Reply to comment by ianhillmedia in [OC] How news stories evolve in the news cycle by PartisanPlayground

This is an excellent comment, thank you for this!

I think I need a clearer way of describing "prevalence". This chart is showing the top ten stories by the share of articles written about them, not by the amount that they are consumed. I take articles from 64 sources on every day, cluster them together into "stories", then calculate each story's share based on the number of articles written about it. For example, if there are 1000 articles for a day, and one story has 100 articles written about it, then its share is 10%. Does that make sense?

I've explored measuring consumption of news in the past, and found it to be very difficult! (Facebook's Graph API used to be wide open, so I was able to get likes/engagement on news stories there, but it has since been locked down) Your comment does a great job of explaining the complexity in measuring consumption. You would need to combine:

- GA data from news outlets (which they don't publish)

- Cable news data (sources exist for this, but you would need to make a lot of assumptions to combine this with articles)

- Social media data

And you would need to make a lot of assumptions about what weights to use on each of those. As a result, I'm keeping this simple and focusing on article shares.

I do publish a daily automated Twitter thread on which news outlet gets the most engagement on Twitter. It includes the most liked and ratioed tweets from each "side" of the media. This is limited to Twitter, so does not cover all the channels you described. See an example here: https://twitter.com/PartisanPlayG/status/1619300675094970369

The other thing I've been doing is cutting articles by which "side" of the media they're on using media bias ratings from AllSides. Again, this involves some simplifying assumptions so it's not perfect but gives a good high-level view. You can see examples here: https://partisanplayground.substack.com

Thanks again for your comment. This is exactly the sort of thing I was looking for when I posted.

Happy to help! And I think you’re spot on when you say you need to clarify the definition of prevalence. Just because a news org puts resources into a topic doesn’t mean it’s prevalent to the user. That said, the number of stories a news org efforts on a subject is an interesting data point.

As someone on the other side of this, I hear you on the challenges associated with getting useful data. How are you currently tracking all articles published by those news orgs? And how are you parsing that data to identify specific stories - what search terms are you using to filter the data?

I'm getting the data from the Google News API. I've used RSS feeds in the past with similar results.

And actually I'm using a clustering algorithm to identify the specific stories. I have an automated process that pulls all articles from the past five days, clusters them into stories, then produces a bunch of analysis. This saves me a lot of time and brings some objectivity to the process.

Got it thanks for the reply! I know not everyone supports RSS, and it’s a challenge when folks format RSS in different ways, but as they’re a primary source from the publisher I’d encourage you to use RSS over APIs from Google.

I was curious the signals in your algorithm as well. One of the challenges with automating taxonomies for news stories is the inexactitude of language and differences in style. A story might mention DeSantis and books in the headline and description but might actually be about GOP primaries; a story might emphasize DeSantis in the primaries in the headline and title but it might actually be about book banning.

Or a better example: a story that mentions Tyre Nichols may be about the actual incident, police violence or defunding the police.

Digging in even further, a local news organization might use colloquialisms for place names that can make it difficult for folks from outside that market to categorize those stories.

You're hitting on the most subjective part of this whole process. I've run into all of the issues you describe, and the question is ultimately: how do you define a story?

Your GOP primaries example is a good one. Let's say we have articles on Trump's legal issues, other articles on Pence's classified documents, and other articles on DeSantis and books. Now let's say all of these articles describe these things in the context of the 2024 GOP primaries. Is this one story called "GOP primaries"? Or three separate stories? You could make a case either way.

I've tuned the algorithm to split stories in a way that "looks about right" to me. That's subjective, but there's no way around it. This is an issue whether you're using an algorithm or doing this manually.

A related challenge is that story definitions may change over time. The classified documents story is a good example for this. Right now there are articles on Trump, Biden, and Pence all mishandling classified documents. The algorithm is categorizing all of them as the same story (fair enough).

But let's say that next week (just making this up), Trump gets indicted for it. Is that a separate story now? If so, how do you treat that? Do you retroactively split out the "Trump" portion of the "classified documents" story as though they were not the same story before? Do you show the classified documents story splitting into two? Do you just create a new story on the day the indictment happens? Currently, the algorithm is set up to do the first of these, but again, you could make a case for any of them.

All of this is to say that there is subjectivity involved in this process.
