The US data.gov people are very much aware of the need to do much more. (04)
For many, many decades, the US gov't has been the world's largest
publisher in terms of the number of documents, the number of distinct
pages, and the number of pages distributed. (05)
The huge bulk of that has been computerized for a long time, but the
amount of effort in trying to organize and relate enormous volumes
of material without semantic tagging is staggering. (06)
Trying to tag even a fraction of that data by hand would be
prohibitively expensive. Even for the small percentage that could
be tagged, the probability that the tags would be consistent or
significantly better than Googling is low. (07)
People are well aware of those issues, and the only solution is
to develop automated tagging tools. Hand-tagging of huge volumes
of data is not practical (or useful, even if it could be done). (08)
