- Distinguish between the declarative aspect of types of lexical information in a lexicon or a
lexical database (e.g. orthography, pronunciation, syntactic category) and
the procedural aspects of how to use this information in lexicon development and for lexical access
to a lexicon or a lexical database.
- Specify an explicit lexicon model
for the intensional coverage and the structure of lexical entries and the overall structure of the lexicon, both for the lexical database and for the system lexicon.
- Define the basic lexical entry types or lexical objects (e.g. fully inflected forms , morphological stems , conceptual units), and the notation for lexical keys.
- Distinguish clearly between the status of orthography as a
property of written language,
canonical phonemic representation as a property of spoken
language, and the lexical key as a unique identifier for lexical
entries (which may often be the orthography of a canonical inflected form ,
supplemented by a serial numbers in the case of homographs).
- Define explicit specifications for the notation of orthography and for
canonical phonemic representation; for the latter, the IPA-based SAMPA alphabet is
recommended (see the following section, and Appendix B).
- First specify the lexicon model
suitable for the intended applications, then select formalisms appropriate to the model, i.e. representation conventions for the lexical database and the system lexicon.
- Do not ``programme'' the lexical information directly in an existing
formalism without first explictly specifying the lexicon model; if
possible, compile the system lexicon or pronunciation table
(wordlist) automatically from a lexical database or knowledge base.
