Discovering technology opportunities from the opinion of users can promote successful technological development by satisfying the needs of users. However, although previous approaches using opinion mining only have classified various needs of users into positive or negative categories, they cannot derive the main reasons for their opinion. To solve this problem, this research proposes an approach to exploring technology opportunity by structuring user needs with a concept of opinion trigger of objects and functions of the technology-based products. To discover technology opportunity, first, an opinion trigger is identified from review data using Naïve Base classifier and natural language processing. Second, the opinion triggers and patent keywords that have a similar meaning in context are clustered to discover the needs of the user and need-related technology. Then, the sentimental values of needs are calculated through graph-based semi-supervised learning. Finally, the needs of the user are classified in resolving the problem of vacant technology to discover technology opportunity. Then, an R&D strategy of each opportunity is suggested based on opinion triggers, patent keywords, and their property. Based on the concept of opinion trigger-based methodology, a case study is conducted on automobile-related reviews, extracting the customer needs and presenting important R&D projects such as an extracted need (cargo transportation) and its R&D strategy (resolving contradiction). The proposed approach can analyze the needs of user at a functional level to discover new technology opportunities.
从用户意见中发现技术机会可以通过满足用户的需求来促进成功的技术发展。然而,尽管之前使用意见挖掘的方法仅将用户的各种需求分为积极或消极类别,但它们无法推导出其意见的主要原因。为了解决这个问题,本研究提出了一种通过构建用户需求的方法来探索技术机会,该方法的概念是基于技术产品的对象和功能的意见触发。为了发现技术机会,首先,使用朴素贝叶斯分类器和自然语言处理从评论数据中识别出意见触发词。其次,将具有相似上下文含义的意见触发词和专利关键词聚类,以发现用户需求和需求相关技术。然后,通过基于图的半监督学习计算需求的情感值。最后,通过分类用户的需求来解决空缺技术问题,从而发现技术机会。然后,根据意见触发词、专利关键词及其属性,为每个机会制定研发策略。基于意见触发词的方法概念,本文对汽车相关评论进行了案例研究,提取了客户需求,并提出了重要的研发项目,例如提取的需求(货物运输)及其研发策略(解决矛盾)。所提出的方法可以在功能级别分析用户的需求,以发现新的技术机会。
