During our initial research, we have used one form of the token "gharib" but this latter came up with new forms like "ghariba", "alghariba" and "gharaib". In the Trameur, we used a regular expression with the form "gharib" which produced a new form (singular/feminine) with and without the article: its cooccurences are "mode", "tribe", "dog", "encyclopedia", "brain" and everything that could be weird in the world (There are as well the cooccurences "dunya"/"alam" referring to the "world"). We have also found two set expressions that are commonly used "gharaib w ajaib" and "gharaib w taraif" which literally mean "Oddity and wonders".

With both of the forms "gharib" and "gharaib", the political context showed up through the words "army", "constitution", "opposition", "president", etc. Furthermore, we have the feminine plural form of the token chosen in the beginning which is "gharaib". We have the same results with both of the forms, that's why we are not going into this point thoroughly.
