As my final aim is to extract the emotion of the speaker in the audio, it would be most preferable if I could have a tool that already does basic emotion extraction. I have come across some tools like:
OpenEAR - http://geniiz.com/wp-content/uploads/2012/01/26-TUM-Tools-openEAR.pdf
YAAFE - http://yaafe.sourceforge.net/
Which could be useful for this task, but I have found that their user-base is not too much and so the tools themselves do not seem to be too user-friendly. Also, since I have still not started working with them, I wanted to know whether there are any better tools available that do the same task, in a better or easier way.
OpenEAR software provid a C++ code which work properly under Unix, it extracts more than 6000 LLDs.
- Philip Gillingham added an answer:3(As in academia) How would you evaluate a social computing system?When comes the evaluation of a social computing system, definitely one of the primary challenges is the number of participants. One obvious problem is how to evaluate the functionality of it. For instance, if you want to evaluate facebook at its early stage, it will create no meaning. Another example could be, if you ask a user in the very early stage of wikis-- whether she would like to read from wikis, definite reply will be no. An utterly rejection by the users is still the most powerful invention in time--wikis and social networking sites. Now I am interested to know, how would you evaluate a new social computing system?
An argument could be, facebook or wiki proved itself by time, but as an academia--you can not publish your invention in a good venue without an evaluation within the current review format. What is your opinion?
[ Example: Arranging conference that only targets the ingenuity ]
I think your question is a fascinating one, something that I have pondered myself for some time. A key aspect is how you want to evaluate it. In terms of utility, the main focus would be on whether and how people would use it, that is, how useful they find it. Perhaps all you can do is run an trial with a group of people, ie colleagues, students, ask for volunteers on researchgate etc.
Anyway, still thinking about it....
- David Charles Wright-Carr added an answer:91Eye Tracking Devices and Art?Eye Tracking Devices (ETDs), developed in Berlin for studies carried out in the International Space Station from 2004 to 2008, and now commercially available from Chronos Vision (http://www.chronos-vision.de/en/medical-engineering-products.html), among other companies, have potential for studying how we perceive art.
In the last decade researchers have used this technology to try to replicate Russian psychologist Alfred L. Yarbus's classic studies of eye movements and art, published in English in 1967 (Yarbus used relatively crude techniques to measure ocular fixations and saccades):
Marianne Lipps & Jeff B. Pelz, “Yarbus revisited: task-dependent oculomotor behavior,” in Journal of Vision (Association for Research in Vision and Ophthalmology), vol. 4, no. 8, August 13, 2004, article 15 (http://www.journalofvision.org/content/4/8/115, access: January 25, 2014).

Sereno, “Yarbus lives: a foveated exploration of how task influences saccadic eye movement,” in Journal of Vision (Association for Research in Vision and Ophthalmology), vol. 4, no. 8, August 13, 2004, article 741 (http://www.journalofvision.org/content/4/8/741, access: January 25, 2014).
Does anybody know of other studies using ETDs to study how we look at art?
The fourth section of the bibliography I recently translated into English and uploaded to ResearchGate includes some recent sources on eye movements: https://www.researchgate.net/publication/280949470_Art_in_the_embodied_mind_a_bibliography_%28updated_August_14_2015%29Following

What is the state of the art in integrating computational social science models? I am particularly interested in models of phenomena at varying scale (e.g., individual psychological models integrating with social level behavioral or cultural models).
You're most welcome.

I am working on a research on adaptive systems in art practice and would like to know of any media art installations or other forms of artworks (apart from music) that make use of reinforcement learning. The only examples I have been able to find thus far are works that I have authored or co-authored.

- Shian-Loong Bernard Lew added an answer:9How can we appeal to students interested in social computing and computational economics?I want to foster interest in my department's graduate program by appealing to students who want to do research in social computing and computational economics. Has anyone had good experiences with modern approaches (social media, for example)? Has it been difficult to find students with sufficiently diverse backgrounds (economics + computer science + math + sociology/anthropology/psychology)?
By highlighting the fact that simulations are occurring all around them, more so with the mediated technology we use to disguise and to veil interactions- almost an "avatar-ization" of the world. I really hope this word will be the next buzzword for the sake of our students who know it instinctively but would nonetheless have to contend with the textbook principles in order to gain this insight. The dire need therefore is not for more mature students with all-rounded experience but for more imaginative students.
To quote Albert Einstein (who had frequent flights of imagination):
“Imagination is more important than knowledge. For knowledge is limited to all we now know and understand, while imagination embraces the entire world, and all there ever will be to know and understand."Following

- Djellel Eddine added an answer:3How can we determine weight of trust in crowdsourced answers/information?The growth of the crowd sourced solutioneering phenomenon shows how people will engage and support knowledge development. However, how much confidence can we have in a crowd sourced answer, where we don't know participants, and also some people may be trying to obstruct answers?
By comparing with the other answers, you can establish a trust on certain workers. The following "ZenCrowd" technique requires:
- Run multiple repetitions for each task, ideally >=3.
- Have a bit of training data, ~5%.
- note: It was only applied to Multiple choice questions.

- Ignacio Nieto added an answer:5Is there anybody who has done research about empathy and eye tracking system?Im working for my master thesis, on the fields of: education, computer vision and empathy with children with disabilities. Im starting to program a an aplication who meassure empathy between two groups, and I'm very interested to measure empathy with some device that can just sense the eye.
Hello Saima I dont know Tobii T120 eye tracker, the one they use for the experiment (van Rijn mail, Barendse, Goozen, Swaab), but it seems, that its all done. Using that technology you can report a heat map without programming it for example
In these sense the authors said about the experiemnt
"Gaze data were processed using Tobii Studio (3.0), using the Tobii I-VT fixation filter. The ‘Dynamic AOI (Area of Interest)’ tool, using freeform shapes, was used to draw AOI's. Dynamic AOIs were grouped into the following categories: facial features (without mouth and eyes), eyes, mouth, body, objects and other (i.e. on the screen, outside other AOI's)."
Also you can work with the Eye Tribe
https://theeyetribe.com/ and test heat map making an account in Eyeproof
When you referer to: "mathematical computations that eye tracking system", what you will need to finish your study? In my case is a little bit more complex Im finishing I hope a first aproach of my research the next week a theorical one. Then I rebuild a software that can detect bad words written by childs with aphasia / SLI. Finally I will meassure empathy. But all works and people are welcome!
- Trevor G Bond added an answer:7Classical test theory and probabilistic test theory: supplementary or contradictory?I imagine the following scenario: You have 12 items that measure 2 sub dimensions of a construct, 6 items each construct.
Say the construct is happiness, the sub dimensions were eudaimonic and hedonic happiness. You find the 2 sub dimensions in an exploratory factor analysis, just as theory says.
But the Rasch model does not fit each sub dimension. It fits when you analyze ALL items at once. Can we now combine these insights? E.g. we measured each sub dimension reliably and therefore we can assume that items 1e-6e assess eudaimonia, 1h-6h measure hedonia. These items are then labeled with the respective dimension. In Rasch analysis with all items we would then find that 8.3% (=100%/12) participants were measured well per item. Hedonic item 1h has the largest logit, eudaimonic item 1e the second largest, hedonic 2h the third largest, eudaimonic 2e the fourth etc.
Could we now argue that in the case of happiness the item 1h assesses the most happy persons and this happiness is of hedonic nature?
In case I messed it up or anything is not clear, please ask.
But MIRT is more useful at the estimation of groups, not individual personsFollowing

- Tahir Sousa added an answer:7Are there new ways of identification of clauses in sentences?What are the best ways to identify clauses in a sentence? I would like to not only extract clauses from a sentence but also identify the type of clause it is. i.e. dependent or independent clause.
A clause is grammatically defined as the part of the sentence having a subject and predicate. For example consider the sentence:
"In fact, the last time he tried to lose weight, he ended up actually gaining weight."
"He tried to lose weight" is a dependent clause while,
"He ended up actually gaining weight" is an independent clause.
I have come across some results from CONLL but these are pretty old (2001), so I was wondering whether anyone has an idea to some better work done on this subject.Thanks for all the suggestions everyone!
