Below we list many of the projects underway in the WUME Lab. If you are
a student and would like to participate in one of these, please contact
Efficient and Effective
Search Services Over Archival Webs.
In this NSF-funded project we consider how to mine and
search archival content. This is in collaboration with NYU Polytechnic
and the Internet Archive.
Contextual Link Analysis.
In this NSF-funded project we consider the context in which a link is
found. Such contexts can be incorporated into the link analysis to
improve ranking quality.
Understanding and Enhancing Queries.
This NSF-funded project considers topic distributions in queries and results,
and exploits the query and results bipartite graph to provide related queries,
related pages, and suggested queries for websites.
EDIFY Disruption and Delay Tolerant
Networking. In this DARPA-supported project, we design a
store-and-forward messaging architecture that sits on top of an existing
network infrastructure that is tolerant of delays, disruptions, and node
Mozilla Prefetching. We have implemented history and
content-based prefetching systems and have added them to the open
source Mozilla browser.
DNSflow. DNSflow captures DNS packets and logs contents and
timestamps for offline analysis.
HTTPflow. Based on tcpflow, HTTPflow captures port 80 (Web)
traffic and writes the headers and timestamps to a log for offline
analysis. Using this tool we can capture much more detail (especially
with respect to caching) than is recorded by Web servers or proxy
caches. It also does not require any changes to the clients or servers.
LEAP: Lehigh Evaluation Architecture for Proxies. In this
project, we implemented a Simultaneous Proxy Evaluation (SPE) prototype.
Apache Prefetching Hints. We have modified Apache to
generate HTTP prefetching hints as supported by the open
source Mozilla and Firefox browsers.
Analysis. This research focuses primarily on measuring,
documenting and understanding the network, which should allow for
future improvements to the network architecture, and to extensions of
the network functionality.
