ABSTRACT<\/h2>

Dans le cadre de la mod\u00e9lisation de dynamiques spatiales, les connaissances expertes permettent de d\u00e9finir des r\u00e8gles d\u2019\u00e9tat ou de changement d\u2019\u00e9tat. Ces connaissances contribuent \u00e0 la coh\u00e9rence des mod\u00e8les mais sont fastidieuses \u00e0 obtenir. Ce travail propose une approche d\u2019extraction automatique de connaissances \u00e0 partir de donn\u00e9es textuelles, appliqu\u00e9e aux dynamiques de changement d\u2019occupation et d\u2019usage des sols en Afrique de l\u2019Ouest. L\u2019objectif principal est d\u2019identifier des segments de texte pertinents \u00e0 partir d\u2019un corpus d\u2019articles scientifiques en anglais, en mobilisant des m\u00e9thodes de traitement automatique de la langue et d\u2019apprentissage automatique. Nous comparons deux approches de classification supervis\u00e9e avec une approche non supervis\u00e9e reposant sur la proximit\u00e9 s\u00e9mantique et montrons leur capacit\u00e9 \u00e0 identifier l\u2019information pertinente \u00e0 partir de donn\u00e9es non structur\u00e9es.<\/p><\/div>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"
