-    If a file, F, is copied from one directory to another, we may want to say that
-    these are both the same file, just in a different location. We may say that
-    the file in the first directory, F1, is a specialization of F, and that the
-    file in the second directory, F2, is a specialization of F. Note that it is
-    the context (location) rather than content of the file that changes in this case.

     The above are just some examples of where we may want to connect entities by
     saying that they refer to the same thing, but at different levels of specialization.
     PROV also allows us to more generally draw a connection between two descriptions
-    of the same thing, even if not at different levels of specialization. For example,
+    of the same thing, even if not at different levels of specialization, describing the
+    entities as <i>alternates</i> of each other. For example,
     two versions of the webpage above, W1 and W2, are alternates of each other because
     they describe the same webpage.

+    (according to our model) these are both the same file, just in a different location.
