ab: Summary: Currently there are increasingly more private and academic
    publications in the form of digital content on the Internet making
    extremely difficult to extract and maintain the content information
    manually. Normally, these tasks follow approximations based on natural
    language processing. This paper presents a preliminary approach for
    obtaining a semantic role labeler for Portuguese, a little explored
    aspect of natural language processing for this language. The approach
    was evaluated for the 3 most frequent semantic roles (relation, subject
    and object) with a subset of Bosque 8.0 corpus. The same approach was
    applied to an English corpus ‒ the CONLL’2004 one and its results
    were compared to the ones obtained on the CONLL’2004 shared task. At
    the same time it presents BosqueUE, a Portuguese corpus for semantic
    role labeling that can be the basis material for future research in the
    area. This corpus has the same format as the CONLL’2004 one,
    facilitating multi-language evaluations.
