Resumption and Extraction in an Implemented HPSG of Hausa
Berthold Crysmann · 2015
In this paper, we describe the treatment of extraction in HaG, an emerging computational grammar of Hausa, concentrating on the intricate patterns of interaction between resumptive and gap strategies.We shall argue with Tuller (1986) that Hausa resumption (both overt and covert) opens up the possibility for relativisation only to escape well-attested extraction islands in the language.As suggested by the mutual compatibility of gaps and resumptives in ATB extraction, however, we shall conclude that both strategies must be regarded as unbounded dependencies (UDCs) to be modelled via the feature in HPSG.We shall discuss how the treatment of UDCs has been generalised, in HaG, to permit more than one simultaneous dependency, and focus in particular on how the distinction between true gaps and resumptive elements can be exploited to address efficiency issues.
