Topical Classification of Food Safety Publications with a Knowledge Base

The vast body of scientific publications presents an increasing challenge of finding those that are relevant to a given research question, and making informed decisions on their basis. This becomes extremely difficult without the use of automated tools. Here, one possible area for improvement is automatic classification of publication abstracts according to their topic. This work introduces a novel, knowledge base-oriented publication classifier. The proposed method focuses on achieving scalability and easy adaptability to other domains. Classification speed and accuracy are shown to be satisfactory, in the very demanding field of food safety. Further development and evaluation of the method is needed, as the proposed approach shows much potential

Ontology Reuse: the Real Test of Ontological Design

Reusing ontologies in practice is still very challenging, especially when multiple ontologies are (jointly) involved. Moreover, despite recent advances, the realization of systematic ontology quality assurance remains a difficult problem. In this work, the quality of thirty biomedical ontologies, and the Computer Science Ontology are investigated, from the perspective of a practical use case. Special scrutiny is given to cross-ontology references, which are vital for combining ontologies. Diverse methods to detect potential issues are proposed, including natural language processing and network analysis. Moreover, several suggestions for improving ontologies and their quality assurance processes are presented. It is argued that while the advancing automatic tools for ontology quality assurance are crucial for ontology improvement, they will not solve the problem entirely. It is ontology reuse that is the ultimate method for continuously verifying and improving ontology quality, as well as for guiding its future development. Specifically, multiple issues can be found and fixed primarily through practical and diverse ontology reuse scenarios.Comment: Accepted into SOMET 2022 conferenc

RiverBench: an Open RDF Streaming Benchmark Suite

RDF data streaming has been explored by the Semantic Web community from many angles, resulting in multiple task formulations and streaming methods. However, for many existing formulations of the problem, reliably benchmarking streaming solutions has been challenging due to the lack of well-described and appropriately diverse benchmark datasets. Existing datasets and evaluations, except a few notable cases, suffer from unclear streaming task scopes, underspecified benchmarks, and errors in the data. To address these issues, we firstly systematize the different RDF data streaming tasks in a clear taxonomy and outline practical requirements for benchmark datasets. We then propose RiverBench, an open and collaborative RDF streaming benchmark suite that applies these principles in practice. RiverBench leverages continuous, community-driven processes, established best practices (e.g., FAIR), and built-in quality guarantees. The suite distributes datasets in a common, accessible format, with clear documentation, licensing, and machine-readable metadata. The current release includes a diverse collection of non-synthetic datasets generated by the Semantic Web community, representing many applications of RDF data streaming, all major task formulations, and emerging RDF features (RDF-star). Finally, we present a list of research applications for the suite, demonstrating its versatility and value even beyond the realm of RDF streaming.Comment: RiverBench is available online here: https://w3id.org/riverbenc

Cloud-Native Workload Orchestration at the Edge: A Deployment Review and Future Directions

[EN] Cloud-native computing principles such as virtualization and orchestration are key to transferring to the promising paradigm of edge computing. Challenges of containerization, operative models and scarce availability of established tools make a thorough review indispensable. Therefore, the authors have described the practical methods and tools found in the literature as well as in current community-led development projects, and have thoroughly exposed the future directions of the field. Container virtualization and its orchestration through Kubernetes have dominated the cloud computing domain, while major efforts have been recently recorded focused on the adaptation of these technologies to the edge. Such initiatives have addressed either the reduction of container engines and the development of specific tailored operating systems or the development of smaller K8s distributions and edge-focused adaptations (such as KubeEdge). Finally, new workload virtualization approaches, such as WebAssembly modules together with the joint orchestration of these heterogeneous workloads, seem to be the topics to pay attention to in the short to medium term.This research was funded by the European Commission under the Horizon Europe project aerOS, grant number 101069732.Vañó, R.; Lacalle, I.; Sowinski, P.; S-Julián, R.; Palau Salvador, CE.

The Influence of Chestnut Flour on the Quality of Gluten-Free Bread

Gluten-free bread is the basis of an elimination diet in the case of many glucose-related diseases. The quality of this bread differs significantly from traditional products; therefore, it is necessary to conduct research aimed at improving the quality of this type of product. The aim of the study was to determine the effect of the addition of chestnut flour and the method of packaging on the quality of gluten-free bread. The addition of chestnut flour (partially replacing corn starch) was used in the amount of 5, 10, 15 and 20% of the total weight of the concentrate. The influence of the storage method on the quality of the tested bread was examined after 7, 14 and 21 days from baking. The refrigerated breads were packed using PA/PE barrier foil with air and vacuum (58%) and were stored in room temperature (22 ± 2 °C). Water content, texture and color were determined, and sensory evaluation and microbiological analysis were performed. As a result of the conducted research, we observed that the addition of chestnut flour to the recipe affects significantly (p p < 0.05) the volume of the resulting loaves. Microbiological research has indicated vacuum packaging as a better way to protect and store gluten-free bread. For practical use in future production, it is recommended to replace corn starch in gluten-free breads by no more than 10% by chestnut flour

As a result of the conducted research, we observed that the addition of chestnut flour to the recipe affects significantly (p &lt; 0.05) the texture of the finished product, reducing the hardness and increasing the elasticity and cohesiveness of the bread crumb. The use of chestnut flour in an amount of up to 10% increases significantly (p &lt; 0.05) the volume of the resulting loaves. Microbiological research has indicated vacuum packaging as a better way to protect and store gluten-free bread.

Effect of high-dose heparin on uptake upstream and downstream of the branch.

<p>Effect of pre-treatment with high-dose heparin for 1h on the difference in transport between regions of interest upstream and downstream of the branch in rabbits of different age, quantifying aspects of the patterns shown in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0120363#pone.0120363.g009" target="_blank">Fig. 9</a>. Data are presented as described in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0120363#pone.0120363.g002" target="_blank">Fig. 2</a>. The direction of the difference was reversed by 1h heparin treatment in ex-breeder animals (p = 0.0131).</p

Effect of duration of uptake on streaks.

<p>(a and b) Maps of mass transfer coefficients over a segment of aorta, displayed as in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0120363#pone.0120363.g006" target="_blank">Fig. 6</a>. The aortas were exposed to circulating tracer for (a) 10 or (b) 1 min <i>in vivo</i> and then flushed and fixed <i>via</i> a retrograde cannula inserted after death. (c) A portion of map (b) superimposed on a 3D representation of wall structure, and a 2D slice through the 3D image. Note that depth into the wall is shown on an expanded scale compared to the axial and circumferential dimensions (all in microns).</p

Uptake over wider areas.

<p>(a-d) Maps of mass transfer coefficients over a segment of aorta containing two pairs of intercostal branch ostia from a representative rabbit in each age group. Dimensions are shown in mm. Colour bars indicate mass transfer coefficients in cm/s. Mean aortic flow is from the top to the bottom of each map. Branch ostia are indicated by white circles. (Other holes are imaging artefacts). The histogram under each map shows the circumferential variation in mass transfer coefficients, quantified by averaging data in 5 elongated regions of interest located close to the left lateral margin and the right lateral margin of the map, between left branch ostia and between right branch ostia, and along the dorsal midline. (These regions avoided the areas immediately around the branches themselves, and the narrow longitudinal streaks of high uptake shown in subsequent figures.) The data (shown as mean±SEM) were obtained for all rabbits in each age group, not just the example maps.</p

The difference in tracer uptake between regions upstream and downstream of the branch.

<p>Differences are expressed as a percentage of the mean of both regions at the different ages. Positive values indicate higher uptake downstream whilst negative values indicate higher uptake upstream. The trend with age between the three mature groups was significant (p<0.01). Data are shown as mean±SEM.</p
