写作风格能预测科学欺诈吗?

Is writing style predictive of scientific fraud?

摘要:

最近引入了利用机器学习检测科学欺诈的问题,从一个考虑到各种一般指标的模型中获得了初步的积极结果。结果似乎表明,写作风格是科学欺诈的预测。我们重新审视了这些最初的实验,并表明他们使用的留一检验程序可能会导致对可预测性的略微高估,但简单的模型也可以在一定程度上优于他们提出的模型。我们继续探索更抽象的语言特征,如语言的复杂性和语篇结构,只得到否定的结果。不过,在分析我们的模型时,我们确实看到了一些有趣的模式:例如,科学欺诈包含较少的比较,以及不同类型的对冲和呈现逻辑推理的方式。

英文摘要:

The problem of detecting scientific fraud using machine learning was recently introduced, with initial, positive results from a model taking into account various general indicators. The results seem to suggest that writing style is predictive of scientific fraud. We revisit these initial experiments, and show that the leave-one-out testing procedure they used likely leads to a slight over-estimate of the predictability, but also that simple models can outperform their proposed model by some margin. We go on to explore more abstract linguistic features, such as linguistic complexity and discourse structure, only to obtain negative results. Upon analyzing our models, we do see some interesting patterns, though: Scientific fraud, for examples, contains less comparison, as well as different types of hedging and ways of presenting logical reasoning.
