Abstract: We have developed a large-scale intent detection method for our Turkish conversation system in banking domain to understand the problems of our customers. Recent advancements in natural language processing(NLP) have allowed machines to understand the words in a context by using their low dimensional vector representations a.k.a. contextual word embeddings. Thus, we have decided to use two language model architectures that provide contextual embeddings: ELMo and BERT. We trained ELMo on Turkish corpora while we used a pretrained Turkish BERT model. To evaluate these models on an intent classification task, we have collected and annotated 6453 customer messages in 148 intents. Furthermore, another Turkish document classification dataset named Kemik News are used for comparing our method with the state-of-the-art models. Experimental results have shown that using contextual word embeddings boost Turkish document classification performance on various tasks. Moreover, converting Turkish c haracters to English counterparts results in a slightly better performance. Lastly, an experiment is conducted to find out which BERT layer is more effective to use for intent classification task. (More)
