【摘要】：随着教育信息化的逐步完善，教育资源在发挥教育信息化的优势、提高教学质量等方面所起的作用越来越大。作为教育技术学的一个重要研究领域，教育资源建设是教育信息化的基础。目前，因特网和多媒体技术的蓬勃发展，使得网络上的多媒体教学资源，特别是Flash动画资源，变得日益丰富，，Flash动画资源成为教育资源建设的重要来源，越来越受到人们的重视。 Flash动画资源以其自身形象、直观、可交互等特点在教学中发挥着重要作用，伴随技术的进步，网络用户想要在互联网中快速准确的查找适宜的Flash动画资源却变得难上加难，主要是因为网络中充斥着大量不规范的信息，有用的Flash动画资源淹没在杂乱的网络资源环境中，难以起到其应有的作用。为了满足不同层次用户的学习需要，促进数字化学习资源库建设，建立专业Flash动画资源搜索引擎就显得尤为重要，而网络Flash动画资源搜索器是搜索引擎的关键，因此，网络Flash动画资源搜索方法研究成为一项越来越重要的任务。论文从教育资源建设出发，这是教育技术的一个重要研究领域，探究Flash动画的特点并总结出Flash在网络中的10种存在形式，确定研究网络Flash动画搜索方法的必要性；通过分析网页特点，设计提取脚本文件的方法；通过分析Flash动画在页面中的存在形式以及总结其特点，获得Flash动画资源在网络中的分布情况，设计提取脚本中Flash地址的方法。本研究主要做了四大工作：第一，按照一定原则找寻种子网站，分析网站首页源代码，总结出Flash动画在网络中的存在形式；第二，按照之前总结的存在形式，人工统计种子网站首页中出现的存在形式；第三，在前人工作的基础上，开发能够提取脚本中Flash地址的搜索器，要设计出高性能搜索方法，必须进行页面解析、脚本的提取和解析等预处理工作，搜索器的设计包括数据库设计和搜索方法设计，数据库设计是基础，搜索方法设计是核心；第四，根据几种存在形式进行网络Flash动画地址的分类提取。论文利用的开发工具为Visual C++程序，在Windows操作系统中实现Flash的下载，最终达到完善教学资源库的目的。实验结果表明，脚本文件中也存在数目较多的Flash动画资源，对其进行下载可以提高搜索器的可下载率，对网络Flash动画资源进行搜索方法研究，可以更加深入得研究动态网页中的Flash动画资源，下载更多质量更高的Flash动画资源。
[Abstract]:With the gradual improvement of educational informatization, educational resources play a more and more important role in giving play to the advantages of educational informatization and improving teaching quality. As an important research field of educational technology, the construction of educational resources is the foundation of educational informatization. At present, with the rapid development of Internet and multimedia technology, multimedia teaching resources, especially Flash animation resources, have become increasingly rich and become an important source of educational resources construction, and people pay more and more attention to them. Flash animation resources play an important role in teaching because of their own image, intuition and interactivity. With the development of technology, it becomes more difficult for network users to find suitable Flash animation resources quickly and accurately in the Internet. The main reason is that the network is filled with a lot of non-standard information, and the useful Flash animation resources are submerged in the messy network resources environment, so it is difficult to play its due role. In order to meet the learning needs of users at different levels and promote the construction of digital learning resource base, it is particularly important to establish a professional Flash animation resource search engine. The Flash animation resource searcher is the key of the search engine. The research of Flash animation resource search method has become a more and more important task. This paper starts from the construction of educational resources, which is an important research field of educational technology, explores the characteristics of Flash animation, sums up 10 forms of Flash in the network, and determines the necessity of researching the search method of Flash animation on the network. By analyzing the characteristics of web pages, the method of extracting script files is designed. By analyzing the existing form of Flash animation in the page and summarizing its characteristics, the distribution of Flash animation resources in the network is obtained, and the method of extracting Flash addresses from scripts is designed. This study has done four main work: first, according to certain principles to find the seed site, analyze the source code of the website home page, summed up the existence of Flash animation in the network form; second, according to the previous summary of the existence form, Third, on the basis of previous work, we develop a searcher that can extract the Flash address from the script. In order to design a high performance search method, we must parse the page. The design of searcher includes database design and search method design, database design is the basis, search method design is the core. According to several forms of existence, the network Flash animation address classification extraction. The development tool used in this paper is Visual C program, which can download Flash in Windows operating system, and finally achieve the goal of perfecting teaching resource library. The experimental results show that there are many Flash animation resources in the script file. Downloading them can improve the downloadable rate of the searcher. The search method of the Flash animation resource on the network is studied. Flash animation resources in dynamic web pages can be studied more deeply and more Flash animation resources with higher quality can be downloaded.
