摘　　要：为了改善框架排歧模型的性能,区别于传统分类算法人工提取特征的做法,直接从语料中的例句出发,使用神经网络模型给出了一种框架表示学习的算法,并将学习到的框架表示向量用于框架排歧任务,显著提升了框架排歧的性能。该算法充分利用CFN中例句库、词元库,基于hinge-loss的神经网络,学习到能最大区别正确框架与错误框架的框架表示向量。此外,还使用WSABIE算法学习到目标词及其上下文的表示向量,排歧时以上下文表示向量与框架表示向量做余弦夹角来判决。在CFN中88个有歧义的词元上进行3组2折交叉验证(3×2 BCV)实验,框架排歧精度最好达到72.52%,t-检验结果表明该方法性能显著高于其他框架排歧方法。In order to improve the performance of frame disambiguation model,this paper used a neural network model to learn frame representation based on sentences in corpus different from the traditional classification algorithm extracting features manually,and employed the learned frame representation on the frame disambiguation task,which significantly improved the performance of the task.Making full use of the CFN example sentence database and being based on the hinge-loss neural network,the algorithm learnt the frame representation that could distinguish the correct frame from the error frame in the largest degree.This paper also used the WSABIE algorithm to learn the representation vector of the context of the target word,and finally used the cosine distance between the context representation vector and the frame representation vector to make a decision for the task.Experiment performed three sets of two-fold cross-validation(3×2 BCV)on 88 ambiguous words in CFN,and the best accuracy of frame disambiguation reach to 72.52%.The t-test results show that the performance of the proposed method is significantly higher than other frame disambiguation methods.
