Deliverable 4.5: Context-aware Content Interpretation
- 2016
-
Rapport (refereegranskat)abstract
- The current deliverable summarises the work conducted within task T4.5 of WP4, presenting our proposed approaches for contextualised content interpretation, aimed at gaining insightful contextualised views on content semantics. This is achieved through the adoption of appropriate context-aware semantic models developed within the project, and via enriching the semantic descriptions with background knowledge, deriving thus higher level contextualised content interpretations that are closer to human perception and appraisal needs. More specifically, the main contributions of the deliverable are the following: A theoretical framework using physics as a metaphor to develop different models of evolving semantic content. A set of proof-of-concept models for semantic drifts due to field dynamics, introducing two methods to identify quantum-like (QL) patterns in evolving information searching behaviour, and a QL model akin to particle-wave duality for semantic content classification. Integration of two specific tools, Somoclu for drift detection and Ncpol2spda for entanglement detection. An “energetic” hypothesis accounting for contextualized evolving semantic structures over time. A proposed semantic interpretation framework, integrating (a) an ontological inference scheme based on Description Logics (DL), (b) a rule-based reasoning layer built on SPARQL Inference Notation (SPIN), (c) an uncertainty management framework based on non-monotonic logics. A novel scheme for contextualized reasoning on semantic drift, based on LRM dependencies and OWL’s punning mechanism. An implementation of SPIN rules for policy and ecosystem change management, with the adoption of LRM preconditions and impacts. Specific use case scenarios demonstrate the context under development and the efficiency of the approach. Respective open-source implementations and experimental results that validate all the above.All these contributions are tightly interlinked with the other PERICLES work packages: WP2 supplies the use cases and sample datasets for validating our proposed approaches, WP3 provides the models (LRM and Digital Ecosystem models) that form the basis for our semantic representations of content and context, WP5 provides the practical application of the technologies developed to preservation processes, while the tools and algorithms presented in this deliverable can be deployed in combination with test scenarios, which will be part of the WP6 test beds.

PERICLES Deliverable 4.3: Content Semantics and Use Context Analysis Techniques
- 2016
-
Rapport (refereegranskat)abstract
- The current deliverable summarises the work conducted within task T4.3 of WP4, focusing on the extraction and the subsequent analysis of semantic information from digital content, which is imperative for its preservability. More specifically, the deliverable defines content semantic information from a visual and textual perspective, explains how this information can be exploited in long-term digital preservation and proposes novel approaches for extracting this information in a scalable manner. Additionally, the deliverable discusses novel techniques for retrieving and analysing the context of use of digital objects. Although this topic has not been extensively studied by existing literature, we believe use context is vital in augmenting the semantic information and maintaining the usability and preservability of the digital objects, as well as their ability to be accurately interpreted as initially intended.

- Management of change is essential to ensure the long-term reusabilityof digital assets. Change can be brought about in many ways, includingthrough technological, user community and policy factors. Motivated by casestudies in space science and time-based media, we consider the impact ofchange on complex digital objects comprising multiple interdependent entities,such as files, software and documentation. Our approach is based on modellingof digital ecosystems, in which abstract representations are used to assess risksto sustainability and support tasks such as appraisal. The paper is based onwork of the EU FP7 PERICLES project on digital preservation, and presentssome general concepts as well as a description of selected research areas underinvestigation by the project.

Annotating public fungal ITS sequences from the built environment according to the MIxS-Built Environment standard – a report from a May 23-24, 2016 workshop (Gothenburg, Sweden)
- 2016

Tidskriftsartikel (refereegranskat)abstract
- Recent molecular studies have identified substantial fungal diversity in indoor environments. Fungi and fungal particles have been linked to a range of potentially unwanted effects in the built environment, including asthma, decay of building materials, and food spoilage. The study of the built mycobiome is hampered by a number of constraints, one of which is the poor state of the metadata annotation of fungal DNA sequences from the built environment in public databases. In order to enable precise interrogation of such data – for example, “retrieve all fungal sequences recovered from bathrooms” – a workshop was organized at the University of Gothenburg (May 23-24, 2016) to annotate public fungal barcode (ITS) sequences according to the MIxS-Built Environment annotation standard (http://gensc.org/mixs/). The 36 participants assembled a total of 45,488 data points from the published literature, including the addition of 8,430 instances of countries of collection from a total of 83 countries, 5,801 instances of building types, and 3,876 instances of surface-air contaminants. The results were implemented in the UNITE database for molecular identification of fungi (http://unite.ut.ee) and were shared with other online resources. Data obtained from human/animal pathogenic fungi will furthermore be verified on culture based metadata for subsequent inclusion in the ISHAM-ITS database (http://its.mycologylab.org).

- Adverse work-related physical exposures such as repetitive movements and awkward postures have negative health effects and lead to large financial costs. To address these problems, a multi-disciplinary consortium was formed with the aim of developing an ambulatory system for recording and analyzing risks for musculoskeletal disorders utilizing textile integrated sensors as part of the regular workwear. This paper presents the consortium, the Smart Workwear System, and a case study illustrating its potential to decrease adverse biomechanical exposure by promoting improved work technique.

PERICLES Deliverable 4.4: Modelling Contextualised Semantics
- 2016
-
Rapport (refereegranskat)abstract
- The current deliverable summarises the work conducted within task T4.4 of WP4, presenting our proposed models for semantically representing digital content and its respective context – the latter refers to any information coming from the environment of the digital object (DO) that offers a better insight into the object’s status, its interrelationships with other content items and information about the object’s context of use. Within PERICLES, we refer to the content semantics enriched with the contextual perspective as “contextualised semantics”. The deliverable presents two complementary modelling approaches, based respectively on (a) ontologies and logics, and, (b) multivariate statistics.

Tidskriftsartikel (refereegranskat)abstract
- The supply chain strategy research has generated many frameworks for matching the supply chain with the nature of demand, market, consumers, or products. Recently many companies have implemented innovative new product development processes in order to increase revenue. However, research on the importance of the retailers for an original equipment manufacturer (OEM) adopting a leagile supply chain strategy for innovative products, is scarce. Using the case study method, this research investigates the need of collaboration between an OEM and its retailers. This research aims to richen the knowledge about demand supply chain management (DSCM), and the coordination of demand and supply processes between companies in the demand-supply chain. This research shows that there are several measures that may be used to monitor performance, and that collaboration is important for the case company.

Tidskriftsartikel (refereegranskat)abstract
- Effective implementation of the new product development (NPD) process not only enables management to coordinate the efficient flow of new products, but will also assist to support ramp-up of various supply chain activities and other related activities supporting the commercialisation of the product. Thus, companies need to address all these issues in parallel to be successful and this requires some kind of integrative product development approach. The purpose of this research is to increase the understanding of how NPD is connected to supply chain management (SCM) by investigating how the NPD process is structured and executed in two international manufacturing companies seeking to realise an innovative, predictable and efficient product development. Several essential linkages between NPD and SCM have been derived from case study findings concerning important issues for successful product development.

- Purpose – The purpose of this paper is to form an understanding of how new product development (NPD) relates to supply chain management (SCM), why the two fields should be coordinated, and how this may be done.Design/methodology/approach – This research uses a literature review and case study research. The case study considers a Swedish company that operates on a global basis in the furniture industry. Empirical data have been collected mainly from in-depth interviews with key persons representing senior and middle management in the case company.Findings – This paper stresses the need to produce innovative, value-adding products, as well as the necessity to quickly deliver them to the market. Companies that face mature business environments may encounter problems due to a high emphasis on either the value-creation processes, or on the value delivery processes. Therefore, NPD activities need to be coordinated with SCM activities on a strategic level, lest competitiveness will be lost.Research limitations/implications – The research is limited to one case company; replication studies would enhance understanding of the studied phenomenon. There is a wide need for research exploring how various parts of demand and supply chains should be managed in order to fully utilize the advantages of the consumer-oriented enterprise.Practical implications – This paper provides insights for researchers and practitioners on how to coordinate and balance NPD (demand side) with SCM (supply side) activities. It highlights that companies should organize themselves around understanding how consumer value is created and how these processes may be coordinated to provide that value. The two processes must be given equal attention and importance to avoid sub-optimization.Originality/value – The need for coordinating NPD and SCM activities has been emphasized in the literature but still remains relatively unexplored. This paper contributes by investigating this issue further.

- In recent years, Electrical Bioimpedance (EBI) methods have gained importance. These methods are often based on obtaining impedance spectrum in the range of β-dispersion, i.e. from a few kHz up to some MHz. To measure EBI a constant current is often injected and the voltage across the tissue under study (TUS) is recorded. Due to the performance of the current source influences the performance of the entire system, in terms of frequency range, several designs have been implemented and studied. In this paper the basic structure of a Voltage-Controlled Current Source (VCCS) based on a single Op-Amp in inverter configuration with a floating load, known as load-in-the-loop current source, is revisited and studied deeply. We focus on the dependence of the output impedance with the circuit parameters, i.e. the feedback resistor and the inverter-input resistor, and the Op-Amp main parameters, i.e. open loop gain, CMRR and input impedance. After obtaining the experimental results and comparing to the theoretical and simulated ones, they confirm the design under study can be a good solution for multi-frequency wideband EBI applications because of higher values of the output impedance than 100kΩ at 1MHz are obtained. Furthermore, an enhancement of the basic design, using a current conveyor as a first stage, is proposed, studied and implemented.
