摘要:

提出了一种股票预测方法。在特征提取方面,我们提取了股票相关新闻的除股价外的特征。我们首先根据经验选取了一些种子词,它们分别代表好消息和坏消息。然后我们提出了一种优化方法,并计算所有的词的正极。在此基础上,我们根据新闻话语的积极极性来构建新闻的特征。考虑到连续性新闻效应和连续性股票价格,我们提出了一个递归神经网络模型来帮助预测股票价格。实验结果表明,与基于价格特征的SVM分类器相比,该方法在股票预测准确率上提高了5%以上。

英文摘要:

This paper proposed a method for stock prediction. In terms of feature extraction, we extract the features of stock-related news besides stock prices. We first select some seed words based on experience which are the symbols of good news and bad news. Then we propose an optimization method and calculate the positive polar of all words. After that, we construct the features of news based on the positive polar of their words. In consideration of sequential stock prices and continuous news effects, we propose a recurrent neural network model to help predict stock prices. Compared to SVM classifier with price features, we find our proposed method has an over 5% improvement on stock prediction accuracy in experiments.
