Question

iii) Below are word counts of all nouns in the content of 3 web pages:

Page1.html Page2.html Page3.html Cat: 6 Cow: 6 Dog: 6 Home: 0 Mouse: 6 Pig: 0 Cat: 2 Cow: 2 Dog: 2 Home: O Mouse: 0 Pig: 0 Cat: 0 Cow: 1 Dog: 0 Home: 1 Mouse: 0 Pig: 1

Why a typical search engine would return Page2.html for a search query of “cats and dogs”?

Explain in your own words. Hint: use mathematics to explain.

Answer 1

When you type in more than one word in your search query, the Boolean AND operator is applied automatically by the system and combines the words. Do not type in the AND operator in your search query. Note that the word AND is not visible in your search query box. For example, if you want records that contain both the terms cats and dogs use:

cats dogs Each record will contain both terms cats AND dogs.

as here cats and dogs is used which is plural (cats and dogs) so the search engine will look for combination . and page 2 ia having more probability of these coming together so it returns Page2 and not Page1.
