Evaluating the Overlap of User Preferences with Search Engine Performances using UCISE

Abt, Raphael; Haigis, Jonathan; Stappen, Christina

Abstract:
Background: The assessment of information systems such as Search Engines (SEs) from the users’ perspective needs to assure that it does not introduce a bias towards the systems’ technical implementation. Instead, the socio-technical nature of SEs and a users’ contextual evaluation based on previous experiences should be at the center of attention.
Objective: Therefore, we introduce a methodological approach for a User Centered Information System Evaluation (UCISE) and apply it to a SE evaluation. This approach allows for comparing selected SEs based on a derived set of user-based evaluation criteria.
Method: Our methodology consists of four steps, including a criteria synthesis, a criteria importance assessment by a large-scale survey and an expert assessment of selected SE performances regarding the user-based criteria. In the final step, we visualize the fit between the users’ criteria preferences and the assessed SE performances.
Results: The first step of our methodological approach enabled the synthesis of a set of ten criteria for the SE differentiation from user-perspective. Of these ten criteria, only the three criteria ‘search result quality’, ‘ease of use’ and ‘privacy protection’ emerged as being perceived as ‘extremely important’ or ‘important’ by the user. ... mehr
