We introduce the specification and goals of the task, describe the data sets and evaluation methods, and present a general overview of the 19 systems that have contributed to the task, providing a comparative description and results. 1 Introduction In the few last years there has been an increasing interest in shallow semantic parsing of natural language, which is becoming an important component in all kind of NLP applications. As a particular case, Semantic Role Labeling (SRL) is currently a welldefined task with a substantial body of work and comparative evaluation.
