Project Topic Proposal: iFixit Recommender System
28/12/11 18:11 Filed in: 481
The ifixit Web site offers instructions for repairs of all kinds of devices, and has recently been expanded to allow the submission of user-generated instructions. The company, co-funded by a CSC alumnus, is interested in adding a recommendation facility that would offer user suggestions such as other devices or repairs they may be interested in, or parts and tools that are suitable for the repair. They currently have recommendations for the latter, but they are not very sophisticated.

The goal of this project is to provide educational resources for a course similar to this one, but intended for participants without a strong computer background.
Project Topic Proposal: Visualization of Ontologies and RDF Graphs
27/12/11 11:46 Filed in: 481
The underlying data structures for ontologies and RDF (Resource Data Framework) structures are graphs. While graphs in principle are well suited for visualization purposes, there are several challenges for these particular structures. Ontologies frequently have a multitude of relationships (links in the graph), and it is impractical to display all of them simultaneously. RDF graphs frequently are huge, and can’t be displayed in their entirety. In both cases, however, there are underlying principles that humans intuitively utilize to arrange the nodes in both a visually pleasing and easy to comprehend manner (although it may be very difficult or impossible to achieve both). The objective of this project is to examine existing visualization methods for ontologies and RDF graph, and identify their advantages and shortcomings. On the other side, there are packages available for displaying generic graphs. Our hope is that a combination of insights from the existing visualization tools with advanced graph display packages, together with heuristics that reflect organizational principles for ontologies and RDF graphs will result in better visualization tools. Ideally, a prototype of such an ontology visualization tool would be integrated with the Protégé ontology development environment.
Project Topic Discussions

I just realized that we could use the Comments feature of these pages for additional project proposals and discussions of the topic I mentioned yesterday. So I’m going to create a new entry for each topic. Please add a comment if the topic sounds interesting to you (this does not constitute a commitment to actually select it), or if you have questions.
I’ll also create another entry for additional project ideas. If you have one, add it there as a comment.
