Named graph-based knowledge graph time evolution method

The invention provides a named graph-based knowledge graph time evolution method. The method comprises the following steps of: firstly dividing different time periods or time points according to a requirement; adding a named graph for each original triple in knowledge graphs through named graphs, adding triples and corresponding time to different named graphs, so as to obtain a tetrad carrying a time description, wherein the format of the tetrad is (->->, {time}). The knowledge graphs can read different graphs to display a same triple in different times and spaces, so as to realize a time-space evolution effect. 本发明提供种基于具名图的知识图谱时间演化方法，该方法首先，根据需要划分好不同的时间段或时间点。然后，通过具名图来为知识图谱中原有的"三元组"加入个具名图，向不同具名图添加"三元组"和它所对应的时间，得到个携带时间描述的"四元组"，格式为(->->,{time})。知识图谱就可以根据读取不同的图来展示不同时空里的同"三元组"，实现时空演化效果。
