Assessors' search result satisfaction associated with relevance in a scientific domain

In this poster we investigate the associations between perceived ease of assessment of situational relevance made by a four-point scale, perceived satisfaction with retrieval results and the actual relevance assessments and retrieval performance made by test collection assessors based on their own genuine information tasks. Ease of assessment and search satisfaction are cross tabulated with retrieval performance measured by Normalized Discounted Cumulated Gain. Results show that when assessors find small numbers of relevant documents they tend to regard the search results with dissatisfaction and, in addition, they obtain lower performance for all document types involved, except for monographic records.
