Assignment 2

This assignment is about the features and operations in NodeXL and Gephi.Pleaseperform the tasks below and upload three files to Moodle before 23:59 November 1.

1.Data gathering and network visualization & description with NodeXL

Use the “Twitter Search Network” importer in NodeXL to retrieve tweets about the keyword “港珠澳大桥”, and make sure the scale (number of nodes) of the network is larger than one hundred.

Calculate network metrics (overall graph metrics, in/out degree, betweenness and closeness centralities) and explore the features of the network.

Adjust the visual properties and get a satisfying visualization.

Perform the clustering feature and layout each of the graph’s groups in its own box.

For this task, you need to submit:

A DOC word file – containing the overall summary of the network, description about the opinion leaders (the users who play important roles) of this keyword topic. You should include some network characteristic you learn from class to describe the network and the opinion leaders.

A PNG file – about the network visualization with the layout that each of the graph’s groups in its own box.

2.Network visualization in Gephi

Load the datasets (“Assignment2 data.gephi”) into Gephi

Adjust the visual properties and get a satisfying visualization. (node size, node color, layout)

Visualize the network in the Preview panel and save the graph as PDF file.

For this task, you need to submit:

A PDF file – of the final visualization.

作业2

这个任务是关于NodeXL和Gephi中的功能和操作。请执行下面的任务，并在11月1日23:59之前将三个文件上传到Moodle。

1.使用NodeXL进行数据收集和网络可视化和描述

使用NodeXL中的“Twitter搜索网络”导入程序检索有关关键字“港珠澳大桥”的推文，并确保网络的比例（节点数）大于100。

计算网络指标（总体图表指标，进/出度，中介和亲密度中心）并探索网络的功能。

调整视觉属性并获得令人满意的可视化效果。

执行群集功能并将每个图形组放在其自己的框中。

对于此任务，您需要提交：

DOC文件文件 - 包含网络的总体摘要，关于此关键字主题的意见领袖（扮演重要角色的用户）的描述。您应该包括您从课堂上学到的一些网络特征来描述网络和意见领袖。

一个PNG文件 - 关于网络可视化，其中包含每个图形组在其自己的框中的布局。

2. Gephi中的网络可视化

将数据集（“Assignment2 data.gephi”）加载到Gephi中

调整视觉属性并获得令人满意的可视化效果。 （节点大小，节点颜色，布局）

在“预览”面板中显示网络，并将图形另存为PDF文件。

对于此任务，您需要提交：

PDF文件 - 最终可视化的文件。

Operation instruction for the date import in NodeXL

1. In thefirst task, you will characterize a social network on Twitter using the NodeXL Twitter Import feature. To use this feature, you must first sign up for an account at Twitter.com. You are not required to actually use the Twitter service yourself in order to carry out this research; you only have to sign up for an account

2. Open NodeXL, be sure that you have the NodeXL tab selected on top, and select Import->From Twitter Search Network…

3. The first time you use NodeXL Twitter search, in order to carry out Twitter searches, you must authorize NodeXL by your Twitter account. Select the option that “I have a Twitter account, but I have not yet authorized NodeXL to use my account to import Twitter networks. Take me to Twitter’s authorization page.” After you authorize NodeXL, it will return a verifying number and you should enter it within the NodeXL program.

4. Now, back in the Twitter Search import window, make sure the option “Limit to __ Tweets” is set to 2000. Check the boxes that read “Add a Tweet column…” and “Expand URLs in Tweets.”

5. Enter “港珠澳大桥” (without quotes) in the top-most box. Then click “OK” to start collecting tweets.

You may refer to the “NodeXL in class exercise Instruction” for other operational detail.

NodeXL中日期导入的操作说明

1.在第一项任务中，您将使用NodeXL Twitter导入功能在Twitter上描述社交网络。要使用此功能，您必须先在Twitter.com上注册一个帐户。您不需要自己实际使用Twitter服务来进行此项研究;你只需要注册一个帐户

2.打开NodeXL，确保在顶部选择了NodeXL选项卡，然后选择Import-> From Twitter Search Network ...

3.第一次使用NodeXL Twitter搜索时，为了进行Twitter搜索，您必须通过Twitter帐户授权NodeXL。选择“我有Twitter帐户，但我尚未授权NodeXL使用我的帐户导入Twitter网络”选项。带我到Twitter的授权页面。“在您授权NodeXL之后，它将返回一个验证号码，您应该在NodeXL程序中输入它。

4.现在，返回Twitter搜索导入窗口，确保选项“限制为__推文”设置为2000.选中“添加推文列...”和“扩展推文中的URL”复选框。

5.在最顶部的框中输入“港珠澳大桥”（不含引号）。然后单击“确定”开始收集推文。

您可以参考“课堂练习指令中的NodeXL”了解其他操作细节。
