These methods have been applied with default values and no feature normalization mainly using Weka3 [27]. Tuning is left for future research. To test the accuracy of the models, 10fold cross-validation was used. The results of these supervised ML methods, combining the best 18 feature variants (Table 1) incrementally, as explained above, are shown in Table 2. Table 2. 29% accuracy which is better than the best result for any of the other ML methods. 28% accuracy. Nonetheless, the use of any of the ML methods achieves better results than any one of the feature variants.

3 Features for Abbreviation Disambiguation Ambiguous abbreviations have several senses, but within a specific context, such as a sentence, abbreviations usually have only one specific sense. To find the correct sense of any abbreviation, 18 different features were defined. Each feature is described as a rule and implemented as a baseline method in the developed system. These methods are divided into 3 distinct groups: Statistical attributes (2 methods), Hebrew specific attributes (1 method) and Contextual relationship attributes (15 methods).
