I wrote:
In this view, a region is defined as an HTML fragment that shows information about one or more related items when it is rendered on a web browser.
Should it be:
From this view, a region is defined as an HTML fragment that shows information about one or more related items when it is rendered on a web browser.
This is the previous text:
… These issues have motivated a number of researchers to work on region extractors as a means to relieve information extractors from the burden of analyzing many regions of a web document that do not contain any relevant information.
Best Answer
in this view indicates that you are about to talk about the contents of the view, without any reference to who is observing it.
from this view indicates that some outside agent (a viewer, perhaps) is receiving information... from the view. For example,
Note that the subject of the main clause is one... the person who is getting the information from the view.
In your sentence, the subject of the main clause is region, which is not getting anything from the view: you are simply defining what it is. in this view is therefore the correct form.
