Dear Analytics Mailing List,
Recently while querying pageviews of various pages, I discovered that the page whose title is a single hyphen character (i.e. with the title "-", with URL https://en.wikipedia.org/wiki/-, which redirects to https://en.wikipedia.org/wiki/Hyphen-minus) receives an unusually high number of pageviews under the Pageview API. Taking October 2015 as an example, the page received 5.4 million pageviews during that month according to the API: < https://wikimedia.org/api/rest_v1/metrics/pageviews/per-article/en.wikipedia...
.
However, according the stats.grok.se (which was still operational in the same month), the page received only 1209 pageviews: http://stats.grok.se/en/201510/-.
Looking at the tabulation of pageviews on Wikipedia Views, the increase in pageviews for this page coincides with the change to the Pageview API in July 2015: < http://wikipediaviews.org/displayviewsformultiplemonths.php?page=-&allmo...
.
As I understand, page titles must be URL-encoded before the query, but the URL-encoding of "-" is itself.
I looked at the API documentation but did not see this behavior listed, so I am wondering where these numbers are coming from.
Best regards, Issa
Hello Issa,
Thank you for your question. The very high number of views of the "-" page is explained by this dash value being used as a special value for "no page title found" when extracting titles from urls. We definitely should document this in the API, creating this task: https://phabricator.wikimedia.org/T150249 Best Joseph

Hi Joseph,
Thanks for the clarification.
Any ideas why this number is much higher for some months? In particular, on desktop, it's high in the months of July to September 2015 (around 10 million, compared to the usual 5 million) and then high again in October 2016 (45 million, about 10x the usual value).
Data is from http://wikipediaviews.org/displayviewsformultiplemonths.php?page=-&allmo... which summarizes results from the Wikimedia API (and stats.grok.se for data before July 2015).

Thank you for linking to that bug, Marcel. Just to verify what you are saying, would it be right to say that the bug fix caused a a lot of pageviews to be moved from the respective (nonexistent) pages to "-" pageviews? And, does that means that the current estimate of "-" pageviews is more accurate than it used to be prior to the bug fix?

fix caused
a a lot of pageviews to be moved from the respective (nonexistent) pages
to "-" pageviews?
No, the bugfix makes those faulty requests to no longer be stored as pageviews thus it cannot make that number increase. I am not sure we can link the surge of "-" pageviews in October to any determined cause without further research. Have filed ticket to that extent, hopefully we can get to it before we do away with raw data: https://phabricator.wikimedia.org/T150990
And, does that means that the current estimate of "-" pageviews is more

Thanks for opening the ticket and for clarifying the issue more.
On a related note, I wonder if you could add the documentation for the unusual amount of pageviews to 404.php as returned by the API. That number also shot up in October 2016; see http://wikipediaviews.org/displayviewsformultiplemonths.php?page=404.php&... for the historical trend.

On a related note, I wonder if you could add the documentation for the
unusual amount of pageviews to 404.php as returned by the API Sorry, we do not know why that is, and gain, it is unrelated to the prior ticket we linked. That ticket changed requests that were (wrongly) returning 200 to (lawfully) return 404. Please take a closer look, it is not about the api. Requests that return 404 are not consider pageviews and thus will not appear on pageview API.
Api calls to 404.php are an entirely different matter, knowing little about the api we have no idea what those represent.

Thanks for opening the ticket and for clarifying the issue more.

That number also shot up in October 2016; see http://wikipediaviews.org/ displayviewsformultiplemonths.php?page=404.php&allmonths= allmonths&drilldown=all for the historical trend.

No, the bugfix makes those faulty requests to no longer be stored as pageviews thus it cannot make that number increase. I am not sure we can link the surge of "-" pageviews in October to any determined cause without further research. Have filed ticket to that extent, hopefully we can get to it before we do away with raw data: https://phabricator.wiki media.org/T150990
And, does that means that the current estimate of "-" pageviews is more
accurate than it used to be prior to the bug fix? No, it doesn't.

Maybe the high value in October (45M) has something to do with the last changes in https://phabricator.wikimedia.org/T145922 ?

Hi Joseph,
Thanks for the clarification.
Any ideas why this number is much higher for some months? In particular, on desktop, it's high in the months of July to September 2015 (around 10 million, compared to the usual 5 million) and then high again in October 2016 (45 million, about 10x the usual value).
Data is from http://wikipediaviews.org/displayviewsformultiplemonths .php?page=-&allmonths=allmonths&drilldown=all which summarizes results from the Wikimedia API (and stats.grok.se for data before July 2015).

Thanks for the documentation. Does this only affect data provided by the API, or also the page_title field in the pageview_hourly table, i.e. the source of the API data?
In the latter case, please also add a note to the "known problems" at https://wikitech.wikimedia.org/wiki/Analytics/Data/Pageview_hourly . (This is the canonical place for documenting such issues - thanks for making this explicit at https://wikitech.wikimedia.org/wiki/Analytics/PageviewAPI#Issues_with_data . Separately, for pageview definition changes there is also https://meta.wikimedia.org/wiki/Research:Page_view#Change_log . No objections of course if the Analytics team commits to keeping the information up to date in all three places.)
Also, just out of curiosity and to better understand the issue, what would be an example of a real life request URL that results in such a "no page title found" error when extracting the title?

Dear Analytics Mailing List,
Recently while querying pageviews of various pages, I discovered that the page whose title is a single hyphen character (i.e. with the title "-", with URL https://en.wikipedia.org/wiki/-, which redirects to https://en.wikipedia.org/wiki/Hyphen-minus) receives an unusually high number of pageviews under the Pageview API. Taking October 2015 as an example, the page received 5.4 million pageviews during that month according to the API:
However, according the stats.grok.se (which was still operational in the same month), the page received only 1209 pageviews: http://stats.grok.se/en/201510/-.
Looking at the tabulation of pageviews on Wikipedia Views, the increase in pageviews for this page coincides with the change to the Pageview API in July 2015:
http://wikipediaviews.org/displayviewsformultiplemonths.php?page=-&allmonths=allmonths&drilldown=all.
As I understand, page titles must be URL-encoded before the query, but the URL-encoding of "-" is itself.
I looked at the API documentation but did not see this behavior listed, so I am wondering where these numbers are coming from.

Also, just out of curiosity and to better understand the issue, what would be an example of a real life request URL that results in such a "no page title found" error when extracting the title?
Special page requests, for example.
Normally pages like "Special:Blah" are "actions" not pages themselves. We do not count those as pageviews with the notably exception of Search requests (as they do provide content). So a page like "Special:Search: Blah-Blah" would be an example of a pageview with title "-" on pageview_hourly table.
