We introduce a series of deep stochastic point processes, and contrast them with previous computational, simulation-based approaches.
More specifically, they do not evaluate the systems correctly for situations when there is no answer available and thus agents optimized for these metrics are poor at modelling confidence.
We introduce a simple new performance metric for evaluating question-answering agents that is more representative of practical usage conditions, and optimize for this metric by extending the binary reward structure used in prior work to a ternary reward structure which also rewards an agent for not answering a question rather than giving an incorrect answer.
Bio: Karin Verspoor is a Professor in the School of Computing and Information Systems and Deputy Director of the Health and Biomedical Informatics Centre at the University of Melbourne.
Trained as a computational linguist, Karin’s research primarily focuses on extracting information from clinical texts and the biomedical literature using machine learning methods to enable biological discovery and clinical decision support.

The main goal of the field is to discover which sets of possible phenomena are universal, and which are merely frequent.The NLP group has close associations with the Speech and Hearing and Information Retrieval research groups which carry out research into other areas of computational processing of human language. His personal webpage can be found at https://beckdaniel.and he tweets at https://twitter.com/beck_daniel - Karin Verspoor (University of Melbourne) - Natural Language Processing (NLP) for structuring complex biomedical texts: progress and remaining challenges The NLP community has been focused on methods for identifying and extracting key concepts and relations from highly specialised and terminology-rich texts; these texts have posed a challenge to general NLP tools as well as providing an opportunity to explore the robustness of relation extraction methods to domain-specific applications.In this talk I will present our recent studies with graph kernels and neural methods for relation extraction from the biomedical literature, present empirical work on core supporting tasks such as syntactic analysis of these texts, and discuss open challenges for work in this direction and beyond.Includes platforms for developing and deploying real world language processing applications, most notably GATE, the General Architecture for Text Engineering. For the first part, I will focus on addressing heterogeneous data sources using tools from graph theory and deep learning.Machine Translation: Building applications to translate automatically between human languages, allowing access to the vast amount of information written in foreign languages and easier communication between speakers of different languages. In the second part, I will talk about how to improve decision making from generated texts through Bayesian techniques, using Machine Translation post-editing as a test case.Karin held previous posts as the Scientific Director of Health and Life Sciences at NICTA Victoria Research Laboratory, at the University of Colorado School of Medicine, and Los Alamos National Laboratory.She also spent 5 years in start-ups during the US Tech bubble, where she helped design an early artificial intelligence system.His main research interests include computational social science, information retrieval, and data mining.He holds his Ph D from the School of Computing at Dublin City University (DCU), Ireland.These techniques have applications in areas such as plagiarism and authorship detection and in discovery of hidden content. He is particularly interested in using tools from Machine Learning, Theoretical Computer Science and Statistics to address challenges in NLG that go beyond the usual input-output pipeline.Foundational Topics: Developing applications with human-like capabilities for processing language requires progress in foundational topics in language processing. He obtained a Ph D from The University of Sheffield, United Kingdom, and his thesis on using Gaussian Processes for NLP applications received a Best Thesis Award from the European Association for Machine Translation.
