In Spike Jonze’s futuristic film “Her”, Theodore,
a lonely writer, forms a strong emotional bond with Samantha, an operating
system designed to meet his every need. Samantha can carry on seamless
conversations with Theodore, exhibits a perfect command of language,
and is able to take on complex tasks. She filters his emails for importance,
allowing him to deal with information overload, she proactively arranges
the publication of Theodore’s letters, and is able to give advice
using common sense and reasoning skills.
In this talk I will
present an overview of recent progress on learning natural language
interfaces which might not be as clever as Samantha but nevertheless
allow uses to interact with various devices and services using everyday
language. I will address the structured prediction problem of mapping
natural language utterances onto machine-interpretable representations
and outline the various challenges it poses. For example, the fact
that the translation of natural language to formal language is highly
non-isomorphic, data for model training is scarce, and natural language
can express the same information need in many different ways. I will
describe a general modeling framework based on neural networks which
tackles these challenges and improves the robustness of natural language
interfaces.
