Speech Acts Classification of Persian Language Texts Using Three Machine Learning Methods

The objective of this paper is to design a system to classify persian speech acts. the driving vision for thiswork is to provide intelligent systems such as text to speech, machine translation, text summarization, etc. that aresensitive to the speech acts of the input texts and can pronounce the corresponding intonation correctly. seven speechacts were considered and 3 classification methods including (1) naive bayes, (2) k-nearest neighbors (knn), and (3)tree learner were used. the performance of speech act classification was evaluated using these methods including 10-fold cross-validation, 70-30 random sampling and area under roc. knn with an accuracy of 72% was shown tobe the best classifier for the classification of persian speech acts. it was observed that the amount of labeled trainingdata had an important role in the classification performance.
