摘要: Personalization of support for information seeking depends crucially on the retrieval system's knowledge task that led person to engage in seeking. Users work during search sessions satisfy their goals, and activity is not random. To what degree are there patterns user sessionsq Do reflect user's situation as moves through under influence his or her goalq these aspects different types information-seeking tasksq Could such identify contexts within which takes placeq investigate questions, we model sequences behaviors two independent studies (N = 32 users, 128 sessions, N 40 160 sessions). Two representations used. One based page use; other a cognitive representation acquisition derived from eye movement service reading process. considered journalism tasks; concerned background research genomics using tasks taken TREC Genomics Track. The differed basic dimensions complexity, specificity, type product (intellectual factual) needed achieve overall goal. results show similar observed at both use levels. layers able distinguish between ways and, some degree, levels difficulty. We explore relationships difficulty discuss events session. User can be least partially server-side logs. A focus may contribute development systems better personalize experience.
