The attribute LEX (Lexical category) follows the general idea that the words of language may be classified either as lexical heads or as functional heads, and that these categories are actually derived from the combination of two primitive categorial features (N, for nominal, and V, for verbal, as described in Chomsky, N. 1981: Lectures on Government and Binding), as follows:
N (nominal) = +N,-V
V (verbal) = -N,+V
J (adjective) = +N,+V
A (adpositions) = -N,-V
In addition to these open-class lexical heads, we have also closed-class functional heads (such as D, for determiner; I, for inflection; and C, for complementizer), which are used to describe aspects of the grammatical structure of a given language. In the UNLarium framework, we have also added some semi-lexical categories (such as pronouns and numerals) and we have differentiated between prepositions (P) and adverbs (A), which are normally understood as belonging to the same lexical category (A). This was necessary because we plan to derive POS (which has mainly to do with the morphological and the syntactic behavior) from LEX (which has been associated rather to the semantic). For the time being, however, LEX is normally used to classify UWs, where POS is used to classify natural language words.
