XML is a (71) language for documents containing (72) information.
Structured information contains both content(words, pictures, etc.)and some indication of what role that content plays(for example, content in a section heading has a different meaning from content in a footnote, which means something different than content in a figure caption or content in a database table, etc.). Almost all documents have some structure.
A markup language is a (73) to (74) structures in a document. The XML specification defines a standard way to add markup to (75) .

在由许多项目组成的大型工程中，用顶点表示项目，有向边表示项目之间开始的先后秩序关系，这种用顶点表示活动的图称为AOV网络，其常用的一种存储结构是 (15) 。
为规划整个工程的实现，通常要对上述的顶点进行 (16) 排序，据此可获得项目的 (17) 序列。但并不是所有图都能获得这样的系列，如 (18) 图就不能获得这种序列。因为在这种情况下，所体现的先后关系不是 (19) 。

Data mining is an (66) research field in database and artificial intelligence. In this paper, the data mining techniques are introduced broadly including its producing background, its application and its classification. The principal techniques used in the data mining are surveyed also, which include rule induction, decision (67) , artificial (68) network, genetic algorithm, fuzzy technique, rough set and visualization technique. Association rule mining, classification rule mining, outlier mining and clustering method are discussed in detail. The research achievements in association rule, the shortcomings of association rule measure standards and its (69) , the evaluation methods of classification rules are presented. Existing outlier mining approaches are introduced which include outlier mining approach based on statistics, distance-based outlier mining approach, data detection method for deviation, rule-based outlier mining approach and multi-strategy method. Finally, the applications of data mining to science research, financial investment, market, insurance, manufacturing industry and communication network management are introduced. The application (70) of data mining are described.
