Open source intelligence is a key component of modern intelligence system, and its analysis is an important part of intelligence work. Among them, the open source text data are most massive and valuable, but are hard to process when they are mainly semi-structured and unstructured data. Therefore, a low-cost automated text information processing method is critical. This paper proposes an open source text intelligence automated processing framework, which is based on distant supervised relation extraction. It automatically generates training data by aligning entities to a remote database, reducing the cost of manual labeling. Moreover, a relation extraction model combining BiGRU network and dual attention mechanism is proposed, which can effectively improve the extraction performance and reduce the influence of noisy data. Finally, an experiment is organized on the Chinese person relation dataset, and the results show that the extraction performance of our model is significantly improved compared to the baseline models. The results show that the model is effective and can support the analysis of open source intelligence information.
