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.

通过基于 LDA 的专利挖掘探索技术应用:元宇宙本体构建
元数据生态系统的发展推动了技术创新和经济效益的提高,这与专利技术密切相关。本体对于制定元数据技术的战略和实践至关重要,它提供了一个清晰的知识图谱,以便在这个复杂的领域中游刃有余。所提出的方法旨在发现隐含的领域知识并构建本体,从而实现领域知识的动态和高效可视化。聚类分析将专利技术归类为子领域,而 LDA 主题建模则将知识属性结构化为本体模式。该研究分析了创新Q Plus数据库中2020年至2022年间授权的1967项元宇宙技术专利。研究证实,元宇宙生态系统包含多个国际专利分类(IPC)和三个先进技术集群(即沉浸式技术、基于人工智能的计算网络和金融安全认证)及其主题。最近的元宇宙专利趋势突出了在自动驾驶汽车、娱乐和广告以及隐私/安全保护方面的应用。这种方法适用于跟踪各个领域的技术趋势。
