|One can view
these technology layers symbolically as shown on this slide.
axis represents semantic content, or the degree to which data can be
abstracted to represent information centered around specific arguments being
postulated. The horizontal axis represents the continuum of the data space
which provides the necessary evidence to support or refute specific argument
|Data is gathered
from events occurring in the real world as measured by sensors (to include
humans) and as available in various open source including the World Wide Web
and classified databases. These data contain inherent semantic value that is
largely derived from the language which is used to describe them. I have termed this the “index space”. You might think of “key words” as one form
of “index” derived from an understanding of the meaning of symbols used in
the English language as represented in a word document . At a higher level of abstraction, you
might define the “index space” using
“concepts”. I’ve represented one
document as the large white bar in the information space and shown it’s key
words linked into the index space.
|Above the Index
Space are evidence models which are derived from intent models and argument
models for the hypothesis under consideration that enable the association of
(“index”) evidence to arguments being
postulated. These models help both to
drive the search for supporting evidence, and provide the metric for scoring
the value of new evidence found. A
document that has high semantic content has more keywords that are included
in the index space than one with lower semantic content and thus is easier to
find during search. In general, documents with low semantic content require
more knowledge and tailoring of search terms in order to guarantee successful
retrieval ( template match).
|The index space
provides the basic evidence layer that can be mapped onto projections of the
arguments through the use of intent models or other such constructs. These evidence data then are the basis for
supporting or refuting arguments postulated and being reasoned.
|I will now delve
deeper into the technologies of each layer.
