The following thesis aims to account for and describe the variations of perceptions that public librarians have regarding user-friendliness of the classification systems that are used in Swedish public libraries. How user-friendliness and the classification systems are perceived are examined to understand how the librarians might connect these two together.  The thesis is based on the qualitive research methodology of phenomenography which is a method used in order to create an understanding of the variations of perceptions of a phenomenon. The phenomenographic method is applied by using qualitative interviews. For this study eight public librarians in the Stockholm region have been interviewed. The interviews were conducted in a phenomenographic manner and were set out to be a dialogue between the interviewer and the interviewee. All the libraries in the study are currently working in the SAB classification system. The study shows that there are a variation of different perceptions of user-friendliness and the classification systems. One perception that is found is that SAB is not user-friendly because of the lack of logic within the system and it is a common impression that users find the system confusing. A perception also states that SAB is “a dead system”, referring to the fact that SAB no longer is updated. The perception means that in time, SAB will not be a useable system. Another perception contradicts the first one and says that SAB is a system that users usually understand to a certain degree. The users have the capability to operate within the system to find literature they seek but as they submerge deeper into the systems hierarchy most users usually get confused. Another perception is that the connection between user-friendliness and classification systems is not of importance. This perception proclaims that user-friendliness can be achieved by working with signage and shelf placement instead. The study also shows that there is a gap between how the librarians perceive the classification systems and how they imagine their users perceiving them. This is shown in the lack of dialogue between users and librarians. A common perception among the librarians is that they have what they call a “home blindness” concerning the classification systems. This statement is made referring to the fact that librarians work within these systems day by day and easily forgets to reflect on the difficulties that a first-time user might face as they try to understand the systems.

Semantic Web und Linked Data sind in aller Munde. Nach fast einem Jahrzehnt der Entwicklung der Technologien und Erforschung der Möglichkeiten des Semantic Webs rücken nun die Daten in den Mittelpunk, denn ohne diese wäre das Semantic Web nicht mehr als ein theoretisches Konstrukt. Fast wie das World Wide Web ohne Websites. Bibliotheken besitzen mit Normdaten (PND, SWD) und Titelaufnahmen eine Fülle Daten, die sich zur Befüllung des Semantic Web eignen und teilweise bereits für das Semantic Web aufbereitet und zur Nutzung freigegeben wurden. Die Universitätsbibliothek Mannheim hat sich in zwei verschiedenen Projekten mit der Nutzung solcher Daten befasst – allerdings standen diese zu diesem Zeitpunkt noch nicht als Linked Data zur Verfügung. In einem Projekt ging es um die automatische Erschließung von Publikationen auf der Basis von Abstracts, im anderen Projekt um die automatische Klassifikation von Publikationen auf der Basis von Titeldaten. Im Rahmen dieses Beitrags stellen wir die Ergebnisse der Projekte kurz vor, möchten aber im Schwerpunkt auf einen Nebenaspekt eingehen, der sich erst im Laufe dieser Projekte herauskristallisiert hat: Wie kann man die gewonnenen Ergebnisse dauerhaft und sinnvoll zur Nachnutzung durch Dritte präsentieren? Soviel vorweg: Beide Verfahren können und wollen einen Bibliothekar nicht ersetzen. Die Einsatzmöglichkeiten der generierten Daten sind vielfältig. Konkrete Einsätze, zum Beispiel das Einspielen in einen Verbundkatalog, sind aber aufgrund der Qualität und mangelnden Kontrolle der Daten umstritten. Die Bereitstellung dieser Daten als Linked Data im Semantic Web ist da eine naheliegende Lösung – jeder, der die Ergebnisse nachnutzen möchte, kann das tun, ohne dass ein bestehender Datenbestand damit kompromittiert werden könnte. Diese Herangehensweise wirft aber neue Fragen auf, nicht zuletzt auch nach der Identifizierbarkeit der Ursprungsdaten über URIs, wenn diese (noch) nicht als Linked Data zur Verfügung stehen. Daneben erfordert die Bereitstellung von Ergebnisdaten aber auch weitere Maßnahmen, die über die gängige Praxis von Linked Data hinaus gehen: Die Bereitstellung von Zusatzinformationen, die die Quelle und das Zustandekommen dieser Daten näher beschreiben (Provenienzinformationen), aber auch weitere Informationen, die über das zugrunde liegende Metadatenschema meist hinausgehen, wie Konfidenzwerte im Falle eines automatischen Verfahrens der Datenerzeugung. Dazu präsentieren wir Ansätze auf Basis von RDF Reification und Named Graphs und schildern die aktuellen Entwicklungen auf diesem Gebiet, wie sie zum Beispiel in der Provenance Incubator Group des W3C und in Arbeitsgruppen der Dublin Core Metadaten-Initiative diskutiert werden.

Syftet med denna studie är att beskriva hur judendom och judar klassificeras i tre bibliografiska klassifikationssystem som används på svenska bibliotek. De valda systemen är Dewey Decimal klassifikationssystemet (DDK), Klassifikationssystemet för svenska bibliotek (SAB) och Judiska biblioteks klassifikationssystem (Stockholmssystemet). Hermeneutikens teorier används som teoretisk utgångspunkt i kombination med Hope A. Olsons teori om makten att namnge och Broughton och Lomas modell om klassifikation av religion. Detta används för att analysera resultatet av studien. Det empiriska materialet insamlades genom en kvalitativ textstudie, vilket innebar en närläsning utifrån ett kodningsschema. Resultatet tematiserades i sex kategorier och analyserade utifrån de ovannämnda teorierna. DDK- och SAB-systemet representerar judar som en minoritet och judendom som religion tilldelas lite utrymme i klassifikationssystemen. I Stockholmssystemet är judendom och judar normen och den judiska tideräkningen och namnvarianter premieras, till skillnad från de övriga systemen. DDK-systemet presenterar judendom och judar med mångfald, Stockholmssystemet i lite mindre utsträckning och SAB-systemet utan någon mångfald. / The aim of the study is to describe how Judaism and Jews are classified in the bibliographic classification systems that are used in Swedish libraries. The chosen systems are the Dewey Decimal Classification System (DDC), Classification System for Swedish Libraries (SAB) and the Jewish Library’s Classification system (The Stockholm System). Hermeneutics is the theoretical basis in combination with Hope A. Olson’s theory of the power to name and Broughton and Lomas model of the classification of religion. This is used to analyze the results of the study. The empirical material was gathered using a qualitative text study, which entailed a close reading with a coding schedule. The result was thematized into six categories and analyzed with the aforementioned theories. The DDC and SAB systems represent Jews as a minority and Judaism as a religion is given little space in the classification systems. Judaism and Jews are the norm in the Stockholm system and Jewish chronology and name variants are promoted. The DDC system presents Judaism and Jews with diversity, the Stockholm system less so and the SAB system contains no diversity.

I takt med att byggsektorn övergår till digital informationsmodellering av sina projekt ökar även behovet för att samordna och effektivisera hanteringen av denna information. Ett gemensamt språk i form av ett branschgemensamt klassifikationssystem kan leda till miljardbesparingar. Inom kalkyleringen är det viktigt att rätt informationshantering sker för att bidra till att en så noggrann kalkyl som möjligt kan utföras. Syftet med studien är att undersöka hur de tre olika systemen, BSAB 83, BSAB 96 och CoClass, skiljer sig och ställa de i kontrast mot varandra för att påvisa dessa skillnader. Målet är att studien skall kunna ligga till grund för hur ÅF kan skapa kalkyler klassade enligt CoClass. För att uppnå rapportens syfte och besvara frågeställningar har granskningen bestått av litteraturstudier, intervjuer, en komparativ studie och en fallstudie. Dessa metoder har bidragit i sin tur att resultatet av studien visade att ÅF skulle kunna övergå till CoClass på ett effektivt sätt. Vid jämförelsen mellan systemen har det visat sig att CoClass är ett mer omfattande och ett heltäckande system som struktureras på ett annat vis i motsats till de tidigare klassifikationssystemen. Med hänsyn till studiens resultat kan en kalkylstruktur enligt CoClass implementeras i ÅF:s nuvarande arbetssätt, där färdiga recept för byggdelar fortfarande kan användas. Rekommendationen är att betrakta komponent-tabellen som likvärdig till produktionsresultatet vid kalkylarbete med CoClass struktur i MAP. Detta hade i det långa loppet varit en sund strategi, både ekonomiskt men främst tidsmässigt. / As the construction industry shifts to digital information modeling of its projects, the need to coordinate and improve the efficiency of the management of this information increases. A common language in the form of an industry-wide classification system could lead to billions in savings annually. In the calculation, it is important that the correct information management is included in order to provide the most accurate calculation possible. The aim of this study is to examine how the three different systems, BSAB 83, BSAB 96 and CoClass, differ and stand in contrast to each other to highlight and demonstrate such differences. The purpose of the study is that it should be used as a basis for how ÅF can create classified calculations with CoClass. To achieve the aim of the report and answer the research questions, the examination consisted of literature studies, interviews, a comparative study and a case study. These methods contributed to the following result: ÅF could effectively transfer to the CoClass system. When comparing the systems, it has been shown that CoClass is a more extensive and comprehensive system structured in a different way as opposed to the previous classification systems. Based on the results of the study, a calculation structure according to CoClass can be implemented in ÅF's current working methods, where ready-made recipe for building components can still be used. The recommendation is to consider the component table as equivalent to the production result in the calculation work with CoClass structure in the MAP. In the long run, this would have been an efficient strategy, both economically and primarily less time-consuming.

Introduction. This thesis is set in the field of critical knowledge organization and indigenous knowledge organi- zation. Building on the theory of domain analysis I chose the Saami Library in Sweden as the domain for this thesis. The purpose was to identify the structures of power affecting how the lives and experiences of the Saami people are represented in the library catalogue and in the classification systems used, and to examine the views on knowledge expressed in the classification systems. Theory and method. This thesis builds upon the writings on deconstruction. I seek to deconstruct the cata- logue and the classification system using tools derived from the writings of Jacques Derrida. Analysis. Nine posts from the catalogue, and the classification codes entered there were analysed. Emphasis was put on analysing the DDC classification as this is the primary classification system used. Results. From analysing the classifications and the catalogue posts I found that the representations of the Saami experiences varied depending on which subject class the book belonged to. A majority of the posts analysed were classified as social sciences in DDC whereas the classifications were more varied in the Swedish SAB- system. Conclusion. Two structures have been identified. The first structure places the Saami experiences as some- thing that is other, in relation to which the mainstream is defined. The second structure places the Saami experi- ences as part of a diversity, separate from the unity of the mainstream society. This structure only acknowledges the existence of diversity if this means that the position of the unity is strengthened. Concerning the second purpose of the thesis I find that a western knowledge perspective has got a hegemonic position in the DDC, which means that other knowledge systems such as indigenous knowledge is not seen as such but as something only related to a specific group. This is a two years master’s thesis in Library and Information Science.
