In Greek, adjectives are declinable words, which agree in gender, number and case with the noun they refer to. "Weird" corresponds to both forms "περίεργο" (adjective singular neutral) and "περίεργη" (adjective singular feminine).
The cooccurences of "περίεργο", "περίεργη" and "περιέργεια" (noun singular feminine), are, in most cases, common words, such as "τρόπος" (way/manner), "γεγονός" (fact), "στιγμή" (moment), "υπόθεση" (affair), "λόγος" (reason), etc. In addition, in our corpus, this token is frequently found next to "παιδί" (child) and "δηλητηρίαση" (poisoning), since some of our URLs treat the subject of food poisoning in children. Finally, we find quite a few terms used in a socio-political context, like "πολιτική" (politics), "εκλογές" (elections), "κόμμα" (political party), "Κυπριακό" (the Cyprus issue), "Ελλάδα" (Greece), "Κλίντον" (Clinton), "Ολάντ" (Hollande) and "Πούτιν" (Putin).
Note: The frequence of the adjectives "περίεργος" (singular masculine), "περίεργοι" (plural masculine), "περίεργες" (plural feminine) et "περίεργα" (plural neutral) being insubstantial, we decided not to thoroughly study these points during the analysis.
