This REF specialism classification is taken from the Association of Computing Machinery (ACM) Computing Classification System March 2012 Revision, hence the use of American spelling.
Please have the REF specialism classification number enclosed in ‘< >’ as the first characters in the additional information field in the REF2 form in the form where XX is a 2 digit number in the range 01-33. If the output relates to more than one specialsim, please select the one to which the contribution is the greatest. Please identify only a single research specialism for each output.
If you cannot find the exact topic descriptor in the classification, choose a suitable higher level descriptor.
This classification is only an aid to the sub-panel and will not affect assessment of outputs in any way.
The sub-panel expect to see very few outputs classied as <33> i.e. a topic which does not fit any of the ACM topics.
Example valid classifications
<01> This paper …..
<18>This paper …..
Example Invalid Classifications
< 04> This paper … (not first characters in statement)
