Abstract

The semantics of UML [3] is for a large part given in English. The drawback of Eng-lish is its ambiguity, which makes it unclear and ambiguous. But the benefits of Eng-lish are its power and flexibility, which allow it to deal with a slightly inconsistent terminology. Formalizing UML will imply recognizing the occurrences of these in-consistencies and coping with them in a systematic way. In this paper, we show some problems with the UML terminology and we propose an approach to deal with these problems.

Ambiguity

Ambiguity is the type of meaning in which a phrase, statement, or resolution is not explicitly defined, making several interpretations plausible. A common aspect of ambiguity is uncertainty. It is thus an attribute of any idea or statement whose intended meaning cannot be definitively resolved, according to a rule or process with a finite number of steps. (The prefix ambi- reflects the idea of "two," as in "two meanings.") The concept of ambiguity is generally contrasted with vagueness.

Syntactic ambiguity

Syntactic ambiguity, also called structural ambiguity, amphiboly or amphibology, is a situation where a sentence may be interpreted in more than one way due to ambiguous sentence structure. Syntactic ambiguity does not come from the range of meanings of single words, but from the relationship between the words and clauses of a sentence, and the sentence structure hidden behind the word order. In other words, a sentence is syntactically ambiguous when a reader or listener can reasonably interpret one sentence as having multiple possible structures.

Semantics

Semantics () is the study of reference, meaning, or truth. The term can be used to refer to subfields of several distinct disciplines, including philosophy, linguistics and computer science. In English, the study of meaning in language has been known by many names that involve the Ancient Greek word σῆμα (sema, "sign, mark, token"). In 1690, a Greek rendering of the term semiotics, the interpretation of signs and symbols, finds an early allusion in John Locke's An Essay Concerning Human Understanding: The third Branch may be called σημειωτική [simeiotikí, "semiotics"], or the Doctrine of Signs, the most usual whereof being words, it is aptly enough termed also λογικὴ, Logick.
