Their purpose is to function as a structure for international cooperation on a subject. Its terms of reference, objectives, and a list of its members can be found below. A still growing bibliography of more than 200 items can be found on this server. Starting from relative simple rounding schemes, sophisticated and sometimes time consuming algorithms have been devised. Despite the large effort spent by many groups from all over the world in devising various schemes, knowledge about their theoretical foundation, and how the schemes are related to each other, is still lacking.
Different terminology is used and comparisons between methods are rare.
Due to a lack of knowledge about the various methods, the implementations used in the comparisons are not always complete, thereby making the test results unreliable. Moreover, results reported of one particular method, are often difficult to relate to the results of another method, due to lacking knowledge of the characteristics of the data and the type of computer that was used. The outcome of this Special Study Group should be A further understanding of the problem of ambiguity resolution. Understanding how the various algorithms work, and how they are related to each other. Advantages and disadvantages of each class of methods.
