[Grammar] Difference in meaning of 'is known' and 'has been known'.

[Ishmam]

1. He has been known as the best guitarist of his country.

2. He is known as the best guitarist of his country.

I can not differentiate the meaning of these two sentences.
Are the sentences meaning same? If not, Then what is their meaning? I also want to know when to use 'is known', and when to use 'has been known'?

 

[Tarheel]

1. He has been known as the best guitarist of his country.

2. He is known as the best guitarist of his country.

I can not tell the difference between these two sentences.
Do the sentences mean the same thing? If not, Then what do they mean? I also want to know when to use 'is known', and when to use 'has been known'.

No, they don't mean the same thing.

Did you find those sentences somewhere, or did you make them up yourself?

Do you know the difference between past and present tense?

 

[Ishmam]

I made up by myself. Yes, I know the difference between present and past tense.

 

[Tarheel]

I made up [STRIKE]by[/STRIKE] myself. Yes, I know the difference between present and past tense.

You go first. What do the sentences mean, and how are they different?

 

[Ishmam]

In my point of view, first sentence indicates he has got his popularity recently, and second one indicates he is all time popular.

 

[Tarheel]

He is known as the best guitarist in his country.

He is widely regarded as the best guitarist of his country. (Presently.)

 

[Tarheel]

He has been known as the best guitarist in his country.

The "has been" indicates that the "knowing" took place in the past. However, additional context could change that. Perhaps:

He has been known as the best guitarist of his country for the past fifteen years.
