--- abstract: |- Cet article présente une extension aux algorithmes de création de surcouche de documents hypertextuels. Il s’agit de diversifier la granularité de l’information qu’il est possible de capturer en utilisant des techniques de traitement du langage naturel. Une surcouche de document Web (web page wrapper) est une vue sur des noeuds HTML contenant une information donnée et désirée. Par exemple, dans une manchette de journal, une surcouche peut baliser le nom de l’auteur, la date ou même toutes les références à un lieu ou a une compagnie quelconque. Nous avons étendu le fonctionnement d’un algorithme de création de surcouchage afin de dépasser la limite des noeuds HTML et d’extraire de l’information du contenu textuel qui s’y retrouve. Nous appliquons cette technique à la création automatique de lexiques (liste de mots). altloc: - http://www.crtl.ca/cline05/cline05_papers/Nadeau.pdf chapter: ~ commentary: ~ commref: ~ confdates: August 26th conference: Computational Linguistics in the North-East confloc: 'Gatineau, Québec, Canada' contact_email: ~ creators_id: - pythonner creators_name: - family: Nadeau given: David honourific: '' lineage: '' date: 2005 date_type: published datestamp: 2005-11-12 department: ~ dir: disk0/00/00/46/04 edit_lock_since: ~ edit_lock_until: ~ edit_lock_user: ~ editors_id: [] editors_name: [] eprint_status: archive eprintid: 4604 fileinfo: /style/images/fileicons/application_pdf.png;/4604/1/nadeau05surcouchage%2Dfinal.pdf full_text_status: public importid: ~ institution: ~ isbn: ~ ispublished: pub issn: ~ item_issues_comment: [] item_issues_count: 0 item_issues_description: [] item_issues_id: [] item_issues_reported_by: [] item_issues_resolved_by: [] item_issues_status: [] item_issues_timestamp: [] item_issues_type: [] keywords: 'Web page wrapper, information extraction' lastmod: 2011-03-11 08:56:13 latitude: ~ longitude: ~ metadata_visibility: show note: ~ number: ~ pagerange: ~ pubdom: FALSE publication: ~ publisher: ~ refereed: TRUE referencetext: |- Ashish, N. and Knoblock, C., Wrapper Generation for Semi-structured Internet Sources, Workshop on Management of Semistructured Data, 1997.
