A web-based system providing a service for on demand editing, navigation, and augmenting of audiovisual files comprising a pinner/navigator which automatically creates a .CXU file of an audiovisual project file uploaded to the service, the .CXU file capturing incidence time offsets for textual objects in the file, the pinner/navigator comprising an editor providing a graphical user interface enabling users to edit the audiovisual project file by modifying textual objects, pinning beginning and ending boundaries for textual objects of interest, and navigating the file by selecting textual objects, the pinner/navigator automatically outputting an edited project file per user edits; a service API wrapper providing an interface for accessing one or more recognition services which automatically generate semantic metadata comprising recognized objects for the uploaded audiovisual file, a semantics calculator operating on the recognized objects using a semantic calculus, a semantics editor, and an audiovisual file encoder/decoder. |

1. A web-based system for providing a service for on demand editing, navigation, and augmenting of audiovisual files comprising one or more user computers configured with a web browser and one or more service servers, users accessing the service servers via the web browser over the Internet, the service servers comprising one or more subsystems, each subsystem comprising machine executable code embodied on a non-transitory computer-readable medium enabling functionalities as defined:
a pinner/navigator which automatically creates a .CXU file of an audiovisual project file uploaded to the service, the .CXU file capturing incidence time offsets for textual objects in the file, the pinner/navigator comprising an editor providing a graphical user interface enabling users to edit the audiovisual project file by modifying textual objects, pinning beginning and ending boundaries for textual objects of interest, and navigating the file by selecting textual objects, the pinner/navigator automatically outputting an edited project file per users' edits; a service API wrapper providing an interface for accessing one or more recognition services which automatically generate semantic metadata for the user-uploaded audiovisual project file, the semantic metadata comprising recognized objects and their semantic interpretations, the recognized objects being associated with their respective incidence time offset relative to the start time zero of the source audiovisual file of the project file, recognized object names becoming a part of a working ontology for the project file; a semantic Calculator operating on recognized objects using a semantic calculus in one or more operations from the group of addition, subtraction, division, equivalence, and transitive inference wherein an external ontology is matched to the working ontology to transitively apply new names to recognized object names, a semantics editor providing a graphical user interface allowing users to access recognized objects, input additional recognition, recognized objects stored in a recognized objects data store comprising project identifiers, recognition specifics, an audiovisual file encoder/decoder which incorporates and decodes the semantic metadata generated for the uploaded source audiovisual project file, and a project controller comprising a cloud-enabled multi-processor asynchronous processing for managing operations comprising user security and initiating service operations as required to accomplish user requests. |
