AXMEDIS Programme and Publication Tools Integration with Workflow-Enabled Communication and Process Control
This paper presents the AXMEDIS Programme and Publications (P&P) tools as supported by workflow (WF) integration enabling communication and control in a way that is designed to empower the user to locate digital contents of interest over the AXMEDIS P2P network and to manage and assign the distributions as required. These communications support a large set of interconnections between different sections of the AXMEDIS framework to enable automated processing and integration of digital contents. Following a brief introduction to the overall AXMEDIS framework, this paper presents the functionalities and features of the Programme and Publication (P&P) tools, discusses each individual component, including the P&P Editor and P&P Engine set in the context of the architecture for workflow integration and control for P&P tools within the AXMEDIS Framework

Music Manuscript Tracing
This paper presents an ongoing project working on an optical handwritten music manuscript recognition system. A brief background of Optical Music Recognition (OMR) is presented, together with a discussion on some of the main obstacles in this domain. An earlier OMR prototype for printed music scores is described, with illustrations of the low-level pre-processing and segmentation routines, followed by a discussion on its limitations for handwritten manuscripts processing, which led to the development of a stroke-based segmentation approach using mathematical morphology. The pre-processing sub-systems consist of a list of automated processes, including thresholding, deskewing, basic layout analysis and general normalization parameters such as the stave line thickness and spacing. High-level domain knowledge enhancements, output format and future directions are outlined.

Recognition and reconstruction of primitives in music scores
Abstract Music recognition bears similarities and differences to OCR. In this paper we identify some of the problems peculiar to musical scores, and propose an approach which succeeds in a wide range of non-trivial cases. The composer customarily proceeds by writing notes, then stems, beams, ties and slurs — we have inverted this approach by segmenting and then subsegmenting scores to recapture the component parts of symbols. In this paper, we concentrate on the strategy of recognizing sub-segmented primitives, and the reassembly process which reconstructs low level graphical primitives back to musical symbols. The sub-segmentation process proves to be worthwhile, since many primitives complement each other and high level musical theory can be employed to enhance the recognition process.

Automated Paper-Based Watermark Extraction and Processing
The boom of digital market and rapid expansion and demand of digital content consumption have many requirements for automated content processing, cataloguing, authenticating, indexing, etc.. Digital watermarking and fingerprinting techniques are being explored to authenticate and detect features in digital objects. This is similar to the analogue paper-based watermarking technique that was invented in the 13th century in Italy for the identification of the workers. This paper presents a framework for the digitisation, extraction and graphical representation of paper-based watermark designs. With a general overview of the framework by Hiary and Ng (2005), the paper focuses on automated processes which determine the configuration of processing parameters in order to allow optimal content processing without time-consuming manual intervention. With a machine readable graphical representation of the watermark, cataloguing and indexing of these heritage resources can be enhanced with the ease of digital content retrieval functionalities for scholarly usages and many other advantages of digital technologies including distribution and preservation

The applicability of universal pragmatics in information retrieval interaction: a pilot study
This article discusses the possibility and usefulness of applying Habermas' universal pragmatics to analyze information retrieval interaction. The first part of the article is theoretical argumentation. It examines the current common schemes of studies of human computer interaction (HCI), inspects their appropriateness and limitations, argues for a pragmatic perspective, and elaborates some of Habermas' idea of universal pragmatics. The second part is a case study. It reports an investigation of the initiation and development of verification of validity claims in HCI from the universal pragmatics perspective. It describes some patterns in which a user deals with what may be considered as invalid claims of an IR system outputs. A typical sequence consists of the following pattern: (1) user invokes a simple request; (2) system replies with a questionable answer; leading to (3) user tries to verify the validity claims of truth, truthfulness, and/ or rightness of the system output; and (4) when the available interaction channels cannot support the validation, the interaction becomes a non-communicative process which discourages further interaction.

On optimal orientation of cycle vertex multiplications
For a bridgeless connected graph G, let D(G) be the family of its strong orientations; and for any [email protected]?D(G), we denote by d(D) its diameter. The orientation number d->(G) of G is defined by d->(G)=min{d(D)|[email protected]?D(G)}. For a connected graph G of order n and for any sequence of n positive integers (s"i), let G(s"1,s"2,...,s"n) denote the graph with vertex set V^* and edge set E^* such that V^*[email protected]?"i"="1^nV"i, where V"i's are pairwise disjoint sets with |V"i|=s"i, i=1,2,...,n, and for any two distinct vertices x, y in V^*, [email protected]?E^* if and only if [email protected]?V"i and [email protected]?V"j for some i,[email protected]?{1,2,...,n} with i j such that v"iv"[email protected]?E(G). We call the graph G(s"1,s"2,...,s"n) a G vertex multiplication. In this paper, we determine the orientation numbers of various cycle vertex multiplications.

On best restricted range approximation in continuous complex-valued function spaces
To provide a Kolmogorov-type condition for characterizing a best approximation in a continuous complex-valued function space, it is usually assumed that the family of closed convex sets in the complex plane used to restrict the range satisfies a strong interior-point condition, and this excludes the interesting case when some @W"t is a line-segment or a singleton. The main aim of the present paper is to remove this restriction by virtue of a study of the notion of the strong CHIP for an infinite system of closed convex sets in a continuous complex-valued function space.

A Comparison of the Two Traditions of Metadata Development
The two traditional methods of Metadata Development as describe in the article are bibliographic control approach and the data management approach. These two approaches have evolved over time due to the rise of digital information stored in cyberspace and help facilitate metadata standards which include the identification, location, retrieval, manipulation and use of the information. So what is metadata? From my understanding of what metadata is, metadata is simply defined as 'data about data'. And to a certain extent and depending on the perspective which you define what metadata is, 'data about data' is a legitimate and accurate definition. Soyeon Park (1999), define metadata as " structured data about data " whereas NISO Press, 2004 describes metadata as " data about data or information about information. " But according to Gill, 2000, " information about information " is often " incorrectly generalized " by the reader or author as the meaning of metadata, therefore, 'data about data' would be more concise and accurate for this paper. This begs the question of exactly the purpose of metadata and metadata standards. In theory, " metadata provides an effective mechanism for identifying and locating data that is relevant to a particular user. " elements within the metadata standards may be divided into two categories: intrinsic (related to resource identification and discovery) and extrinsic (related administration and other nonbibliographic data). While some metadata formats vary in terms of intrinsic and extrinsic elements, some elements are more suitable for resource description and identification whereas others may help resource access and navigation. However, the issue still remains as to which metadata format to use and whether a universal or unified " grand scheme " that is rich in attribute should be employed, eliminating the need in choosing a specific metadata format. In the past years, we have seen a rise of conflicting standards as an increasingly large amount of information becomes available electronically. This has become a growing problem as retrieving information becomes more complex. In an article by Jessica Milstead and Susan Feldman (1999), the author uses the term " Mercury " as an example of the documents the user would retrieve through the use of

The iterative development of a tangible pin-board to symmetrically link physical and digital documents
There is an asymmetry in many tangible interfaces: while physical objects can be used to manipulate digital information, the reverse is often not possible—the digital world cannot push back. We introduce a new push-back tangible technology, a pin-board that physically ejects paper documents. This is realized by extending the Pin&Play technology to support ‘pouts’, addressable pin-like devices that can remove themselves from a board using muscle wire actuators. We describe how this technology has been developed through two iterations of prototyping, application and formative study. An initial study revealed how potential mismatches between the physical and digital characteristics of pouts caused difficulties with users predicting pop-out events and reasoning about the state of pouts. This led us to extend pouts to reveal more of their internal state, an approach verified through a second study. It also raises more general issues for the design of pushback tangible technologies and ubiquitous interfaces.
