Using the correlation of the GHZ triplet states, a broadcasting multiple blind signature scheme is proposed. Different from classical multiple signature and current quantum signature schemes, which could only deliver either multiple signature or unconditional security, our scheme guarantees both by adopting quantum key preparation, quantum encryption algorithm and quantum entanglement. Our proposed scheme has the properties of multiple signature, blindness, non-disavowal, non-forgery and traceability. To the best of our knowledge, we are the first to propose the broadcasting multiple blind signature of quantum cryptography.

Exchanging user information between multiple sources can potentially bring many benefits that enhance the user experience in software applications. Richer and more dynamic user models can be constructed allowing more tailoring of content and services to the specific needs of individual users. However, providing effective interoperability is a complex challenge as there can be significant heterogeneity between user models. Current generic approaches and tools offer insufficient support for the complex domain-specific nature of many user model interoperability tasks. This paper presents a comparative study of the FUSE domain-aware approach to user model interoperability. This novel approach differs from existing generic approaches by incorporating domain knowledge in new processes and tools to support complex user model interoperability tasks in multiple overlapping domains. The FUSE approach is described and compared to existing state of the art approaches using a consistent set of key issues in user model interoperability.

Ontology matching and mapping is of critical importance to effective consumption of distributed and heterogeneous data-sets in today's Web of data. Since 2004 the Ontology Alignment Evaluation Initiative (OAEI) provides a number of complex challenges to evaluate the performance of the increasing number of matching tools and methods. This leads to the question how the individual OAEI challenges and the individual alignment results can be documented best for effective online consumption, management and further analysis. In this paper, we argue that the current documentation of alignment creation lifecycle aspects within OAEI would benefit from more formal model support. In this paper we present a case study to show how our ontology-based meta-data model for ontology mapping reuse (OM2R) can be applied for the OAEI to document alignment challenges and some quantification on the likely benefits in terms of helping challenge administrators and participants create consistent documentation in terms of high correctness and less inconsistent statements as well as results that are explicit, predictable and easy to interpret.

One to one correspondences between entities are not always sufficient to describe the true relationship between related entities in diverse ontologies, and complex correspondences are needed instead. We demonstrate the types of complex correspondence occurring between two LOD sources and compare techniques for discovering these complex correspondences.

Despite the recent interest in extending Adaptive Hypermedia beyond the closed corpus domain and into the open corpus world of the web, many current approaches are limited by their reliance on closed metadata model repositories. The need to produce large quantities of high quality metadata is an expensive task which results in silos of high quality metadata. These silos are often underutilized due to the proprietary nature of the content described by the metadata and the perceived value of the metadata itself. Meanwhile, the Linked Open data movement is promoting a pragmatic approach to exposing, sharing and connecting pieces of machine-readable data and knowledge on the WWW using an agreed set of best practices. In this paper we identify the potential issues that arise from building personalization systems based on Linked Open data.

A key advantage of Adaptive Hypermedia Systems (AHS) is their ability to re-sequence and reintegrate content to satisfy particular user needs. However, this can require large volumes of content, with appropriate granularities and suitable meta-data descriptions. This represents a major impediment to the mainstream adoption of Adaptive Hypermedia. Open Adaptive Hypermedia systems have addressed this challenge by leveraging open corpus content available on the World Wide Web. However, the full reuse potential of such content is yet to be leveraged. Open corpus content is today still mainly available as only one-size-fits-all document-level information objects. Automatically customizing and right-fitting open corpus content with the aim of improving its amenability to reuse would enable AHS to more effectively utilise these resources. This paper presents a novel architecture and service called Slicepedia, which processes open corpus resources for reuse within AHS. The aim of this service is to improve the reuse of open corpus content by right-fitting it to the specific content requirements of individual systems. Complementary techniques from Information Retrieval, Content Fragmentation, Information Extraction and Semantic Web are leveraged to convert the original resources into information objects called slices. The service has been applied in an authentic language elearning scenario to validate the quality of the slicing and reuse. A user trial, involving language learners, was also conducted. The evidence clearly shows that the reuse of open corpus content in AHS is improved by this approach, with minimal decrease in the quality of the original content harvested. Copyright 2012 ACM.
