Abstract
Purpose
The overwhelming speed and scale of digital media production greatly outpace conventional indexing methods by humans. The management of Big Data for e-library speech resources requires an automated metadata solution. The paper aims to discuss these issues.
Design/methodology/approach
A conceptual model called semantic ontologies for multimedia indexing (SOMI) allows for assembly of the speech objects, encapsulation of semantic associations between phonic units and the definition of indexing techniques designed to invoke and maximize the semantic ontologies for indexing. A literature review and architectural overview are followed by evaluation techniques and a conclusion.
Findings
This approach is only possible because of recent innovations in automated speech recognition. The introduction of semantic keyword spotting allows for indexing models that disambiguate and prioritize meaning using probability algorithms within a word confusion network. By the use of AI error-training procedures, optimization is sought for each index item.
Research limitations/implications
Validation and implementation of this approach within the field of digital libraries still remain under development, but rapid developments in technology and research show rich conceptual promise for automated speech indexing.
Practical implications
The SOMI process has been preliminarily tested, showing that hybrid semantic-ontological approaches produce better accuracy than semantic automation alone.
Social implications
Even as testing proceeds on recorded conference talks at the University of Tebessa (Algeria), other digital archives can look toward similar indexing. This will mean greater access to sound file metadata.
Originality/value
Huge masses of spoken data, unmanageable for a human indexer, can prospectively find semantically sorted and prioritized indexing – not transcription, but generated metadata – automatically, quickly and accurately.

Abstract
Purpose
The purpose of this article is to present a conceptual model for the design of a scholarly web portal at the University of Tébessa, with which it is hoped that scholarly work stations that combine local and remote holdings, tools and documents will be created. Today, with access to enormous quantities of information facilitated by the web, boundaries between remote and local source documents become invisible. This is of extreme interest for libraries in Algeria, whose local holdings are very limited.
Design/methodology/approach
An outlined conceptual model of library portal architecture, with ontological classifications and relationships is presented. The model comes from applying literature reviews to the needs and specifications of the authors and leads to a detailed breakdown of the planning and implementation process.
Findings
Three findings in particular are worth noting. First, the contribution of web services to the seamless utility of a scholarly portal is indispensable: interoperable features, formats and protocols can be carefully customized. Second, the conceptual model assists not only in visualization but in implementation phases of the process from assessment of user needs and behaviors through interface creation and ongoing maintenance. Third, a method for recycling (or “porting”) existing applications in constructing new library services is a key component.
Originality/value
Though this library portal is conceived for an Algerian library, which will ultimately benefit from inclusion in a nationwide network, Réseau Régional Inter Bibliothèques Universitaires (RIBU), the conceptual model may guide anyone interested in aggregating online information resources into a single, seamless terminal.

Abstract
Purpose
This paper aims to identify the factors that have led the USA to be one of the few countries in the world that has seen interlending and document supply continue to increase.
Design/methodology/approach
The factors are identified, reviewed and assessed.
Findings
It was found that the effectiveness of resource sharing facilitated by intra‐ and inter‐state cooperatives using OCLC as a framework is a major factor, others being the improvement in discovery tools, requesting processes and the more recent improvements in the delivery process. Finally, the widespread subsidizing of access and delivery enables cheap or even free use of document supply.
Originality/value
This paper is the only study so far that addresses the current puzzle of US “exceptionalism” for interlending and document supply.

AFTER 17 years continuous service as a LA Council member it seemed strange to me to attend the first council meeting of 1979 as NLW'S reporter.
