基于Web的数据挖掘

Data mining for Web

万维网的出现使计算机拥有海量的信息资源,而其中蕴含的知识却未能得到充分的应用,为此Web挖掘技术成为一项重要的研究课题.在深入分析Web上数据信息的特点基础上,着重从功能的角度给出一种用于Web数据挖掘的过程框架,并介绍了伴随数据挖掘的进行,相应的数据信息从web数据到知识模式的演进过程.利用这些Wed挖掘技术可有效挖掘信息.

The application of world wide web has enriched the computer with floods of information. But not all the knowledge has been fully used yet. So, web mining technology comes into being and develops rapidly.The features of the data are analyzed based on the internet that is distinguished from the database data. A process frame for the data mining basedon web was introduced according to its function. The development of data from raw data into useful knowledge is illustrated.
