摘 要:文章构建了基于深度学习的主题资源监测采集模型,并利用深度学习词向量工具word2vec对收集的语料进行深度训练,对采集资源与主题模型进行相似度匹配,通过设定合适阈值来实现自动化监测主题资源。实践证明:基于深度学习的定主题监测方法在海洋战略研究所信息监测系统的应用过程中,在主题资源自动监测的准确性上效果优于传统基于向量空间模型的监测算法,能为专题知识库和领域情报信息监测系统的构建打下坚实的基础。Theme open knowledge resource acquisition is usually realized by intelligence personnel through fixed-source and fixed-point data acquisition. But in the age of big data, the number of open access information resources has increased dramatically. In order to improve the accuracy and recall rate of automatic monitoring and collection of theme-related resources,to reduce intelligence personnel workload, the latest achievements of deep learning technology is introduced in the field of artificial intelligence. A theme resource monitoring and collection model based on deep learning is proposed. The word vector tool word2vec was used to train the collected corpus in depth. Similarity matching is conducted between theme crawler collection resources and theme model. The practice proves that the thematic monitoring method based on deep learning proposed in this paper is applied to the information monitoring system of the institute of ocean strategy. The accuracy of subject resource automatic monitoring is better than that of traditional detection algorithms.
