Relevant evidence acquisition and appraisal using knowledge-intensive queries

Muhammad Afzal, Sungyoung Lee
2016 2016 18th International Conference on Advanced Communication Technology (ICACT)  
In healthcare domain, the clinical researchers and physicians are even more interested to find quality information to use as a clinical evidence in decision making.  ...  The first challenge is to automatically reformulate the user query into a knowledge-intensive query in order to acquire articles that are relevant to user needs.  ...  INTRODUCTION Evidence-based systems have long been used in clinical domain for clinical practice as a support to the clinicians in order to make better clinical decisions.  ...

Knowledge Enhanced Representations to Reduce the Semantic Gap in Clinical Decision Support

Stefano Marchesin
2019 BCS-IRSG Symposium on Future Directions in Information Access  
The semantic gap between queries and documents is a longstanding problem in Information Retrieval (IR), and it poses a critical challenge for medical IR due to the large presence in the medical language  ...  Two main lines of work have emerged in the past years to tackle this issue: (i) the use of external knowledge resources to enhance query and document bag-of-words representations; and (ii) the use of semantic  ...  Acknowledgements The work was supported by the ExaMode project, as part of the European Union H2020 program under Grant Agreement no. 825292.  ...

Implicit Negative Feedback in Clinical Information Retrieval

Lorenz Kuhn, Carsten Eickhoff
2016 Swiss Medical Informatics  
Our experimental results are based on data collected in the course of the TREC Clinical Decision Support Track and show consistent improvements compared to state-of-the-art methods.  ...  For queries that make excessive use of negations, we were able to achieve up to 300% relative improvement in early precision.  ...  State-of-the-art retrieval models applied to clinical decision-support settings rely on full-text indices of biomedical literature and use the textual content of the patient record to construct queries  ...

Revisiting Medical Entity Recognition through the Guidelines of the Aurora Initiative

Praveen Kumar, Sabah Mohammed, Arnold Kim, Jinan Fiaidhi
2016 International Journal of Bio-Science and Bio-Technology  
This research focused to produce a prototype system which allows the user to input their queries about a clinical text in a syntax free language which will be reformulate into DSL format in background.  ...  The reformulated query then matches against the rules defined by using the DSL to get the matched rule-type. The DSL is created using Xtext framework specifically to create NER rules easily.  ...  It was originally designed for decision support applications in the domain of radiology reports of the chest, and was extended to other domains, such as mammography and discharge summaries later.  ...

Robust diagnostic classification via Q-learning

Victor Ardulov, Victor R. Martinez, Krishna Somandepalli, Shuting Zheng, Emma Salzman, Catherine Lord, Somer Bishop, Shrikanth Narayanan
2021 Scientific Reports  
AbstractMachine learning (ML) models have demonstrated the power of utilizing clinical instruments to provide tools for domain experts in gaining additional insights toward complex clinical diagnoses.  ...  This work formulates diagnostic classification as a decision-making process and utilizes Q-learning to build classifiers that meet the aforementioned desired criteria.  ...  Acknowledgements This research was supported by the Simons Foundation and National Institutes of Health (NICHD Grant No. 1R01HD093012-01).  ...

Do Users Benefit from Controlled Vocabularies in Search Interfaces?

Ying-Hsang Liu, Paul Thomas, Jan-Felix Schmakeit, Tom Gedeon
2012 European Workshop on Human-Computer Interaction and Information Retrieval  
These vocabularies are expensive to build and use, however, and seem to be useful mostly for domain experts.  ...  Search providers in domains from medicine to news have long labelled documents with controlled vocabularies, to help users explore their collections.  ...  the decision-making process in query reformulation; particularly for difficult search topics.  ...
