Repeated column meaning in database crawled from Twitter?

r

#1

Twitter Data is crawled and nested upto 6th level. Many columns are repeated at root level or within the nested level. The link is given as below for reference,

Data Link

I can not understand the meaning of few of the columns. If possible explain by taking the reference from root level because the columns inside the deep level are repeated.

Generally we understand the meaning of data columns, but when it is repeated in different context in same database (from different root level) then it is cumbersome to understand the meaning. Hope I will get the proper answer.

Example of 1st record is mentioned as below,

Schema is reproducible in R. If anyone want I can provide R code to see the details.

Do you have any documentation on this you can point to?

Beyond documentation, one good way to understand the meaning of a variable is to look at a few examples and consider the context of where the data originated. As an absurdly simple example of a var marked by asterisks, I suspect *created_at* is a string noting the date and time this record was created at.


Looks like you also cross-posted here:

From: FAQ: Is it OK if I cross-post?

  • First, avoid cross-posting to other websites.
  • If you must, always link to those other posts, and update with any solutions.

Why? - Not doing so is generally considered to be rude - someone might spend their time answering the question on StackOverflow, for example, when it’s already been answered here. And once you have an answer in one place, it's polite to update all of your questions accordingly.


#3

Please see the database again. Many columns are repeated. So If possible I expect overall columns' meaning description in short and neat way. Repeated columns increases confusion.

The difference in this question from stackoverflow is -- one record from database is provided, anyone can reproduce the example.
