Sequence-to-sequence deep learning has recently emerged as a new paradigm in supervised learning for spoken language understanding. However, most of the previous studies explored this framework for building single domain models for each task, such as slot filling or domain classification, comparing deep learning based approaches with conventional ones like conditional random fields. This project focuses on a holistic multi-domain, multi-task (i.e. slot filling, domain and intent detection) modeling approach to estimate complete semantic frames…
Partner Research Manager in Deep Learning Technology Center (DLTC) at Microsoft Research, Redmond. I work on deep learning for text and image processing (see our JICAI2016 Tutorial or MS internal site) and lead the development of AI systems for dialogue, machine reading comprehension (MRC), question answering (QA), and enterprise applications.
We are hiring Researchers with strengths in ML and NLP, and Software Engineers with rich product experience.
DSSM: We have developed a series of deep semantic similarity models (DSSM, also a.k.a. Sent2Vec), which have been used for many text and image processing tasks, including web search [Huang et al. 2013, Shen et al. 2014], recommendation [Gao et al. 2014a], machine translation [Gao et al. 2014b], and QA [Yih et al. 2015].
Dialogue: We have developed neural network models for social bots trained on Twitter data [project site] and task-completion bots [Lipton et al. 2016; Bhuwan et al. 2016] trained via reinforcement learning using a user simulator.
From 2006 to 2014, I was Principal Researcher at Natural Language Processing Group at Microsoft Research, Redmond. I worked on Web search, query understanding and reformulation, ads prediction, and statistical machine translation.
From 2005 to 2006, I was a research lead in Natural Interactive Services Division at Microsoft. I worked on Project X, an effort of developing natural user interface for Windows.
From 1999 to 2005, I was Research Lead in Natural Language Computing Group at Microsoft Research Asia. I, together with my colleagues, developed the first Chinese speech recognition system released with Microsoft Office, the Chinese/Japanese Input Method Editors (IME) which were the leading products in the market, and the natural language platform for Windows Vista.
Currently, I live with my family in Woodinville, WA.

We introduce a novel approach for automatically generating image descriptions. Visual detectors, language models, and deep multimodal similarity models are learned directly from a dataset of image captions. Our system is state-of-the-art on the official Microsoft COCO benchmark, producing a BLEU-4 score of 29.1%. Human judges consider the captions to be as good as or better than humans 34% of the time.

This project aims to enable people to converse with their devices. We are trying to teach devices to engage with humans using human language in ways that appear seamless and natural to humans. Our research focuses on statistical methods by which devices can learn from human-human conversational interactions and can situate responses in the verbal context and in physical or virtual environments. Natural and Engaging Agents that process human language will play a growing role…

Statistical Parsing and Linguistic Analysis Toolkit is a linguistic analysis toolkit. Its main goal is to allow easy access to the linguistic analysis tools produced by the Natural Language Processing group at Microsoft Research. The tools include both traditional linguistic analysis tools such as part-of-speech taggers and parsers, and more recent developments, such as sentiment analysis (identifying whether a particular of text has positive or negative sentiment towards its focus) Demo URL: http://msrsplatdemo.cloudapp.net/ Service URL:…

The Microsoft Research ESL Assistant is a web service that provides correction suggestions for typical ESL (English as a Second Language) errors. Such errors include, for example, the choice of determiners (the/a) and the choice of prepositions. The web service also provides word choice suggestions from a thesaurus. In order to help the user make decisions on whether to accept a suggestion, the service displays "before and after" web search…

Scalable Language-Model-Building Tool
This scalable language-model tool is used to build language models from large amounts of data. It supports modified absolute discounting and Kneser-Ney smoothing. The tool has been used successfully to build a seven-gram language model on 40 billion words within eight hours.
