Google dataset linking strings and concepts. Tim Finin, 11:02am 19 May 2012 Yesterday Google announced a very interesting resource with 175M short, unique text strings that were used to refer to one of 7.6M Wikipedia articles.

Google dataset linking strings and concepts

This should be very useful for research on information extraction from text. “We consider each individual Wikipedia article as representing a concept (an entity or an idea), identified by its URL. Text strings that refer to concepts were collected using the publicly available hypertext of anchors (the text you click on in a web link) that point to each Wikipedia page, thus drawing on the vast link structure of the web.

The source code for a reference implementation of this framework has been made available on SourceForge, and later on the website of the Apache Software Foundation. Another use of UIMA is in systems that are used in medical contexts to analyze clinical notes, such as the Clinical Text Analysis and Knowledge Extraction System (CTAKES). Supercalculateur sémantique. "Watson" est un superordinateur de la firme IBM.

Supercalculateur sémantique

Il associe la puissance matérielle (quantitative) à la puissance logicielle (qualitative). Au plan matériel, Watson dispose d'un système d'exploitation GNU-Linux, composé de 10 racks contenant chacun 9 serveurs Power 750 montés en réseau. Chaque serveur possède 32 coeurs qui peuvent gérer un total de 128 tâches en parallèle. "Watson", qui compte donc au total 2 880 coeurs pouvant effectuer 11 520 tâches en parallèle, possède une mémoire vive de 15 000 Go (gigaoctets) et une puissance totale de 80 Tflop (téraflops).
