Automatic Fact-guided Sentence Modification
Online encyclopediae like Wikipedia contain large amounts of text that need
frequent corrections and updates. The new information may contradict existing
content in encyclopediae. In this paper, we focus on rewriting such dynamically
changing articles. This is a challenging constrained generation task, as the
output must be consistent with the new information and fit into the rest of the
existing document. To this end, we propose a two-step solution: (1) We identify
and remove the contradicting components in a target text for a given claim,
using a neutralizing stance model; (2) We expand the remaining text to be
consistent with the given claim, using a novel two-encoder sequence-to-sequence
model with copy attention. Applied to a Wikipedia fact update dataset, our
method successfully generates updated sentences for new claims, achieving the
highest SARI score. Furthermore, we demonstrate that generating synthetic data
through such rewritten sentences can successfully augment the FEVER
fact-checking training dataset, leading to a relative error reduction of 13%.Comment: AAAI 202
Deep Learning for Text Style Transfer: A Survey
Text style transfer is an important task in natural language generation,
which aims to control certain attributes in the generated text, such as
politeness, emotion, humor, and many others. It has a long history in the field
of natural language processing, and recently has re-gained significant
attention thanks to the promising performance brought by deep neural models. In
this paper, we present a systematic survey of the research on neural text style
transfer, spanning over 100 representative articles since the first neural text
style transfer work in 2017. We discuss the task formulation, existing datasets
and subtasks, evaluation, as well as the rich methodologies in the presence of
parallel and non-parallel data. We also provide discussions on a variety of
important topics regarding the future development of this task. Our curated
