"404 not found": An update for "bioinformatics/cabios"
Yesterday, I blogged about the persistence of the URLs present in the abstract of NAR. Today , I've updated my tool and used it to scan the abstracts of the following pubmed query: "Bioinformatics"[JOUR] or "Comput Appl Biosci"[JOUR].
Here is the result:
Year | Total | Alive | % |
---|---|---|---|
18 | 1 | 5 | |
1995 | 1 | 0 | 0 |
1996 | 9 | 3 | 33 |
1997 | 13 | 3 | 23 |
1998 | 86 | 19 | 22 |
1999 | 70 | 17 | 24 |
2000 | 83 | 25 | 30 |
2001 | 110 | 64 | 58 |
2002 | 121 | 78 | 64 |
2003 | 284 | 170 | 59 |
2004 | 402 | 257 | 63 |
2005 | 495 | 359 | 72 |
2006 | 374 | 297 | 79 |
2007 | 448 | 381 | 85 |
2008 | 466 | 415 | 89 |
2009 | 507 | 462 | 91 |
2010 | 605 | 566 | 93 |
2011 | 283 | 268 | 94 |
Again, even if we can reach a web site, it doesn't mean that the service described in an article is still available or maintained.
As suggested by Egon Willighagen, I've uploaded the RDF output of my program on figshare: http://figshare.com/figures/index.php/Bioinformatics.404_20110415.rdf.
That's it,
Pierre

Could you correlate the probability of a resource giving a 404 with citation count?
Pierre, please check the figure on FigShare... it gives a Zoho 404. Oh, the irony :)
Nice work, Pierre, it looks like the Chief Executive of the BBSRC is paying attention to the analysis on your blog: http://blogs.bbsrc.ac.uk/index.php/2011/04/biofuels-bioenergy-neuroscience/
I wonder how many of the URLs are recoverable from the Internet Archive or Momento though.
We don't assume that because a journal no longer exists, the papers are not in the library any more. We seem to be making this mistake here.
I think we could need a virtual service landscape simply ensuring that services in their state are being hold on that level, even if all technology around them is moving on.
Food for thought ...
