    Content-based retrieval of digital music

    One of the advantages of having information in digital form is that it lends itself readily to content-based access. This applies to information stored in any media, though content searching through information stored in a structured database or as text is more developed than content searching through information stored in other media such as music In practice, the most common way to index and provide retrieval on digital music is to use its metadata such as title, performer, etc , as has been done in Napster. My research has lead to the development of a digital music information retrieval system called Ceolaire which can index monophonic music files Music files are analysed for notes on the equal tempering scale, where note changes are observed and recorded as being up (U), down (D) or the same (S) relative to the previous note. These note changes are then indexed in a search engine At query time, notes are generated by a user using a web based interface These notes form the query for the retneval engine. A user is presented with a ranked list of highly scored documents. This thesis explores the building and evaluation of the Ceolaire system

    The digitalization from paper-based to electronic records management results in challenges to preserve material in an authentic form. This paper explores the role in ensuring the authenticity and usability of electronic records in a long term preservation perspective. The discussion is viewed from an information quality perspective that provides a suitable lens to the topic. We identified a number of challenges that government records face, stressing the issue at hand of how to maintain authenticity and usability over a long term perspective. Challenges results from issues around authenticity, usability, the user, volume and heterogeneity and particular the time dimension. We conclude that the fields of record keeping and long term preservation have some clear information quality issues that could benefit from a concerted approach by integrating information quality research into records management. To date this seems to be missing

    A record-keeping approach to managing IoT-data for government agencies

    No full text
    Purpose – Particular attention to the issue of information management will be required to meet the expected growth in IoT-devices and the data they generate. As government agencies start collecting and using such information, they must also deal with the issue of privacy, to comply with laws and regulations. The approach discussed here shows that record-keeping principles may form part of a solution to the issue of managing IoT- data for government agencies. Design/methodology/approach – This study uses the generally accepted record-keeping principles as a basis for a high-level discussion on how IoT-data can be managed. This is followed by a presentation and discussion on how the Norwegian record-keeping standard, Noark, can be extended to highlight practical issues. Findings – Record keeping has principles that are relevant to the management of IoT-data. Further an implementation of the chosen use-cases is possible based on an existing record keeping standard. Record keeping is one of many information science approaches that can manage IoT-data. Research limitations/implications – The main limitations are that the discussion cannot cover all types of IoT-devices, nor can all issues be captured with a limited choice of examples. The results should be seen within the context of the types of devices discussed and limited to the chosen use-cases. However, the level of abstraction used means the results may be applicable to similar scenarios. Originality/value – The approach shows that record-keeping principles may be used as an approach to manage IoT-data. This discussion is useful when compared with other information science approaches, e.g. big-data or semantic Web approaches. The practicalities of a record-keeping approach are also discussed and relevant strengths and weaknesses are showed

    Publishing and using record-keeping structural information in a blockchain

    No full text
    Purpose: To examine the role blockchain can play for record-keeping by exploring what information from a record-keeping system it is possible to publish to a blockchain. A credible approach is presented, followed by a discussion on both benefits and limitations. Design/methodology/approach: The approach is a combination of theorised possibilities verifed with practical software implementation. The basis for the work is relevant record-keeping and blockchain litera- ture. Research limitations/implications: The approach is beneficial where there is a record-keeping standard that has a clearly defined metadata model, and that also makes use of globally unique identifiers. Privacy legislation, e.g., GDPR, may limit the scope of an implementation of the approach. Originality/value: The originality lies in presenting an approach whereby a record-keeping standard is analysed, separating structural and content information in order to publish structural information to a blockchain

    The migration and preservation of six Norwegian municipality record‐keeping systems: Lessons learned

    No full text
    This paper presents a rare insight into the migration of municipality record-keeping databases. The migration of a database for preservation purposes poses several challenges. In particular, our findings show that relevant issues are file-format heterogeneity, collection volume, time and database structure evolution, and deviation from the governing standard. This paper presents and discusses how such issues interfere with an organization's ability to undertake a migration, for preservation purposes, of records from a relational database. The case-study at hand concerns six Norwegian municipality record-keeping databases covering a period from 1999 to 2012. The findings are presented with a discussion on how these issues manifest themselves as a problem for long term preservation. The results discussed here may help an organization and Information Systems (IS) manager to establish a best practice when undertaking a migration project and enable them to avoid some of the pitfalls that were discovered during this project
