10 Unknown simple words & Analyzed tokens (PFX & SFX) 323,072 unknown unigrams in Spanish Webpages 68,818 candidates to new simple-word lexical entries PFX.grf (99)6.380 analyzed tokens SFX.grf (54)271 analyzed tokens

11 6th INTEX Workshop Sofia, Bulgaria 28-30 May 2003 Three different classes of Analyzed tokens First case: –The constructed form is lexicalized –Then, we need to add a new, independent entry e.g. prelavado (prewashing), macrofiesta...

12 6th INTEX Workshop Sofia, Bulgaria 28-30 May 2003 Three different classes of Analyzed tokens Second case: –The constructed form is lexically conditioned –Then, it must be explicitly indicated in the “Lexical Functions” area of the microstructure of the lexical basis e.g. superamigos, ??archiamigos, ??hiperamigos, *maxiamigos “somos superamigos” = “somos muy amigos”, “somos amigos íntimos” (close friends) Lexical Function = Magn (close friends, heavy smoker, confirmed bachelor...)

13 6th INTEX Workshop Sofia, Bulgaria 28-30 May 2003 Three different classes of Analyzed tokens Third case: The constructed forms is actually a constructed form ! In other words, a lexical unit of the dictionary plus a prefix that expresses a value of the actualisation of this lexical unit: tense, aspect, diathesis, negation or quantification. The bad news: In order to generate reasonable hypothesis, we need to represent some linguistic constraints.

24 6th INTEX Workshop Sofia, Bulgaria 28-30 May 2003 Conclusions and Perspectives An unigram can convey, in a cumulative form, information about actualization, lexical functions and argument structure. The mechanism is, in someway, recursive: auto-des-programar, auto-des-program-able... mega-rollitos de primavera... We need an integrated description of morphology, syntax and semantics !
