TL;DR: By constructing a game that regards each stage as a player, cooperative game theory with network data envelopment analysis (DEA) is integrated with network DEA to explore the payoff allocation problem in a three-stage system and indicates that the game among stages in aThree-Stage system is superadditive.

TL;DR: A theoretical model develops a theoretical model to explore the influences of material and professional motivation on free information sharing and the contingent roles of professional expertise and online expertise and indicates that in addition to material motivation, professional motivation also plays a primary role in inducing physicians to share free information.

TL;DR: A stochastic DEA model considering undesirable outputs with weak disposability which not only can deal with the existence of random errors in the collected data, but also depicts the production rules uncovered byWeak disposability of the undesirable outputs is proposed.

TL;DR: Utility analysis is introduced to the link prediction method by considering that individual preferences are the main reason behind the decision to form links, and meanwhile it also focuses on the meeting process that is a latent variable during the process of forming links.

TL;DR: The proposed extended TODIM method to rank products through online reviews uses the IF (intuitionistic fuzzy) based sentiment word framework and corresponding computation rules, where intuitionistic fuzzy set (IFS) is used to describe sentiment orientations and emotional intensity.
