This paper presents the CUNLP submission for the NLP4IF 2019 shared-task on FineGrained Propaganda Detection. Our system finished 5th out of 26 teams on the sentence-level classification task and 5th out of 11 teams on the fragment-level classification task based on our scores on the blind test set. We present our models, a discussion of our ablation studies and experiments, and an analysis of our performance on all eighteen propaganda techniques present in the corpus of the shared task.

An improved parser for data-oriented lexical-functional analysis
我们提出了一个LFG-DOP解析器,它使用片段从LFG注释的句子来解析新的句子。在Verbmobil和Homecentre语料库上的实验表明:(1)Viterbi n best搜索比MonteCarlo搜索快100倍,而两者都达到了相同的精度;(2)对于LFG-DOP,DOP假设的分析精度随着片段大小的增加而增加;(3)LFG-DOP的相对频率估计比折扣频率估计性能差;(4)LFG-DOP的性能明显优于Tree-DOP,仅在树结构上进行评价。
