One of the aims of this report has been to make an inventory of the building trade market to see which document handling systems that are available. The secondary aim was to document the users´ demands on the systems and other demands such as quality assurance. After this, the document handling systems Byggnet and Lotus Notes, which are rather complex systems, have been analysed. Finally a recommendation has been made. In the inventory of the marketthe internet has been used because it is there the latest information can be found.

The purpose of this essay was to study the implementation of a policy document, which concerns questions of integration, in a municipality with an indirect government. I have especially focused on issues regarding how civil servants describe the usage of a specific policy document and to what extent their autonomy and the indirect government have had an impact on implementation, and to what extent signals from surrounding institutions have had an impact on the creation of the policy document. The study was based on qualitative interviews in groups, pairs and with single individuals with twenty-seven civil servants and politicians working with issues concerning the specific policy document.One of the conclusions of my study is that the reason for producing the document in the first place is that the municipality as an organization strives to acquire a sense of legitimacy. The intentions of the document have only partly been implemented by the civil servants and politicians, since the document is not used in their daily work. Here, their autonomy has played an important part, as the choice to not use the document is the servants' own.

In this thesis we compare how different strategies in choosing attribute values affects junk mail filtering. We used two different variants of a naïve Bayesian junk mail filter. The first variant classified an e-mail by comparing it to a feature vector containing all attribute values that were found in junk mails in the part of the e-mail collection we used for training the filter. The second variant compared an e-mail to a feature vector that consisted of the attributes that was found in ten or more junk mails in the part of the e-mail collection we used for training the filter. We used an e-mail collection that consisted of 300 e-mails, 210 of these were junk mails and 90 were legitimate e-mails.

SMTP, the current protocol for sending electronic mail (e-mail) over the Internet, has for many years suffered from several problems and limitations. When it was designed, well over twenty years ago, the requirements for e-mail were very different from those of today. A message was a text message in English, and both user and machine were explicitly named in the address. The protocol was not designed to transfer other types of messages, and no mechanism was included to verify the identity of the sender.In order to solve these shortcomings, a new e-mail protocol needs to be defined. This report specifies a basis for what such a protocol may look like.

This master thesis deals with events, dynamics and problems of mediated information seeking within the context of a new information service called "Book a librarian". The study, based on a survey and interviews both in academic and public libraries and participant observations in academic libraries, has its theoretical base in the cognitive theory of information retrieval interaction. The cognitive view is used to throw light upon the need of an ongoing dialogue during the session in order to detect the information needs of the user and to conduct a successful retrieval of information. The communicative interaction is seen as threepart interaction between the intermediary, the user and the information system, where the current cognitive states of all three participants are involved. The study shows that the cognitive obstacles for a successful mediation and information retrieval are mostly connected to participants current knowledge of the subject and of the retrieval techniques.

As the information society becomes increasingly flooded with digital images, the need for efficient image retrieval systems increases as well. To handle the vast amounts of data involved, the indexing process needs to be run automatically, using content-based descriptors extracted directly from the digital image, such as colour composition, shape and texture features. These content-based image retrieval systems are often slow and cumbersome, and can appear confusing to an ordinary user who does not understand the underlying mechanisms. One step towards more efficient and user-friendly retrieval systems might be to adjust the weight placed on various descriptors depending on which image category is being searched for. The results of this thesis show that certain categories of digital images would benefit from having extra weight assigned to colour, texture or shape features when searching for images of that category..

The purpose of this paper is to examine the three main translation methods used in experimental Cross-language Information Retrieval CLIR research today, namely translation using either machine-readable dictionaries, machine translation systems or corpus-based methods. Working notes from research groups participating in the Text Retrieval Conference TREC and the Cross-Language Evaluation Forum CLEF between 1997 and 2000 have provided the main source material used to discuss the possible advantages and drawbacks that each method presents. It appears that all three approaches have their pros and cons, and because the different researchers tend to favour their own chosen method, it is not possible to establish a "winner approach" to CLIR translation by studying the working notes alone. One should remember however that the present interest in cross-language-applications of information retrieval has arisen as late as in the 1990s, and thus the research is yet in its early stages. The methods discussed in this paper may well be improved, or perhaps replaced by others in the future..

Att företag sänder delar, eller majoriteten, av sin reklam genom e-mail är något som blivit allt vanligare de senaste åren. Fördelarna med e-mailreklam är många, det ger till exempel företagen möjligheten att på ett mycket kostnadseffektivt sätt sända antingen stora utskick av liknande meddelande till breda kundgrupper, eller att personifiera och rikta erbjudandena speciellt mot en mindre grupp. Positivt med reklam genom e-mail är dessutom att det ger mottagaren möjlighet att direkt ge respons. Ämnet är dock fortfarande att betrakta som relativt nytt och även om fördelarna är många så är det också att förknippa med stora problem, exempelvis spam. Syftet med detta arbete har varit att öka kunskapen om hur konsumentföretag använder sig av e-mail i sin reklamstrategi..

The aim of this thesis is to investigate librarians? experiences and opinions about a system for fiction retrieval based on the subject headings list Att indexera skönlitteratur. I want to know if librarians experience that subject headings searches for fiction literature are a good working tool, if there according to librarians are other resources and means that makes fiction available and searchable, and how they estimate the possibility of non-professionals to use subject headings for fiction retrieval. Six librarians at public libraries in Göteborg where interviewed. The interviews dealt with their work with fiction literature, their experiences of subject headings as a fiction retrieval tool, and with their contacts with patrons.

The work with this paper began with a belief that the permission aspect plays acrucial part when it comes to consumers perceptions of marketing through E-mailand SMS - especially when it comes to advertising that is received through a devicethat the consumer has a strong personal relationship with. The questions to beinvestigated was: "How do users of computers and mobile phones feel aboutadvertisement received through E-mail and SMS?" and "In what way does the usersrelationship to the computer or mobile phone affect how they feel about theadvertisement?". The study was based on a questionnaire as well as an analysis of theresponses in combination with previous research on the subject.The results showed that the majority of the respondents from this papers surveywere found to have a negative attitude toward advertisement through both E-mail andSMS. However, the respondents turned out to have a slightly higher tolerance foradvertisement through E-mail than towards advertisement through SMS.

The aim of this thesis was to evaluate the music downloading service Musikwebb regarding its indexing and retrieval effectiveness. This was done by performing various kinds of search in the system. The outcome of these searches were then analysed according to the criteria specificity, precision, recall, exclusivity and authority control. The study showed that Musikwebb had several flaws regarding its retrieval effectiveness. The most prominent cases were the criteria exclusivity and specificity.

This thesis is developed by Posten Åland AB in order to simplify the work of agency staff when distributing mail in rural areas. In my thesis I have developed an application to help automotive mail dispensers. The need for such an application exists, especially during the summer but at other times when ordinary dividend cannot run his route. With the help of a PDA and a GPS the mail dispenser should see where the next stop is and what is to be delivered thereThere already was a directory of mailboxes and the addressees and the coordinates of the mailboxes. Using this, I will implement functionality to retrieve a specific route and plot those coordinates on the map..

We have produced a process mapping and from there developed a document management plan for the research service at the Labour Movement Archives and Library (ARAB) in Stockholm, Sweden. The project was conducted during five weeks in the spring of 2011 at ARAB and the resulting classification structure and document plan has been formulated and presented to the staff at a seminar. We found that the institution in some cases were suffering from an inadequate documentation in a number of the identified processes, and also in their records management and archiving. In this additional memorandum follows an analyzing discussion of activity-based document- and archive management, e-archives and process mapping. We have accordingly tried to standardize the process of research services and contribute to a more adequate document management within the institution.

The purpose of this thesis is to evaluate two pearl growing methods in ISI Web of Science. The methods tested are Find Related Records FRR, an automatic service that uses bibliographic coupling, and Author Keywords AK, where searches are performed using the two first keywords from this field. Both search methods were used on twenty initial documents and the first twenty hits were evaluated for relevance using a binary scale 0,1. The relevance criteria were based on specific information needs connected to every initial document. The measures used to evaluate the effectiveness of the search methods were Precision at DCV=10, P10, and Uninterpolated Average Precision AP.

This thesis discusses main problems associated with dictionary-based Cross-Language Information Retrieval as lexical and translational ambiguity of query terms, translation of compounds and phrases, dictionary limitation. The purpose of the study is to investigate how query structure influences the effectiveness of CLIR regarding performance of three query types: original query, unstructured query and structured query. Query structuring refers to the application of #syn-operator to group query terms. The study comprises an experiment that was performed in the InQuery IR system with TrecUta database that contains 550,000 news articles from different American newspapers. 24 topics were used for the experiment.
