## My second paper reaches exactly 100 citations

August 29th, 2012

On August 3, 2010 I wrote that my first paper reached exactly 100 citations on Google Scholar. Now my second publication, a UIST 2004 paper, has exactly 100 citations as well. Coincidently, we will host UIST 2013 in St Andrews next year.

## List of questionable open access publishers

July 11th, 2012

I have previously written about how some open access publishers spam researchers for submissions and demand high fees to publish papers and book chapters (here, here, here and here).

There is a website that attempts to list such open-access publishers:

As I suspected, the website lists both InTech and Bentham.

## Internet research and ethics: inducing bullying on social networks considered okay?

March 27th, 2012

The Chronicle of Higher Education reports that Dean Terry and  Bradley Griffith at the University of Texas at Dallas have created a Facebook app called EnemyGraph.

The basic idea is an introduction of a “dislike” feature on Facebook.

One can debate the merits of introducing this mechanism. I will not. Instead I’d like to comment on this quote from graduate student Bradley Griffith who worked on the project:

Mr. Griffith, though, expected some sparks to fly. He said he is disappointed that EnemyGraph hasn’t been used more for what he called “bullying and high-school dramas.” He feels Facebook’s current system is artificially nice, so he wants to “encourage people to confront their negative relations to each other head-on as a sort of conversation.” He argues that “when you keep groups or people separate, you can actually cultivate more enmity.”

Seriously? He is disappointed that their research project did not result in instances of bullying? Is he unaware that the consequences of bullying on social networks can be severe, including suicide?

This quote makes it sound like one of their working hypotheses was that their intervention would induce bullying on social networks. If this was the case, it puzzles me how this project managed to get IRB approval. Regardless, this quote is yet another sad example of how Internet research is carried out with little or no consideration of the very real risks of causing people harm.

## IEEEtran.bst and the mysterious missing item

March 22nd, 2012

If you were naive like me and downloaded the IEEE conference template from IEEE’s website you may have experienced a puzzling error:

“Something’s wrong–perhaps a missing \item”

There is no point in trying to fix this as the reason this is happening is because the IEEE website gives you a template with an old IEEEtran.bst file. Go download the new version of IEEEtran.bst here from CTAN. Then delete all intermediate files (.aux, .bbl, etc.) and recompile. This worked for me.

## The Chronicle writes about open access spam journals

March 7th, 2012

I have blogged before about how low-quality open access “publishers” indiscriminately spam researchers for manuscripts for the most ridiculous journals and “edited books” (here, here and here). The peer-review and quality-control appears to be minimal and the publication fees are outrageously high.

Now The Chronicle of Higher Education has an article about how ‘Predatory’ Online Journals Lure Scholars Who Are Eager to Publish. It is excellent and very important this is brought to attention. There is of course nothing wrong with a desire to communicate research in the form of open access articles. However, having tax-funded researchers paying ridiculously high fees for someone essentially hosting PDF files without any real peer-review whatsoever is a huge waste of tax money. Even worse, having researchers passing these “publications” off as properly peer-reviewed scholarly articles is essentially a form of academic misconduct in my view.

## The beginning and the end of the world

October 6th, 2011

Having moved to St Andrews about five months ago I felt I should try to read up on the town’s rich history. However, I felt that the first book I picked up to read was just too dry to be interesting (it started with the ice age…). What I missed was a story about the people of St Andrews. Surely a 600-year old university town must have some interesting stories to tell from its past?

Therefore I was delighted when I read a review in the Guardian of a recently published book called The Beginning and the End of the World: St Andrews, Scandal, and the Birth of Photography by Robert Crawford, a professor in the School of English at the University of St Andrews.

This fantastic book paints a vivid picture of life within the University of St Andrews in the 19th century. It tells the tale of Sir David Brewster, an extremely distinguished scientist at the time and Principal of the United College in the University of St Andrews. This man, who among his many achievements invented the kaleidoscope, helped start the Literary and Philosophical Society of St Andrews. Despite St Andrews awkward location (it took about a day to travel from Edinburgh to St Andrews at the time), the Lit & Phil managed to attract individuals who went on to have a profound impact on both the British society and the world at large. Among other things, their ability to keep up with the research frontier on photography resulted in St Andrews becoming the first town in the world to be comprehensively photographed.

I very much recommend reading this fascinating book. It was a great pleasure to read this well-written and thoroughly researched account of 19th century St Andrews.

## More open access spam

October 6th, 2011

Relating to a previous post on academic spam it seems the spammers from inTech now have competition in the open access “book chapter” business.

I just received the following email:

Dear Per Ola Kristensson,

On behalf of iConcept Press, I would like to invite you to submit a paper
to our new book project under the working title “Handbook of Pattern
Recognition: Methods and Application”. The editor of this book is Khalid
Hosny. The book description can be found at:

http://www.iconceptpress.com/01/site/publication.viewPapers.php?publicationID=BK020A

We notice that you have some publications related to this book project. For
instance, we are interested in your paper entitled “Parakeet: a
demonstration of speech recognition on a mobile touch-screen device
(2009)”. (Please note that we are not asking you to republish this paper).
You are welcome to submit an extended/expanded version of this paper, or
any work that is related to this book. We expect each chapter has a minimum
of 16 pages.

All iConcept Press books are published as hard copy with ISBN and as open

http://www.iconceptpress.com.

Since we are open access, we would like to ask our authors to contribute
part of the publication expense. This publication fee might be
waived/reduced if: Most authors are from countries that are not classified
as high-income economies
accepted manuscript is USD$38/page for the first 16 pages and USD$18/page
thereafter. The corresponding author of each paid chapter will receive one

I sincerely hope that you would accept the invitation and that you support
the open access idea.

Next step:
2. Submit a tentative abstract and title via our online submission system
(http://www.iconceptpress.com/01/site/process.register.php) by: 10 Nov
2011
3. Upload a full chapter by: 15 Jan 2012

Regards,

iConcept Press
Web: www.iConceptPress.com

Again, I wonder why I would pay for an open access book chapter? These chapters seem to undergo minimal (if any) peer review (I have never been asked to review any and I have never heard of anyone else being approached either) so all an open access book chapter amounts to is a PDF document hosted on a website. I might as well make the text available on the web myself. For free.

## SLPAT 2011 workshop report

July 31st, 2011

Yesterday I attended the Second Workshop on Speech and Language Processing for Assistive Technologies (SLPAT) in the Informatics Forum at the University of Edinburgh. It was held in conjunction with ACL’s annual conference on Empirical Methods in Natural Language Processing. Last Thursday I had presented a paper on our work on AAC language modelling work at EMNLP. Therefore, even though I did not have anything new to present at the workshop, the SLPAT workshop was of high interest to me.

I have attended quite a few workshops before and my impressions so far have been mixed. Sometimes workshops fail to attract high-quality papers. Other times the organisation is in chaos. Very rarely do the workshop organisers manage to get everything right. Therefore I was very pleased to note that SLPAT 2011 managed to both attract high-quality workshop papers and deliver on an ambitious workshop schedule that packed the day with talks interwoven with user panels, posters and demonstrations.

Besides the talks, two other features stood out. First, the workshop had two ambitious poster & demo sessions. Demonstrations included a Lightwriter, a popular text-to-speech AAC device. I had never used one before and it was instructional to learn how it was designed. I also think it was a brilliant move to invite the AAC vendors Toby Churchill and Tobii to the workshop. I think researchers in AAC have a duty to try to interface with industry and government so that our research results can translate into actual benefits for end-users.

Related to this point, another feature that stood out was the AAC user panel. The organisers had invited AAC users to deliver prepared speeches about their reflections and ideas of AAC based on their own first-hand experiences with AAC devices. Thereafter the audience had an opportunity to ask questions. It was a very instructional session and also a reminder to me about just how much AAC devices can still be improved. I was also amazed by the eloquence of some of the talks delivered.

In summary, SLPAT 2011 was a highly ambitious and well-organised workshop. It was run just as well as a full conference, albeit for a smaller and perhaps more dedicated audience. I had a great time, I met lots of interesting people and I learned a lot. I will definitely try to attend the next workshop.

## AIED 2011 conference report

July 12th, 2011

Queen Street, Auckland

I recently attended the 2011 Artificial Intelligence in Education (AIED 2011) conference in Auckland, New Zealand.

The main focus of the AIED conference series is various approaches to designing and evaluating intelligent tutors. An intelligent tutor is basically a computer program that uses AI techniques (such as planning algorithms) to teach students new concepts or techniques based on a model of what the students already know, or are supposed to know. The conference is quite old, this was the 15th biannual conference. The conference is organized by the International AI in Education Society. It also seems that the AIED conference is liaised with the Intelligent Tutoring Systems conference (ITS) so that ITS runs every even year and AIED runs every odd year. Collectively ITS and AIED publish the vast majority of new research in the intelligent tutoring field.

I was at AIED to present a poster on the first steps towards designing intelligent tutors for text entry methods. The idea is to increase user adoption of novel text entry methods by using highly effective and engaging intelligent tutoring. I wouldn’t classify myself as an intelligent tutoring researcher so attending this conference was a good opportunity to get an insight into the field’s frontier.

AIED conference proceedings

The conference was held at the Faculty of Engineering at the University of Auckland’s city campus. The conference had a poster session, an interactive event, and three parallel paper tracks. In my opinion the overall organization of the conference and the program worked out very well.

The presented papers fell into three categories: systems, user studies, or data mining. I learned that the latter is apparently so popular that people have felt the need to start a conference on just that, the Educational Data Mining conference (EDM). I also found that machine learning is becoming increasingly popular in intelligent tutoring systems. Some of the machine learning techniques people used were POMDPs and Bayesian models. An interesting concept I didn’t know about before was Open Learner Models (OLMs). OLMs exploit the fact that while a student is using an intelligent tutor the system develops a model of the student. The idea behind OLMs is to figure out how to present the entire model (or aspects of it) to the student. Presumably this can aid the student’s learning.

Some of the papers presented intrigued me. In particular a paper on motivational processes seemed to point in good directions and another paper on confusing students (!) had led to some rather surprising results. I also found out that another active research area is authoring tools for ITSs, some which use techniques from the end-user programming field.

Overall I very much enjoyed going to this conference. It was refreshing to learn about an area of research outside of my comfort zone. Time will tell if I will submit a full paper to AIED 2013!

## Firefox 4 and the disappearing status bar: on forcing interface redesigns upon users

May 30th, 2011

Update (June 24, 2011):

Firefox 5 brought back the status bar, at least for Windows.

So Firefox prompted me to update to the new version, which I did. And the first thing I noticed was that the menu bar was gone. However, an option enabled me to get it back relatively quickly.

The second thing I noticed was that the status bar was gone. As it turns out, there is no option to get it back, and this is by design.

This puzzles me because there are at least three pieces of information I am relying on the status bar for:

1. Which URL I will load if I click on a link.
2. Whether or not I am on a secure link (the padlock icon).
