Usually to get knowledge about some objects from Internet we use two stage process:

1. Google to get links;
2. Follow by the links to specific web sites and get information there.

Couple of examples:

Objects: ford,lamborghini Properties: expensive,cheep,luxury Search Engine: Google Number of Pages Found, ths expensive cheep luxury ford 11.3 840.0 445.0 lamborghini 268.0 37.8 337.0

Indexes (ratios of actual nubers of found pages to expected numbers) expensive cheep luxury ford 6.1 143.1 85.1 lamborghini 289.5 13.0 130.0

Objects: USA,Canada,Russia,Israel,Iraq Properties: recession,growth,trade,peace,war Search Engine: Google Number of Pages Found, ths recession growth trade peace war USA 260.0 975.0 1780.0 924.0 3260.0 Canada 254.0 1120.0 2970.0 1200.0 2290.0 Russia 219.0 572.0 1320.0 821.0 1240.0 Israel 212.0 473.0 1720.0 1590.0 1630.0 Iraq 238.0 491.0 1490.0 1340.0 3910.0

Indexes (ratios of actual nubers of found pages to expected numbers) recession growth trade peace war USA 98.6 120.5 86.1 70.6 118.6 Canada 88.5 127.2 132.0 84.2 76.6 Russia 143.3 122.0 110.1 108.2 77.9 Israel 102.9 74.8 106.4 155.4 75.9 Iraq 87.0 58.5 69.4 98.6 137.1

~ Number of pages = Yes = No

How it works?

googmeter gets number of found pages N(Obj, Prop) and creates contingency tables where rows correspond to Objects and columns to Properties.

From the tables we calculate Totals by columns - Tot(Obj) , rows - Tot(Prop) and overall Tot and then empirical probabilities

p(Obj) = Tot(Obj) /Tot , p(Prop) = Tot(Prop) /Tot.

After it we obtain expected number of pages

E(Obj, Prop) = Tot * p(Obj) * P(Prop)

and indexes

Ind(Obj, Prop) = 100* N(Obj, Prop) / E(Obj, Prop) .

GoogMeter prints Number of found pages N(Obj, Prop) and Indexes Ind(Obj,Prop) and visualizes the table plotting horizontal bars or bubbles that colored green if Actual Numbers are greater than Expected and red in opposite case.

There are too variants for bar's width (or bubble's volumes):

1. Width is proportional to contribution to Chi2 statistics ~ ( N - E )² / E
2. Width is proportional ~ | ln ( Ind / 100 ) | = | ln ( N / E ) |

Volumes of blue bubbles are proportional to numbers of pages found, volumes of red and green bubbles are proportional to deviations of found numbers from expected.
If the found number is greater/less then expected, the bubble is green/red
so large green/red bubbles show often/rare combinations of words.

Anyway - green means "Yes" and red means "No"

Click and Enjoy, GoogMeter is free and open source!
