I have had an initial look at the three new open data products that
contain road names: OS Open Map, OS Open Names and OS Open Roads. I was
hoping they might provide new information for improving the accuracy and
completeness of road naming, but my preliminary conclusion is that they
offer very little for this purpose. They all contain the same
misspellings as OS Locator. It has been noted that some OS paid-for
products (MasterMap in particular) don't contain most of the
misspellings, so I thought there was a small chance that one of these
products might not as well. I was also hoping that OS Open Names might
have included named residential paths (those where the names function as
a 'street' in an address), but that isn't the case. I suspect OS Open
Names includes exactly the same street names as OS Locator.
Secondly, I looked at whether OS Open Map or OS Open Roads could be used
to check whether segments of streets in OSM have the correct name - for
example whether names start and end in the correct position - but I have
found the naming of the streets in these data sets has been simplified
in a way that makes them unreliable for this purpose. For example, I
immediately noticed the name of the street on which I live is missing.
The street is present but is combined with an adjoining street and only
given the name of the other street. This simplification seems to have
been done everywhere. Therefore, please don't assume part of a street is
wrongly named based solely on this data, because it is unsuitable for
that purpose.

Hi all,
So the new OS OpenData that was discussed a few weeks ago is now
available:
https://www.ordnancesurvey.co.uk/blog/2015/03/new-os-opendata-products-now-live/
I think there could be many good uses of this including to help
validate some of our data.
If anyone is using this then let us know so that we don't duplicate work.
