Oohay: Visualizing the Web

Research Goal

DLI-1
The Digital Library project phase 1 at University of Arizona was one of the original NSF-funded Digital Library Initiative (DLI) projects. The project aimed to develop techniques to enhance information retrieval of large digital collections and to support semantic interoperability across subject domains.

OOHAY: Visualizing the Web (DLI-2)
The Object Oriented Hierarchical Automatic Yellow Page (OOHAY) project is part of the Phase 2 Digital Library Initiative project at the University of Arizona, which is funded by NSF Digital Library Initiative-2. The goal of our digital library project is to develop techniques and methodologies for automatically analyzing and visualizing large collections of unstructured documents. The project will integrate system and human-generated classification systems and will create a high-performance digital library classification system (i.e., the OOHAY system).
