【摘要】：在知识经济时代,日益增强的市场竞争对企业的产品创新能力提出了更高的要求。一个企业能否持续不断地进行产品更新,开发出适合市场需求的新产品,成为决定该企业能否实现持续稳定发展的重大问题。产品创新需要更多跨学科的知识和信息,更复杂的技术支撑和更完善的创新理论。随着互联网的迅猛发展,网上的信息资源越来越庞大,Internet已成为一个巨大便捷的信息资源库,这些信息对灵感的激发,对想象力的扩展非常有帮助,对产品创新思维的影响也更大。本文首先介绍了知识和信息的概念,详细阐述了知识和信息尤其是网络信息资源在产品创新设计中的作用。在介绍网络信息资源的基础上,叙述了当前网络搜索引擎的工作原理,并对元搜索引擎做了详细分析。指出了当前的网络搜索引擎对于计算机辅助产品创新设计获取网络信息存在的不足,提出了面向创新设计的多层次web信息检索系统模型。它包括自然语言搜索、引导式搜索、关键词搜索、分类浏览和随机搜索五种搜索方式,主要功能是使设计人员从紧密到相对宽松的范围内进行资源检索(即从寻找相关设计知识到浏览无直接关系的信息),激发设计人员的创新思维,使之产生新的概念和新颖的设计思路。自然语言搜索是让用户以自然语言的方式表达自己对知识和信息的需求,是有更人性化的搜索方式和拥有更高的查询精度。引导式搜索采用格式化的模式引导用户提出问题进行搜索,方便用户在不能准确表达搜索词时使用,能够帮助用户准确地搜索相关知识和信息。分类浏览建立一种分类链接,能够让设计者方便地浏览和查阅各个方向的权威网站,它包括专利库,专业数据库等,方便用户浏览固定的网络资源和收藏相关的网站。随机搜索通过随机产生的方
[Abstract]:In the era of knowledge economy, the increasing market competition puts forward higher requirements for the product innovation ability of enterprises. Whether an enterprise can continuously update its products and develop new products suitable for market demand has become a major problem that determines whether the enterprise can achieve sustainable and stable development. Product innovation needs more interdisciplinary knowledge and information, more complex technical support and more perfect innovation theory. With the rapid development of the Internet, the information resources on the Internet have become a huge and convenient information resource bank, which is very helpful to inspire inspiration and expand imagination. The impact on product innovation thinking is also greater. This paper first introduces the concept of knowledge and information, and expounds in detail the role of knowledge and information, especially network information resources in product innovation design. Based on the introduction of the network information resources, this paper describes the working principle of the current network search engine, and makes a detailed analysis of the meta search engine. This paper points out the deficiency of the current network search engine for computer aided product innovation design to obtain network information, and puts forward a multi-level web information retrieval system model for innovative design. It includes natural language search, guided search, keyword search, classified browsing and random search. The main function is to enable designers to search resources from close to relatively loose range (from searching for relevant design knowledge to browsing information that is not directly related), and to stimulate designers' innovative thinking. Make it produce new concept and new design idea. Natural language search is to let users express their needs for knowledge and information in the way of natural language. It has a more humanized search method and a higher query accuracy. Guided search uses formatted mode to guide users to ask questions for searching, which is convenient for users to use when they can not express search terms accurately, and can help users to search for relevant knowledge and information accurately. Classification browsing establishes a kind of classification link, which enables designers to easily browse and consult authoritative websites in all directions. It includes patent libraries, professional databases, and so on. It is convenient for users to browse fixed network resources and collect related websites. A square generated by random search.
