This paper describes the first evaluation framework for the extractionof Situation Frames - structures describing humanitarianassistance needs - from non-English speech audio, conductedfor the DARPA LORELEI (Low Resource Languagesfor Emergent Incidents) program. Participants in LORELEI hadto process audio from a variety of sources, in non-English languages,and extract the information required to populate SituationFrames describing whether any need is mentioned, thetype of need present and where the need exists. The evaluationwas conducted over a period of 10 days and attracted submissionsfrom 6 teams, each team spanning multiple organizations.Performance was evaluated using precision-recall curves. Theresults are encouraging, with most teams showing some capabilityto detect the type of situation discussed, but more workwill be required to connect needs to specific locations.
