Mahout currently has Collaborative Filtering User and Item based recommenders K-Means, Fuzzy K-Means clustering Mean Shift clustering Dirichlet process clustering Latent Dirichlet Allocation Singular value decomposition Parallel Frequent Pattern mining Complementary Naive Bayes classifier Random forest decision tree based classifier High performance java collections (previously colt collections) A vibrant community and many more cool stuff to come by this summer thanks to Google summer of code

So schreibt z.B. ein Nutzer (leider ohne Quellenangabe, anscheinend aus dem Buch Aufbrechen: warum wir eine Exzellenzgesellschaft werden müssen von Gunter Dueck) Interessant: “Die IBM-Bibliothek ist abgeschafft worden. Man hat berechnet, dass die meisten Bücher nie angefasst werden. Es ist billiger, sich Bücher bei Bedarf von Amazon schicken zu lassen, und zwar jedes einzelne Mal, wenn man in ein Buch schauen will. [...] Allein die Bibliothekarin kostet mehr als alle Amazon-Rechnungen zusammengenommen.” Ich schreibe eigentlich gar nichts direkt in Facebook, meine Einträge werden aus verschieden Quellen bei Friendfeed gesammelt und das Ergebnis in Facebook aggregiert. Allerdings muss man dann auf Friendfeed die Quellen entsprechend zusammenstellen

ZXing (pronounced "zebra crossing") is an open-source, multi-format 1D/2D barcode image processing library implemented in Java. Our focus is on using the built-in camera on mobile phones to photograph and decode barcodes on the device, without communicating with a server. We currently have support for: * UPC-A and UPC-E * EAN-8 and EAN-13 * Code 39 * Code 128 * QR Code * ITF * RSS-14 (Stacked and Limited) * Data Matrix ('alpha' quality) * PDF 417 ('alpha' quality)

LIBLINEAR is a linear classifier for data with millions of instances and features. It supports L2-regularized logistic regression (LR), L2-loss linear SVM, and L1-loss linear SVM. Main features of LIBLINEAR include * Same data format as LIBSVM, our general-purpose SVM solver, and also similar usage * Multi-class classification: 1) one-vs-the rest, 2) Crammer & Singer * Cross validation for model selection * Probability estimates (logistic regression only) * Weights for unbalanced data * MATLAB/Octave, Java interfaces

The World Digital Library will make available on the Internet, free of charge and in multilingual format, significant primary materials from cultures around the world, including manuscripts, maps, rare books, musical scores, recordings, films, prints, photographs, architectural drawings, and more. The objectives of the World Digital Library are to promote international and inter-cultural understanding and awareness, provide resources to educators, expand non-English and non-Western content on the Internet, and to contribute to scholarly research.

Do you have dozens of PDF files from your favorite scientific articles scattered on your harddrive? Do you also try to desperately organize them by renaming and archiving them in folders? But like the piles of printed articles on your desk, you can't keep up with all the new papers you download, and despite all your efforts it has become impossible to find that one article.
