摘要:

本次提交调查替代机器学习模型预测HTER分数的句子水平。而不是直接预测HTER分数,我们建议一个模型,联合预测的4个不同的编辑后操作,然后用于计算HTER分数的量。这也提供了在计算HTER分数之前校正无效(例如负)预测值的可能性。在没有任何特征探索的情况下,具有4个输出的多层感知器在基线上产生了小但显着的改进。

英文摘要:

This submission investigates alternative machine learning models for predicting the HTER score on the sentence level. Instead of directly predicting the HTER score, we suggest a model that jointly predicts the amount of the 4 distinct post-editing operations, which are then used to calculate the HTER score. This also gives the possibility to correct invalid (e.g. negative) predicted values prior to the calculation of the HTER score. Without any feature exploration, a multi-layer perceptron with 4 outputs yields small but significant improvements over the baseline.
