Linear Algebra: MPIA package
’Learning’ means building competence through (targeted) conversation between an aspirant and a typically more experienced other. Such conversation, – particularly when born digital in form of messages, essays, articles, or books available online –, can be subjected to analysis, looking into both the developed conceptual structures as well as the…

Linear Algebra: latent semantic analysis (lsa)
The basic idea of latent semantic analysis (lsa) is, that text do have a higher order (=latent semantic) structure which, however, is obscured by word usage (e.g. through the use of synonyms or polysemy). By using conceptual indices that are derived statistically via a truncated singular value decomposition (a two-mode…

CRAN task view NLP
PAL maintains the R task view on natural language processing, watching over the packages in the scope and helping with further development. Natural language processing has come a long way since its foundations were laid in the 1940s and 50s (for an introduction see, e.g., Jurafsky and Martin (2008): Speech…

cRunch infrastructure for computationally-intense performance analytics
cRunch is a service and an infrastructure for computationally-intense learning analytics. It supports researchers in munching away the data points, generated by learners online in the co-construction of knowledge – helping learners, faculty, and administration with living reports, created live from data. cRunch currently has three components: the studio, the…
