Texis Customer Spotlight: nMatrix
Litigation is a booming business in the United States. That's
not good news to some, but it creates interesting technology
challenges. Larger and more complex lawsuits entail larger and
more complex document management needs.
Some of the largest U.S. law firms, such as Skadden Arps, rely
on Texis to search and manage legal documents through an
application developed by Thunderstone integrator nMatrix Inc. The
specialty of nMatrix is managing the "discovery" phase
of U.S. legal proceedings.
In discovery, the parties provide the court with documents
that may contain evidence relevant to the case. In major cases,
millions of documents may be collected. They will be in many
different electronic formats, or on paper that must be scanned
and converted to searchable text through OCR process. The lawyers
involved must search through the documents looking for relevant
The nMatrix system, called DocuMatrix, is unique in providing
both full-text searching as well as classification and tagging.
At the beginning of the process, a document is imported as an
unstructured text object. Lawyers can immediately search through
the material using Texis's various advanced search techniques.
The approximate pattern matching tools are especially important
for searching through OCR'd material which typically contains
many typographical errors.
But that's not all. After a document is reviewed, authorized
users tag it with various structured information, such as the
names of people mentioned, dates, subjects, and many other
details. Each entry becomes immediately searchable itself. In
addition, the entered data is used for browsing and sorting the
Texis's database characteristics make all this easy to
accomplish. An administrator may specify the needed data fields,
which are different from case to case. For any field, the
administrator may designate a list of values to select from;
others fields, such as a description, may allow free text entry.
Users may search across any combination of the original text and
We studied other search engines and found Texis to be
the best suited to these needs because of it's superior database
integration. This system has grown to be quite complex, but Texis has accommodated
all the new requirements. It is really very versatile.

An example of the complexities involved is access control.
Users may be restricted to viewing only certain documents or even
certain fields. Also, nMatrix recently added a feature allowing
users to define their own thesauri for each case. Searches will
automatically search for all the specified synonyms of a term in
nMatrix also has found that the system is applicable to needs
beyond the discovery process. Its nSite! product is targeted at
knowledge management applications for lawyers as well as bankers
and other professions. This encompasses real-time notification of
newly arrived data, insuring that users stay up-to-date about
important business issues.
We're planning to expand our use of Texis in many
ways. Perhaps what's most important
about the role of Texis in our products, is the way it has
adapted to new requirements. We provide features and
functionality today that we hadn't even thought of several years
ago when we started with Texis. The fact that it has kept up with
our product evolution says a lot about its maturity and superior
