It is being created in the context of a project that is developing meeting browsing technology and will eventually be released publicly. Some of the meetings it contains are naturally occurring, and some are elicited, particularly using a scenario in which the participants play different roles in a design team, taking a design project from kick-off to completion over the course of a day. The corpus is being recorded using a wide range of devices including close-talking and far-field microphones, individual and room-view video cameras, projection, a whiteboard, and individual pens, all of which produce output signals that are synchronized with each other. It is also being hand-annotated for many different phenomena, including orthographic transcription, discourse properties such as named entities and dialogue acts, summaries, emotions, and some head and hand gestures. We describe the data set, including the rationale behind using elicited material, and explain how the material is being recorded, transcribed and annotated.}, booktitle = {Proceedings of the Second International Conference on Machine Learning for Multimodal Interaction}, pages = {28–39}, numpages = {12}, location = {Edinburgh, UK}, series = {MLMI'05} } """ _URL = "https://groups.inf.ed.ac.uk/ami/corpus/" _DL_URL_ANNOTATIONS = "http://groups.inf.ed.ac.uk/ami/AMICorpusAnnotations/ami_public_manual_1.6.2.zip" _DL_SAMPLE_FORMAT = "https://groups.inf.ed.ac.uk/ami/AMICorpusMirror//amicorpus/{}/audio/{}" _SPEAKERS = ["A", "B", "C", "D", "E"] # Commented out samples don't seem to exist _TRAIN_SAMPLE_IDS = [ "ES2002a", "ES2002b", "ES2002c", "ES2002d", "ES2003a", "ES2003b", "ES2003c", "ES2003d", "ES2005a", "ES2005b", "ES2005c", "ES2005d", "ES2006a", "ES2006b", "ES2006c", "ES2006d", "ES2007a", "ES2007b", "ES2007c", "ES2007d", "ES2008a", "ES2008b", "ES2008c", "ES2008d", "ES2009a", "ES2009b", "ES2009c", "ES2009d", "ES2010a", "ES2010b", "ES2010c", "ES2010d", "ES2012a", "ES2012b", "ES2012c", "ES2012d", "ES2013a", "ES2013b", "ES2013c", "ES2013d", "ES2014a", "ES2014b", "ES2014c", "ES2014d", "ES2015a", "ES2015b", "ES2015c", "ES2015d", "ES2016a", "ES2016b", "ES2016c", "ES2016d", "IS1000a", "IS1000b", "IS1000c", "IS1000d", "IS1001a", "IS1001b", "IS1001c", "IS1001d", "IS1002b", "IS1002c", "IS1002d", "IS1003a", "IS1003b", "IS1003c", "IS1003d", "IS1004a", "IS1004b", "IS1004c", "IS1004d", "IS1005a", "IS1005b", "IS1005c", "IS1006a", "IS1006b", "IS1006c", "IS1006d", "IS1007a", "IS1007b", "IS1007c", "IS1007d", "TS3005a", "TS3005b", "TS3005c", "TS3005d", "TS3006a", "TS3006b", "TS3006c", "TS3006d", "TS3007a", "TS3007b", "TS3007c", "TS3007d", "TS3008a", "TS3008b", "TS3008c", "TS3008d", "TS3009a", "TS3009b", "TS3009c", "TS3009d", "TS3010a", "TS3010b", "TS3010c", "TS3010d", "TS3011a", "TS3011b", "TS3011c", "TS3011d", "TS3012a", "TS3012b", "TS3012c", "TS3012d", "EN2001a", "EN2001b", "EN2001d", "EN2001e", "EN2003a", "EN2004a", "EN2005a", "EN2006a", "EN2006b", "EN2009b", "EN2009c", "EN2009d", "IN1001", "IN1002", "IN1005", "IN1007", "IN1008", "IN1009", "IN1012", "IN1013", "IN1014", "IN1016", ] _VALIDATION_SAMPLE_IDS = [ "ES2011a", "ES2011b", "ES2011c", "ES2011d", "IS1008a", "IS1008b", "IS1008c", "IS1008d", "TS3004a", "TS3004b", "TS3004c", "TS3004d", "IB4001", "IB4002", "IB4003", "IB4004", "IB4010", "IB4011", ] _EVAL_SAMPLE_IDS = [ "ES2004a", "ES2004b", "ES2004c", "ES2004d", "IS1009a", "IS1009b", "IS1009c", "IS1009d", "TS3003a", "TS3003b", "TS3003c", "TS3003d", "EN2002a", "EN2002b", "EN2002c", "EN2002d", ] _DESCRIPTION = """\ The AMI Meeting Corpus consists of 100 hours of meeting recordings.
