VIeW (Virtual Information Web) Project at ISX
ISX is currently undertaking several projects aimed at
making Web information more accessible. Our main domain
focus has been ARPA project information webs, but we will
soon be branching out into the education domain to support
the sharing of K-12 educational curricula. This work is
currently supported by the ARPA Intelligent Information
Integration (I3) Initiative.* The project is described in
detail at the URL http://isx.com/~nlehrer/I3/view/view.html.
You can also see the humble beginnings of a VIeW tool kit
from the Intelligent Integration of Information (I3)
Initiative home page at http://isx.com/pub/I3. Go to the I3
Project Lists link.
The VIeW (Virtual Information Web) Project
The purpose of the Virtual Information Web (VIeW) project is
to build tools which aid in the dissemination of ARPA
project information using the World Wide Web.
The World Wide Web is primarily a passive environment. When
a person or organization has some information to share, they
create a web to describe their ideas, products, research,
and hope that others take a look and get interested. There
is a lot of information out there and there are a lot of
people looking for information, yet there are few tools for
querying information beyond indexed searches. Additionally,
the synthesis of information available on the web is a
difficult task due to widely varying presentation styles and
information organization.
The Virtual Information Web Project attempts to address the
some of the issues by abstracting project webs into
structured information which can be viewed and queried in
multiple ways. Additionally, the VIeW project has
experimented with distributed database search over the web.
Unfortunately, this approach is currently sidelined due to
the large amount of support it requires at each individual
site. ARPA sponsored research and technology initiatives
will provide the initial domain and requirements for this
project.
Goals
The goal of the VIeW Project is to enable a virtual
initiative information web where each ARPA contractor
maintains their portion of the web locally in a locally
preferred style, yet the information is made available on an
aggregate level in a globally consistent style. The general
approach is to have ARPA initiative participants develop
local information webs including:
- Project Overviews and Technical Summaries
- Address books, Calendars, Bibliographies
- Administrative data
The goals of the VIeW project are to enable project
information abstraction to support multiple project
information views, project queries, and aggregate initiative
information.
Virtual Information Web Challenges
The Virtual Information Web project faces the following
challenges for acceptance.
Near zero-energy for technologists
The VIeW solution must support a near zero-energy
approach for the technologists.
Perceived Benefit for Technologists
The benefit from ARPA point of view is clear. There must
also be a perceived benefit for a Technologist to use
the VIeW tools. VIeW must illuminate the increased
visibility of their project to both their customer and
other technologists.
Security
VIeW must be secure. Sensitive information must be
guarded. VIeW tools must not open security holes in the
host system.
Usability
VIeW must be easy to use and must not require learning a
large new set of tools. Optimally, VIeW would support
using tools the user is currently familiar with.
VIeW Approach:
The success of the VIeW will depend upon finding the
specific project information and project description
structure underlying the generally unstructured environment
of the Web.
To enable structure discovery, the VIeW approach asks that
technologists re-visit their webs and add annotations which
identify the project information such as project motivation,
overview, goal statements, recent accomplishments, and
unique technology contributions. A web crawler, the VIeW
Maker, will then be responsible for parsing web documents
and creating a structured database on the VIeW server.
Additionally, the VIeW Maker will index project webs using
one of the currently available text indexing schemes to add
keyword search capabilities to the webs.
