Roots & patterns vs. stems plus grammar-lexis specifications: on what basis should a multilingual database centred on Arabic be built?
What it is about
The authors argue that a multilingual lexical database for Arabic machine translation should be stem-based: each entry is an actual lexeme with grammar-lexis specifications, such as the kinds of complement a verb takes, rather than a root-and-pattern database that generates stems. Their evidence is about size and fit. The Xerox analyser's roughly 90,000 stems, combined by rule, give about 72 million abstract word-forms, most of which do not occur; the stem-based DIINAR.1 database of about 130,000 lemmas gives about 6.2 million attested word-forms. Rule-generated lemmas carry little grammar-lexis information, and selection restrictions can only be stored at stem level: the verb qaraʾa does not take an enclitic plural pronoun for human objects. They keep the root as useful information for indexing, meaning and teaching, but not as the generator of word-forms.
Ideas
- I1. A selection field on each Hebrew verb entry: the kinds of direct or prepositional complement it takes (human, animate, the object marker את), so that a generator can refuse suffixed forms that break the restriction. Start with a short list of verbs in The lexicon and count the rejections.
- I2. Count the attested forms before building a generator: for
macula dict, generate full forms from the lemmas with the paradigm rules and measure the share that occurs in the Torah. The paper's ratio (72 million against 6.2 million) is the reason to measure. - I3. Roots as labels only: keep the root in
macula dictfor lookup and for grouping derived forms, but build word-forms from the stem, as the paper's footnote on roots suggests.
For Mova
I1 goes into The lexicon, with a link to complement selection in Syntax: the clause and the sentence. I2 and I3 are design checks for macula dict.
