[Moose-dev] Hapax/CodeFu changes and example script

Hi guys, For those working in information retrieval, for example for doing td-idf ranking, you can find adapted packages: "Hapax" and "CodeFu" in the BioSmalltalk repository http://ss3.gemstone.com/ss/BioSmalltalk.html . I have translated some VW specific code to Pharo 1.4 (under Windows requires the ProcessWrapper package) and adapted some Hapax methods to work with corpus in different languages. This is an example script for a corpus in Spanish: | corpus tdm documents | corpus := HXSpanishCorpus new. documents := 'el río Danubio pasa por Viena, su color es azul el caudal de un río asciende en Invierno el río Rhin y el río Danubio tienen mucho caudal si un río es navegable, es porque tiene mucho caudal'. documents lines doWithIndex: [: doc : index | corpus addDocument: index asString with: (Terms new addString: doc using: CamelcaseScanner; yourself)]. corpus removeStopwords. corpus stemAll. tdm := TermDocumentMatrix on: corpus. Feel free to integrate to any repository. If you want to add a language just see methods with selectors including "spanish". Cheers, Hernán
