摘要:

我们建议将文本分类过程建模为顺序决策过程。在这个过程中,智能体学习将文档分类为主题,同时顺序阅读文档句子,并学习在阅读足够的信息进行决策时立即停止。所提出的算法是基于一个模型化的文本分类作为一个马尔可夫决策过程和学习使用强化学习。在四个不同的经典单标记语料库上的实验表明,该方法在大训练集上的性能优于经典SVM方法,而在小训练集上的性能更好。此外,该模型自动调整其阅读过程,以适应所提供的训练信息的数量。

英文摘要:

We propose to model the text classification process as a sequential decision process. In this process, an agent learns to classify documents into topics while reading the document sentences sequentially and learns to stop as soon as enough information was read for deciding. The proposed algorithm is based on a modelisation of Text Classification as a Markov Decision Process and learns by using Reinforcement Learning. Experiments on four different classical mono-label corpora show that the proposed approach performs comparably to classical SVM approaches for large training sets, and better for small training sets. In addition, the model automatically adapts its reading process to the quantity of training information provided.
