Active learning for sense annotation
This article describes a real (nonsynthetic) active-learning experiment to obtain supersense annotations for Danish. We compare two instance selection strategies, namely lowest-prediction confidence (MAX), and sampling from the confidence distribution (SAMPLE). We evaluate their performance during the annotation process, across domains for the final resulting system, as well as against in-domai...
متن کاملActive Learning for Video Annotation
In this paper, we present an approach to active learning for video annotation. We use active learning to aide in the semantic labeling of video databases. A software library and simulator have been developed as a tool to investigate and measure the results of active learning. A list of confidence values and nearest neighbor values is maintained for each video segment in the database. A variety ...
متن کاملActive learning: a step towards automating medical concept extraction
OBJECTIVE This paper presents an automatic, active learning-based system for the extraction of medical concepts from clinical free-text reports. Specifically, (1) the contribution of active learning in reducing the annotation effort and (2) the robustness of incremental active learning framework across different selection criteria and data sets are determined. MATERIALS AND METHODS The compar...

متن کاملInvestigating Active Learning for Concept Prerequisite Learning
Concept prerequisite learning focuses on machine learning methods for measuring the prerequisite relation among concepts. With the importance of prerequisites for education, it has recently become a promising research direction. A major obstacle to extracting prerequisites at scale is the lack of large scale labels which will enable effective data driven solutions. We investigate the applicabil...
