| This paper describes a method of visualizing customer expectation as network. Customer expectation is an important factor to succeed in service because the expectation depends on service evaluation. Therefore, for developing service by co-creation, service-provider need the customer expectation. To extract customer expectation, first, we extract co-occurrence network called collective intelligence expectation network from web texts about a target service. From this network, we aggregate the personalized expectation acquired from questionnaire and generate customer expectation network. |
