Node XL API?

Mar 13, 2012 at 2:59 PM

I am working with nodeXL to retrieve Tweets for research. I read on the book that it uses REST API from Twitter. 

Nevertheless, many things have changed since the publication. Are you still using REST? I am searching hashtags or popular terms, what is the sampling process?

Also, I see the time of the tweets is the same in all, the time shown in the excel sheet is the time all the tweets are put in excel or actually the real time the tweet was published.

Thank you.

NodeXL's Twitter Search Network uses Twitter's "Search API."  Specifically, it calls the following URL:

http://search.twitter.com/search.atom

You can find the documentation for this at https://dev.twitter.com/docs/api/1/get/search.

The Twitter Search API returns up to 1,500 tweets that satisfy your query.  NodeXL identifies the unique authors among the returned tweets and creates a vertex for each such author.  It then creates edges between the authors based on what you check under "Add an edge for each..." in the Import from Twitter Search Network dialog box.

The "Relationship Date (UTC)" column on the Edges worksheet is set to the time of the tweet in rows for which the "Relationship" column is "Replies-to," "Mentions," or "Tweet."  In other words, if the row represents a tweet, you get the tweet time.  It is set to the time you ran the query when Relationship is "Followed," where the row represents a follows relationship.

Hi Tony,

This information was VERY helpful.

I would like to cite some of it, could you describe me your position in the organization? 

THANK YOU!

Thanks for offering the citation, Leonor.  Below my signature are some notes I found at http://nodexl.codeplex.com/documentation regarding citations.  If you would like to narrow it down, you can just say "NodeXL programming team."
