The data are from Yassine Gargouri (who has used the methodology he previously used, which consists of trawling the web for openly accessible full-texts and comparing the number of those with the papers in Web of Science, which is not a perfect, but a reasonable measure of the ‘universe’ for UK researchers).<br>
</span></font></div></blockquote><div><br>Is this published anywhere (formally or informally) such that we can understand the details? <br>* How does he or Google know that the full-text is "openly accessible"? Is this by trying to read it or is there a Google flag for openly accessible?<br>

<br>
Previously, Yassine has done this only on a global basis, but this time he has looked for papers with at least one UK author.<br>
<br></span></font></div></blockquote><div>* How is this done? Does *he* analyze the author affiliations or does he get them from WoS?<br> <br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">

* How was the subject classification done?<br><br>I can see one method how the "Gold" access papers were retrieved - by mapping the Journal onto known Gold journals (sic). (I cannot see how hybrid gold were easily measured but the numbers are probably too small to worry about statistically)<br>
<br>I cannot see the next phase but I can conjecture. More questions:<br>* did he use his/Google results to compare with WoS?<br><br>* how did he determine that the paper was Green? Almost by definition this has to be somewhere other than the publisher's site. [so the paper needs another search for the paper mounted somewhere OTHER than the publisher. <br>
<br>* does he then have a system to determine whether the paper is readable (not all papers in repositories are readable, as we have seen).<br><br>If he has such as system then it would seem to answer the key question:<br>
* if I find a paper on a publisher's site can I find a free-as-in-beer copy somewhere else on the web?<br><br>If he can really answer that question then is his system openly available?<br><br>P.<br><br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">
