 My
current job is as a research specialist for the Alexandria
Digital Library, one of six federally funded digital library
initiatives in the U.S. My areas of research and development
are user needs analysis, user evaluation methodologies
in connection with iterative design of the system, information
retrieval design for networked collections, and information
description methodologies including metadata design and
integration, special services/tools for georeferenced systems
(e.g., gazetteers), and the design of information representation
tools such as thesauri and other terminology systems. The
Alexandria Digital Library supports the use of georeferenced
information - that is, any type of information that is
linked to a location on the surface of the earth. Such
locations can be described spatially with latitude and
longitude coordinates and spatial operations (e.g., contains
and intersects) can be applied for information retrieval.
Another important dimension of the Alexandria collections
is time - the temporal dimension. The challenge is to extend
the technologies and methodologies of text retrieval to
integrate the spatial and temporal dimensions and also
image matching. To build user-centered information systems,
it is also necessary to understand how spatial cognition
works in the context of information creation, description,
retrieval, and use. I work daily with the system designers,
with implementation staff, with information science researchers,
with earth scientists, with university library staff, and
with users of ADL. I participate in the American Society
for Information Science and various metadata and standards
activities.
