File system permissions are your data’s first line of defense in a multiuser environment. A well-managed permission scheme ensures that your data is accessible and modifiable only by the proper people. The file system, after all, is the gateway to your data. An ineffective permission scheme is the equivalent of handing your data out to anyone who would express interest in it, or even worse, allowing them to destroy it. Furthermore, poorly implemented permissions can serve a different evil, preventing honest, hardworking Joe from accessing either his own documents or documents created by his collaborators.

PiMarking: co-located collaborative digital annotating on large tabletops

November 2012

There are situations under which co-located people are required to perform collaborative marking tasks: for example, human resource officers need to review resumes together and teachers need to grade answer sheets after an examination. In this poster, we introduce PiMarking, a collaborative system designed to accommodate user-authenticated marking tasks and face-to-face discussions on large-scale ... [Show full abstract] interactive tabletop surfaces. PiMarking makes it easy for user-differentiation, document sharing and synchronized marking among group members. PiMarking puts forward user permission management mechanisms, allowing three modes for document sharing: distributed copy, share display and synchronized marking. We conducted a preliminary study using a realistic resume marking task, which proved the effectiveness of the features provided by PiMarking.

WorkCache: Salvaging siloed knowledge

October 2016

The proliferation of workplace multimedia collaboration applications has meant on one hand more opportunities for group work but on the other more data locked away in proprietary interfaces. We are developing new tools to capture and access multimedia content from any source. In this demo, we focus primarily on new methods that allow users to rapidly reconstitute, enhance, and share ...

Corrective and preventive action in medical device manufacturing

November 2001

L. Schnoll

Corrective and preventive action (CAPA) is a system (or subsystem) to monitor the effectiveness of actions implemented to resolve past or potential nonconforming conditions. Within its documented quality system, a medical device manufacturer should have a high-level procedure that describes its CAPA program. This paper describes the basic sections of this procedure.

Geographic IR systems: requirements and evaluation

January 2005

Geographic information retrieval is a new and evolving domain. The development of GIR systems requires the analysis of requirements for such systems and, after systems are implemented their evaluation. This paper describes requirement analysis and evaluation for the SPIRIT system. Methods of user and system-centred evaluation are described and a methodology for building a document collection to ... [Show full abstract] facilitate derivation of measures of system performance, together with a new scheme for the evaluation of spatial and thematic relevance with respect to search results are introduced. The paper stresses the importance of developing approaches to evaluate GIR systems which holistically evaluate user interactions as well as measures of system performance.

The Use of the Dublin Core in Web Annotation Programs

October 2002

D. Grant Grant Campbell

This paper examines the implications of annotation programs, such as Annotea, for the development of the Dublin Core. Annotation programs enable multiple users, situated far apart, to comment on a Web-mounted document, even when they lack write access, through the use of annotation servers. Early indications suggest that the Dublin Core can significantly enhance the collaborative authoring ... [Show full abstract] process, especially if the full set of elements is used in a project that involves large numbers of users. However, the task of adapting DC elements and qualifiers for use in annotation threatens to increase the complexity of the scheme, and takes the Dublin Core far from its connections to traditional library cataloguing.

Structured Named Entities in two distinct press corpora: Contemporary Broadcast News and Old Newspap...

July 2012

This paper compares the reference annotation of structured named entities in two corpora with different origins and properties. It addresses two questions linked to such a comparison. On the one hand, what specific issues were raised by reusing the same annotation scheme on a corpus that differs from the first in terms of media and that predates it by more than a century? On the other hand, what ... [Show full abstract] contrasts were observed in the resulting annotations across the two corpora?

ASHG: Automatic Semantic Header Generator

September 2001

Indexing file systems is a powerful means of helping users locate documents, software, and other types of data among large repositories. In environments that contain many di#erent types of data, content indexing requires type-specific processing to extract information e#ectively. Cover page (or Semantic Header) is a portion of each document which should contain information useful in searching for ... [Show full abstract] a document based on a number of commonly used criteria. The information from the semantic header could be used by various indexing schemes to help locate appropriate documents with minimum e#ort. In this paper, we present a model that automatically extracts the secondary or meta-information, and stores it in a Semantic Header which will be used as an index for the document, which will help users in accessing and searching for it.

SOFS : smart object file system for OSD

October 2006

In order to optimize storage of objects in OSD, this paper proposes a smart object file system for OSD:SOFS, it is a file systems container, it can contain several file systems for different applications. At present, it contains two file systems: general object file system and media object file system, one is for small objects such as general document, Web and so on, the other is for large media ... [Show full abstract] objects. The experiment results show that when reading or writing small objects such as common documents, SOFS that is implemented in Linux kernel outperforms ext2 about 10%, and when reading or writing large media object, it outperforms ext2 about 30%.

The impact of relocation on social relationships in a ‘betterment’ area in Transkei∗

August 1986 · Development Southern Africa

P. A. McAllister

Agricultural ‘betterment’ schemes affecting Blacks in rural Southern Africa have frequently involved residential relocation and the reorganization of patterns of land use on the one hand, and negative social and economic effects on the other. In this paper the documented social effects of ‘betterment’ in Ciskei and Transkei are reviewed, with a view to predicting the consequences of the current ... [Show full abstract] implementation of such a scheme in part of the Willowvale district, Transkei. In both respects an attempt is made to relate the social consequences of betterment to (a) the impact of residential relocation and changing patterns of land use on forms of community organization and co‐operation, and (b) the way in which it is experienced by those affected.
