pajek时间网络使用方法.doc

pajek时间网络使用教程时间网络（temporal network）分为两种类型一种是Time Events，在某个时间点发生改变；另一种是time intervals，在某个时间段网络状态维持不变。文件后缀.tim。1 .net文件显示时间网络以lin_rel4.NET文件为例 该文件是以时间延续1.1 读文件 File/Network/Read-lin_rel4.NET1.2 生成时间网络Network/Temporal Network/Generate in Time各参数含义： All Generate all networks in specified times. 生成指定时间所有网络 Only Different Generate network in specified time only if the new network will differ in at least one vertex or line from the last network which was generated. 与上次网络相比发生变化时生成网络 Interval Generate network with vertices and lines present in selected interval 在选定的时间间隔生成网络l 此处我们选择第二项，各设置参数如下可以看到Network文件框中生成了169个网络每个网络就代表了该时刻网络的结构状态。1.3 绘制网络(1) 选择从第二个网络开始（其实这是时间网络的初始网络），选择Draw/Network(2) 点击Previous和Next可以动态绘制各时间节点的网络2 .tim文件显示时间网络2.1 读取时间文件l File/Network/Read Time Events-carlyle.tim2.2 生成时间网络 与1.2相同2.3 绘制网络 与1.3相同参考文献：1 官网start with pajek教程 http:/mrvar.fdv.uni-lj.si/sola/info4/andrej/pajek_short.pdf p82-832 官网使用手册 pajekman3 THATCamp Pittsburgh 2013 Networking and the Digital Humanities Workshop. /lombardi/thatcamp/ carlyle.tim（该文件可用） paston.tim(该文件读取时出现内存错误)附录(1) time events网络 Pajekman p9-10Read Time Events Read temporal network described using time events. See Table 1.List of properties s can be empty as well. If several edges (arcs) can connect two vertices, additional tag like :k (k-th line) must be given to determine to which line the command applies. E.g. command HE:3 14 37 results in hiding the third edge connecting vertices 14 and 37.Example of time network described using time events:*Vertices 3*EventsTI 1AV 2 bTE 3HV 2TI 4AV 3 eTI 5AV 1 aTI 6AE 1 3 1TI 7SV 2AE 1 2 1TE 7DE 1 2DV 2TE 8DE 1 3TE 10HV 1TI 12SV 1TE 14DV 1See also other possibility: description of time network using time intervals.(2) time intervals 网络 Pajekman p36-37Temporal Network Operations that are specific to temporal networks. Generate in Time Generate network in specified time(s) or interval.Input first time, last time and step (integers).Additional parameters when vertices and lines are active should be given in network to perform this operation. They must be given between signs and :- is used to divide lower and upper limit of interval, is used to separate intervals,* means infinity. Example:*Vertices 31 a 5-10,12-142 b 1-3,73 e 4-*Edges1 2 1 71 3 1 6-8Vertex a is active from times 5 to 10, and 12 to 14, vertex b in times1 to 3 and in time 7, vertex e from time 4 on. Line from 1 to 2 is active only in time 7, line from 1 to 3 in times 6 to 8.The lines and vertices in a temporal network should satisfy the consistency condition: if a line is active in time t then also its end-verticesare active in time t. When generating time slices of a given temporalnetwork only consistent lines are generated.Note that time records should always be written as last in the row where vertices / lines are defined.See also other possibility of describing time network: description of time network using time events.
