Abstract
The development of the metaverse ecosystem drives technological innovations and economic benefits, which correlate well with patent technologies. Ontology is crucial for formulating strategies and practices in metaverse technology by providing a clear knowledge map to navigate this complex domain. The proposed methodology aims to discover implicit domain knowledge and construct an ontology, allowing for dynamic and efficient visualization of domain knowledge. Clustering analysis categorizes patent technologies into subdomains, while LDA topic modeling structures knowledge properties into an ontology schema. The study analyzes 1967 metaverse technology patents granted between 2020 and 2022 from the InnovationQ Plus database. The research confirms that metaverse ecosystems encompass multiple international patent classifications (IPCs) and the three advanced technology clusters (i.e., immersive technology, AI-based computing networks, and financial security authentication) with their topics. Recent metaverse patent trends highlight applications in autonomous vehicles, entertainment and advertising, and privacy/security protections. This method is applicable for tracking technology trends across various domains.
期刊介绍:
The aim of World Patent Information is to provide a worldwide forum for the exchange of information between people working professionally in the field of Industrial Property information and documentation and to promote the widest possible use of the associated literature. Regular features include: papers concerned with all aspects of Industrial Property information and documentation; new regulations pertinent to Industrial Property information and documentation; short reports on relevant meetings and conferences; bibliographies, together with book and literature reviews.
