<p>"In the last decade, the technology for biomedical literature annotation made a significant progress in terms of accuracy and speed. Now, some annotation systems claim that they have reached a production level. However, there still remain critical issues which we believe hinder further progress of the community. Among them, a relatively well known issue is "interoperability" of annotation resources. We also recognize that the community is missing a general solution for "storage infrastructure". The talk will present the PubAnnotation project which aims at addressing these two issues. In the end, a new model for "sustainable shared tasks", which is implemented on PubAnnotation, will be introduced as well."</p>
