Applying language technology to ontology-based querying : the OntoQuery project

This paper addresses the issue of how language technology resources and components can be applied in ontology-based querying. In particular, it presents the approach to text and query analysis adopted in the Danish research project OntoQuery, where shallow syntactic analysis and ontology-based parsing are combined in order to identify nominal phrases (NPs) and assign them a semantic description. Semantic descriptions are used by the search engine to match queries against texts in a database, and a ranking of the texts retrieved is produced based on a domain ontology. This is intended to be a general methodology applicable to texts from different domains, including those relevant to cultural heritage, although OntoQuery has chosen nutrition as its first target domain. The paper focuses on the language technology aspects of the methodology, the ontology-based lexicon inherited from the SIMPLE project, and the development of the domain-specific ontology. The methodology is partly implemented in a prototype.peer-reviewe

Humanities eInfrastructure initiatives in Denmark

ABSTRACT This paper presents an overview of the policies and decisions which have resulted in the current research infrastructure landscape in Denmark within the humanities, and it describes individual initiatives and how they fit into the landscape. The landscape was fragmented, and it still is to a degree, but one key factor has played a determining role in shaping it into what it is today: the European strategic processes and policies following from the development of the European Research Area, and the ESFRI (European Strategic Forum for Research Infrastructure) process, which has been adopted by Danish policy and decision makers. The strategies and priorities based on the European ESFRI process has resulted in funding of Danish research infrastructure (RI) initiatives within the humanities in the last 5-6 years, such that we can now define a landscape with national, Nordic and European collaboration and networking, extended into the social sciences community as well. The list of initiatives is comprehensive: CLARIN, META-NORD, META-NET, DARIAH, DASISH, CLARA, ASTIN, DIGHUMLAB, DIGDAG, LARM

Will emergency and surgical patients participate in and complete alcohol interventions? A systematic review

<p>Abstract</p> <p>Background</p> <p>In the everyday surgical life, staff may experience that patients with Alcohol Use Disorders (AUDs) seem reluctant to participate in alcohol intervention programs. The objective was therefore to assess acceptance of screening and intervention as well as adherence to the intervention program among emergency department (ED) and surgical patients with AUDs.</p> <p>Methods</p> <p>A systematic literature search was followed by extraction of acceptance and adherence rates in ED and surgical patients. Numbers needed to screen (NNS) were calculated. Subgroup analyses were carried out based on different study characteristics.</p> <p>Results</p> <p>The literature search revealed 33 relevant studies. Of these, 31 were randomized trials, 28 were conducted in EDs and 31 evaluated the effect of brief alcohol intervention. Follow-up was mainly conducted after six and/or twelve months.</p> <p>Four in five ED patients accepted alcohol screening and two in three accepted participation in intervention. In surgical patients, two in three accepted screening and the intervention acceptance rate was almost 100%. The adherence rate was above 60% for up to twelve months in both ED and surgical patients. The NNS to identify one eligible AUD patient and to get one eligible patient to accept participation in alcohol intervention varied from a few up to 70 patients.</p> <p>The rates did not differ between randomized and non-randomized trials, brief and intensive interventions or validated and self-reported alcohol consumption. Adherence rates were not affected by patients' group allocation and type of follow-up.</p> <p>Conclusions</p> <p>Most emergency and surgical patients with AUD accept participation in alcohol screening and interventions and complete the intervention program.</p

Whole grain-rich diet reduces body weight and systemic low-grade inflammation without inducing major changes of the gut microbiome: a randomised cross-over trial

Objective To investigate whether a whole grain diet alters the gut microbiome and insulin sensitivity, as well as biomarkers of metabolic health and gut functionality. Design 60 Danish adults at risk of developing metabolic syndrome were included in a randomised cross-over trial with two 8-week dietary intervention periods comprising whole grain diet and refined grain diet, separated by a washout period of ≥6 weeks. The response to the interventions on the gut microbiome composition and insulin sensitivity as well on measures of glucose and lipid metabolism, gut functionality, inflammatory markers, anthropometry and urine metabolomics were assessed. Results 50 participants completed both periods with a whole grain intake of 179±50 g/day and 13±10 g/day in the whole grain and refined grain period, respectively. Compliance was confirmed by a difference in plasma alkylresorcinols (p&lt;0.0001). Compared with refined grain, whole grain did not significantly alter glucose homeostasis and did not induce major changes in the faecal microbiome. Also, breath hydrogen levels, plasma short-chain fatty acids, intestinal integrity and intestinal transit time were not affected. The whole grain diet did, however, compared with the refined grain diet, decrease body weight (p&lt;0.0001), serum inflammatory markers, interleukin (IL)-6 (p=0.009) and C-reactive protein (p=0.003). The reduction in body weight was consistent with a reduction in energy intake, and IL-6 reduction was associated with the amount of whole grain consumed, in particular with intake of rye. Conclusion Compared with refined grain diet, whole grain diet did not alter insulin sensitivity and gut microbiome but reduced body weight and systemic low-grade inflammation

A low-gluten diet induces changes in the intestinal microbiome of healthy Danish adults

\ua9 2018, The Author(s). Adherence to a low-gluten diet has become increasingly common in parts of the general population. However, the effects of reducing gluten-rich food items including wheat, barley and rye cereals in healthy adults are unclear. Here, we undertook a randomised, controlled, cross-over trial involving 60 middle-aged Danish adults without known disorders with two 8-week interventions comparing a low-gluten diet (2 g gluten per day) and a high-gluten diet (18 g gluten per day), separated by a washout period of at least six weeks with habitual diet (12 g gluten per day). We find that, in comparison with a high-gluten diet, a low-gluten diet induces moderate changes in the intestinal microbiome, reduces fasting and postprandial hydrogen exhalation, and leads to improvements in self-reported bloating. These observations suggest that most of the effects of a low-gluten diet in non-coeliac adults may be driven by qualitative changes in dietary fibres
