Alternative text (or alt text) is text associated with an image that serves the same purpose and conveys the same essential information as the image. [1] In situations where the image is not available to the reader, perhaps because they have turned off images in their web browser or are using a screen reader due to a visual impairment, the alternative text ensures that no information or ...

In other words, the "it is a link to further information" (i.e. a link to the file information page) is something all images have in common, but the alt-text for an image is part of the page (not the image) and helps to integrate the image into the page it is being used on (i.e. this image is being used here for this reason, and [where it helps ...
Check intensity: How often and for which types of document fragments (paragraphs, sentences, fixed-length word sequences) does the system query external resources, such as search engines. Comparison algorithm type: The algorithms that define the way the system uses to compare documents against each other. [citation needed] Precision and recall
