Task: 2nd edition of the Chemotherapy Treatment Event Extraction from the Clinical Narrative (text mining task) This is the 2nd edition of the shared task whose goal is the extraction of a timeline of chemotherapy treatment for each patient given all the available Electronic Health Records (EHR) notes of that patient. The notes range the entire spectrum -- primary care provider, oncology, discharge summaries, emergency department, pathology, radiology, etc. Success in completing this task will provide previously unavailable tools for extracting timelines for contextualizing cancer treatment. The 2nd edition of the shared task builds on the very successful 2024 Chemotherapy Treatment Timelines Extraction Shared Task. Are state-of-the-art Large Language Models (LLMs) and Artificial Intelligence (AI) able to solve this critical task? As these tasks involve cancer patient data, each participating team will need to complete a Data Use Agreement with the University of Pittsburgh. Teams are encouraged to register and start this process early to allow for sufficient time for agreements to be approved. The process is the same as for the 1st edition of the shared task. The shared task is organized in two sub-tasks, each aiming to spur innovation in the field. Subtask 1: Gold chemotherapy events (EVENTS) and time expressions (TIMEXs) are provided. The goal is to predict the temporal relations between them, then produce the final patient-level timelines which involves deduplicating and resolving conflicts in the pairwise temporal relations if pairwise temporal relations are chosen to use as the intermediate representation. Gold event attributes, including modality, the relation of the event to the document creation time (DocTimeRel), and time expression normalizations generated by TimeNorm (https://github.com/clulab/timenorm<https://urldefense.com/v3/__https:/github.com/clulab/timenorm__;!!NZvER7FxgEiBAiR_!vc_upkV8-30pXrSLnKo7OjVqQu_p5Tr9eJnUbuh0FjZO_37OOmQaGSwmhoRacRapR9LSTqhkdUfyWmF5B8yxwVdHe_hwnIB1_yKIQO9996IThuGt$>) are also provided. Subtask 2: In this subtask, ONLY patient notes are given, participants are expected to build an end-to-end system for chemotherapy timeline extraction. Data: EHR documents of ~62,000 patients with breast and ovarian cancer and ~16,000 patients with melanoma split into LABELLED and UNLABELLED data. Important dates: Due dates listed below are end of each day (23:59:59), Anywhere on Earth (AoE: UTC-12).
