Summary
This paper propose a method for automatic response completion by considering mainly two factors:
1) The language used in responses (By using Language Model[LM](bigram model & trigram model(both back-off to unigram)))
2) The specific context provided by the original message.
The author used the following things to model the part.
[TM]Methods In Ritter et. al 2010, Data-Driven Response Generation in Social Media, which is to use a translation model to do alignment between stimulus(source) and the response(target). [IBM-Model1]
[Selection model]To select a token in stimulus uniformly at random.
[Topic model]First learn a topic model over conversations in the training data using LDA. Then identify the most likely topic of the conversation based on s, and expect responds� to be generated from this topic.
The author used a linear combination to mixture these two factors (models).
