Abstract :
This paper presents PAPEL, a lexical resource for Portuguese, consisting of relations between terms, extracted by (semi) automatic means from a general dictionary. After a short overview of the building process, a quantitative overview is given together with some examples. Evaluation is then presented and discussed: for synonymy, we used a public thesaurus, Tep, for the other relations, we queried Portuguese corpora through the AC/DC interface.
