We often talk about the new news ecosystem — the network of traditional outlets, new startups, nonprofits, and individuals who are creating and filtering the news. But how is the work of reporting divvied up among the members of that ecosystem?

To try to build a datapoint on that question, I chose a single big story and read every single version listed on Google News to see who was doing the work. Out of the 121 distinct versions of last week’s story about tracing Google’s recent attackers to two schools in China, 13 (11 percent) included at least some original reporting. And just seven organizations (six percent) really got the full story independently.

But as usual, things are a little more subtle than that. I chose the Google-China story because it’s complex, international, sensitive, and important. It’s the sort of big story that requires substantial investigative effort, perhaps including inside sources and foreign-language reporting. Call it a stress test for our reporting infrastructure, a real-life worst case.

The New York Times broke the story last Thursday, writing that unnamed sources involved in the investigation of last year’s hacking of a number of American companies had traced the attacks to a prestigious technical university and a vocational college in mainland China. The article included comment from representatives of the schools and, while it had a San Francisco dateline, credited contributions from Shanghai staff. Immediately, the story was everywhere. Just about every major American newspaper and all the wires covered it.

When I started investigating the issue on Monday morning, Google News showed 800 different reports. But how many of these reports actually brought new information to light? By default, Google does not display duplicate copies of syndicated (or stolen) content, bringing the total down to more than 100 unique pieces of copy. I read each one, and several hours later, I had a spreadsheet recording the sourcing for each story. I also recorded the country of publication, the dateline or contributor location if noted, and the primary publishing medium of each outlet (paper, online, radio, etc.) An excerpt of this data is reproduced in the table below.

Here’s what I found:

— Out of 121 unique stories, 13 (11 percent) contained some amount of original reporting. I counted a story as containing original reporting if it included at least an original quote. From there, things get fuzzy. Several reports, especially the more technical ones, also brought in information from obscure blogs. In some sense they didn’t publish anything new, but I can’t help feeling that these outlets were doing something worthwhile even so. Meanwhile, many newsrooms diligently called up the Chinese schools to hear exactly the same denial, which may not be adding much value.

— Only seven stories (six percent) were primarily based on original reporting. These were produced by The New York Times, The Washington Post, the Wall Street Journal, The Guardian, Tech News World, Bloomberg, Xinhua (China), and the Global Times (China).

— Of the 13 stories with original reporting, eight were produced by outlets that primarily publish on paper, four were produced by wire services, and one was produced by a primarily online outlet. For this story, the news really does come from newspapers.

— 14 reports (12 percent) were produced by Chinese outlets, had a China dateline, or mentioned the assistance of staff in China. For a story about China, that seems awfully low to me. Perhaps this has to do with cutbacks of foreign correspondents?

— Nine reports (7 percent) mentioned no source at all. Five more were partially unsourced. Given the ease of hyperlinks, this frightens me.

— Google News tended to rank solid original stories fairly high in its list. Google says they rank stories based on criteria such as the reputation of a source, number of references by other articles, and the headline clickthrough rate — though they won’t reveal exactly how it’s done. The spreadsheet and table below list stories in the order that Google News ranked them.

— Google’s story-clustering algorithm included three unrelated stories and missed at least one original report. The three extraneous stories were about Google and China, but not about the recent trace. The exclusion of the Financial Times’ excellent piece is a disappointment — perhaps this has something to do with their paywall? Maybe I’m biased because, as a computer scientist, I appreciate the difficulty of the problem — but I actually think this means that Google News works remarkably well, for a completely unsupervised algorithm that crawls billions of pages to find millions of stories in dozens of languages.

— What were those other 100 reporters doing? When I think of how much human effort when into re-writing those hundred other unique stories that contained no original reporting, I cringe. That’s a huge amount of journalistic effort that could have gone into reporting other deserving stories. Why are we doing this? What are the legal, technical, economic and cultural barriers to simply linking to the best version of each story and moving on?

— The punchline is that no English-language outlet picked up the original reporting of Chinese-language Qilu Evening News, which was even helpfully translated by Hong Kong blogger Roland Soong. A Chinese reporter visited one of the schools in question and advanced the story by clarifying that serious hackers were unlikely to have been trained in the vocational computer classes offered there. Soong told me that Lanxiang Vocational School is well known in China for their cheesy late-night commercials and low-quality schooling — more of an educational chop shop for cooks and mechanics than the training ground for military hackers than the Times claims.

Tracing one story doesn’t prove anything conclusive beyond that one story, of course. And using Google News as a filter doesn’t truly represent the new news ecosystem: It excludes lots of smaller blogs and other outlets. Soong said Google News told him that his site is not eligible for inclusion in their results because they don’t include small blogs written by a single author. This seems like an arbitrary distinction, but it’s hard to imagine what defensible choice Google could make in an era where the definition of a news source is so up for grabs.

The table below is an extract from the data I collected, with original reporting highlighted. The full spreadsheet also includes country of publication, primary medium for each organization, and lists whether or not each story hyperlinked to its sources.
