Abstract: Plötzlich diese Übersicht. Milliarden von Seiten, in Sekundenbruchteilen durchsucht, als Trefferliste sauber angezeigt, mit der größten Selbstverständlichkeit sortiert nach Rang und Namen. Google bestimmt die Routinen des Alltags und ist dennoch nicht die Suchmaschine schlechthin. Auch außerhalb des World Wide Web gibt es zahllose, technisch hochgerüstete Prozeduren des Suchens. Die gegenwärtige Selbstverständlichkeit der einen Suchmaschine läßt leicht übersehen, daß Suchmaschinen einen Interessenkonflikt induzieren zwischen jenen, die sie einsetzen wollen, und jenen, auf die sie angesetzt werden. Ihr prekärer Status im Spannungsfeld zwischen Übersicht und Überwachung wird verdrängt. Anhand von vier Fallstudien zeigt David Gugerli die Entwicklung der Suchmaschine auf, von den frühen Fernseh-Ratespielen, von Robert Lembkes Unterhaltungsshow »Was bin ich?«, über Eduard Zimmermanns Fahndungssendung »Aktenzeichen XY« und Horst Herolds »Kybernetik der Polizei« bis zu der von Ted Codd ausgehenden Entwicklung der relationalen Datenbank. Während Lembke auf die Feststellung von Normalität ausgerichtet war, suchte Zimmermann die Devianz, Herold die Muster und Codd die allgemeingültige Such- und Abfragesprache für in Form gebrachte Wissensbestände, die man seit Mitte der sechziger Jahre Datenbanken nennt. »Die Geschichte der Suchmaschine ist eine eminent politische. Mit Suchmaschinen lassen sich Hoffnungen auf Fundamentaldemokratisierung und informationelle Emanzipation ebenso verbinden wie Horrorvisionen eines Orwellschen Überwachungsstaats, der über ein technokratisches Wissensmonopol verfügt.«

22Prasad, A.R.D. ; Madalli, D.P.: Faceted infrastructure for semantic digital libraries.
In: Library review. 57(2008) no.3, S.225 - 234.
Abstract: Purpose - The paper aims to argue that digital library retrieval should be based on semantic representations and propose a semantic infrastructure for digital libraries. Design/methodology/approach - The approach taken is formal model based on subject representation for digital libraries. Findings - Search engines and search techniques have fallen short of user expectations as they do not give context based retrieval. Deploying semantic web technologies would lead to efficient and more precise representation of digital library content and hence better retrieval. Though digital libraries often have metadata of information resources which can be accessed through OAI-PMH, much remains to be accomplished in making digital libraries semantic web compliant. This paper presents a semantic infrastructure for digital libraries, that will go a long way in providing them and web based information services with products highly customised to users needs. Research limitations/implications - Here only a model for semantic infrastructure is proposed. This model is proposed after studying current user-centric, top-down models adopted in digital library service architectures. Originality/value - This paper gives a generic model for building semantic infrastructure for digital libraries. Faceted ontologies for digital libraries is just one approach. But the same may be adopted by groups working with different approaches in building ontologies to realise efficient retrieval in digital libraries.

23Petrelli, D.: On the role of user-centred evaluation in the advancement of interactive information retrieval.
In: Information processing and management. 44(2008) no.1, S.22-38.
Abstract: This paper discusses the role of user-centred evaluations as an essential method for researching interactive information retrieval. It draws mainly on the work carried out during the Clarity Project where different user-centred evaluations were run during the lifecycle of a cross-language information retrieval system. The iterative testing was not only instrumental to the development of a usable system, but it enhanced our knowledge of the potential, impact, and actual use of cross-language information retrieval technology. Indeed the role of the user evaluation was dual: by testing a specific prototype it was possible to gain a micro-view and assess the effectiveness of each component of the complex system; by cumulating the result of all the evaluations (in total 43 people were involved) it was possible to build a macro-view of how cross-language retrieval would impact on users and their tasks. By showing the richness of results that can be acquired, this paper aims at stimulating researchers into considering user-centred evaluations as a flexible, adaptable and comprehensive technique for investigating non-traditional information access systems.

24Petrelli, D. ; Levin, S. ; Beaulieu, M. ; Sanderson, M.: Which user interaction for cross-language information retrieval? : design issues and reflections.
In: Journal of the American Society for Information Science and Technology. 57(2006) no.5, S.709-722.
Abstract: A novel and complex form of information access is cross-language information retrieval: searching for texts written in foreign languages based on native language queries. Although the underlying technology for achieving such a search is relatively well understood, the appropriate interface design is not. The authors present three user evaluations undertaken during the iterative design of Clarity, a cross-language retrieval system for lowdensity languages, and shows how the user-interaction design evolved depending on the results of usability tests. The first test was instrumental to identify weaknesses in both functionalities and interface; the second was run to determine if query translation should be shown or not; the final was a global assessment and focused on user satisfaction criteria. Lessons were learned at every stage of the process leading to a much more informed view of what a cross-language retrieval system should offer to users.

In: Journal of the American Society for Information Science and Technology. 57(2006) no.4, S.493-500.
Abstract: In recent years, many evaluations of Web sites have been conducted, and relevant researches have also been carried out in academic circles. Correspondence analysis is introduced in this paper to evaluate university library Web sites through building a correspondence analysis model. This paper gives suggestions as to how to construct university library Web sites based on analysis and summary of evaluation results, in a bid to strengthen the construction of university library Web sites.
26Castelli, D.: Digital libraries of the future - and the role of libraries.
In: Library hi tech. 24(2006) no.4, S.496-503.
Abstract: Purpose - The purpose of this article is to introduce the digital libraries of the future, their enabling technologies and their organisational models. Design/methodology/approach - The paper first discusses the requirements for the digital libraries of the future, then presents the DILIGENT infrastructure as a technological response to these requirements and, finally, it discusses the role that libraries can play in the organisational framework envisioned by DILIGENT. Findings - Digital libraries of the future will give access to a large variety of multimedia and multi-type documents created by integrating content from many different heterogeneous sources that range from repositories of text, images, and audio-video, to scientific data archives, and databases. The digital library will provide a seamless environment where the co-operative access, filtering, manipulation, generation, and preservation of these documents will be supported as a continuous cycle. Users of the library will be both consumers and producers of information, either by themselves or in collaborations with other users. Policy ensuring mechanisms will guarantee that the information produced is visible only to those who have the appropriate rights to access it. The realisation of these new digital libraries requires both the provision of a new technology and a change in the role played by the libraries in the information access-production cycle. Practical implications - Digital libraries of the future will be core instruments for serving a large class of applications, especially in the research field. Originality/value - The paper briefly introduces one of the most innovative technologies for digital libraries, and it discusses how it contributes to the realisation of a novel digital libraries scenario.

27Petrelli, D. ; Beaulieu, M. ; Sanderson, M. ; Demetriou, G. ; Herring, P. ; Hansen, P.: Observing users, designing clarity : a case study an the user-centered design of a cross-language information retrieval system.
In: Journal of the American Society for Information Science and Technology. 55(2004) no.10, S.923-934.
Abstract: This report presents a case study of the development of an interface for a novel and complex form of document retrieval: searching for texts written in foreign languages based on native language queries. Although the underlying technology for achieving such a search is relatively weIl understood, the appropriate interface design is not. A study involving users from the beginning of the design process is described, and it covers initial examination of user needs and tasks, preliminary design and testing of interface components, building, testing, and refining the interface, and, finally, conducting usability tests of the system. Lessons are learned at every stage of the process, leading to a much more informed view of how such an interface should be built.

In: Challenges in knowledge representation and organization for the 21st century: Integration of knowledge across boundaries. Proceedings of the 7th ISKO International Conference Granada, Spain, July 10-13, 2002. Ed.: M. López-Huertas. Würzburg : Ergon Verlag, 2003. S.113-119.
(Advances in knowledge organization; vol.8)
Abstract: The present work deals with building a computational model for maintenance of a classification schedule. It has been hypothesized that the analytico-synthetic approach is quite amenable to the tools and techniques of Artificial Intelligence. To achieve the objective of building an automatic system for management of classification schemes, 'Vyasa', has been developed using Al tools and techniques. 1. Introduction The present work is a sequel to the earlier work, where the application of Artificial Intelligence tools and techniques were used in the verbal plane i.e. subject indexing (Aptagiri, et al., 1995; Prasad, 1993) and later extended to notational plane where the system could assign automatically the class numbers to given expressive titles (Panigrahi, 1996). The present paper is based an the work carried out to update the 7th edition of Colon Classification (Madalli, 2000).
29Li, D.: Knowledge representation and discovery based on linguistic atoms.
In: Knowledge-based systems. 10(1998) no.7, S.431-440.
Abstract: Describes a new concept of linguistic atoms with 3 digital characteristics: expected value Ex, entropy En, and deviation D. The mathematical description has effectively integrated the fuzziness and randomness of linguistic terms in a unified way. Develops a method of knowledge representation in KDD, which bridges the gap between quantitative and qualitative knowledge. Mapping between quantities and qualities becomes much easier and interchangeable. In order to discover generalised knowledge from a database, uses virtual linguistic terms and cloud transfer for the auto-generation of concept hierarchies to attributes. Predicitve data mining with the cloud model is given for implementation. Illustrates the advantages of this linguistic model in KDD
