Text: The functions provided by Cogito Categorizer and
Cogito Discover enrich documents, CMS and web pages
with semantic information and metadata, to make the
contents fully accessible, manageable and interoperable.
Cogito Categorizer automatically classifies large volumes
of documents based on the main topic and other
customizable criteria. It assigns with precision and to
any kind of text, one or more categories depending
on the content, thus enabling knowledge workers a
more effective way to retrieve relevant information.
Cogito Discover automatically identifies in the
documents, the most relevant concepts, events and
other specific information (people, companies, places,
amounts, addresses etc.), and extracts the most
important data included in the document. It
automatically tags the documents, normalizing the
data and generating the metadata map, to streamline
access to the available information.

Cogito Categorizer and Cogito Discover
reduce the search time and simplify
the access to any content;
enable a more effective management
of information, making it automatic
and based on objective criteria;
identify useful information
immediately and retrieve data that
traditional technologies cannot extract.

available inside the company and on the
web has made knowledge management
activities increasingly difficult and
The issue is evident to any company
dealing with a large collection of
intellectual capital and unlimited web
resources, but also more simply to each
individual when, for example, we need
to find an old email message.
In order to extract value from the
documents available, we need tools able
to understand quickly what the texts are
about and what data they contain.

Semantics is the only technology which,
by understanding the correct meaning
of each word, is able to find in a sea of
documents only that which is relevant,
and only when it is necessary.

taxonomies including thousands of specific categories.
Customizable extraction of entities and events

“Ban Ki-moon” refer to the same person.
