Metaphor is an inseparable part of communication in Arabic language. Over the past years,
Arabic metaphors have been increasingly used in online communication, which has drawn
attention of researchers. Arabic metaphors in online context have been evolving and show
distinct features, reflecting the need for speedy online communication compared to traditional
written forms. While Arabic metaphors have intrinsic ambiguity of word sense, the metaphors
used online present an even higher challenges for accurate interpretation of their true meanings
in their contexts. For example, no reliable resources can be found for online variants of Arabic
metaphors for interpretation, newly emerging metaphor structures are not registered in standard
Arabic literature, they can have different writing styles in different Arabic dialects, and
frequently appearing typos etc. Therefore, we need a corpus that reflects online Arabic
metaphor usage annotated with their key features for the investigation of Arabic metaphor
usage in online context and to develop tools for identifying and classifying them. However, as
far as we are aware, there is no such corpus publicly available yet.
