| Data gathering and processing requires access to data and has several inherent issues, including information overload and data errors. Once data is collected, it will need to be transformed into a format that can be effectively used by both human and computer analyzers. Manual or computer-generated visualizations tools may be mapped from the data, including network charts. Several algorithms exist to help with analysis of data – Dijkstra’s algorithm, breadth-first search, and depth-first search. | | Data gathering and processing requires access to data and has several inherent issues, including information overload and data errors.

− | 在得到数据后,需进行数据的收集和处理,但此过程存在一些固有的问题,包括信息超载和数据错误等。在数据被收集后,它将转换成一种人和计算机分析程序都能有效使用的格式。之后基于数据,人工或计算机生成的可视化工具可以进行作图,如网络图。目前有几种算法可以帮助进行数据分析-Dijkstra算法,广度优先搜索和深度优先搜索。

| Klerks categorized link analysis tools into 3 generations. The first generation was introduced in 1975 as the Anacpapa Chart of Harper and Harris. This method requires that a domain expert review data files, identify associations by constructing an association matrix, create a link chart for visualization and finally analyze the network chart to identify patterns of interest. This method requires extensive domain knowledge and is extremely time-consuming when reviewing vast amounts of data. | | Klerks categorized link analysis tools into 3 generations.

− | Klerks把链接分析工具分为三代。第一代是由哈珀和哈里斯在1975年引入的,阿纳卡帕图。这种方法需要一个领域内的专家来审查数据文件,通过构造一个关联矩阵来识别关联,然后创建一个可视化的链路图,最后通过分析网络图来识别有意义的模式。这种方法需要广泛的领域知识,但因为要人工审查大量数据,所以非常耗时。

| In addition to the association matrix, the activities matrix can be used to produce actionable information, which has practical value and use to law-enforcement. The activities matrix, as the term might imply, centers on the actions and activities of people with respect to locations. Whereas the association matrix focuses on the relationships between people, organizations, and/or properties. The distinction between these two types of matrices, while minor, is nonetheless significant in terms of the output of the analysis completed or rendered. | | In addition to the association matrix, the activities matrix can be used to produce actionable information, which has practical value and use to law-enforcement.

− | 除了关联矩阵外,活动矩阵还可用于生成可操作的信息,对执法具有实用价值和使用价值。活动矩阵,正如这个术语可能暗示的那样,集中于人们相对于地点的行动和活动。而关联矩阵关注的是人、组织和 / 或属性之间的关系。这两类矩阵之间的区别虽然很小,但就已完成或提供的分析的输出而言却很重要。
