There are 4 specific types of analysis that will be done on the essays:

Gibberish Detection (Word Salad Detection)

A particular response or part of a response will be tagged as "gibberish" by the system, if the response is

A Word salad
Example

Question: Should uniforms be required for students in high-school?

Response: I beleive that uniforms should not be required etc etc. It is against the Freedom of Rights,discipline,First Amendment, Uniqueness, Individuality etc.

As you can see here, the response by the user is just basically a bunch of words that are related to the question.

OR

When the response contains a very badly structured sentence of paragraph, such that the person reading the essay cannot make out what the sentence is. Basically Gibberish! Eg: Uniform not I am school all should wear.

Irrelevance Detection

This part of E-valuador deals with responses that are not relevant to the specific prompt.

Example

Question: Should uniforms be required for students in high-school? implemented using Perl.

Response: I think high school students should not drink and drive etc etc.

This response is totally off the topic.

Fact Finder

This part of E-valuador tries to find fact stated in a response.

Example

"England is an island".

So, the program should be able to identify "Facts" and "opinions".

Example

Opinion: "I think the should be a law against drunk driving".

Fact: "The law prohibits driving under the influence".

Fact Checker

This part of E-valuador tries to identify actual facts and false facts.

Example

Correct Fact: "Minnesota is one of the states in USA"

Incorrect Fact: "Minnesota is a part of South America".

Hence, the program will be able to penalize the users response accordingly.
