Research - Information Integration Lab at Georgia State
Our research group has built a Semantic Facilitator (T)(SM) to display directory objects in a clustered and meaningful way. The prototype includes a user interface, mechanisms to process directory schema create/change requests and extract that directory metadata, a process to extract LDAP schema information and apply an SOM clustering algorithm, and redisplay of the resulting cluster maps to the user interface. The project involves running a clustering algorithm that potentially would cluster large sets of data from multiple directories, so there is also interest in how GRID based resources may permit the Semantic Facilitator (T)(SM) to operate more efficiently by use of distributed resources.
Our research has benefited from an SUN Academic Equipment Grant which has made $111,515 of servers, database machines, and LDAP software and objects. We are also participating in the NSF Middleware Initiative (NMI) Integration Testbed Program which has been funded via a SURA (Southeastern Universities Research Assn.), Educause, and Internet2 consortium to deploy middleware components (directories, GRID technology, best practices and recommendations) into campus infrastructures.
Our work has focused on the metadata of LDAP directories, though we believe our results may be applicable to other domains.
