Avian song learning is an important model system for understanding vocal learning in humans and other animals. Laboratory studies indicate that social interactions are critical for song learning, but field observations show that territorial males are aggressive to intruders, raising the question of whether young birds are tolerated, much less tutored in the wild. We examined how adult song spar...

We describe a basic Geo-coding service encompassing a geo-parsing tool and integrated digital gazetteer service. The development of a geo-parser comes from the need to explicitly georeference large resource collections such as the Statistical Accounts of Scotland which currently only contain implicit georeferences in the form of placennames thus making such collections inherently geographically...

Early work on natural language database query processing focused on theories of compositional semantics. Recent work concentrates on the translation of NL queries to SQL where semantics is primarily used in an ad hoc manner to guide syntactic translation. Here, we argue that there remains a need for an efficiently-implementable denotational semantics for NL DB queries, and show how this can be ...

(✓ 1 ✓ 2 ) := F ( ̄ ✓)(✓ 1 ✓ 2 ) (17) Since μ̇ > 0 and min (V ) > 0, we have (✓ 1 ✓ 2 ) 0 (G(✓ 1 ) G(✓ 2 )) (✓ 1 ✓ 2 ) 0 (V )(✓ 1 ✓ 2 ) > 0 for any ✓ 1 6= ✓ 2 . Hence, G(✓) is an injection from Rd to Rd, and so G 1 is a well-defined function. Consequently, (15) has a unique solution ˆ ✓ = G (Z). Let us consider an ⌘-neighborhood of ✓⇤, B⌘ := {✓ : k✓ ✓⇤k  ⌘}, where ⌘ > 0 is a constant that will ...
