Automated treatment of electronic resources in the Scientific Information Service at CERN
No full textWe describe the automatic method of importation of meta data, developed in the Scientific Information Service, SIS, at CERN. The program, called Uploader, allows importation into the CERN library databases of bibliographic records and full text documents harvested from several Internet sources. The database sources offer essentially grey literature in physics and related subjects (e.g. DOE, KEK, Math-Doc, TipTop, etc.). This acquisitions policy is dependent on the automatic treatment of electronic resources and raises questions concerning the growing number of documents collected and on the enlargement of the subjects treated. Our constant efforts to enrich this meta data and to facilitate access to it, via the hyperlink model, brings new professional aspects to libraries
CERN openlab Whitepaper on Future IT Challenges in Scientific Research
No full textThis whitepaper describes the major IT challenges in scientific research at CERN and several other European and international research laboratories and projects. Each challenge is exemplified through a set of concrete use cases drawn from the requirements of large-scale scientific programs. The paper is based on contributions from many researchers and IT experts of the participating laboratories and also input from the existing CERN openlab industrial sponsors. The views expressed in this document are those of the individual contributors and do not necessarily reflect the view of their organisations and/or affiliates
From Fulltext Documents to Structured Citations: CERN's Automated Solution
No full textFor many years, CERN has been collecting all High Energy Physics documents to make them easy to access to physics researchers. A repository of up to 170,000 electronic documents is available via the CERN Document Server, the main gateway to CERN's digital library. On top of the creation of this digital archive, the computing support has been looking towards possible improvements in order to ease the task of searching through and reading the articles kept. In addition to the acquisition, cataloguing and indexing of standard metadata, specific treatments have been applied to the data itself.
In this paper, after a brief description of process applied to fulltext data, we shall focus on the specific work done within a collaboration between CERN, Geneva University and the University of Sunderland in order to successfully achieve the automated acquisition of structured citations from fulltext documents

An overview of the ATLAS High Level Trigger Dataflow and Supervision.
No full textThe ATLAS high-level trigger (HLT) system provides software-based event selection after the initial LVL1 hardware trigger. It is composed of two stages, the LVL2 trigger and the event filter (EF). The LVL2 trigger performs event selection with optimized algorithms using selected data guided by Region of Interest pointers provided by the LVL1 trigger. Those events selected by LVL2 are built into complete events, which are passed to the EF for a further stage of event selection and classification using off-line algorithms. Events surviving the EF selection are passed for off-line storage. The two stages of HLT are implemented on processor farms. The concept of distributing the selection process between LVL2 and EF is a key element in the architecture, which allows it to be flexible to changes (luminosity, detector knowledge, background conditions, etc.) Although there are some differences in the requirements between these subsystems there are many commonalities. An overview of the dataflow (event selection) and supervision (control, configuration, monitoring) activities in the HLT is given, highlighting where commonalities between the two subsystems can be exploited and indicating where requirements dictate that implementations differ. An HLT prototype system has been built at CERN. Functional testing is being carried out in order to validate the HLT architecture
CERN´s Library: members of the Scientific Information Service

The CERN Library
No full textAny advanced research centre needs a good Library. It can be regarded as a piece of equipment as vital as any machine. At the present time, the CERN Library is undergoing a number of modifications to adjust it to the changing scale of CERN's activities and to the ever increasing flood of information. This article, by A.G. Hester, former Editor of CERN COURIER who now works in the Scientific Information Service, describes the purposes, methods and future of the CERN Library
