    Abstract
    Most information systems share a common assumption: information seeking is discrete. Such an assumption neither reflects real-life information seeking processes nor conforms to the perspective of phenomenology, "life is a journey constituted by continuous acquisition of knowledge." Thus, this study develops and validates a theoretical model that explains successive search experience for essentially the same information problem. The proposed model is called Multiple Information Seeking Episodes (MISE), which consists of four dimensions: problematic situation, information problem, information seeking process, episodes. Eight modes of multiple information seeking episodes are identified and specified with properties of the four dimensions of MISE. The results partially validate MISE by finding that the original MISE model is highly accurate, but less sufficient in characterizing successive searches; all factors in the MISE model are empirically confirmed, but new factors are identified as weIl. The revised MISE model is shifted from the user-centered to the interaction-centered perspective, taking into account factors of searcher, system, search activity, search context, information attainment, and information use activities.

    Abstract
    Successive information searches are fairly common. To enhance the understanding of the behavior, this study attempted to improve both the descriptive and explanatory power of the Multiple Information Seeking Episodes (MISE) model, a conceptual model characterizing factors affecting successive searches. It empirically observed how the key factors in the information seeking process in the MISE model evolve over multiple search sessions and explained how those factors are affected by other factors associated with searchers, search activity, search context, systems, information attainment, and information-use activities. The validated and enriched MISE model can be extended to serve the basis for future studies in other complex searches process such as multi-tasking and collaborative searches, and can also help identify problems that users face and thus derive requirements for system support.
