Documents can change over time.

"""The log:semantics of a document is the formula.
achieved by parsing representation of the document"""

includes the act of accessing the document to get the representation. 
Passing on a log:semantics seems to imply passing on that act.

Merge two documents with two log:semantics assertions ...

"Graph" 1:

<http://example/temperature> log:semantics { :here :currentTemp 15 . }

"Graph" 2:

<http://example/temperature> log:semantics { :here :currentTemp 4 . }

so I think that's a "no", it's not an owl:FunctionalProperty.
