We are very pleased to announce the release of SenseClusters version 0.93. This version marks our first steps towards supporting Latent Semantic Analysis in addition to our native SenseClusters methods.
In this version we now support word clustering (feature clustering really, as it is not limited to just unigrams or single words) that is based on a feature by context representation. In other words, features are clustered based on the contexts in which they occur. These matrices can optionally be reduced with SVD prior to clustering. We refer to this as LSA feature clustering. These feature by context representations are what we believe characterizes LSA, and makes it different from our native SenseClusters methods. We have supported a form of word clustering prior to this release, and it is based on a word by word representation, that is words are clustered based on the words with which they occur. You can download version 0.93 from sourceforge: http://sourceforge.net/projects/senseclusters/ As a preview, in version 0.95 we will have support for doing context discrimination "the LSA way". The features found in contexts to be discriminated will be represented by vectors that show which contexts those features occur in, thus providing a second way of doing order 2 representations. At present our native SenseClusters order 2 methodology is based on replacing the words in the contexts to be clustered with vectors showing the words with which they occur. There are some other significant changes in version 0.93, among them that SenseClusters now requires the use of Perl 5.8.5 or better. The most current version of Perl is 5.8.8 now, and 5.8.5 is several years old, so it is probably time to upgrade anyway if you are running something less than 5.8.5. Also, we have attempted to clarify the installation instructions further. We will continue to work on that in 0.95, hopefully making SenseClusters much easier to install. We think the instructions are quite a bit better now, so please check them out: http://www.d.umn.edu/~tpederse/Code/SenseClusters-v0.93-INSTALL.txt The more detailed ChangeLog for 0.93 can be found here: http://www.d.umn.edu/~tpederse/Code/Changelog.SenseClusters-v0.93.txt Please let us know if there are any questions, and please do plan on upgrading to 0.93, or trying it out on the web interface: http://marimba.d.umn.edu/cgi-bin/SC-cgi/index.cgi We would be happy to answer any questions or receive any comments you might have.
