I can give you three data points from my own personal experience.

1. I have abandoned the quest for natural language, and invented
my own knowledge representation language, MKR, which is 
sufficiently English-like that non-experts can use it as an interface.
Queries are expressed in MKR, and executed by my MKE program.
My MKE program can translate MKR to/from OWL.

2. OpenCyc intends to have an English interface to their KB, but
they haven't reached their goal as yet.  They are currently working
on an OWL interface to the KB.  
OpenCyc has a primitive CycL-to-English generator operational.
They have no English-to-CycL translator.  
They do have a "dictionary assistant" which uses WordNet 
to guide the user in translating from English to the corresponding 
CycL concept.  (I haven't used the dictionary assistant yet, 
that's on my to-do list.)  OpenCyc also has a KB browser which 
searches for matching CycL concepts, which is very useful.  
In this case, it is the human who is translating from English to CycL.

3. There are numerous researchers working on KB systems
which use English as the knowledge representation language.
In this scenario, there is no translation required.
