Open AccessThymic Atrophy and Immune Dysregulation in Infants with Complex Congenital Heart Disease
Congenital heart disease (CHD) is the most common birth defect, and up to 50% of infants with CHD require cardiovascular surgery early in life. Current clinical practice often involves thymus resection during ...

Feedback Loops and Complex Dynamics of Harmful Speech in Online Discussions
Harmful and toxic speech contribute to an unwelcoming online environment that suppresses participation and conversation. Efforts have focused on detecting and mitigating harmful speech; however, the mechanisms...

Incident-Driven Machine Translation and Name Tagging for Low-resource Languages
We describe novel approaches to tackling the problem of natural language processing for low-resource languages. The approaches are embodied in systems for name tagging and machine translation (MT) that we cons...

Applications of Weighted Automata in Natural Language Processing
We explain why weighted automata are an attractive knowledge representation for natural language problems. We first trace the close historical ties between the two fields, then present two complex real-world p...

Backward and Forward Bisimulation Minimisation of Tree Automata
We improve an existing bisimulation minimisation algorithm for tree automata by introducing backward and forward bisimulations and develo** minimisation algorithms for them. Minimisation via forward bisimula...

Bisimulation Minimisation for Weighted Tree Automata
We generalise existing forward and backward bisimulation minimisation algorithms for tree automata to weighted tree automata. The obtained algorithms work for all semirings and retain the time complexity of th...

Tiburon: A Weighted Tree Automata Toolkit
The availability of weighted finite-state string automata toolkits made possible great advances in natural language processing. However, recent advances in syntax-based NLP model design are unsuitable for thes...
