Applications
The first application of the Data Projection Model was made in September 2006 for the IRS. Its purpose is to have an auditable view of TaxMap, i.e., answer questions about the origin of the topic names.

Data Projection Model: Applications |
TaxMap Page
|
In this TaxMap page, the topic is named "Income Earned Abroad" and it is related to two other topics whose names are "Income" and "U.S. Citizens and Resident Aliens Abroad". In the corresponding audited page, we see that the topic name originates from a document (p593-001), that it has been related through the containment rule (an automatic rule) to "Income", and has been related by experts (this is what "related PFT" means) to "Living Abroad". In addition, we can see the normalized form of the name and the address (URL) of the page within the system.
Note that the "related PFT" relation is to "Living Abroad" and not "U.S. Citizens and Resident Aliens Abroad". |

This page shows that experts have
decided that "American citizens abroad" and
"U.S. Citizens and Resident Aliens Abroad" should be
considered alternate names for "Living Abroad". The
name which is privileged, i.e. the one that appears in
the Related Topic link in the Tax Map page, is
"U.S. Citizens and Resident Aliens Abroad". The
current rule of the application is that the longest
name gets automatically privileged.
This image also shows that five
names have been discarded by experts and replaced by
the name "Living Abroad". When a name is replaced by
another, all the other attributes of the topic
(including its occurrences and relations to other
topics) are preserved. The reason for doing this is to
reduce the amount of "noise" in the system and to
concentrate meaning around subjects which have more
connections than they would have if left on their
own.
Many other properties of TaxMap are
shown in the audited view. If you want to see more of
it, please send an email to Michel
Biezunski.

What follows is an excerpt of the list of topic names that are automatically related through the containment rule: when one topic name is entirely contained inside another, they are related.
