LogonExtras

Overview

The LOGON tree makes a distinction between core components (a meager three gigabytes) and extra resources. Of these, the latter are not required for basic functionality but rather extend the LOGON tree with either proprietary third-party components (which can only be released to sites with appropriate licenses, typically members of the original LOGON consortium and external co-developers) or 'bulky' add-on resources, for example the LinGO Redwoods treebanks. This page provides information on which extra components exist in the LOGON SVN repository, and on how to activate these. Please note that, as of November 2008, the extra mechanism is new and remains to be tested. The information on this page is thus expected to change more frequently than some of the more basic documentation.

A Note on SVN Access Methods

All access to the LOGON SVN repository is via the HTTP protocol, typically to the address http://svn.emmtee.net/. The repository makes available the open-source LOGON core for anonymous read-only access. However, some of the add-on components can only be made available to authenticated SVN users, for example members of the LOGON consortium who have obtained licenses for the XLE LFG system or Allegro Common Lisp. Thus access to proprietary LOGON add-ons is regulated by SVN user accounts, where the original CVS accounts (and passwords) of the LOGON core developers team have been imported into the SVN repository. Please contact Stephan Oepen (oe at ifi.uio.no) for all questions relating to SVN user accounts and access rights.

Due to what appears to be a quirk] in how SVN handles [http://subversion.tigris.org/issues/show_bug.cgi?id=2712 mixed-access repositories] (i.e. repositories where some content is available to anonymous users, while other parts require user authentication), LOGON co-developers with SVN user accounts should connect through a different URL, viz. http://logon.emmtee.net/. In fact, both URLs (svn.emmtee.net and logon.emmtee.net) connect to the same physical SVN repository, they only differ in how they handle authentication. We hope to be able to consolidate access methods as newer SVN server revisions become available. In the following examples, we will use the world-readable SVN address for add-on resources that are publicly available, and the authenticated URL otherwise. Note however that, for those with valid SVN user accounts, it is always possible to uniformly use logon.emmtee.net as the base SVN URL.

Finally, the repository structure for add-on components reflects the distinction between tagged releases and the on-going trunk of development. Again, in adapting the example SVN commands suggested below, one may have to adapt directory names systematically (i.e. in ways that should be obvious), to reflect the choice of LOGON version currently installed. As of November 2008, we will assume that users install the HandOn release.

LOGON Redwoods Treebanks (Public)

The core directory lingo/redwoods/ contains the environment for semi-automated parse selection, realization ranking, and MR re-ranking experiments, using treebanked versions of the LOGON tourism corpora. In the core installation, this directory only contains the scripts and various configuration files for such experimentation, but not the treebanks or corresponding version of the ERG. To download the complete data, execute the following:

  cd $LOGONROOT/lingo/redwoods
  svn switch http://svn.emmtee.net/extras/handon/lingo/redwoods .

The SVN switch command makes a sub-directory of an SVN-controlled tree point to a different module from the same repository (i.e. it does not allow 'mixing and matching' across repositories). Please see the [http://svnbook.red-bean.com/ SVN documentation] for further information.

LOGON Norwegian–English Evolution Profiles (Public)

For several of the LOGON development data sets and the final test set (which only became available after completion of system development), historic incr tsdb() profiles (and fan-out log files) are available. These profiles document (in great detail) development progress made in the course of the original [http://www.emmtee.net/ LOGON] and [http://www.emmtee.net/index.php?page=7 HandOn] projects. To add this data to your LOGON tree, do

  cd $LOGONROOT/uio/evolution
  svn switch http://svn.emmtee.net/extras/handon/uio/evolution
