This theory demonstrates a defaults-based treatment of the notion of paradigm relations, introduced in section 1.0.1 and discussed in terms of default and multiple inheritance in section 1.3. It also shows how defaults capture semi-regularity. The illustrative data are Russian noun morphology; refer to (6) on page 4.
This fragment (ch23_rusnoms.dtr) is discussed in chapter 2 and chapter 3, and is modified later as part of the account of derivation in chapter 7. It accounts for the first 1500 noun lexemes in Zasorina's (1977) frequency dictionary. As it is an account of inflection, we have not linked lexemes which have a clear derivational relationship (e.g. brat and bratstvo), but the modifications for derivation in chapter 7 would allow this kind of relationship to be expressed.
This second theory introduces inheritance-based derivational relatedness, thereby offering a defaults-based account of (1) category changing derivation, (2) conversion, (3) transposition and (4) category preserving derivation. For (4) the theory is able to account for the difference between head-marking and non head-marking types of category preserving derivation.
This is the first in a series of theories demonstrating a defaults-based account of Russian derivation. In this first one we show derivation as multiple inheritance from a Lexeme node and a WFR node. *Choose Monaco 10 point.*
