Using Webometrics to Rank University Systems

Recently there has been some interest in ranking higher education systems in addition to institutions or departments. See here and here.  But both of these efforts, from Universitas 21 and QS, rank only 50 countries.

The Webometrics rankings attempt to cover every university in the world or anything that might conceivably claim to be a university, institute or college. The indicators comprise web activity and research output. So, there is data here to create a simple and comprehensive  ranking of countries. Below is the list of countries and territories ranked according to the world rank of the highest ranked university. If the Webometrics methodology remains unchanged it will be updated twice a year.

The table is not very surprising overall but it is worth noting that the leading Asian countries are already in the top ten and that Brazil and Mexico  are not too far behind. The performance of Arab countries is not too impressive even if they are rich in oil.

It's a safe bet that the highest ranked Chinese university will rise steadily over the next few years followed by South Korea and Singapore, but probably not Hong Kong and Australia.

Rankings case shows need to reform citations indicator

My previous post has just been republished by University World News.

Comments here are welcome.

Trinity College Dublin: Time to forget about THE?:

Global rankings, especially THE's, have been very useful to British universities, at least to those sitting at the apex of the system. If a Russell Group university falls in the rankings then it is the fault of impending Brexit and/or the terrible austerity inflicted on the nation's research prowess. If it rises then this is cause for congratulation but with a hint of foreboding. How can they keep advancing with Ebenezer Scrooge controlling  the treasury and the bitter winds of Brexit howling at the door? The universities have reciprocated by not inquiring about how THE constructs its rankings, particularly the citations and industry income indicators. 

Across the Irish Sea, universities have for the most part also been loyal to THE. Trinity College Dublin (TCD) has continued to submit data to THE and also to QS and has passively accepted the results of the rankings even when they show the institution going down and down. The steady decline is usually blamed on the meanness of the Irish government and its failure to provide sufficient funds.

I have dealt with Trinity's misfortunes here,  here, here, and here, In 2015 TCD fell seven places in the QS world rankings and 22 in THE's. In contrast it had been rising in the Shanghai ARWU rankings since 2004 and in the Round University Rankings (RUR) since 2010, although everybody pretended not to notice this.

This year history repeats itself all over again. TCD has fallen in THE world rankings from 120th place to 164th. Again this supposedly is the fault of the Irish state to provide enough money.

But we get a very different picture when we look at the Shanghai Rankings. TCD has risen from 167th place to 154th, getting close to the 101-150 band. Leaving aside the Nobel and Fields Awards, Trinity has gained 6.6 points for highly cited researchers, 1.4 for publications, and 1.4 for productivity per capita. It has, however, fallen 0.6 for papers in Nature and Science.

Looking at RUR, TCD has risen from 75th to 57th for Research and 35th to 29th for international diversity. It has fallen slightly for financial sustainability from 191st to 197th and for Teaching from 275th to 335th, mainly because of a fall in the number of academic staff.

It seems perverse for TCD to keep on about its decline in the THE rankings when it can point to a steady rise in the Shanghai rankings which are not perfect but are certainly more stable, consistent and realistic than THE. 

Does THE really want to be judged by rankings that apparently think that Anadolu University is best for Innovation, Luxembourg for International Orientation and Aswan for research impact measured by Citations?

But if TCD really insist on sticking with THE then I suggest that they recruit a few researchers taking part in the Global Burden of Disease Study, funded by the Bill and Melinda Gates Foundation.*

They should also think about amalgamating with the Royal College of Surgeons.

Seven Modest Suggestions for Times Higher Education

My post of the 24th of August has been republished in Arabia Higher Education

Going Up and Up Down Under: the Case of the University of Canberra

It is a fact almost universally ignored that when a university suddenly rises or falls many places in the global rankings the cause is not transformative leadership, inclusive excellence, team work, or strategic planning but nearly always a defect or a change in the rankers' methodology.

Let's take a look at the fortunes of the University of Canberra (UC) which THE world rankings now have in the world's top 200 universities and Australia's top ten. This is a remarkable achievement since the university did not appear in these rankings until 2015-16 when it was placed in the 500-600 band with very modest scores of 18.4 for teaching, 19.3 for research, 29.8 for citations, which is supposed to measure research impact, 36.2 for industry income, and 54.6 for international outlook.

Just four years later the indicator scores are 25.2 for teaching, 31.1 for research, 99.2 for citations, 38.6 for industry income, and 86.9 for international orientation. 

The increase in the overall score over four years, calculated with different weightings for the indicators, was composed of 20.8 points for citations and 6.3 for the other four indicators combined. Without those 20.8 points Canberra would be in the 601-800 band.

I will look at where that massive citation score came from in a moment. 

It seems that the Australian media is reporting on this superficially impressive performance with little or no scepticism and without noting how different it is from the other global rankings. 

The university has issued a statement quoting vice-chancellor Professor Deep Saini as saying that the "result confirms the steady strengthening of the quality at the University of Canberra, thanks to the outstanding work of our research, teaching and professional staff" and that the "increase in citation impact is indicative of the quality of research undertaken at the university, coupled with a rapid growth in influence and reach, and has positioned the university as amongst the best in the world."

The Canberra Times reports that the vice-chancellor has said  that part of the improvement was the result of a talent acquisition campaign while noting that many faculty were complaining about pressure and excessive workloads.

Leigh Sullivan, DVC for research and innovation, has a piece in the Campus Morning Mail that hints at reservations about UC's apparent success, which is " a direct result of its Research Foundation Plan (2013-2017) and "a strong emphasis on providing strategic support for research excellence in a few select research areas where UC has strong capability." He notes that when the citation scores of research stars are excluded there has still been a significant increase in citations and warns that what goes up can go down and that performance can be affected by changes in the ranking methodology.

The website riotact quotes the vice-chancellor on the improvement in research quality as evidence by the citation score and as calling for more funding for universities: the "government has to really think and look hard at how well we support our universities. That's not to say it badly supports us, it's that the university sector deserves to be on the radar of our government as a major national asset."

The impressive ascent of UC is unique to THE. No serious ranking puts it in the top 200 or anywhere near. In the current Shanghai Rankings it is in the 601-700 band and has been falling for the last two years. In Webometrics it is 730th in the world and 947th for Excellence, that is publications in the 10% most cited in 25 disciplines.  In  University Ranking by Academic Performance it is 899th and in the CWUR Rankings it doesn't even make the top 1,000.

Round University Ranking and Leiden Ranking do not rank UC at all.

Apart from THE UC does best in the QS rankings where it is 484th in the world and 26th in Australia.

So how could UC perform so brilliantly in THE rankings when nobody else has recognised that brilliance? What does THE know that nobody else does? Actually, it does not perform brilliantly in the THE rankings, just in the citations indicator which is supposed to measure research influence or research impact.

This year UC has a score of 99.2 which puts it in the top twenty for citations just behind Nova Southeastern University in Florida and Cankaya University in Turkey and ahead of Harvard, Princeton and Oxford. The top university this year is Aswan University in Egypt replacing Babol Noshirvani University of Technology in Iran. 

No, THE is not copying the interesting methodology of the Fortunate 500. This is the result of an absurd methodology that THE is unable or unwilling for some reason to change.

THE has a self-inflicted  problem with  a small number of papers that have hundreds or thousands of "authors" and collect thousands of citations. Some of these are from the CERN project and THE has dealt with them  by using a modified form of fractional counting for papers with more than a thousand authors. That has removed the privilege of institutions that contribut to CERN projects but has replaced it with the privilege of those that contribute to the Global Burden of Disease Study (GBDS) whose papers tend to have hundreds but not thousands of contributors and sometimes receive over a thousand citations. As a result, places like Tokyo Metropolitan University, National Research University MEPhI and Royal Holloway London have been replaced as citation super stars by St Georges' London, Brighton and Sussex Medical School, and Oregon Health and Science University.

It would be a simple matter to apply fractional counting to all papers, dividing the number of citations by the number of authors. After all Leiden Ranking and Nature Index manage to do it but THE for some reason has chosen not to follow.

The problem is compounded by counting self-citations, by hyper-normalisation so that the chances of hitting the jackpot with an unusually highly cited paper are increased, and by the country bonus that boosts the scores for universities by virtue of their location in low scoring countries. 

And so to UC's apparent success this year. This is entirely the result of it's citation score which is entirely dependent on THE's methodology. 

Between 2014 and 2018 UC had 3,825 articles in the Scopus database of which 27 were linked to the GBDS which is funded by the Bill and Melinda Gates Foundation. Those 27 articles, each with hundreds of contributors, have received 18,431 citations all of which are credited to UC and its contributor. The total number of citations is 53,929 so those 27 articles accounted for over a third of UC's citations. Their impact might be even greater if they were cited disproportionately soon after publication.

UC has of course improved its citation performance even without those articles but it is clear that they have made an outsize contribution. UC is not alone here. Many universities in the top 100 for citations in the THE world rankings owe their status to the GBDS: Anglia Ruskin, Reykjavik, Aswan, Indian Institute of Technology Ropar, the University of Peradeniya, Desarrollo, Pontifical Javeriana and so on.

There is absolutely nothing wrong with the GBDS nor with UC encouraging researchers to take part. The problem lies with THE and its reluctance to repair an indicator that produces serious distortions and is an embarrassment to those universities who apparently look to the THE rankings to validate their status.

What should universities do about organised cheating?

Every so often the world of higher education is swept by a big panic about systemic and widespread cheating. The latest instance is concern about contract cheating or essay mills that provide bespoke essays or papers for students.

It seems that the Australian government will introduce legislation to penalise the supply or advertising of cheating services to students. There are already laws in several American states and there have been calls for the UK to follow suit.

There is perhaps a bit of hypocrisy here. If universities in Europe Australia and North America admit more and more students who lack the cognitive or language skills to do the required work and if they chose to use assessment methods that are vulnerable to deception and dishonesty such as unsupervised essays and group projects then cheating is close to inevitable. 

On the supply side there appear to be large numbers of people around the world without decent academic jobs or jobs of any sort who are capable of producing academic of a high standard, sometimes worth an A grade or a first. The Internet has made it possible for lazy or incompetent students to link up with competent writers.

The Daily Mail has reported that Kenya hosts a medium sized industry with  students and academics slaving away to churn out essays for British and American students. This is no doubt a hugely exploitative business but consider the consequences of shutting down the essay mills. Many educated Kenyans are going to suffer financially. Many students will drop out, resort to  other forms of cheating, or will demand more support and counselling and transitional or foundation programmes.

If universities are serious about the scourge of essay mills they need to work on both the supply and the demand side. They might start by offering the essay writers in Kenya to apply scholarships for undergraduate or postgraduate courses or posts in EAP departments. 

On the demand side the solution seems to be simple. Stop admitting students because they show leadership ability, have overcome adversity, will make the department look like Britain, America or the world, will help craft an interesting class, and admit them because they have demonstrated an ability to do the necessary work.

Are UK universities facing a terrible catastrophe?

A repeated theme of mainstream media reporting on university rankings (nearly always QS or THE) is that Brexit has inflicted, is inflicting, or is surely going to inflict great damage on British education and the universities because they will not get any research grants from the European Union or be able to network with their continental peers.

The latest of these dire warnings can be found in a recent edition of the Guardian, which is the voice of the British progressive  establishment. Marja Makarow claims that Swiss science was forced "into exile" after the 2014 referendum on immigration controls. Following this, Switzerland supposedly entered a period of isolation without access to Horizon 2020 or grants from the European Research Council and with a declining reputation and a loss of international collaboration and networks. This will happen to British research and universities if Brexit is allowed to happen.

But has Swiss research suffered? A quick tour of some relevant rankings suggests that it has not. The European Research Ranking which measures research funding and networking in Europe has two Swiss universities in the top ten. The Universitas 21 systems rankings put Switzerland in third place for output, up from sixth in 2013, and first for connectivity.

The Leiden Ranking shows that EPF Lausanne and ETH Zurich have fallen for total publications between 2011-14 and 2014-17 but both have risen for publications in the top 10% of journals, a measure of research quality.

The Round University Rankings show that EPF and ETH have both improved for research since 2013 and both have improved their world research reputation.

So it looks as though Switzerland has not really suffered very much, if at all. Perhaps Brexit, if it ever happens, will turn out to be something less than the cataclysm that is feared, or hoped for.

Finer and finer rankings prove anything you want

If you take a single metric from a single ranking and do a bit of slicing by country, region, subject, field and/or age there is a good chance that you can prove almost anything, for example that the University of the Philippines is a world beater for medical research. Here is another example from the Financial Times.

An article by John O'Hagan, Emeritus Professor at Trinity College Dublin, claims that German universities are doing well for research impact in the QS economics world rankings. Supposedly, "no German university appears in the top 50 economics departments in the world using the overall QS rankings. However, when just research impact is used, the picture changes dramatically, with three German universities, Bonn, Mannheim and Munich, in the top 50, all above Cambridge and Oxford on this ranking."

This is a response to Frederick Studemann's claim that German universities are about to move up the rankings. O'Hagan is saying that is already happening.

I am not sure what this is about. I had a look at the most recent QS economics rankings and found that in fact Mannheim is in the top fifty overall for that subject. The QS subject rankings do not have a research impact indicator. They have academic reputation, citations per paper, and h-index, which might be considered proxies for research impact, but for none of these are the three universities in the top fifty. Two of the three universities are in the top fifty for academic research reputation, one for citations per paper and two for h-index.

So it seems that the article isn't referring to the QS economics subject ranking. Maybe it is the overall ranking that professor O'Hagan is thinking of? There are no German universities in the overall top fifty there but there are also none in the citations per faculty indicator. 

I will assume that the article is based on an actual ranking somewhere, maybe an earlier edition of the QS subject rankings or the THE world rankings or from one of the many spin-offs. 

But it seems a stretch to talk about German universities moving up the rankings just because they did well in one metric in one of the 40 plus international rankings in one year.

Seven modest suggestions for Times Higher

The latest fabulous dynamic exciting trusted prestigious sophisticated etc etc Times Higher Education (THE) world academic summit is coming. 

The most interesting, or at least the most amusing, event will probably be the revelation of the citations indicator which supposedly measures research impact. Over the last few years this metric has discovered a series of unexpected world-class research universities: Alexandria University, Tokyo Metropolitan University, Anglia Ruskin University, the University of Reykjavik, St. George's London, Babol Noshirvani University of Technology, Brighton and Sussex Medical School. THE once called this their flagship indicator but oddly enough they don't seem to have got round to releasing it as a standalone ranking.

But looking at the big picture, THE doesn't appear to have suffered much, if at all, from the absurdity of the indicator. The great and the good of the academic world continue to swarm to THE summits where they bask in the glow of the charts and tables that confirm their superiority.

THE have hinted that this summit will see big reforms to the rankings especially the citations indicator. That would certainly improve their credibility although they may be less interesting.

I have discussed THE's citation problems here, here, here, and here. So, for one last time, I hope, here the main flaws and we will see whether THE will fix them.

1. A 30% weighting for any single indicator is far too high. It would be much better to reduce it to 10 or 20%.

2. Using only one method to measure citations is not a good idea. Take at look at the Leiden Ranking and play around with the settings and parameters. You will see that you can get very different results with just a bit of tweaking. It is necessary to use a variety of metrics to get a broad picture of research quality, impact and influence.

3. THE have a regional modification or country bonus that divides the research impact score of universities by the square root of the scores of the country where they are located. The effect of this is to increase the score of every university except those in the top ranking country with the increase being greater for those with worse research records. This applies to half of the indicator and is supposed to compensate for some researchers lacking access to international networks. For some reason this was never a problem for the publications, income or international indicators. Removing the bonus would do a let to make the metric more credible.


4. The indicator is over-normalized. Impact scores are bench marked to the world average for over three hundred fields plus year of publication. The more fields the greater the chance that a university can benefit from an anomalous paper that receives an unusually high number of citations. It would help if THE reduced the number of fields although that seems unlikely.

5. Unless a paper has over a thousand authors THE treat every single contributor as receiving every single citation. Above that number they use fractional counting. The result is that the THE rankings privilege medical institutions such as St George's and the Brighton and Sussex Medical School that take part in multi-author projects such as the Global Burden of Disease study. All round fractional counting would seem the obvious answer although it might add a bit to costs.

6. Self-citation has become an issue recently. THE have said several times that it doesn't make very much difference. That may  be true but there have been occasions when a single serial self citer can make a university like Alexandria or Veltech soar into the research stratosphere and that could happen again.

7.  A lot of researchers are adding additional affiliations to their names when they publish. Those secondary, tertiary, sometimes more affiliations are counted by rankers as though they were primary affiliations. It would make sense to count only primary affiliations as ARWU does with highly cite researchers.

Rankings are everywhere

This is from an Indian website. The QS World University Rankings are being used to sell real estate in Australia.

SYDNEY: Leading Australian developer Crown Group is developing six new residential apartment developments near six of the world's top 200 university cities, according to the new QS World University Rankings 2020.

University of the Philippines beats Oxford, Cambridge, Yale, Harvard, Tsinghua, Peking etc etc

Rankings can do some good sometimes. They can also do a lot of harm and that harm is multiplied when they are sliced more and more thinly to produce rankings by age, by size, by mission, by region, by indicator, by subject. When this happens minor defects in the overall rankings are amplified.

That would not be so bad if universities, political leaders and the media were to treat the tables and the graphs with a healthy scepticism. Unfortunately, they treat the rankings, especially THE, with obsequious deference as long as they are provided with occasional bits of publicity fodder.

Recently, the Philippines media have proclaimed that the University of the Philippines (UP) has beaten Harvard, Oxford and Stanford for health research citations. It was seventh in the THE Clinical, Pre-clinical and Health category behind Tokyo Metropolitan University, Auckland University of Technology, Metropolitan  Autonomous University Mexico, Jordan University of Science and Technology, University of Canberra and Anglia Ruskin University.

The Inquirer is very helpful and provides an explanation from the Philippine Council for Health Research and Development that citation scores “indicate the number of times a research has been cited in other research outputs” and that the score "serves as an indicator of the impact or influence of a research project which other researchers use as reference from which they can build on succeeding breakthroughs or innovations.” 

Fair enough, but how can UP, which has a miserable score of  13.4 for research in the same subject ranking have such a massive research influence? How can it have an extremely low output of papers, a poor reputation for research, and very little funding and still be a world beater for research impact.

It is in fact nothing to do with UP, nothing to do with everyone working as a team, decisive leadership or recruiting international talent.

It is the result of a bizarre and ludicrous methodology.  First, THE does not use fractional counting for papers with less than a thousand authors. UP, along with many other universities, has taken part in the Global Burden of Disease project funded by the Bill and Melinda Gates Foundation. This has produced a succession of papers, many of them in the Lancet, with hundreds of contributing institutions and researchers, whose names are all listed as authors, and hundreds or thousands of citations. As long as the number of authors does not reach 1,000 each author is counted as though he or she were the recipient of all the citations. So UP gets the credit for a massive number of citations which is divided by a relatively small number of papers.

Why not just use fractional counting, dividing the citations among the contributors or the intuitions, like Leiden Ranking does. Probably because it might add a little bit to costs, perhaps because THE doesn't like to admit it made a mistake.

Then we have the country bonus or regional modification, applied to half the indicator, which increases the score for universities in countries with low impact.

The result of all this is that UP, surrounded by low scoring universities, not producing very much research but with a role in a citation rich mega project, gets a score for this indicator that puts it ahead of the Ivy League, the Group of Eight and the leading universities of East Asia.

If nobody took this seriously, then no great harm would be done. Unfortunately it seems that large numbers of academics, bureaucrats and journalists do take the THE rankings very seriously or pretend to do so in public. 

And so committee addicts get bonuses and promotions, talented researchers spend their days in unending ranking-inspired transformational seminars, funds go to the mediocre and the sub mediocre, students and stakeholders base their careers on  misleading data, and the problems of higher education are covered up or ignored.

The Decline of the University of California

Rankings have been justly criticised. Still, they do have their uses. They can identify which institutions and systems are ailing and which are in good health.

California was once the incarnation of the American dream with high wages, cheap housing, free or cheap education right through to college or even law, medical or graduate school. The University of California (UC) system was hailed as the peak of modern public research university education.

Now the state seems to have entered a period of decay. On any measure of literacy or education tCalifornia falls near the bottom of the USA. So how has this affected the public university system?

The question is now more urgent since UC Berkeley has just admitted to sending false data to the US News America's Best Colleges. Apparently the university had inflated the funds donated by alumni, a metric that accounts for five per cent of those rankings. Berkeley is now cast into the dark regions of higher education full of unranked places. It will be interesting to see what happens to applications and donations over the next couple of years. 

Questions about the performance of universities are often answered by reference to the Big Two international rankings, QS and Times Higher Education (THE). That might not be a good idea.These rankings are unbalanced with indicators that have an excessive weighting, THE's citation indicator and QS's academic survey. They are sometimes volatile and can produce  results that can be charitably described as unusual and counter-intuitive. They also rely on surveys and data submitted directly by institutions which are not very reliable. Both, however, suggest that UC is slowly and steadily declining since 2011 (THE) and 2017 (QS).

To get an accurate picture of research quality it would be better look at the Leiden Ranking, which has a consistent and transparent methodology. This too shows that there has been a steady decline in the relative global performance of the UC system. 

First, compare performance for publications, the default indicator, in 2006-9 and 2014-17. Every single campus of UC, except for Merced which is not ranked, has fallen: UCLA from 6th to 23rd, Berkeley from 23rd to 43rd, San Diego from 25th to 37th, Davis from 26th to 54th, San Francisco from 39th to 63rd,  Irvine from 88th to 146th, Santa Barbara from 168th to 28th, Riverside from 270th to 391st, Santa Cruz from 436th to 620th.

If we want to talk about quality we might look at another indicator, the number of papers in the top 1%.

Again we have a  pattern of decline although not so steep: The smallest is San Francisco from 15th to 16th, the largest Riverside from 84th to 252nd. And there is one case of  an improvement: San Diego goes from from 25th to 19th.

So far we have just looked at research. There is no global ranking that makes any serious attempt to assess teaching and learning. There are some that have indicators that might have something to do with student ability or graduate quality. The most useful of these are the Russia based Round University Rankings, which use data from Clarivate Analytics and include 20 indicators in four groups, teaching, research, international diversity and financial sustainability. 

Berkeley was ranked 52nd overall in the world and 32nd in the US in 2011. It was 197th for teaching, 5th for research, 133rd for  international diversity, and 8th for financial sustainability.

In 2019 it was still 52nd overall in the world and 27th in the USA. It had risen for teaching to 168th and for international diversity to 97th but had fallen for research to 20th and to 38th for financial sustainability.

Going into detail we see that Berkeley is improving for numbers of academic staff per student and world teaching reputation but falling for everything related to research.

Berkeley is the best of the UC campuses. All of the others except for the unranked Merced have fallen and all except for Davis have fallen for research.

It seems that UC is approaching the edge of the cliff. It is likely that the fall will get faster as Chinese students stop coming. It is difficult to see how the financial situation can get better in the foreseesble future and where the next generation of college-ready students are going to come from. No doubt there are more headlines and scandals to come.
