Semantic Role Labeling (SRL) for tweets is a meaningful task that can benefit a wide range of applications such as finegrained information extraction and retrieval from tweets. One main challenge of the task is the lack of annotated tweets, which is required to train a statistical model. We introduce self-training to SRL, leveraging abundant unlabeled tweets to alleviate its depending on annotated tweets. A novel strategy of tweet selection is presented, ensuring the chosen tweets are both… CONTINUE READING
