We present the JAKOB lexicon, a semantically rich German lexical resource, and its
migration to the OLIF format (Open Lexicon Interchange Format). This lexicon is part of a
web-based text and narrative analysis application. The JAKOB narrative analysis is a
qualitative research tool to systematically analyze patient.s narratives. It conceptualizes
narratives as dramaturgically-constructed linguistic productions and interprets them with
regard to the un-conscious conflicts of the narrator contained there in. In this process,
narratives are extracted from transcripts, then a linguistic analysis is performed, and after
that the vocabulary is encoded according to predetermined psychological conceptual
categories incorporated in the JAKOB lexicon. The need for the proper treatment of multiword
units in the JAKOB project made OLIF a reasonable target format. OLIF is wordsense
oriented and allows a broad linguistic description-syntactical, morphological, and
semantic-for each lexical entry. The OLIF data categories and attributes are well defined
in the case of German but it turned out that the data-category labels in OLIF aren.t
specified very clearly sometimes. In addition to that, there are few resources that prove
their practical use. In a corporate project, the lexicon was half-automatically reassessed
and finally migrated. OLIF is an open XML-based standard for structuring lexical data and
provides a rich choice of linguistic categories and predefined values. Multi-word entries
represent an essential improvement for the JAKOB application. The narrative texts
represent spoken language; therefore the utterances aren.t well formed, in most cases, and
not eligible for a standard syntactic analysis. We use a construction-grammar approach to
gather the sense of multi-word expressions in the text and to match them to lexicon entries
with their corresponding conceptual categories. We use multi-word entries as containers
for constructions-form-meaning units-like idioms and collocations. Further investigations
will show to which extent more general constructions can be lexicalized. Our project goal
is to improve precision in coding the JAKOB narratives. We decided to create an OLIF
database, using the XML schema as the basis for the database structure. Thus, import and
export of OLIF data is straight-forward. The implementation is object-oriented and solely
based on open source software using PHP / MySQL.
