  1. The DictionaryofItalianCollocations: Design and Integration in an Online LearningEnvironment Stefania Spina UniversityforForeigners Perugia, Italia

  2. The Dictionary of Italian Collocations • Part of APRIL project (“Personalised web environmentforlanguagelearning”) • NLP resourcesas a supportfor the lexicalcompetenceofstudentsofItalianwithin a VirtualLearningEnvironment(VLE). LREC 2010 - Stefania Spina - The Dictionary of Italian Collocations

  3. Presentationoutline • background and motivation • reference corpus • methodology • dictionary compilation • integrationwithin VLE LREC 2010 - Stefania Spina - The Dictionary of Italian Collocations

  4. Background • Complexityof MWU: • differentsyntactic and semanticprofiles • prototypicalfeatures: • semantic (non-)compositionality • (non-)substitutabilityofcomponentsbysemanticallysimilarwords • (non-)insertionofexternalitems • continuum ratherthan definite categories LREC 2010 - Stefania Spina - The Dictionary of Italian Collocations

  5. Motivation: collocations in SLA • improvelearnersfluency • examplesfromItalianleanercorpora • preoccupata per l’esame vado a prendere una doccia (Vietnam) • Fare la doccia “take a shower” • ho dimenticato la macchina di fotografia (China) • Macchina fotografica “camera” • non-nativespeakers and L2 vocabulary: first single words, then more extendedchunks • trend tooveruse the creative combinationofisolatedwords • Sinclair’s open choiceprinciple LREC 2010 - Stefania Spina - The Dictionary of Italian Collocations

  6. DICI • collocationsrequirespecificpedagogicalattention • DictionaryofItalianCollocations(DICI) • itiscorpus-based; • itis a learner-orientedtool: listof the most common Italiancollocations, classified on a frequencybasis; • itisalsobased on statisticalmethodologies (dispersion in the differenttextualgenresrepresented in the corpus). LREC 2010 - Stefania Spina - The Dictionary of Italian Collocations

  7. Reference corpus • Perugia corpus: POS-tagged, lemmatized LREC 2010 - Stefania Spina - The Dictionary of Italian Collocations

  8. Extractionbased on POS sequences • Analysisofexistinglistofcollocations: • 150 different POS sequences • 10 mostproductive (75%) LREC 2010 - Stefania Spina - The Dictionary of Italian Collocations

  9. Experimentalmethodology: 4steps • extractionof candidate collocationsfrom corpus; • filteringof the candidate collocations: frequency; • filteringof the candidate collocations: dispersion; • filteringof the candidate collocations: manual • 6POS sequences • 12-million-word sample • 4 corpus sections LREC 2010 - Stefania Spina - The Dictionary of Italian Collocations

  10. Collocationsextraction + frequency • IMS Corpus Workbench • removingall the candidateswithfrequency = 1 • 41643 collocations LREC 2010 - Stefania Spina - The Dictionary of Italian Collocations

  11. Dispersion • Examples: • Aggrottare la fronte “tofrown” (fiction) • Vincere le elezioni “towin the elections” (press) • Dare una definizione “togive a definition” (academic prose) LREC 2010 - Stefania Spina - The Dictionary of Italian Collocations

  12. Dispersion • Juilland’sDvalue (Juilland - Chang-Rodriguez, 1964) LREC 2010 - Stefania Spina - The Dictionary of Italian Collocations

  13. Dispertion + frequency • Dvalue: combinedwithfrequency = usage • U = FD • Usage value ≥ 2: 2047 candidate collocations • Manualselection. Finalresult: • listof1553 word combinations = dictionaryentries LREC 2010 - Stefania Spina - The Dictionary of Italian Collocations

  14. Collocationslist LREC 2010 - Stefania Spina - The DictionaryofItalianCollocations

  15. Compilation of the Dictionary • Lexical database enrichedwithtwokindsof data: • visibleto the learner (client output) • definition, examples, part-of-speech, syntacticcontextofoccurrenceofcollocations • tobeprocessedbyotherapplications (server) • internalsyntacticconfigurationforautomaticrecognition LREC 2010 - Stefania Spina - The Dictionary of Italian Collocations

  16. DB integration in the VLE • VirtualLearningEnvironment: • web applicationspecificallydevotedtolanguagelearning • LELE (Linguistically-EnhancedLearningEnvironment) • providelanguagelearnerswithadditional NLP resources, in ordertoimprovetheirlinguisticcompetence • receptive and productivelearningactivitiesconcerning the recognition and the activeuseofcollocations LREC 2010 - Stefania Spina - The Dictionary of Italian Collocations

  17. LELE Features • toautomaticallyrecognize and highlightmulti-wordunits in writtenItaliantexts; • to show additionallinguistic information about the selectedcollocations; • to generate collocationtestsforcollocationalcompetenceassessmentofsecondlanguagelearners. • … LREC 2010 - Stefania Spina - The Dictionary of Italian Collocations

  18. LELE scheme VLE DB + tagger browser server client LREC 2010 - Stefania Spina - The Dictionary of Italian Collocations

  19. Conclusions • Nextsteps: • samemethodologyto the whole corpus, forall the 10 selected POS sequences • test of LELE system withstudents: startingjanuary 2011 • Furtherresearch • refinestatisticalmeasures • assigncollocationstodifferentlevelsofcompetence • othertools (productivetasks) LREC 2010 - Stefania Spina - The Dictionary of Italian Collocations
