Abstract:Seriation is an exploratory combinatorial data analysis technique to reorder objects into a sequence along a one-dimensional continuum so that it best reveals regularity and patterning among the whole series. Unsupervised learning, using seriation and matrix reordering, allows pattern discovery simultaneously at three information levels: local fragments of relationships, sets of organized local fragments of relationships, and an overall structural pattern. This paper presents an historical overview of seriation and matrix reordering methods, several applications from the following disciplines are included in the retrospective review: archaeology and anthropology; cartography, graphics, and information visualization; sociology and sociometry; psychology and psychometry; ecology; biology and bioinformatics; cellular manufacturing; and operations research.

Our goal is to enhance on-site personalized access and recommendations for cultural heritage. We have designed and implemented the SMARTMUSEUM platform using adaptive and privacy preserving user profiling. The described recommendation system relies on combining a semantics/ontologies based approach with a data mining/statistics based approach. The paper presents the architecture and main methods of the system.

Aps, R., Kell, L.T., Lassen, H., and Liiv, I. 2007. Negotiation framework for Baltic fisheries management: striking the balance of interest. – ICES Journal of Marine Science, 64: 858–861. We explore the issue of balancing stakeholder interests in the translation of science-based advice into agreed management measures. We also analyse the outcome of negotiations within the International Baltic Sea Fishery Commission (IBSFC) for setting the total allowable catch (TAC) for Baltic herring, sprat, cod, and salmon between 1977 and 2004. Given the political and economic pressure inherent in fishery management, IBSFC Contracting Parties, as maximizers of economic value, often set the TAC by unit stock in excess of what was considered sustainable. TACs set in excess of sustainable levels of exploitation (decision-overfishing) reflect the relative importance that negotiating parties attribute to the interests of multiple groups participating in the fishing industry. Such decision-overfishing can be seen as management failure to secure public interest in the long-term health of fish populations. The potential political and social causes of overfishing have to be addressed and removed before measures can be implemented that might reach the goal of sustainable development.

We are witnessing the advent of personal manufacturing, where home users and small and medium enterprises manufacture products locally, at the point and time of need. The impressively fast adoption of these technologies indicates this approach to manufacturing can become a key enabler of the real-time economy of the future. In this paper, we contribute a secure and dependable infrastructure and architecture for that new paradigm. Our solution leverages physical limitations of the computational process into a defense strategy that makes distributed file storage and transfer highly secure. The main idea is to replace asymmetric or public-key encryption functions with an unkeyed, collision, second preimage, and preimage resistant cryptographic hash function. Such a cryptosystem does not have an inverse function H-1. We challenge each block hash against the full hash table to recreate the original message. To illustrate the approach, we describe secured protocols that provide a number of desirable properties during both data storage and streaming. Similar to proof-of-work blockchain consensus algorithms, we parameterized the solution based on the amount of infrastructure available. Experiments show the proposed method can recalculate hashes for a 3-dimensional live matrix of 256 3 at an average of 14 revisions per second, and one revision every 5 minutes for a bigger matrix of 4096 3. The increase in cloud infrastructure cost is insignificant compared to the level of protection offered.
