The SOMLib Digital Library - Related Projects

A number of sub-projects are related to or form a major part of the SOMLib project, which include the following:

parSOM: An implementation of the self-organizing map for parallell processing, developed and tested for Dual-processor Intel Celeron, Linux; 16-processor SGI PowerChallenge 10000XL, IRIX 6.2; 64-processor SGI Origin 2000, IRIX 6.5.3.
GHSOM : A growing hierarchical version of the self-organizing map, which completely adapts itself to the input space, creating a hierarchy of maps of different sizes according to the provided data.
libViewer: a metaphor-graphics based visualization of digital libraries allowing users to easily recognize and intuitively interpret information available about documents.
SOMeJB: The SOM-enhanced Jukebox Music Digital Library Project aims at creating a browsable music archive by combining a variety of technologies from the fields of audio processing, neural networks, and information visualization, to create maps of music archives. It is based on the self-organizing map (SOM), a popular unsupervised neural network, used to organize pieces of music available as, e.g., mp3 files, according to their musical sound characteristics, i.e. creating a kind of genre-based organization. The resulting map of the music archive can be explored, and new, unknown pieces of music similar to ones personal likings can be discovered.
