Lexical semantics

Tên sách (Title of document):  Lexical semantics Giới thiệu (Introduction):  The previous two chapters focused on the representation of meaning representations for entire sentences. In those discussions, we made a simplifying assumption by representing word meanings as unanalyzed symbols like EAT or JOHN or RED. But representing the meaning of a word by capitalizing it is a pretty unsatisfactorymodel. In this chapter we introduce a richer model of the semantics of words, drawing on the linguistic study of word meaning, a field called LEXICAL SEMANTICS lexical semantics. Before we try to define word meaning in the next section, we first need to be clear on what we mean by word, since we have used the word word in many different ways in this book. LEXEME We can use the word lexeme to mean a pairing of a particular form (orthographic LEXICON or phonological) with its meaning, and a lexicon is a finite list of lexemes. For the purposes of lexical semantics, particularly for dictionaries and thesauruses, we represent a LEMMA lexeme by a lemma. A lemma or citation form is the grammatical form that is used CITATION FORM to represent a lexeme. This is often the base form; thus carpet is the lemma for carpets. The lemma or citation form for sing, sang, sung is sing. In many languages the infinitive form is used as the lemma for the verb; thus in Spanish dormir ‘to sleep’ is the lemma for verb forms like duermes ‘you sleep’. The specific forms sung or carpets WORDFORMS or sing or duermes are called wordforms. ...
