【摘要】：知识经济的到来,给个人、企业乃至国家都带来了巨大的挑战,只有不断的创新才能应社会的快速发展。知识是人类沟通的一种媒介,创新是人类的一种生存方式。没有知识,就无法创新；离开了创新,社会将无法发展和前进。在现实世界中,知识和信息是极其丰富的,同时又是非常混乱的,对于个人和企业来说,亟待解决的问题是如何从纷繁的知识中获取有用的知识,并且将这些知识科学的表示出来,以满足创新设计的需要。目前中国大部分企业尚未成为技术创新的主体,缺乏完善的知识产权战略；企业进行新产品研发或技术改造时,缺乏快速直接的创新解决方案。本文选取九类林业机械领域的专利(共计200条)作为研究对象和领域知识的主要来源,使用Protege软件对领域知识和TRIZ知识进行本体构建,形成林业机械领域本体和TRIZ本体,并运用基于实例相似度的本体映射算法,完成对林业机械领域本体的映射,消除异构本体；通过进化、继承、包含和相似关系将两种本体相关联,构建了基于林业机械领域本体知识的TRIZ融合架构,分析了融合架构的组成结构、关键技术以及应用过程；运用Jena完成基于本体的语义检索和推理,并将其融入到TRIZ融合架构中,设计开发了基于该架构的原型系统,构建了面向林业机械领域的TRIZ辅助创新平台。本文融合本体、TRIZ方法及语义技术,提出建立一种能够适用于万维网的面向创新设计的语义知识表示方法,辅助用户找到创新设计的方法。通过实例验证表明,本研究能够针对林业机械领域的企业在生产过程中遇到的问题,给出解决问题的领域解,辅助企业在产品设计和工艺设计中实现功能创新和原理创新,可以提高企业技术创新能力和效率。本研究为其它领域遇到类似的问题具有参考价值和指导意义。
[Abstract]:The arrival of knowledge economy has brought great challenges to individuals, enterprises and even countries. Only continuous innovation can meet the rapid development of society. Knowledge is a medium for human communication, innovation is a way of human existence. No knowledge, no knowledge, no knowledge, no knowledge, no knowledge, no knowledge, no knowledge, no knowledge, no knowledge, no knowledge, no knowledge, no knowledge. Without innovation, society will not be able to develop and advance. In the real world, knowledge and information are extremely rich and at the same time very chaotic, for individuals and businesses, The problem to be solved urgently is how to obtain useful knowledge from the complicated knowledge and express it scientifically to meet the needs of innovative design. At present, most enterprises in China have not become the main body of technological innovation. Lack of comprehensive intellectual property strategy; lack of rapid and direct innovative solutions for new product research and development or technological transformation. In this paper, nine kinds of patents in forestry machinery field (200 patents in total) are selected as the main source of research object and domain knowledge. Domain knowledge and TRIZ knowledge are constructed by using Protege software to form domain ontology and TRIZ ontology of forestry machinery. The ontology mapping algorithm based on case similarity is used to complete the mapping of forestry machinery domain ontology and eliminate the heterogeneous ontology. Through evolution, inheritance, inclusion and similarity relation, the two ontologies are related. The TRIZ fusion framework based on ontology knowledge in forestry machinery domain is constructed, and the composition structure, key technology and application process of the fusion framework are analyzed, and the semantic retrieval and reasoning based on ontology are completed by using Jena, and it is integrated into the TRIZ fusion framework. A prototype system based on this architecture is designed and developed, and a TRIZ aided innovation platform for forestry machinery field is constructed. This paper proposes a semantic knowledge representation method for innovative design which can be applied to the World wide Web to assist users to find innovative design. The example shows that the research can solve the problems in the production process of forestry machinery enterprises, and help enterprises to realize function innovation and principle innovation in product design and process design. It can improve the technological innovation ability and efficiency of enterprises. This study has reference value and guiding significance for other fields to encounter similar problems.
