Effective Crowd-Annotation of Participants, Interventions, and Outcomes in the Text of Clinical Trial Reports

2 code implementations Findings of the Association for Computational Linguistics 2020 Markus Zlabinger, Marta Sabou, Sebastian Hofst{\"a}tter, Allan Hanbury

Obtaining such a corpus from crowdworkers, however, has been shown to be ineffective since (i) workers usually lack domain-specific expertise to conduct the task with sufficient quality, and (ii) the standard approach of annotating entire abstracts of trial reports as one task-instance (i. e. HIT) leads to an uneven distribution in task effort.

Interpretable & Time-Budget-Constrained Contextualization for Re-Ranking

1 code implementation4 Feb 2020 Sebastian Hofstätter, Markus Zlabinger, Allan Hanbury

In addition, to gain insight into TK, we perform a clustered query analysis of TK's results, highlighting its strengths and weaknesses on queries with different types of information need and we show how to interpret the cause of ranking differences of two documents by comparing their internal scores.
