oot search
lexicon search
takes a word trunk as input, searches for it in the lexicon, and - if positive -
checks the root for "outward compatibility" (word class and combination
rules) with any inflexion or suffixation element to its right. If compatible, the
root is stored together with its derivational path for the output module.
If no root is found, or if is not compatible, the program tries to cut a (further)
suffix of the trunk.
suffix analysis -> root search (recursive)
cuts a suffix off an input string, checks this suffix for "outward word class
compatibility" and "inward phonologic compatibility" and - if both are positive
- sends the remaining trunk in standardised or phonologically adapted form to
root search, thus allowing for recursion and increasing "depth" in relation to
the number of successive derivational elements involved.
If no suffix is found, or if it is not compatible, the program progresses to
prefix analysis.
prefix -> inflexion analysis
cuts possible prefixes off the word stem, and - if phonologically compatible -
sends the remaining word trunk to normal analysis, both inflexion and
suffixation. Performed when none or only suffixed readings are found for a
given word.
makelistsuffix
establishes pointer tree for suffix-searching
makelistprefix
establishes pointer tree for prefix-searching
preprocessor
polylexical structures whole word analysis ( findword)
looks up all word sequences of up to 4 elements length in the lexicon; if
found, they are marked by '=' ligation between words. In the case of
polylexicals only listed as incorporables - i.e. without another,
autonomous reading - ligation is only performed if a form of the
incorporating verb in question is found in the left hand context.
capitalisation
word initial capital letters are substituted by '*' + lower case letter
numbers
are marked '$'. If a string starts with a number, all of it becomes a
numerical $-expression.
punctuation characters
are isolated as single characters and prefixed with '$'
abbreviations
