Expert System Releases Live Semantic Index of Obama Administration's Recovery.gov and Data.gov Sites

SAN JOSE, CA, Jun 16 (MARKET WIRE) --
SEMANTIC TECHNOLOGY CONFERENCE -- Expert System, leading provider of
semantic software that searches, discovers, classifies and interprets
unstructured text information, today announces it has semantically
indexed all information on Recovery.gov and Data.gov -- the two Obama
Administration Web sites created for public accountability and openness.

The semantic indexing of Recovery.gov and Data.gov allows citizen users to
semantically search and categorize issues, topics or actions and thus
discover a more complete understanding without having to sort through
unwanted, inaccurate text.

"Using a semantic indexing rather than a keyword index of these government
Web sites is more helpful for all users to understand how their tax
dollars are being spent, how effective policies are for current economic
recovery efforts, and to substantiate government officials' aim to be
more open and inclusive," said Brooke Aker, CEO of Expert System USA.

Semantic indexing is far superior to keyword indexes. For example, on
Recovery.gov, a search for the word "money" will return documents only
with the term "money." A keyword index limits our understanding since it
only returns one concept "as a medium of exchange." The semantic index,
however, will know that alternative forms of money in the context of
"medium of exchange" would include such things as cash, currency, tender
and even appropriations or amounts -- government short hand for money.

This unique technology is a map of all English words, definitions and
their relationships to one another. The semantic index can understand all
the ways authors may express the same concept and give that to users.
Thus, a semantic index has better recall across the same set of
information than does a keyword index.

Citizens, policy makers and researchers can also use the Expert System
semantic index to gain better precision over the documents they receive
from a search. A search for "fruit" using a keyword index will likely
include documents about something to eat as well as the outcome of some
policy choice. But, the semantic index can distinguish between these and
allow the user to ask for, say, only the "outcome" context of fruit. This
saves the user from sorting through documents in the wrong context.

"The Obama Administration is using technology and communication in far
more advanced ways than any previous Administration," Aker said. "Semantic
technology is one of those tools that provide efficiency, clarity and
understanding that are the heart of government openness and
inclusiveness."
