This proceedings contains the accepted papers of the SIGIR 2019 Workshop on eCommerce (ECOM19), a full day workshop that took place on Thursday, July 25, 2019 in Paris, France. The workshop was held in conjunction with SIGIR 2019. The purpose of the workshop was to serve as a platform for publication and discussion of Information Retrieval and NLP research and their applications in the domain of eCommerce. eCommerce Information Retrieval has received little attention in the academic literature, yet it is an essential component of some of the largest web sites (such as eBay, Amazon, Airbnb, Alibaba, Taobao, Target, The Home Depot, and others). The SIGIR 2019 Workshop on eCommerce (ECOM19) brought together researchers and practitioners of eCommerce IR to discuss topics unique to it, to set a research agenda going forward, and to examine how to build a data set for research. Our primary motivation as organizers of this workshop was to create a community and act as a forum to discuss interesting research ideas and challenges in the eCommerce domain.
