A Case Study for Predicting in-Hospital Mortality by Utilizing the Hyperbolic Embedding of ICD-9 Medical Ontology
Cao, Jiazhen
In-hospital mortality prediction is signi cant for evaluating a patient's
severity of illness ahead of the time. The outcome of the evaluation can
help physicians to identify which patient is at risk and needs immediate
care, it can further increase the e ciency of use of medical resources.
In this study, I proposed a method that is similar with the one in
our Electronic Health Records (EHRs) research at the CBL Lab and
utilized the hyperbolic embedding of ICD-9 medical ontology for the
prediction model. The results outperformed the benchmark prediction
model and demonstrated that the hyperbolic embedding on ICD-9 is
more e ective than other graph embedding methods.

Usability and the evolving library website
Beseda, Addie Marie
The academic library website presents many complex usability issues, and
most are affected by the ever-changing nature of digjtal information. This
thesis explores these issues with the aid of usability testing on the University
of Oregon Libraries website. Undergraduates performed tasks that reflect
real library usage; the problems they encountered are summarized based on
the usability measures of effectiveness, efficiency, and satisfaction. The
study found that although students were able to effectively use the UO
Libraries website to conwlete tasks, they did so inefficiently, with many
missteps before reaching completion. Similarly, although students were able
to find the information they needed on the website, they indicated that they
preferred search engines over libraries for research purposes. These results
serve as a starting point for discussion of the relationship between the library
website and the search engine, the necessity of background knowledge in
information gathering for competent website use, and a strategy for making
the Libraries website into a tool students prefer.
