NLP for medical informatics + question answering

We have 2 speakers lined up for this event: Phil Gooch and Danica Damljanovic. As usual we'll meet at Fizzback's offices on the Strand at 18:30 for the talks then adjourn to a local pub afterwards. Hope to see you there!

Details as follows:

Automating the formalization of clinical guidelines using information extraction: an overview of recent lexical approaches, Phil Gooch (City University)

Formalizing guideline text into a computable model, and linking clinical terms and recommendations in clinical guidelines to concepts in the electronic patient record (EHR) is difficult as, typically, both the guideline text and EHR content may be ambiguous, inconsistent and make use of implicit and background medical knowledge. How can lexical-based IE approaches help to automate this task? In this presentation, various design patterns are discussed and some tools presented.

Question-Answering over Linked Data ,Danica Damljanovic (Sheffield University)

The availability and growth of the Linked Open Data cloud made exploiting the rich semantics easily accessible but also challenging mainly due to its scale. In this talk I will discuss challenges for building a Question-Answering system that uses these data as the main source for finding the answer. I will introduce the FREyA system which combines syntactic parsing with the semantic annotation in order to correctly interpret the question, and involves the user into dialog if necessary. Through the dialog, FREyA allows the user to validate or change the semantic meaning of each word in the question - the user's input is used to train the system and improve its performance over time.
