- Djellel Eddine added an answer:How 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:Is 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:Classical 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

@Rodrigo you will get a better response if you write stuff that has not been passed through a Chinese version of Google Translate. It's completely incomprehensible. Please take care.
I''ll help you out.
(No, I haven't killed a bird - or watered a horseradish; similes do not translate).
@Robert - what Rodrigo is trying to evaluate is how secure people think TrueCrypt is against a certain class of attack. Of course, this is an intrinsically doomed way of going about getting stats. Once people have their attention drawn to the idea that they may be vulnerable to some problem they know nothing at all about, they're not going to play.
Then there's the problem that about 0.1% of the readers will have even heard of the utility.
Perhaps one can ask instead: have you ever changed the password on a truecrypt volume, and if so, why? Was it because you always use the same password for everything and it got compromised? So you decided to start using a new password everywhere?Following

- Don Knox added an answer:What are some good tools for emotion extraction from audio features?I'm looking for a good tool to extract audio features like Mel-frequency, energy, etc. from a sound file. 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.We use the MIR Toolbox, Psysound, Marsayas.Following

- David Charles Wright-Carr added an answer:Eye 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?Thanks for your thoughts on this, Efstathios, and for the link. At first glance this looks like an extraordinary source. For now I am just approaching this field, together with cognitive sciences, neurosciences and neuroaesthetics, as sources of information for building a stronger theoretical base for understanding art history and contemporary art, with an eye on its possible applications in the creation and production of art (objects and acts). When I look around, I see a lot of people using theory from two generations ago, so I feel the time has come to make an effort to incorporate the recent explosion of knowledge in these relatively new fields into my academic work and to help my students to understand and to use them in theirs.
For now I have a pilot program, with one brave undergraduate student, in my university's summer research program. Next year I hope to expand this into a course for master's and doctoral students in arts, including the preparation of a text in Spanish. Hopefully down the road I can form an interdisciplinary team and do some serious research, perhaps involving eye-tracking. Meanwhile there is much to be read and processed.
I think the questions you ask in your third paragraph would be an excellent starting point for an eye-tracking study. There are a lot of other variables that could be explored, for example the possibilities of chromatic contrasts in attracting fixations to specific locations in the visual field.Following
- Tahir Sousa added an answer:Are 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!

What you don't achieve in breadth, you can in depth.Following
- Nasim Mahmud added an answer:(As an 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 ]To me it seems interesting as well as alarming that there is no reply in "researchgate," a social networking plat form when the question is about evaluating social computing systems! Alas! Can it be wake-up call?Following
- Reza Farrahi Moghaddam asked a question:Is there any legal problems for a web site that anonymously collects reports of non-emergency traffic infringements?The idea is to create a web site to collect non-emergency traffic infringement reports without any implication on the contributors. The human by far is the most advance sensing system, and human societies can be seen as distributed sensor networks (DSNs). This web site sources on this by making contributions anonymous and untraceable. Also, the collected data will not be published to public. Instead, the authorities of related cities and municipals can ask to have access to the data.
The question is whether the web site owner (collector) or the people who send the reports (contributors) are vulnerable to face legal actions or lawsuits? If yes, does this apply to all regions and countries? Or are there some regions in which this concept can be legally implemented?
Also, if you know an already implemented version of this concept, please share the information.Following
