The Predictive Quantities Indicator (PQI)

The Global Language Monitor’s proprietary algorithm, the Predictive Quantities Indicator (PQI) is the basis of our analytical engine.

The PQI tracks the frequency of words and phrases in the global print and electronic media, on the Internet, throughout the Blogosphere, as well as accessing proprietary databases (Factiva, Lexis-Nexis, etc.).

Once a keyword base index is created (including selected keywords, phrases, ‘excluders’ and ‘penumbra’ words), ‘timestamps’ and a ‘media universe’ are determined.

The PQI is a weighted Index, factoring in: Long-term trends, Short-term changes, Momentum, and Velocity.   As such it can create ’signals’ that can be used in a variety of applications.

Outputs include: the raw PQI, a Directional Signal, or a Relative Ranking with 100 as the base.

When analyzing words and phrases in political contexts, GLM uses the Political-sensitivity Quotient Index; when analyzing words and phrases in any other context, GLM uses a slightly different Predictive Quantities Indicator.  A third variation is used when analyzing words and phrases in commercial contexts called GLM’s TrendTopper software.

If you are interested in taking a closer look at the methodology underlying the PQI, see the slide show below.

A more detail look is available upon the signing of a NDA (non-disclosure agreement).  We will then take you through the methodology in detail as we have done with numerous technology organizations, government agencies, and media organizations.  If you would like to pursue this option, please send email to info@LanguageMonitor.com.
