The accelerated iteration of information technology has formed a new mode of hosted communication. The mode is centered on human and virtual digital human, and integrates multiple modal signals such as video, sound, and text. The boundary between professional and general hosted communication has gradually become blurred. The content homogenization and weakening of communication penetration are becoming more and more prominent. Therefore, this paper studies the methods to improve the effectiveness of hosted communication. Specifically, based on the theory of computational social science, this study firstly proposes the paradigm of computational hosted communication. The multimodal selfconsistent presentation of hosted communication is the key to realize the effective coordination of multimodal information. Multitemporal and multiscale accurate analysis and effective measurement of hosted communication effectiveness are important supports. Multimodal information fusion methods are studied to realize the differentiation and finegrained perception of communication content and effectiveness. This research provides quantitative theoretical methods, frameworks, and guiding principles for host communication in the era of digital intelligence.
