基于知识图谱的智能投资决策 (Intelligent Investment Decision Based on Knowledge Graph)

Chinese Abstract: 如何能将海量非结构化数据为投资所用，从海量的新闻中挖掘有用的信息，对于投资决策至关重要。本文研究金融知识图谱的自动构建，把多源数据，包括结构化数据、半结构化数据以及非结构化数据，整合在一起，将金融市场错综复杂的关系以知识图谱的方式刻画。在此基础上，进一步研究基于知识图谱的关联实体挖掘，解决财经新闻与股票实体的对应影响关系识别问题。本文最后设计实验，模拟真实投资策略进行回测，取得了较高的超额收益，验证了本文算法的有效性。
