@ARTICLE{10.21494/ISTE.OP.2019.0380, TITLE={Movie reviews and pirated posts}, AUTHOR={Bruno Hénocque, }, JOURNAL={Information, Organization, Knowledge}, VOLUME={1}, NUMBER={Issue 1}, YEAR={2017}, URL={https://www.openscience.fr/Movie-reviews-and-pirated-posts}, DOI={10.21494/ISTE.OP.2019.0380}, ISSN={2632-6450}, ABSTRACT={The promise of open, free of charge, interactive and democratic spaces is, without any doubt, an important aspect of Web 2.0. The on-line comments or critics of the non-professionals fall within a new phase of capitalism named Contributive Economy by Bernard Stiegler. Nevertheless, the pirated opinions (or pirated comments) are growing up on the e-commercial sites. The problem is important because at least one pirated comment can modify the choice of the internauts. How can we evaluate correctly the comments posted on the movies’ websites, such as Allociné, or on more generic websites, for example, SensCritique (in French: Critical Sense)? This article describes a methodology based on a deep analysis of the on-line comments, followed by the contextual and semantic study in the global context of Web 2.0. The question of a growing importance of the non-human traffic generated by robots is also being studied}}
