NodeXL has new updates to its importers for Twitter users and lists.
We have released an updated version of NodeXL that simplifies and merges the previously separate User and List importers.
The new, streamlined importer treats an individual user as a list of one.
Lists can be defined by pointing to an existing Twitter List or simply entering a list of delimited user names into the text box.
The updated importer now collects many more tweets per person and parses these messages to generate reply and mention edges.
You can now define a group of Twitter users and find out how much they reply and mention one another.
You can even pull in the followers of each person, to see if they reply or mention people they also follow.
But ever since June 11, 2013, Twitter has made access to the “follows” edge data very difficult (its just very slow). Designed and implemented prior to the update that restricted access to the follower network, the original NodeXL Twitter list importers relied mostly on queries that are now impractically slow for all but the smallest lists of users who have small collections of followers.
The update to these User and List importer is partially an adaptation to these changes. The importer shifts away from the follower network to focus on the communication interaction data in the content of Tweets. Since Twitter offers more generous access to Tweets than to information about who follows who, we are obliged to make better use of what they do offer.
The results are insightful! Here is a map of the connections among the members of the United States Congress.
The NodeXL team from the Social Media Research Foundation has released a web application that allows users to upload network files and download files other users have uploaded.
The Social Media Research Foundation is dedicated to Open Tools, Open Data, and Open Scholarship.
The NodeXL Graph Gallery on the Web enables the research community to collectively gather and share data sets.
Users of NodeXL will notice a new NodeXL>Data>Export>To Web Gallery menu option which opens this dialog box:
Users will be able to browse the NodeXL Web Gallery for graphs that were recently uploaded:
Users will be able to search for graphs that contain certain keywords:
Users can then get details about the network graph and download those files they would like to investigate.
Lists are a recent feature of Twitter which enable users to compile collections of users to follow in a single tweet stream. People can add up to 500 people to follow on a single list. People on a list may be connected to one another if one follows the other.
Some people on a list may have many connections. Some have only a few or even no connections to others on the list.
In version 161 of NodeXL you may now create maps of the connections among a list of Twitter users.
There are two options in this feature. One makes use of the List functions in Twitter. If you request the map for a single twitter list, NodeXL will build a map of the connections among all the people Twitter reports as being on the list. You can create and manage the people on a list using the Twitter list features, or select an existing Twitter list created by other users.
A second option in this feature accepts a list of up to 10,000 twitter user names pasted into the query text box. If you have a list of users and want a map of how they are connected, and the list is not already in Twitter, just paste them here and get a map.
Either way, a connection will be created for every two users if one follows the other.
