“HYPER GRAPH BASED ONTOLOGY OF MOVIESAuthor: Sandeep Reddy Biddala Date: 2016-07-19 Report no: IIIT/TH/2016/35 Advisor:Navjyoti Singh AbstractCinema, being a newest of art forms, has introduced daunting ontological challenge in accounting for the phantasm of ‘cinematic reality’ and a narrative theorist challenge in accounting for cinematic expressivity or telling. Furthermore, cinema has become entirely digital. There is a need for the com- putable ontology of cinema and in particular narrative computing of cinematic story telling. Research in film theory and even future film making will benefit from building of a semantically searchable archive of digital films based on such formal ontology and narrative computing. The thesis depicts any digital cinema to be a hypergraph of various layers of discretist ontology. In particular, we develop automatic determination of Plot Units of the cinema narrative and depict it as hypergraph. We elaborate on the discrete ontology of cinema as hypergraph and finally suggest prototype of a film archive CinemaScope based on HyperGraph ontology of cinema. We give an initial report on the potential of narrative theory driven graph based representations of movies for narrative analysis and summarization. This is done using automatic generation of Plot Units and determination of affect states for characters in movies. The Plot Units are generated from movie scripts which are textual in nature. The movie scripts are parsed into scenes using a simple grammar. We then use some simple heuristics, rules and techniques to programatically generate Plot Units from these parsed movie scripts. We also present results of character analysis, related events detection and summarization from the generated Plot Units for movies. We use these results to argue that a graph data model for the content of movies could better capture its underlying semantics. We then show that the various graph representations for movies can be made to fit into the HyperGraph ontology. We also present a prototype for a digital film archive called CinemaScope based on HyperGraph ontology for films. Digital film archives in addition to preserving cinema should also accommodate and provide provisions for the computation of its cinematic elements by means of the metadata provided to represent the content in them. The provision for the computation of cinema could lead to various applications like semantic search, automatic genre clustering and classification, special visualization tools and robust comparisons of movies. This prototype has been designed to reduce the content and semantics of a movie to a hypergraph of tags. The prototype is very much in its preliminary stage but could serve as a foundation upon which more robust systems for film archives using HyperGraph ontology could be built upon and used for various research and academic analyses.
