Topic: Graphing Large Family Trees

Derek is playing a key role in the OnePageGenealogy project. The goal of OPG is to devise algorithms for graphing large family trees, possibly comprised of thousands of ancestors and descendants, on a poster‐sized sheet of paper. Derek has done some excellent work on making the software interactive so that a genealogist can easily direct the creation of a large pedigree chart. The software has successfully charted pedigree charts going back 150 generations.

Advisor: David Embley
Topic: Conceptual Modeling

Jeff worked on the automatic layout for conceptual model diagrams. He selected some graph layout software on the web and adapted it for an ontology editor developed at BYU.  The system works by reverse‐ engineering an XML‐Schema document into a conceptual model and then displaying it for further use.

Topic: Active Learning

Peter McClanahan has been working on the Active Learning for Annotation (ALFA) project in the NLP lab. ALFA will make labeled text resources available in languages where labeled corpora are scarce or non‐existent. Furthermore, ALFA enables the training of models on these new text resources. Active learning is an approach to classification that uses automatically learned models to annotate easy cases and automatically requests the assistance of a human annotator to annotate the tough cases and to provide further guidance where necessary. The project has also involved the creation of new active learning techniques and new ways to evaluate the efficacy of those techniques in reducing annotation
cost. Peter has played a critical role in running these experiments.
