In this talk, I will present several recent research projects in dialog generation and text generation. First, I will attack the problem of automatically selecting a response in an open-domain dialogue, from a list of candidate responses. This is a form of dialogue system which can be modeled as a classification problem. Our main approach is to segment the dialogue context into sub-dialogues through the use of a special discourse parsers, and hence gain better and more efficient representation of the context. Then, I will present a novel problem of clarification question generation for product descriptions. When writing a brief textual description for a product, one may omit certain important details such as the dimensions and certain key features. Our techniques can be used in a writing assistant, that can automatically ask questions about these missing details given a product description. Finally, I will talk about a novel method to do abstractive summarization of text documents. Our method is driven by the intuition that human summarizes a text by first selecting a number of key sentences and then rephrase these sentences. We focus on a new effective way of doing the sentence selection that can achieve state-of-the-art results on the popular CNN-Daily and DUC benchmarks.
