Can machines learn to use a search engine as an interactive tool for finding information?
Climate change communication in the mass media and other textual sources may affect and shape public perception.
We introduce CLIMATE-FEVER, a new publicly available dataset for verification of climate change-related claims.

We investigate a framework for machine reading, inspired by real world information-seeking problems, where a meta question answering system interacts with a black box environment.
We investigate methods to efficiently learn diverse strategies in reinforcement learning for a generative structured prediction problem: query reformulation.
We propose a method to efficiently learn diverse strategies in reinforcement learning for query reformulation in the tasks of document retrieval and question answering.
Our method can obtain improvements also on the setting where a small amount of parallel data for the zero-shot language pair is available.
We analyze the language learned by an agent trained with reinforcement learning as a component of the ActiveQA system [Buck et al., 2017].
The agent probes the system with, potentially many, natural language reformulations of an initial question and aggregates the returned evidence to yield the best answer.
