Subject: BNCweb--A Web-based Interface to the British National Corpus

	

	
	We would like to announce the release of BNCweb, a web-based 
	interface to the 100-million word British National Corpus.
	
	
***What is BNCweb?***

BNCweb is a user-friendly, web-based client program for searching and 
retrieving lexical, grammatical and textual data from the British 
National Corpus (BNC). It relies on the BNC server program, SARA, to 
provide a convenient interface between the user and the rich variety 
of annotated text in the 100-million word BNC. Thanks to its 
integration of MySQL, a very fast SQL-database server, BNCweb is able 
to extend the functionality of SARA. It thus offers a whole range of 
additional features for corpus analysis, such as:

- distribution of the query result over various metatextual categories
- very flexible collocation analysis
- tag sequence search (for retrieving grammatical patterns)
- sort
- user-definable frequency lists (restricted e.g. to certain 
patterns, POS-tags)
- etc.

BNCweb can be accessed by several users at the same time - 
performance will vary according to your hardware set-up. At Zurich 
University, we have had 20 concurrent users without experiencing a 
major slow-down of the system. Of course, BNCweb can also be used on 
a stand-alone computer (i.e. with the web-browser and web-server on 
the same machine).

Please consult the BNCweb homepage (http://homepage.mac.com/bncweb) 
for more detailed information about the individual features. An 
extensive manual is also available.


***Availability***

BNCweb is now available for non-commercial use. You can order your 
own copy for a shipping and handling fee of 30 Euro. (No restrictions 
apply as to the number of installations or users per institution.) 
This fee includes notification of future upgrades and some basic 
support by e-mail. For more extensive support, special conditions 
apply. Further information can be found at 
http://homepage.mac.com/bncweb.


***System and Installation Requirements***

BNCweb requires no special installation procedure or client program 
*on the part of the end user* - any web-browser (under any kind of 
operating system) can be used to access the BNC via the internet or a 
local area network.

On the server side, a BNCweb installation requires:	

- a UNIX server (e.g. Linux, Mac OS X)	- a full installation 
of the BNC World Edition--see http://info.ox.ac.uk/bnc/
- some additional UNIX tools (e.g. MySL, Perl)
In its current version (2.0), BNCweb is exclusively compatible with 
he BNC World Edition. Users with an installation of the first 
elease of the BNC will have to purchase a copy of the BNC World 
dition before being able to use BNCweb.
