Expert Solution & Answer
Chapter 8, Problem 13E
Explanation of Solution
Concept of frequency
- Frequency is the logarithm of number of occurrences of the term that is divided by the number of terms in the document.
- The concept of term frequency does not make sense when it comes to small
databases with few attributes with each containing only a few words. - The relevance of any term does not depend on the number of occurrences of the term.
- The logarithmic increase in the term frequency is not a good indicator when the domain is very small...
Explanation of Solution
Similarity of two tuples
- The similarity of two tuples can be measured by cosine similarity metric.
- The only difference is that the values that...

The table includes columns about customer location such as city, state, and country. You want to retrieve the first 3 letters of each country name. You decide to use the SUBSTR function to retrieve the first 3 letters of each country name, and use the AS command to store the result in a new column called new_country. You write the SQL query below. Add a statement to your SQL query that will retrieve the first 3 letters of each country name and store the result in a new column as new_country.arrow_forward
- We are considering the RSA encryption scheme. The involved numbers are small, so the communication is insecure. Alice's public key (n,public_key) is (247,7). A code breaker manages to factories 247 = 13 x 19 Determine Alice's secret key.
