The SUMMA Platform: Scalable Understanding of Multilingual Media (2018)

Abstract: We present the latest version of the SUMMA platform, an open-source software platform for monitoring and interpreting multi-lingual media, from written news published on the internet to live media broadcasts via satellite or internet streaming.

## introduction the summa platform is a highly scalable opensource infrastructure for monitoring and interpreting news streams in multiple languages, 1 and a variety of media formats, from written text published on the internet to live tv broadcasts via satellite. three use cases drive the project. ## architecture the design of the summa platform is shown in fig. 1 . incoming media streams are downloaded and/or recorded, depending on the source. audio is automatically transcribed, and non-english material is machine-translated into english. the resulting text-based news items are then processed with downstream nlp modules: topic detection; named entity recognition and linking, and extraction of relations between named entities to build up a knowledge base of "facts" (i.e., factual claims made in news reporting); and document clustering and multi-document cluster summarization. news items, mentions of named entities, etc., are stored in a central database that can be accessed by users via web-browser-based user interfaces, or by programs via programmatic interfaces (apis).
