Abstract Based on the semantic analysis of patent specification, the research of potential competitor identification can help enterprises determine strong competitors early on, provide information for strategic decision-making, and enrich the research theory of potential competitors. The background technology and invention content of the patent specification contain rich market and technical information. A three-dimensional preliminary identification framework of potential competitors, including background similarity, solution similarity, and time axis, is constructed based on the patent specification. Based on LDA semantic analysis technology, this study constructs a potential competitor identification process, including four steps: collecting and preprocessing patent data, building a corpus, initially identifying potential competitors, and confirming potential competitors. Taking the field of water environment as an example, the feasibility and effectiveness of the method are proved.
