What is "Po"?

po as a “meaning” weight: po is a weighting schema used in WIH prototype (Word Intelligent Handler). It is based on a list of prefixes and words that are frequently used in Spanish to denote negative forms, or alteration in the strength of the meaning [1][2]. In tables I and II there are certain EBHs used for opposition and ambiguity processing.

Table I. EBH for opposition

Table II. EBH for ambiguities

Opposite and ambiguous EBH are weighted according to its general interpretation and used to derive po value [2]. Figure 1 shows the equation to get po value for any sentence.

Here n is the number of words in the sentence, p(wi) is the weighting heuristic when it is applied to some HBE named w. It has been shown in [3] that po has the fllowing properties:

1. it represents EBH's neighborhood.
2. it could also be used to automatically distinguish between the text profiles indicated in Table II. [4].

Table II. Text profile
1. it statistically shows some statements in [5] linking language expressions with culture, geography, subject and author intention.
Table III. Author profile
