    Abstract

    We present an explorative study for the (semi-)automatic categorisation of actions in Dutch multimodal first aid instructions,
    where the actions needed to successfully execute the procedure in question are presented verbally and in pictures. We start
    with the categorisation of verbalised actions and expect that this will later facilitate the identification of those actions in the
    pictures, which is known to be hard. Comparisons of and user-based experimentation with the verbal and visual representations
    will allow us to determine the effectiveness of picture-text combinations and will eventually support the automatic generation
    of multimodal documents. We used Natural Language Processing tools to identify and categorise 2,388 verbs in a corpus of 78
    multimodal instructions. We show that the main action structure of an instruction can be retrieved through verb identification
    using the Alpino parser followed by a manual selection operation. The selected main action verbs were subsequently
    generalised and categorised with the use of Cornetto, a lexical resource that combines a Dutch Wordnet and a Dutch Reference
    Lexicon. Results show that these tools are useful but also have limitations which make human intervention essential to guide
    an accurate categorisation of actions in multimodal instructions.
