Abstract

Deep learning for NLG and its application for chatbot system

In this talk, we focus on showing the state-of-the-art works on natural language generation(NLG) using deep learning approaches. We will highlight existing works on NLG from the leading natural language processing conferences in 2018. We then present the application of NLG in the chatbot systems. The first part of the tutorial will show the background knowledge on deep learning for natural language processing. The second part will discuss NLG techniques from the basic to the state of the art techniques. The third part will show how NLG techniques are used in spoken dialog systems (i.e. Microsoft's Cortana, Apple's Siri, Amazon Alexa, Google Assistant, and Facebook's M) and Chatbot systems. The final part will give a conclusion with our discussion on the challenging of NLG when exploiting for the Vietnamese language.

Abstract

Vietnamese Neural Language Model for NLP Tasks with Limited Resources

A statistical language model is a probability distribution over sequences of words. Language modeling is used in various computing tasks such as speech recognition, machine translation, optical character and handwriting recognition and information retrieval and other applications. Whereas n-gram is considered as a traditional language model, neural language model has been emerging recently as a means to approximate the probability of a sentence using neural networks and word embeddings. An advantage of a neural language model is that it can be further applied to other NLP tasks where the training datasets may be limited. In this talk, we realize this idea by introducing the usage of a Vietnamese neural model language trained from a large corpus of social media data. When further applying this neural model language with other NLP tasks including entity recognition, spam detection and topic modeling with relatively small training datasets; we witness improved performance achieved, as compared to other existing approaches using deep learning with typical word embedding techniques.
