<Paola Di Maio>... To me semantics is the meaning of words, and semiotis is 
the meaning of non verbal communication, ie signs and symbols.
Please correct me where I am wrong,

Paola,

It was nice to hear from you, and i am glad that you enjoyed the company of 
Umberto Eco, who used to explain the complexitities of semiotics, meanings 
and ambiguity by fictional works, like The Name of the Rose.

As for the issue you arose, both versions have right to exist. In a narrow 
sense, Semantics is a linguistic branch caring about the language 
significance (linguistic signs), while in a broader meaning, it is what i 
suggested below.

[Semantics is aimed to provide a general theory of meaning relations between 
signs, constructs and things, assigning signification to syntactic 
structures and meanings to conceptual structures.]

At this level, we still abstracted from the pragmatic aspects of meaning, 
i.e., the user of the language (the agent of communication, interpretant); 
for the production of meaning as well as the processes whereby an agent 
(animal, human or robot)  assigns signification to signs more relate to 
empirical sciences such as psycholinguistics, history, anthropology.
Adding pragmatical and syntactic dimensions, you come to semiotics studying 
the nature of signs, which are generally of three sorts (natural, mental and 
cultural (conventional)), as it was discussed before: 
http://en.wikipedia.org/wiki/Sign.

Azamat
