The present invention discloses CrowdScape, a system that supports the human evaluation of complex crowd work through interactive visualization and mixed initiative machine learning. The system combines information about worker behavior with worker outputs and aggregate worker behavioral traces to allow the isolation of target worker clusters. This approach allows users to develop and test their mental models of tasks and worker behaviors, and then ground those models in worker outputs and majority or gold standard verifications.

A method for indexing a plurality of structures, which are derived from a plurality of externalizations of users' mental models, is provided. The method comprises receiving at least one of the plurality of structures; analyzing the at least one structure according to a predetermined principle of normalization to obtain a plurality of index analysis results in a form of a plurality of tuples comprising a plurality of elements and / or a plurality of relations thereof related to the plurality of structures; and generating an index store according to the index analysis result; wherein each externalized relation indicates each externalized sequence from one of externalized elements to another one of the externalized elements; wherein each relation indicates each sequence from one of a plurality of elements to another one of the plurality of elements.

The invention discloses an evaluation method of multimedia message service user perception and experience QoE for simulating user behavior. The method comprises the steps of firstly setting a multimedia message service QoE evaluation index system including sending and receiving two types of user perception and experience parameters, in terms of service access, service maintenance and service completion, through multimedia message, then adopting a test terminal to simulate the process of sending and receiving multimedia message by the user, respectively gathering and computing key performance indexes KPI of the two types of user perception and experience of the multimedia message service, further computing corresponding key quality indexes KQI of the multimedia message service, adopting a mental model to perform comprehensive operation to KQI, so as to obtain key experience indexes KEI of the corresponding multimedia message service, and then performing comprehensive analysis to the KEI indexes, so as to obtain 5-point system multimedia message service QoE values equivalent to international standard mean opinion score MOS. The method has the advantages that the evaluation parameter standard is objective and practical, the operation steps are simple, the computation complexity is low, and the method is easy to realize, and can simulate the user behavior to obtain objective and fair user perception and experience quality.
