متن کاملL'expressivité des modèles de recherche d'informations précises
RÉSUMÉ. Nous proposons dans cet article de modéliser l’expressivité des systèmes de recherche d’information (SRI). En effet peu de cadres de modélisation sont disponibles pour spécifier les SRIs. Nous proposons un tel cadre sur lequel nous portons un intérêt particulier à la modélisation de l’expressivité, c’est-à-dire à ce que ce modèle est capable de décrire. Le niveau d’expressivité est impo...
متن کاملÀ la recherche des paramètres des modèles de RI
We address in this study the problem of estimating standard IR model parameters on new collections for which no relevance judgements are available. To do so, we rely on past collections with relevance judgements and introduce a new, collection independent query representation. From this representation as well as from past collections, we learn a regression function linking queries to parameter ...
