Probing the Cosmic Star-Formation History Revealed by Blind Searches for Far-Infrared Emission Line Galaxies

Using blind line searches to understand the cosmic star-formation history is one of the strategies that should be pursued by ALMA and next-generation mm/submm single-dish telescopes.  Before moving into such a new era, it is essential to develop a method to efficiently detect faint line-emitting sources whilst considering the completeness of source detection and contamination by false detections.  In this presentation, we summarize how we tried to tackle the science question.
