Reverse engineering

In order to make my proposal to build a mini-Wikipedia challenging I present to you here a few result pages and ask:

How was this done?

What is the algorithm that produced the following results?

1. en.wikipedia.org/wiki/Reverse_engineering
o Reverse engineering (RE) is the process of taking something (a device, an electrical component, a software program, etc.) apart and analyzing its workings in detail, usually with the intention to construct a new device or program that does the same thing without actually copying anything from the original.The verb form is to reverse-engineer, spelled with a hyphen.

2. http://en.wikipedia.org/wiki/Russian_Blue
o The Russian Blue is a breed of cat.It has a lean medium-sized body and a short, plush blue (a blueish-grey that is the dilute expression of the black gene) coat.This coat is unique to the breed as it is a double coat, with the undercoat being a soft and downy and the longer guard hairs an even blue with the silver tips.This "tipping" gives the coat a shimmering appearance. Its eyes are green and ideally should be dark and vivid.

3. http://en.wikipedia.org/wiki/Scottish_Fold
o The Scottish Fold is a breed of cat with a natural mutation to its ears.The ear cartilage contains a fold so the ears bend forward and down towards the front of their head.

4. http://en.wikipedia.org/wiki/Savannah
o Savannah (Cat) is a breed of cat (a cross between the serval and the domestic cat).

5. http://en.wikipedia.org/wiki/Serval
o The Serval (Leptailurus serval, sometimes Felis serval) is a medium-sized African wild cat: length 85 cm, plus 40 cm tail. It is a slender animal, with long legs and a fairly short tail. The tall, oval ears are set close together.

6. en.wikipedia.org/wiki/Siamese_%28cat%29
o The exact origins of the breed are unknown, but it is believed to be from South-East Asia, and may be descended from the sacred temple cats of Siam (hence their name). The breed was first seen outside their Asian home in 1884, when the British Counsul-General in Bangkok, Mr Owen Gould, brought a pair of the cats back to Britain for his sister, Mrs Veley (who went on to be co-founder of the Siamese Cat Club in 1901).The cats were shown at the Crystal Palace in 1885, and the following year another pair (with kittens) were imported by a Mrs.

7. http://en.wikipedia.org/wiki/Sagwa%2C_the_Chinese_Siamese_Cat
o Sagwa is a literary cat character introduced to the United States by way of a children's book Sagwa, the Chinese Siamese Cat by author Amy Tan.Sagwa's popularity with children prompted an educational cartoon series of the same name on PBS. In the series, which takes place circa 1900, Sagwa has fun but learns valuable life lessons.

8. http://en.wikipedia.org/wiki/Singapura_%28cat%29
o The Singapura is a recognized breed of cat. These exerts are from the UK Singapura Cat Club."The Singapura is an alert, healthy, medium sized cat of foreign type. The body has good bone structure and is moderately stocky and muscular, yet gives an impression of great elegance.

9. http://en.wikipedia.org/wiki/Snowshoe_%28disambiguation%29
o Snowshoe (cat), a breed of cat.

10. ://en.wikipedia.org/wiki/Sokoke
o The Sokoke is a breed of cat.The original name of the breed was Khadzonzos. The Khadzonzos cats were discovered in the Sokoke-Arabuke forest, on the Kenyan coast, by Jeni Slater in 1978.Gloria Moeldrop, a friend of Slater's, brought some of the cats home with her to Denmark to breed. In 1990, she imported more cats from Kenya to strengthen the breeding stock.

11. http://en.wikipedia.org/wiki/Tabby_cat
o Tabby cats are often mistaken as a certain breed of cat. The term tabby actually refers to the stripes, dots and swirling patterns of the cat's coat. The tabby pattern is believed to be the original basic cat pattern, and the closest to their distant ancestors. Tabby coloration is found in many breeds of cat, as well as among the general 'moggy' (mixed-breed or mongrel) population. When cats are allowed to breed randomly, the coloration of the population tends toward brown mackerel tabbies with green eyes, leading geneticists to believe that this is the common wild phenotype of the domestic cat.

12. wikipedia.org/wiki/Tigon
o A tigon is the artificially bred hybrid of a male tiger and a female lion.The tigon is not as common as the converse hybrid, the liger.Tigons presumably do not occur naturally in the wild, as the lion and tiger have very different behaviours and habitats.

13. en.wikipedia.org/wiki/Show_cat
o The entire Cornish Rex breed can be traced back to a single parent animal with an unusual genetic mutation producing a curly coat. Both the Burmese and Tonkinese breeds can be traced back to a single cat, Wong Mau, which was brought from Burma in the 1930s.Breeders continually strive to eliminate negative characteristics that various cat breeds exhibit as the breeds are developed. There is not really any such thing as a 'purebred' cat since all registered breeds began as random bred cats.

14. http://en.wikipedia.org/wiki/Tonkinese_%28cat%29
o Tonkinese are a medium-sized short-haired cat breed distinguished by points as with Siamese and Himalayans.They are commonly referred to as 'Tonks'. As with many cat breeds, the exact history of the Tonkinese varies to some degree depending on the historian.

15. ://en.wikipedia.org/wiki/Turkish_Angora
o The Turkish Angora is a breed of domestic cat.Turkish Angoras are one of the ancient, naturally-occuring cat breeds, having originated in central Turkey, in the Ankara region.

16. http://en.wikipedia.org/wiki/Turkish_Van
o The Turkish Van is a rare, naturally occurring breed of cat originally found in the Lake Van region of southeastern Turkey.The word van refers to their color pattern, where the color is restricted to the head and the tail, and the rest of the cat is white. It is the maximum expression of the piebald white spotting gene that makes the van pattern.
