Konferensbidrag (refereegranskat)abstract
- his paper briefly describes the components of the ARCOMEM architecture concerned with the extraction, enrichment, consolidation and dynamics analysis of entities, topics and events, deploying text mining, NLP, and semantic data integration technologies. In particular, we focus on four main areas relevant to support the ARCOMEM requirements and use cases: (a) entity and event extraction from text; (b) entity and event enrichment and consolidation; (c) topicdetection and dynamics; and (d) temporal aspects and dynamics detection in Web language and online social networks.

- Purpose - Research in the area of technology-enhanced learning (TEL) throughout the last decade has largely focused on sharing and reusing educational resources and data. This effort has led to a fragmented landscape of competing metadata schemas, or interface mechanisms. More recently, semantic technologies were taken into account to improve interoperability. The linked data approach has emerged as the de facto standard for sharing data on the web. To this end, it is obvious that the application of linked data principles offers a large potential to solve interoperability issues in the field of TEL. This paper aims to address this issue. Design/methodology/approach - In this paper, approaches are surveyed that are aimed towards a vision of linked education, i.e. education which exploits educational web data. It particularly considers the exploitation of the wealth of already existing TEL data on the web by allowing its exposure as linked data and by taking into account automated enrichment and interlinking techniques to provide rich and well-interlinked data for the educational domain. Findings - So far web-scale integration of educational resources is not facilitated, mainly due to the lack of take-up of shared principles, datasets and schemas. However, linked data principles increasingly are recognized by the TEL community. The paper provides a structured assessment and classification of existing challenges and approaches, serving as potential guideline for researchers and practitioners in the field. Originality/value - Being one of the first comprehensive surveys on the topic of linked data for education, the paper has the potential to become a widely recognized reference publication in the area.

Tidskriftsartikel (refereegranskat)abstract
- Organic pig farming aims at maintaining a high health and welfare state of the animals through appropriate housing, management and feeding. Better knowledge of health and welfare indicators should help to identify critical points and hence to improve health and welfare as well as performance of organic pigs. This paper describes the health and welfare of organic pigs from 101 farms across six EU countries, using selected animal-based parameters from the Welfare Quality® protocol. Parameters were collected in sows, suckling and weaned piglets in 3 to 20 farms per country. Their assessment was trained before farm visits and inter-observer agreement determined after farm visits. The most prevalent problems identified in sows were thinness (median farm prevalence 18.8 %, range 0–81.0), injuries on the anterior part of the body (15.5 %, 0–66.7), injuries on hind part of body (7.9 %, 0–50), obesity (4.9 %, 0–50.0) and vulva lesions (3.5 %, 0–42.9). In suckling piglets, the median prevalence in terms of groups affected per farm was 0 % for all parameters but ‘> 50 % dirty piglets in group’, for which it was 10 %. Farm prevalence ranged from 0 to 100 % for ‘≥ 1 lame piglet in group’, presence of diarrhoea, and ‘> 50 % dirty piglets in group’. In weaned piglets, the median prevalence in terms of groups affected per farm was 0 % with a range of 0 to 100 % for all parameters. Based on the collected data, body condition, skin and vulva lesions in sows, lameness, diarrhoea and respiratory problems in piglets could be used as management and welfare indicators, with good potential for enhancement through farm improvement schemes like herd health planning. However, some definitions could be improved, especially lameness, diarrhoea and respiratory problems in piglets.
