You might add a nearer (better) neighborhood for that wrong "is part
of", but you will start a never ending game ;-)<br>
Seriously, the problem, as you conclude, is of course defining a
neighborhood with a node.<br>
The wiki says it can be tagged on polygons but, sadly, isn't clear
about relations, this is why it's a pity...<br>
<br>
I have the same problem with the ubiquitous concept or region (<a
href="http://wiki.openstreetmap.org/wiki/Tag:place%3Dregion">place=region</a>).
That is the funniest tag ever: it cannot be put on a node, nor on a
way, nor on an area nor on a relation!!! ;-)<br>
I have made a region <a
href="http://www.openstreetmap.org/relation/3769325">Ourthe-Amblève</a>
with a boundary=region relation (that I'd better call
touristic_region).<br>
It is not an administrative boundary, so, it has <b>no admin_level</b>.
(yet, I used admin_center for the tourist desk).<br>
I should try to make it a plain multipolygon with place=region.<br>
<br>
In that case, the boundary is well defined because the region is a
set of municipalities and I reused their borders as outer ways and
subareas. But what if those fuzzy borders are not well defined as
in your case?<br>
<br>
Well, that could be very simple in my mind. One uses a relation
that has no borders (hence not a boundary and not a multipolygon)
and one puts as members of this relation as many map elements as
necessary and aesthetically to best define it: streets, any node,
landuse areas, etc... Just a few nodes define your neighborhood
reasonably.<br>
The Nominatim's job is then to choose the place= relation whose
members surround the target.<br>
The Renderer's job is, as the best option failing to have a border
to outline the area, to highlight all of its members.<br>
<br>
Simple enough isn't it? And probably just a few details to settle
with Nominatim and Standard Map.<br>
And that would make less fuzzy place=region place=... articles too.<br>
<br>
Hoping this can help.<br>
