Some rudimentary data science from the WikiRank project:
We can draw a map of UN member states and their log10 PageRank centrality:
<-4.5
-4.3 to -4.5
-4 to -4.3
-3.7 to -4
-3.3 to -3.7
-2.836 to -3.3
Notice, though, that it appears to correlate with overall economic size. Plotting GDP (nominal) against -log10 PageRank centrality:
It makes sense, then, to adjust for the size of the country's economy using the logarithmic interpolation, using the formula:
This gives the adjusted map:
1.05-1.142
1.025-1.05
1 to 1.025
-0.965 to 1
0.93 to 0.965
<0.93
The ten highest states are:
| Rank | Country | Ratio |
|---|---|---|
| 1 | Iran | 0.8324533513 |
| 2 | Romania | 0.9065791461 |
| 3 | France | 0.9080441941 |
| 4 | Nepal | 0.9102667925 |
| 5 | Somalia | 0.9139302456 |
| 6 | Estonia | 0.9162380653 |
| 7 | Madagascar | 0.9234474791 |
| 8 | India | 0.9282444325 |
| 9 | New Zealand | 0.9299828459 |
| 10 | Sri Lanka | 0.9314158037 |
We may also look at individual projects, using the data of the WP 1.0 bot and article quality/importance rankings. Here are three graphs from WikiProject Mathematics (captions are self-explanatory):
We can apply a similar technique to adjusting the PageRank vs quality data as we did to the countries' data, to produce a sort of 'neglect ratio', i.e. to identify those articles with much lower quality, as ranked 1 (Stub) to 8 (FA), than would be expected given their centrality. The 100 articles thus in most need of our attention are:
