Film Copyright Value Assessment Adapted From Online Novels

With the development of the Internet and information technology,entertainment methods are showing the pursuit of diversification and experiential development,and the entertainment product in the form of text-web novels-is also developing toward a cross-disciplinary and cross-media trend.This form of development with text as the core content has derived a value chain,which in turn has brought huge economic revenue generation to industries such as culture and entertainment.The interaction between movies and online novels is particularly significant.Adaptations of online novels into movies are usually limited by the current legal environment,chapter and length,and require necessary changes,but the adaptations may result in movies infringing on online novels under the influence of various factors.For example,the court ruled that movie A infringed web novelist B’s right to protect the integrity of his work,and the infringing party was required to compensate web novel writer B a total of RMB 50,000.In this case,the phenomenon of vague definition of copyright and low compensation amount appeared,which did not fully play the role of copyright protection.In this paper,we explore the value of copyright of online novels and find that the value of certain rights of copyright of online novels can be reflected from the value of copyright of derivative products,but there is still a lack of research on the assessment of the value of such infringement.This paper firstly compares the research background and relevant domestic and foreign literature,and formulates the idea of assessing the value of copyright of movies adapted from online novels based on the perspective of infringement damages,which is mainly calculated and summarized in three parts based on the Copyright Law stipulating that the calculation of infringement damages can be calculated from the revenue earned by the infringer.Firstly,the feasibility of the revenue method as a movie copyright value assessment method is analyzed,which focuses on the reliability of predicting movie box office revenues with an extreme random tree model;then,the hierarchical analysis method is used to obtain the revenue stratification rate and calculate the influence weights brought by the value of copyright of online novels to movie box office revenues;finally,the hierarchical analysis method is used to calculate the influence weights of each right of copyright of online novels.Based on this idea,we construct a model for evaluating the value of movie copyrights adapted from web novels based on the perspective of infringement compensation,and finally,the case of infringement of web novel writer B by movie A is used as a validation,and the infringement value of the case is calculated as 2.305 million yuan.In this paper,we find that machine learning algorithms are highly feasible as a tool for movie box office revenue prediction,and there is much room for improvement.A major difficulty in the current adaptation of online novels into movies is that online novels as scripts have certain conflicts with the current social environment,and if there is more communication between the two when they cooperate across fields,it may lead to better works.Since the current Copyright Law does not have a precise calculation method for damages for infringement of the right to protect the integrity of a work,this paper believes that it can be used as a third-party reference basis for the court or the infringer to define infringement damages after assessing the infringement value by means of asset appraisal.
