This package consists of Perl modules along with supporting Perl programs that
implement the semantic relatedness measures described by Leacock Chodorow
(1998), Jiang Conrath (1997), Resnik (1995), Lin (1998), Hirst St Onge (1998)
and the adapted gloss overlap measure by Banerjee and Pedersen (2002). The Perl
modules are designed as object classes with methods that take as input two word
senses. The semantic relatedness of these word senses is returned by these
methods. A quantitative measure of the degree to which two word senses are
related has wide ranging applications in numerous areas, such as word sense
disambiguation, information retrieval, etc. For example, in order to determine
which sense of a given word is being used in a particular context, the sense
having the highest relatedness with its context word senses is most likely to
be the sense being used. Similarly, in information retrieval, retrieving
documents containing highly related concepts are more likely to have higher
precision and recall values.
A command line interface to these modules is also present in the package. The
simple, user-friendly interface returns the relatedness measure of two given
words. A number of switches and options have been provided to modify the output
and enhance it with trace information and other useful output. Details of the
usage are provided in other sections of this README. Supporting utilities for
generating information content files from various corpora are also available in
the package. The information content files are required by three of the
measures for computing the relatedness of concepts.
WordNet::QueryData provides a direct interface to the WordNet database files.
It requires the WordNet package. It allows the user direct access to the full
WordNet semantic lexicon. All parts of speech are supported and access is
generally very efficient because the index and morphical exclusion tables are
loaded at initialization. This initialization step is slow (appx. 10-15
seconds), but queries are very fast thereafter---thousands of queries can be
completed every second.

* Fixed a critical security bug with RSA signature
verification. Mitigating factors: DSA is used by default (not
vulnerable). Also, the attack requires that attacker has the
public key and the attacker needs to precompute the signature
data so, that it looks like a valid PKCS#1 signature. This is a
non-trivial task to perform without the private
key. Nonetheless, all users should update their servers and
clients as soon as convenient. Workarounds are to not use RSA
keys as host keys (though connecting to existing hosts with RSA
hostkeys poses a serious risk with a vulnerable client), and
disabling publickey authentication. Update your clients and
servers.
Update MASTER_SITES, remove sites that are down or no langer carry ssh2
and add some new.
- Turn Kerberos and group writeability support into knobs so one hasn't to
edit the Makefile.
- Remove dependency on security/tcp_wrapper for tcp-wrapper support on
systems < FreeBSD 4.0, that port is no longer persistent.
- Fix pkg-plist for WITH_STATIC_SFTP case.
- Replace referneces to /etc/ssh2/* in man pages with references to
PREFIX/etc/ssh2/* in order to better fit for FreeBSD.
- Replace "$(ETCDIR)" in ssh_dummy_shell.out with PREFIX/etc.
- Remove duplicated mechanism for generating the host key if an old one isn't
found in the post-install target in the Makefile of the port, this is
already done by the generate-host-key target in WRKSRC/apps/ssh/Makefile.
- Fix differences between the install action done when installing the
package versus installing the port. I.e. make the package create the host
key with what ever bits ssh-keygen2 defaults to (currently 2048) instead
of 1024 bits, copy over the configuration files for ssh2 and sshd2 from
the examples if not already existent and create the directories for the
global host keys and known hosts files.
- Add some foo to pkg-plist to remove as much as possible from PREFIX/etc/ssh2,
i.e. configuration files that don't differ from the corresponding examples
and empty directories. Inform the user to remove what's left over if any.
- Use _PATH_STDPATH instead of _PATH_DEFPATH so that the default PATH gets
set to "/usr/bin:/bin:/usr/sbin:/sbin:PREFIX/bin" instead of
"/usr/bin:/bin:PREFIX/bin". Using _PATH_STDPATH is consistent with OpenSSH
and seems more usefull. One might want to patch ssh2 to also use login_cap(3)
so that e.g. PATH gets picked up from whatever is defined in /etc/login.conf.
- Change MAINTAINER.
- Replace "share/doc/ssh2" with %%DATADIR%% in pkg-plist.

test the perl backend
- dynamically create pkg-plist in pre-install instead of post-install
to simplify things and guard against changes in bsd.port.mk
- bump portrevision
