In the near future, users will have access to a vast number of digital libraries. For a given information need and limited resources, there is the problem of selecting those libraries which produce an overall optimum answer. This resource discovery problem is additionally complicated by the diversity of the sources, e.g. with respect to media, document formats, indexing methods, database schema...

There exists a large and underutilized resource of archaeological literature, both formal, such as scholarly journals and less formal in the form of ‘grey literature’. In the archaeological domain the vast majority of this literature contains some geo-spatial element as well as the expected temporal information and therefore its ease of discovery would be greatly enhanced were it accessible via...

In the past several years, the number and variety of resources available on the Internet have increased dramatically. With this increase, many new systems have been developed that allow users to search for and access these resources. As these systems begin to interconnect with one another through "information gateways", the conceptual relationships between the systems come into question. Unders...

This paper analyzes the recent development regarding the technology in ad-hoc networks. It compares the different routing protocols and analyses them from architecture design perspective. The comparison includes technical aspects, similarities and missing functionality on each of the protocols. The paper identifies the network resource discovery as missing functionality, and presents a generic ...

Mining data streams has raised a number of research challenges for the data mining community. These challenges include the limitations of computational resources, especially because mining streams of data most likely be done on a mobile device with limited resources. Also due to the continuality of data streams, the algorithm should have only one pass or less over the incoming data elements. In...

Resource Discovery Mechanisms are commonly used to publish and retrieve information about network-available resources. Description Logics are basically a subset of Predicate Logic where expressiveness and computational complexity have been deeply studied. In this paper we present a formal approach to these mechanisms using Description Logics. This is based on a terminological model of the RDM (...

Grid technologies enable the sharing and collaborating of a wide variety of resources. To fully utilize these resources, effective resource discovery mechanisms are necessities. However, the complicated and dynamic characteristics of the grid resources make sharing and discovering them a challenging issue. In this paper, we propose a semantic community approach to assisting the efficient resour...

The Dublin Core Metadata Workshop Series began in 1995 with an invitational workshop which brought together librarians, digital library researchers, content experts, and text-markup experts to promote better discovery standards for electronic resources. The Dublin Core is a 15-element set of descriptors that has emerged from this effort in interdisciplinary and international consensus building....

We present a decision-theory based approach for efficiently sampling information sources in resource-constrained environments, where there is uncertainty regarding source trustworthiness. We exploit diversity among sources to stratify the population into homogeneous subgroups to both minimise redundant sampling and mitigate the effect of certain biases (e.g., source collusion). After presenting...

Arigatoni is a structured multi-layer overlay network providing various services with variable guarantees, and promoting an intermittent participation in the overlay since peers can appear, disappear and organize themselves dynamically. Arigatoni provides fully decentralized, asynchronous and scalable resource discovery; it also provides mechanisms for dealing with an overlay with a dynamic top...
