1 code implementation27 Mar 2023 Fajar J. Ekaputra, Majlinda Llugiqi, Marta Sabou, Andreas Ekelhart, Heiko Paulheim, Anna Breit, Artem Revenko, Laura Waltersdorfer, Kheir Eddine Farfar, Sören Auer

In line with the general trend in artificial intelligence research to create intelligent systems that combine learning and symbolic components, a new sub-area has emerged that focuses on combining machine learning (ML) components with techniques developed by the Semantic Web (SW) community - Semantic Web Machine Learning (SWeML for short).

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.

Leveraging the Wisdom of the Crowds for the Acquisition of Multilingual Language Resources

no code implementations LREC 2012 Arno Scharl, Marta Sabou, Stefan Gindl, Walter Rafelsberger, Albert Weichselbraun

We describe the goals and structure of the game, the underlying application framework, the sentiment lexicons gathered through crowdsourcing, as well as a novel approach to automatically extend the lexicons by means of a bootstrapping process.
