the problem, it is generally more challenging to detect. Irony detection is useful to understand the semantics of a text. It also helps improving the accuracy of many other text mining tasks. In this paper, we study the irony detection problem on Turkish informal texts. In the literature there are several solutions proposed mostly for English texts. However, the number of studies on Turkish texts is very limited. The reason for using informal text is that ironic expressions are seen more frequently in informal communication media such as blogs, social media posts. Previously, performance of conventional supervised learning based solutions, such as Naive Bayes Classifier and SVM, on Turkish texts have been studied. In this work, we investigate the performance of neural network based models in comparison to conventional supervised learning models.
