Abstract

Translation suggestion (TS) models are used

to automatically provide alternative sugges-

tions for incorrect spans in sentences gener-

ated by machine translation. This paper intro-

duces the system used in our submission to the

WMT’22 Translation Suggestion shared task.

Our system is based on the ensemble of differ-

ent translation architectures, including Trans-

former, SA-Transformer, and DynamicConv.

We use three strategies to construct synthetic

data from parallel corpora to compensate for

the lack of supervised data. In addition, we

introduce a multi-phase pre-training strategy,

adding an additional pre-training phase with

in-domain data. We rank second and third on

the English-German and English-Chinese bidi-

rectional tasks, respectively.

1 Introduction

Translation suggestion (TS) is a scheme to simplify

Post-editing (PE) by automatically providing alter-

native suggestions for incorrect spans in machine

translation outputs. Yang et al. (2021) formally

deﬁne TS and build a high-quality dataset with hu-

man annotation, establishing a benchmark for TS.

Based on the machine translation framework, the

TS system takes the spliced source sentence

and

the translation sentence

˜m

as the input, where the

incorrect span of

˜m

is masked, and its output is

the correct alternative

of the incorrect span. The

TS task is still in the primary research stage, to

spur the research on this task, WMT released the

translation suggestion shared task.

This WMT’22 shared task consists of two sub-

tasks: Naive Translation Suggestion and Trans-

lation Suggestion with Hints. We participate

in the former, which publishes the bidirectional

translation suggestion task for two language pairs,

English-Chinese and English-German, and we par-

ticipate in all language pairs.

Our TS systems are built based on several ma-

chine translation models, including Transformer

(Vaswani et al.,2017), SA-Transformer (Yang et al.,

2021), and DynamicConv (Wu et al.,2018). To

make up for the lack of training data, we use par-

allel corpora to construct synthetic data, based on

three strategies. Firstly, we randomly sample a

sub-segment in each target sentence of the golden

parallel data, mask the sampled sub-segment to sim-

ulate an incorrect span, and use the sub-segment

as an alternative suggestion. Secondly, the same

strategy as above is used for pseudo-parallel data

with the target side substituted by machine trans-

lation results. Finally, we use a quality estimation

(QE) model (Zheng et al.,2021) to estimate the

translation quality of words in translation output

sentence and select the span with low conﬁdence

for masking, and then, we utilize an alignment tool

to ﬁnd the sub-segment corresponding to the span

in the reference sentence and use it as the alterna-

tive suggestion for the span.

Considering that there is a domain difference

between the synthetic corpus and the human-

annotated corpus, we add an additional pre-training

phase. Speciﬁcally, we train a discriminator and

use it to ﬁlter sentences from the synthetic cor-

pus that are close to the golden corpus, which we

deem as in-domain data. After pre-training with

large-scale synthetic data, we perform an additional

pre-training with in-domain data, thereby reducing

the domain gap. We will describe our system in

detail in Section 3.

2 Related Work

The translation suggestion (TS) task is an important

part of post-editing (PE), which combines machine

translation (MT) and human translation (HT), and

improves the quality of translation by correcting

incorrect spans in machine translation outputs by

human translators. To simplify PE, some early

scholars have studied translation prediction (Green
