This paper presents a two‐phased research project aiming to improve email triage for public administration managers. The first phase developed a typology of email classification patterns through a qualitative study involving 34 participants. Inspired by the fields of pragmatics and speech act theory, this typology comprising four top level categories and 13 subcategories represents the typical email triage behaviors of managers in an organizational context. The second study phase was conducted on a corpus of 1,703 messages using email samples of two managers. Using the k‐NN (k‐nearest neighbor) algorithm, statistical treatments automatically classified the email according to lexical and nonlexical features representative of managers' triage patterns. The automatic classification of email according to the lexicon of the messages was found to be substantially more efficient when k = 2 and n = 2,000. For four categories, the average recall rate was 94.32%, the average precision rate was 94.50%, and the accuracy rate was 94.54%. For 13 categories, the average recall rate was 91.09%, the average precision rate was 84.18%, and the accuracy rate was 88.70%. It appears that a message's nonlexical features are also deeply influenced by email pragmatics. Features related to the recipient and the sender were the most relevant for characterizing email.

Il existe peu d’études récentes sur les habitudes de consommation et le comportement dans la recherche d’information musicale au Québec et au Canada. Pourtant, les études réalisées sur le sujet dans d’autres pays suggèrent que l’évolution rapide des technologies a entraîné des changements importants dans les habitudes et comportements des amateurs de musique. Il est essentiel d’avoir une bonne connaissance de ces pratiques pour concevoir des systèmes de repérage et d’exploration de la musique qui répondent aux besoins réels de leurs utilisateurs. Cet article présente les résultats d’une enquête menée auprès de 278 personnes âgées de 18 à 35 ans habitant au Québec. Les objectifs de l’enquête étaient de mieux connaître les habitudes d’achat et d’écoute de musique des jeunes adultes québécois ainsi que la façon dont ils s’y prennent pour découvrir de nouveaux artistes et de nouvelles musiques. Les résultats révèlent que les services d’écoute de musique en continu et les sites de partage de vidéos étaient utilisés par 78% des répondants. Malgré la popularité croissante de ces services, les jeunes québécois n’ont pas totalement délaissé certaines pratiques plus traditionnelles. Ils continuent de valoriser les recommandations musicales de leurs proches, d’écouter de la musique sur CD et d’acheter des fichiers musicaux, même si ces pratiques sont de moins en moins fréquentes. Very few recent studies have focused on Quebeckers’ and Canadians’ consumption and information-seeking behaviour of music for leisure. However, studies conducted in other countries suggest that the rapid evolution of technologies has resulted in important changes in practices. It is essential to gain a better knowledge of these new practices to design music information retrieval and exploration systems that meet the real needs of users. This article presents the results of a survey of 278 younger adults aged 18 to 35 living in Quebec. The objective of the survey was to increase knowledge of the music listening and purchasing behaviour of young music lovers, and to better understand how they discover new artists and new music. Results reveal that music streaming services and video-sharing websites were used by 78% of respondents. Despite the increasing popularity of these services, young Quebeckers have not entirely abandoned past practices. They still value music recommendations from friends,colleagues or relatives, listen to CDs, and purchase music files, even though these practices are becoming less frequent.
