Question

pseudo-code, please

If a word has a tag O, it means that the word has nothing to do with the named entity (it is not a part of a named entity such as a location, person name, organization, and etc.)

If a word has a tag starting with B, it means that the word is the beginning of a named entity. For instance, the tag B-per means that the associated word is the beginning of a person's name. On the other hand, if a word has a tag starting with I, it means the word is inside a named entity. Hence, the tag I-per means that the associated word is inside a person's name.

Thousands O

of O

demonstrators O

have O

marched O

through O

London B-geo

Take the following lines in the file for example.

President B-per

Mahmoud I-per

Ahmadinejad I-per

said O

We know the words “President, Mahmoud, and Ahmadinejad” cover a named entity of the type person name.

Could you write pseudo code to pull the names out of a file that are stated in the example

Answer 1

Pseudocode:

Pseudocode in simple terms is step by step explanation of a program or arranging the sequence of tasks :

Here we have made use of If-Else as well as switch-case statement structure :

pseudocode for given scenario:

Using If-Else:

Begin

Input a word

If Word has Tag=”O”

                “Not a part of named Entity”

ElseIf Word has Tag=”B”

                “word is the beginning of a named entity”

ElseIf Word has Tag=”B-per”

                “associated word is the beginning of a person's name’

ElseIf Word has Tag =”I”

                “Word is inside named entity”

Else                //( Word has Tag =”I-Per”)

                “associated word is inside a person's name.”

End If

End

Using Switch case:

Begin

Input word(names out of file)

Case based on tag

                Case=”O”

                                Report “Not a part of named Entity”

                Case=”B”

                                Report “word is the beginning of a named entity”

                Case=”B-per”

                                Report “associated word is the beginning of a person's name’

                Case=”I”

                                Report “Word is inside named entity”

                Case=”I-per”

                                Report “associated word is inside a person's name.”

                End Case

End
