MMIF Summarizer

The Summarizer is a MMIF consumer that creates a JSON summary from a MMIF file. It makes some simplifying assumptions, including:

• There is one video in the MMIF documents list. All start and end properties are pointing to that video.

• The time unit is assumed to be milliseconds.

The summarizer is accessible via the mmif command line script. To run the summarizer over a MMIF file and write the JSON summary to OUTFILE:

mmif summarize -i INFILE -o OUTFILE

In all cases, the summarizer summarizes only the information that is there, it does not fix any mistakes and in general it does not add any information that is not explicitly or implicitly in the MMIF file. In rare cases some information is added, for example if an ASR tool does not group tokens in sentence-like objects then the summarizer will do that, but then only by creating token groups of the same length.

The summary includes the MMIF version, the list of documents, a summary of the metadata of all views (identifier, CLAMS app, timestamp, total number of annotations and number of annotations per type, it does not show parameters and application configuration), time frames, transcript, captions and entities.
