adts
data abstraction
Examples
- Application component layer envelops the parallel algorithms of matrix - vector operation to offer users high - level interfaces ; the other three layers implement data abstraction 、 data partition and parallel mechanism respectively , and every layer has specific class and interface definition
其中应用组件层把矩阵向量运算的并行算法封装成类组件,为用户提供了高层次的接口;另外三层分别实现数据抽象、数据划分和并行机制支持三方面功能,每一层都有具体的类组件和明确的接口定义。 - This essay first dicussed the key steps of preprocessing in web log mining , which include data abstract , data cleaning , user and session identification and path completion etc . especialy we proposed the algorithm of the web log data preprocessing include frame page . and secondly we discussed the technology of building an adaptive web site , include log data cluster mining , user visiting pattern learning , site structure transformation and presentation etc . ; and we proposed indual user log visiting pattern , user model onling learning algorithm , index pages synthesising algorithm , site structure transformation and presentation algorithm and so on
本论文首先讨论了web日志挖掘预处理中的各步骤：数据抽象、数据清洗、用户与会话识别、访问路径补全，给出了每一步骤的算法实现；并特别讨论了含有frame页的日志数据预处理过滤算法。其次讨论了构建自适应站点技术，包括日志数据聚类挖掘、用户访问模式学习、站点结构转化与呈现等；提出了单用户日志访问模型，给出了用户模型在线学习算法、索引页面综合算法、站点结构转化及呈现算法等。
