Embodiment Construction

[0035] figure 1 A classification unit 10 implementing the solution according to the invention is described. In order to detect and classify the content and structure of the file, the parsing unit 11 applies at least one of a set of configuration files or mapping scripts 12 to a file 13, such as a data file, a metadata file or a media file, in order to generate a time domain and / or or the internal representation of a file in a domain. The content of the input file 13 is mapped to an internal representation containing only the information necessary to classify the file 13 in the temporal and / or structural domains. Then, the semantic analysis unit 14 generates a structural classification 15 and a temporal classification 16 of the content of the input document. Internal representations are generated by eg simple text mapping, visual content to text mapping (OCR), data extraction from binary files, etc. The mapping script 12 is responsible for mapping the syntax of the input fil...

Abstract

A method for classification of a file (13) or a part of a file (13) and an apparatus (10) configured to perform such classification are described. The file (13) is retrieved (20) via a first input (17), whereas via a second input (18) a transformation script (12) for the file (13) is obtained (21), the transformation script (12) enabling mapping of content of the file (13) to a representation of the file (13) only containing information suitable for classification of the file (13). A syntax analysis unit (11) performs a syntax analysis (22) on the file (13) or on the part of the file (13) using the transformation script (12) to generate the representation of the file (13). This representation of the file (13) is provided to a semantic analysis unit (14), which performs a semantic analysis (23) on the representation of the file (13). A structural classification (15) and / or a temporal classification (16) resulting from the semantic analysis (23) are made available via an output (19).

Description

technical field [0001] The invention relates to a method and a device for classification of documents or parts of documents. More specifically, methods and apparatus are described that allow classification of documents or parts of documents in the temporal and structural domains. Background technique [0002] During the generation of digital media content, various files are generated, such as content media files and metadata files. These documents typically have multiple temporal and / or structural relationships. [0003] An example of a file with only structural information is a movie script. Such movie scripts contain structural information about the movie's scenes and shot sequences, but generally no temporal information is available. In contrast, recorded camera take media files contain only temporal references, ie information when the take has been taken, but typically no metadata with structural references available. This information can be provided eg as time of da...
