The aim of this thesis is to, from a feminist point of view, analyse the Universal Decimal Classification UDC, which is an international and widely used Classification system. A number of the larger Classification systems and subject heading lists have during the last decades been placed in the limelight of various gender studies and the systems treatment of women has been criticized. With this examination of the UDC, I dont merely wish to identify shortcomings and advantages with the UDCs way to treat men and women. The UDC is also used as an example of how the gender problem can be identified and interpretated in Classification systems generally. My analysis is performed with a theoretical foundation in feminist science theories about knowledge and norms, together with a linguistic perspective on valuing and emotionally tinged language.

The aim of this thesis is to investigate the understanding of Classification as it is manifested in the discussion of implementing DDC in the BIBSAM-libraries. This is accomplished through the answering of three questions: 1. How does the discussion go about the implementation of DDC in the "Cataloguing practises: a survey of Swedish research libraries" project?2. Have there been any criticism against the project or the implementation and, in that case, what does it say?3.

This master thesis encompasses an inventory and risk Classification of four disused landfills within the municipality of Uppsala, Sweden. The model of the Classification; ?Method of Surveying Contaminated Sites? is developed by the Environmental Protection Agency and can be used as a framework to investigate and describe the environmental damage and the level of risk for each object. The risk Classification model has a rating from 1 to 4, where 1 represents a very high risk while 4 is a small risk. Risk class depends largely on the type of land use that exists on the object, and hence, various benchmarks must be taken into account.

The Swedish Library Classification System, known as the SAB-system, can be viewed as a product of the cultural and social norms and values in Sweden during the time in which it was created and subsequently reviewed. The main purpose of this master?s thesis is to examine the archaeology section J in the SAB-system, in order to observe if values and norms within this discipline had any impact on the Swedish Library Classification system. Our intention is therefore to verify any correspondence between the choice of topics and hierarchical structure of that section, and the values and norms that ruled the Swedish society during the 20th century at large but with particular emphasis to the academic discipline of Archaeology. At the present, Archaeology is often disputed as a value-free interpretive science.

The aim of this thesis is to investigate the opportunities of Classification of web pages. Two Classification systems are compared; a library Classification system traditional and a system that is developed for use on the web new. UDC is chosen to represent the traditional systems, and Yahoo! represents a so called new system. UDC is used by NISS Directory of networked resources, which is a directory that uses the system for organisation of electronic resources. Both systems are analysed from two different perspectives, a multidisciplinary and a timeperspective.

The main purpose of this thesis is to examine what problems may arise when converting class symbols from one Classification scheme to another. In order to fulfill this purpose, a conversion table between parts of the Swedish online-version of the UDC and the Swedish Classification system SAB was constructed. For main classes 0 and 3 every class number from this abridged version of the UDC was converted, whereas for the rest of the main classes only class numbers with fewer than four figures were converted. The conversion table was constructed using the alphabetical index of SAB and different UDC-indexed library catalogues. Various aspects of the conversion table were then analysed using methods mainly devised by the authors themselves, but inspired by lexicography and multilingual thesaurus construction.

The purpose of this Master?s thesis is to study how well the online catalogue of The Music Library of Sweden works when ordinary users are searching for sheet music. The issues studied are: Why do the users fail to find the sheet music they are looking for? Do the users take advantage of the possibilities that the Classification codes of the SAB system offer? If not, why?The source material of the study is 144 comments from a user questionnaire about the online catalogue and, in addition, the search log for one day (513 queries). The comments were sorted into seven groups depending on the type of information need, for example searches for certain instrumentation or genres and problems with spelling.

During 2006 SNVDB (the national road data base for forestry) is being introduced to Holmen Skog. This data base contains all information about Holmen Skogs road systems. The information will then be used in different kinds of optimisation models which only produce correct and reliable results if the input data are of the adequate quality. Today there are reasons to believe that road data is of various qualities. The forest roads are often in a bad condition and have to be improved before a planned harvest. The cost of maintenance and construction of new roads is a large part of the total harvesting cost.

We have carried out a study of a Classification system for the Swedish collection at The Royal Library in Stockholm from 1887. It was printed in 50 copies. The constructor, Bernhard Lundstedt, and his colleagues used it as guidance in lack of a catalogue. We regard it a local Classification system. Little research has been done on old Classification systems, but Francis Miksa points out the importance of examining them.

The thesis examines the view of reality as expressed in the subject structure of the web directory Open Directory Project. This is analyzed in comparison with library Classification systems, regarded as products of the modern library movement. The question is raised whether the world view of the directory, in contrast to the modern Classification systems, can be seen as an expression of postmodernity. Postmodernity is then understood as a radical critique of the modern belief in neutral science and technology as ways of objectively describing the universe of knowledge. The theoretical and methodological approach adopted is borrowed from a poststructuralist reading of Michel Foucault's archaeology and sociologically coloured Classification research.

The main focus of this master?s thesis concerns the relation between subject representation, power and gender. Classification systems and subject heading lists are products of their cultural and social context and some subjects and disciplines are given a greater value than others. Our aim in this thesis is twofold; to discuss and critically analyse the prevailing gender norms that are expressed trough Classification systems and subject heading lists and to examine how they manage to represent gender studies as a multidisciplinary subject in theory as well as in practice. We are also discussing the particular problems with the representation of multidisciplinary subjects in general.

This thesis aims at examining to what extent a few, algorithmically very easily extractable document features can be used to classify electronic documents according to genre. A set of experiments is therefore carried out, using only 11 such simple features in an attempt to classify 84 documents belonging to electronic academic journals into three manually identified genres: table of contents, article, and review. The 11 features are also divided into three sets, containing metrics of words and sentences; punctuation marks; and URL links, respectively. The performance when using these sets of features is then measured with regard to Classification accuracy, using a k-NN classifier, four different values of k (1, 3, 5, 7), and both leave-one-out and 10-fold cross-validation. Best results are achieved when using all three feature sets (i.e.

The Swedish Aviation Safety Authority has decided to standardise a Classification system for reporting deviations found in inspections. The purpose of a Classification system is that similar deviations always should be reported in the same way since this will enable better decisions regarding different risk areas. The inspectors are therefore constrained to use a standardised Classification system and are not free to use their own words when reporting deviations. A hierarchal Classification system with predefined phrases is in aviation referred to as taxonomy. Taxonomy is already in use when reporting accidents and incidents but not when reporting deviations found in inspections.

With numerous applications in both military and civilian life, the demand for accurate 3D models of real world environments increases rapidly. Using an airborne laser scanner for the raw data acquisition and robust methods for data processing, the researchers at the Swedish Defence Research Agency (FOI) in Linköping hope to fully automate the modeling process.The work of this thesis has mainly been focused on three areas: ground estimation, image segmentation and Classification. Procedures have in each of these areas been developed, leading to a new algorithm for ground estimation, a number of segmentation methods as well as a full comparison of various decision values for an object based Classification. The ground estimation algorithm developed has yielded good results compared to the method based on active contours previously elaborated at FOI. The computational effort needed by the new method has been greatly reduced compared to the former, as performance, particularly in urban areas, has been improved.

In this Master we have studied Classification system and alternative arrangements of books in a public library. The public libraries in Sweden use the SAB Classification system. This system was created nearly a hundred years ago in order to suit the librarians and the Swedish society at the time. Today many library users find the system difficult to understand. This and other factors have inspired a number of libraries to arrange books in an alternative and more user-friendly way.
