A key point in achieving accurate intact glycopeptide identification is the definition of the glycan composition file that is used to match experimental with theoretical masses by a glycoproteomics search engine. At present, these files are mainly built from searching the literature and/or querying data sources focused on posttranslational modifications. Most glycoproteomics search engines include a default composition file that is readily used when processing MS data. We introduce here a glycan composition visualizing and comparative tool associated with the GlyConnect database and called GlyConnect Compozitor. It offers a web interface through which the database can be queried to bring out contextual information relative to a set of glycan compositions. The tool takes advantage of compositions being related to one another through shared monosaccharide counts and outputs interactive graphs summarizing information searched in the database. These results provide a guide for selecting or deselecting compositions in a file in order to reflect the context of a study as closely as possible. They also confirm the consistency of a set of compositions based on the content of the GlyConnect database. As part of the tool collection of the Glycomics@ExPASy initiative, Compozitor is hosted at https://glyconnect.expasy.org/compozitor/ where it can be run as a web application. It is also directly accessible from the GlyConnect database.

In the not too distant past, the amount of online data available to general users was relatively small. Most of the online data was maintained in organizations' database management systems and accessible only through the interfaces provided by those systems. The popularity of the Internet, in particular, has meant that there is now an abundance of online data available to users in the form of Web pages and files. This data, however, is maintained in passive data sources, that is sources that do not provide facilities to search or query their data. The data must be queried and examined using applications such as browsers and search engines. In this paper, we explore an approach to querying passive data sources based on the extraction, and subsequent exploitation, of metadata from the data sources. We describe two situations in which this approach has been used, evaluate the approach and draw some general conclusions.

ABSTRACT Objective: to map the production of knowledge about the recommendations that can be applied in managing patients diagnosed or suspected with COVID-19 in cardiorespiratory arrest. Method: a scoping review, according to the Joanna Briggs Institute (2020) guidelines. Search was performed in ten data sources, and two electronic search engines were used; from 2001 to 2020. Results: of the 547 studies found, 14 met the inclusion and exclusion criteria. Most studies were published in 2020 (35.7%), and most studies were conducted in Canada (21.4%). It is observed the use of a systematized care to identify the possible means of care that should be provided to patients who suffer a cardiorespiratory arrest in hospitals, such as the monitoring of suspected cases by assessing the victim’s breathing and pulse and identifying arrhythmias and shockable rhythms quickly. Personal protective equipment must be used to protect against droplets and aerosols and respiratory etiquette. Conclusion: managing patients in cardiorespiratory arrest suspected or diagnosis with COVID-19 requiring cardiopulmonary resuscitation should be performed in isolation areas and with the use of adequate protective equipment. There are gaps in scientific productions so that they address more clearly and instructively management when performing cardiopulmonary resuscitation in patients suspected or diagnosed with COVID-19.

The process of refining the research question in a medical study depends greatly on the current background of the investigated subject. The information found in prior works can directly impact several stages of the study, namely the cohort definition stage. Besides previous published methods, researchers could also leverage on other materials, such as the output of cohort selection tools, to enrich and to accelerate their own work. However, this kind of information is not always captured by search engines. In this paper, we present a methodology, based on a combination of content-based retrieval and text annotation techniques, to identify relevant scientific publications related to a research question and to the selected data sources.

The challenge of finding, retrieving and making sense of biodiversity data is being tackled by many different approaches. Projects like the Global Biodiversity Information Facility (GBIF) or Encyclopedia of Life (EoL) adopt an integrative approach where they republish, in a uniform manner, records aggregated from multiple data sources. With this centralized, siloed approach, such projects stand as powerful one-stop shops, but tend to reduce the visibility of other data sources that are not (yet) aggregated. At the other end of the spectrum, the Web of Data promotes the building of a global, distributed knowledge graph consisting of datasets published by independent institutions according to the Linked Open Data principles (Heath and Bizer 2011), such as Wikidata or DBpedia. Beyond these "sophisticated" infrastructures, websites remain the most common way of publishing and sharing scientific data at low cost. Thanks to web search engines, everyone can discover webpages. Yet, the summaries provided in results lists are often insufficiently informative to decide whether a web page is relevant with respect to some research interests, such that integrating data published by a wealth of websites is hardly possible. A strategy around this issue lies in annotating websites with structured, semantic metadata such as the Schema.org vocabulary (Guha et al. 2015). Webpages typically embed Schema.org annotations in the form of markup data (written in the RDFa or JSON-LD formats), which search engines harvest and exploit to improve ranking and provide more informative summarization. Bioschemas is a community effort working to extend Schema.org to support markup for Life Sciences websites (Michel and The Bioschemas Community 2018, Garcia et al. 2017). Bioschemas primarily re-uses existing terms from Schema.org, occasionally re-uses terms from third-party vocabularies, and when necessary proposes new terms to be endorsed by Schema.org. As of today, Bioschemas's biodiversity group has proposed the Taxon type*1 to support the annotation of any webpage denoting taxa, TaxonName to support more specifically the annotation of taxonomic names registries, and guidelines describing how to leverage existing vocabularies such as Darwin Core terms. To proceed further, the biodiversity community must now demonstrate its interest in having these terms endorsed by Schema.org: (1) through a critical mass of live markup deployments, and (2) by the development of applications capable of exploiting this markup data. Therefore, as a first step, the French National Museum of Natural History has marked up its natural heritage inventory website: over 180,000 webpages describing the species inventoried in French territories have been annotated with the Taxon and TaxonName types in the form of JSON-LD scripts (see example scripts). As an example, one can check the source of the Delphinus delphis page. In this presentation, by demonstrating that marking up existing webpages can be very inexpensive, we wish to encourage the biodiversity community to adopt this practice, engage in the discussion about biodiversity-related markup, and possibly propose new terms related e.g. to traits or collections. We believe that generalizing the use of such markup by the many websites reporting checklists, museum collections, occurrences, life traits etc. shall be a major step towards the generalized adoption of FAIR*2 principles (Wilkinson 2016), shall dramatically improve information discovery using search engines, and shall be a key accelerator for the development of novel, web-scale, biodiversity data integration scenarios.

Code search engines usually use readability feature to rank code snippets. There are several metrics to calculate this feature, but developers may have different perceptions about readability. Correlation between readability and understandability features has already been proposed, i.e., developers need to read and comprehend the code snippet syntax, but also understand the semantics. This work investigate scores for understandability and readability features, under the perspective of the possible subjective perception of code snippet comprehension. We find that code snippets with higher readability score has better comprehension than lower ones. The understandability score presents better comprehension in specific situations, e.g. nested loops or if-else chains. The developers also mentioned writability aspects as the principal characteristic to evaluate code snippets comprehension. These results provide insights for future works in code comprehension score optimization.

In the digital memories literature, the practice of searching for information – one of the most frequent online activities worldwide – has received comparatively little attention. To fill the gap, this exploratory study asks how search engines affect the representations of the past that they produce in query results. Designed as a single revelatory case study, with a focus on Russia, this article delineates a typology of four types of memory events based on four types of websites dominating search results. For each type of event, we discuss recurring locations and mechanisms of power struggles over competing memory narratives. We conclude that within Russia’s authoritarian context, the mnemonic practice of Internet searching tends to reproduce and reinforce the dominant narratives supported by the ruling elites. Search engine companies are thus only one of several powerful institutions that constitute the social framework within which querying the Internet is pursued as a mnemonic practice. Others include mass media, non-governmental organisations (NGOs), and online encyclopaedias.
