Analysis of Investment Relationships Between Companies and Organizations Based on Knowledge Graph

摘要

Investment relationship investigation is an important part of financial investigation. However, extraction and analysis of investment relationships becomes more difficult since the increment of the number of enterprises, complexity of company structure, and diversity of investment. This paper uses a knowledge graph of companies to find whether investment relationships between two companies and common investors among target companies exist. In this paper, firstly, find investment relationships between two companies by path finding algorithm to check whether investment paths exist between them. Secondly, use Depth First Search algorithm to check whether common investors exist. Thirdly, knowledge graph contains a great number of companies and relationships between them so that it is inefficient and difficult to compute directly from all the companies nodes. To overcome this problem, this paper will use graph compression to decrease the number of nodes to compute.
