Any task that can be represented as an algorithm can be done by a computing machine. In marking papers, there should be some sort of marking scheme or rubric which markers use to make scoring decisions and which should provide consistency across markers. That rubric is an algorithm which, in theory, could be used as the basis for machine grading.<br /><br />Now, of course, it is easier to do with some types of marking than with others (it's been done with multiple choice and short answer questions for a long time now). Essays are more difficult because the range of possible responses is very high and the rubrics less definite. But I think it could be done, if you have enough samples of essays which we already know the mark for. The thing you need is a neural network (http://en.wikipedia.org/wiki/Neural_network) which you can train to do your marking.<br /><br />Good luck!<br />DeanSlowBowhttps://www.blogger.com/profile/00242581760479760047noreply@blogger.comtag:blogger.com,1999:blog-3529806302633025309.post-38575088074466389002012-04-17T08:06:53.430-07:002012-04-17T08:06:53.430-07:00That is really time consuming Adria.

I just got tired thinking about thinking if this could be a reality one day. Even if it did come to be true .. how will this grading and reading take place, do we have to give some criteria to the computer, are we going to input the rubrics, what if there is a statement or a paragraph that is written in wrong language, how the machine will correct this and grade it .. I got headache already !!! Nice thought Adria.Manal Emamhttps://www.blogger.com/profile/13981875230816093568noreply@blogger.com
