Learn to Use DiscoverText to Gather and Classify Electronic Text
Free Webinar Tuesday at 12:00 PM EST

This Webinar introduces new and existing DiscoverText users to the
basic document ingest, search & code features, takes your questions,
and demonstrates our newest tool, a machine-learning classifier that is
currently in beta testing. This is also a chance to preview our "New
Navigation" and advanced filters.
DiscoverText's latest additions to our "Do it Yourself" platform can be
easily trained to perform customized mood, sentiment and topic
classification. Any custom classification scheme or topic model can be
created and implemented by the user. Automatic classifications can then
be set as document filters with adjustable thresholds. For those
following the trajectory of this software, this new set of
functionalities represents a leap forward.
You can also generate tag clouds and drill into the most frequently
occurring terms or use advanced search and use combinations of text and
metadata filters to create "buckets" of text. Next week we are
launching v2 of our tag cloud tool which will give users considerable
flexibility to build the visualization that best represent their
discoveries and inferences.
The system makes it possible to capture, share and crowd source text
data analysis in novel ways. For example, you can collect text content
off Facebook, Twitter & YouTube, as well as other social media or RSS
feeds. Dataset owners can assign their "peers" to coding tasks.
It is simple to measure the reliability of two or more coder's choices.
Crowd sourcing with 50 coders is no problem. A distinctive feature of
DiscoverText and its free, open source pre-cursor CAT, is the ability
to adjudicate coder choices for training purposes or to report validity
by code, coder or project. This technique allows researchers to report
validity scores (% valid) alongside reliability measures (Fleiss'
So, please join us Tuesday June 7 at 12:00 PM EST (Noon) for an
interactive Webinar. Find out why sorting thousands of items from
social media, email and electronic document repositories is easier than
ever. Participants in the Webinar will be invited to become beta
testers of the new classification application.
