STL-MPI is an extension to MPI to support easy transfer of STL objects. It allows tight integration of MPI with objects from the C++ Standard Template Library, assisting the development of efficient parallel programs using message-passing in C++. STL-MPI provides a transparent and unified mechanism in C++ to transmit STL containers in an object-oriented and type-safe manner. It supports nested containers for data transport.
OpenHTMM is an implementation specifically designed to facilitate research into Hidden Topic Markov Models methods. Hidden Topic Markov Models (HTMM) is a method of analyzing a docyment by imposing a temporal Markov structure on the document. In this way, it is able to account for shifting topics within a document. In so doing, it provides a topic segmentation within the document and also seems to effectively distinguish among multiple senses that the same word may have in different contexts within the same document.
