By means of the Cross-Topic Analysis it is possible to understand how different analysis relate one each other. This is performed through the computation of joint frequency tables and conditional probability tables.
For instance, the cross-topic analysis allows to understand how each trending topic is related to the sentiment. The Sentiment X Topic table represents the percentange of occurence (or joint frequency) of each analysed topic with respect to the three level of sentiment (positive, neutral and negative).
It is also possible to estimate the probability of a document or post of being negative, neutral or positive given the fact that it speaks about a certain topic. This is done by means of the conditional probability tables, or using the Polar Plot.
In this analysis the polar plot shows immediately that posts related to Media & Show or Gender Disparity have higher probability of being negative, while the oother are most likely neutral or positive but with a lower probabilty.
However, the cross-topic analysis is not limited to “cross” trending topics with sentiment. It allows to combine together any analysis you are interested in.
