TypEx : a type based approach to XML stream querying [PDF]
, 2003 We consider the topic of query evaluation over semistructured information streams, and XML data streams in particular. Streaming evaluation methods are necessarily eventdriven, which is in tension with high-level query models; in general, the more ...

Exam‐level analysis of lecture capture viewing and student exam performance
FEBS Open Bio, EarlyView.This study asks how lecture capture relates to exam performance in biology courses with three noncumulative exams. Mixed‐effects modeling separated between‐students from within‐student effects on exam %. Students who watched more recordings earned higher grades, but viewing spikes above a student's own mean, consistent with cramming, predicted small ...

A query language for analyzing networks
Proceedings of the 18th ACM conference on Information and knowledge management, 2009 With more and more large networks becoming available, mining and querying such networks are increasingly important tasks which are not being supported by database models and querying languages. This paper wants to alleviate this situation by proposing a data model and a query language for facilitating the analysis of networks.
