Supporting Humans in the Information Extraction Loop: An In-depth Study of the Practices, Limitations, and Opportunities

Through our interviews and follow-up analysis, we provide a fine-grained characterization of information extraction workflows using a task-based model, identify related challenges faced by the human-in-the-loop, and propose design guidelines for addressing these challenges. We now discuss a few of the implications of the task model and our proposed design considerations for developing IE tools.
