Using the TeCFlow taxonomy feature allows us to identify the most significant messages about the brands we are most interested in. The taxonomy:
loudspeaker brand
Bose
Klipsch
Denon
Marantz
Polk
will categorize documents about the loudspeaker brands Bose, Klipsch, Denon, Marantz, and Polk into 5 clusters. Figure 20 displays the result of clustering the documents into these 5 categories.

Figure 20 also show a pop-up window brought up by the user, which lists all the documents about "Polk", sorted by significance. The most highly-ranked document tells that Chris "would take BA over Polk any day", an open invitation for Polk to get back to Chris and ask him why he got this unfavorable opinion about their product.

Finally, figure 21 shows us when in time what brand was the hottest. For example, discussion about paradigm speakers peaked around day 40. This means, at this point in time group betweenness centrality was high (the light yellow line), as was betweenness centrality of term "paradigm". Discussion about Denon, on the other hand, was relatively flat for the first ninety days, but became the dominant issue in days 92 to 120.
