The work is devoted to one of the components of a scientific work – acknowledgements. The description of this component, various means of its expression, possible addressees are given. The purpose of this article is to describe how to include this data in the search criteria of automatic search engines, as well as the analytical capabilities associated with this component. The analysis of publications in the professional literature is conducted, where expressions of аcknowledgements are given by the authors of scientific works. The technical methods of including information about gratitude into the bibliographic record are described on the example of the ABIS «Ruslan» and «Irbis». It was revealed that acknowledgments are considered mainly to assess the sources of research funding. Critical remarks are given regarding the value and objectivity of using this element in this capacity. It has been established that the expression of gratitude given in a scientific work, primarily in a scientific article, is of great research importance. A promising way to use this component to identify informal connections between scientists is proposed.

RASE: A Real-Time Automatic Search Engine for Anomalous Seismic Electric Signals in Geoelectric Data

The geoelectric data contain important anomalous information for short-term earthquake prediction. Timely and accurate identification of seismic electric anomalies is important for disaster prevention. However, identifying anomalies is challenging due to the huge volumes of data and noise disturbance. In this study, we develop a real-time automatic search engine (RASE) that incorporates an unsupervised convolutional denoising network (UCN) module and a supervised LSTM network (SLN) prediction module to automatically search for important anomalous signals in real-time. Experiments demonstrate that the RASE provides excellent detection accuracy and efficiency for synthetic and field data, which takes only dozens of seconds for a common PC to provide accurate detection results for data collected over a 24-hour period. The RASE has excellent flexibility and developability, as its internal modules can be adapted by more suitable technologies for better performance in various application scenarios. Comparison of multiple module combinations shows that the RASE configured with UCN and SLN has the highest detection accuracy. Our proposed search engine can reduce the human labor required for complex and repetitive detection work and fully realize the potential of geoelectric field observation in earthquake monitoring and disaster prevention.

A Systematic Evaluation of Mobile Health Applications for the Prevention of Suicidal Behavior or Non-suicidal Self-injury.

People with suicidal ideation and non-suicidal self-injury (NSSI) behavior face numerous barriers to help-seeking, which worsened during the COVID-19 pandemic. Mobile health applications (MHA) are discussed as one solution to improve healthcare. However, the commercial app markets are growing unregulated and rapidly, leading to an inscrutable market. This study evaluates the quality, features, functions, and prevention strategies of MHA for people with suicidal ideation and NSSI. An automatic search engine identified MHA for suicidal behavior and NSSI in the European commercial app stores. MHA quality and general characteristics were assessed using the Mobile Application Rating Scale (MARS). MHA of high quality (top 25%) were examined in detail and checked for consistency with established suicide prevention strategies. Of 10,274 identified apps, 179 MHA met the predefined inclusion criteria. Average MHA quality was moderate (M = 3.56, SD = 0.40). Most MHA provided emergency contact, but lacked security features. High-quality MHA were broadly consistent with the best-practice guidelines. The search revealed apps containing potentially harmful and triggering content, and no randomized controlled trial of any included MHA was found. Despite a large heterogeneity in the quality of MHA, high-quality MHA for suicidal behavior and NSSI are available in European commercial app stores. However, a lack of a scientific evidence base poses potential threats to users.

Assessing Awareness on Open Education by Means of Online Research Tools

The data and visualisations discussed in this paper illustrate the impact of various key phrases, core to the education movement, on the World Wide Web at large as well as on some particular realms of online activity. Various digital methods and webometrics techniques were used with the aim of collecting and analysing relevant data. In particular, two so-called automatic search engine query submitters were used, namely the Webometrics Analyst and the Google Scraper. The analysis focuses on the impact of the phrases recursos educativos abiertos and contenido abierto (equivalent in Spanish to the terms open educational resources and open content respectively) on the HE sector of Spanish-speaking countries in Latin America.Work presented at the UNESCO Open Educational Resources (OER) World Congress. Paris, 20th-22nd June 2012.

Automatic Search Engine Performance Evaluation Based on User Behavior Analysis

With click-through data analysis,an automatic search engine performance evaluation method is proposed.This method generates navigational type query topics and answers automatically based on search users' querying and clicking behavior.Experimental results based on a commercial Chinese search engine's user logs show that the automatic method gets a similar evaluation result with the traditional assessor-based ones.This method can also provide timely evaluation results with little human efforts.

Introduction to Webometrics: Quantitative Web Research for the Social Sciences

Webometrics is concerned with measuring aspects of the web: web sites, web pages, parts of web pages, words in web pages, hyperlinks, web search engine results. The importance of the web itself as a communication medium and for hosting an increasingly wide array of documents, from journal articles to holiday brochures, needs no introduction. Given this huge and easily accessible source of information, there are limitless possibilities for measuring or counting on a huge scale (e.g., the number of web sites, the number of web pages, the number of blogs) or on a smaller scale (e.g., the number of web sites in Ireland, the number of web pages in the CNN web site, the number of blogs mentioning Barack Obama before the 2008 presidential campaign). This book argues that it can be useful for social scientists to measure aspects of the web and explains how this can be achieved on both a small and large scale. The book is intended for social scientists with research topics that are wholly or partly online (e.g., social networks, news, political communication) and social scientists with offline research topics with an online reflection, even if this is not a core component (e.g., diaspora communities, consumer culture, linguistic change). The book is also intended for library and information science students in the belief that the knowledge and techniques described will be useful for them to guide and aid other social scientists in their research. In addition, the techniques and issues are all directly relevant to library and information science research problems.

Formation of ε-Formyllysine on Silver-stained Proteins: Implications for Assignment of Isobaric Dimethylation Sites by Tandem Mass Spectrometry

Considerable effort is focused presently on the detection and comprehensive assignment of post-translational modifications of proteins. Obviously attention must be paid to the possibility of chemical modifications that may occur to protein samples during sample handling and manipulation prior to analysis by tandem mass spectrometry. This is of particular concern when a modification is isobaric with the mass differential in common with a known post-translational analog. Here we provide evidence that silver staining protocols that use formaldehyde can result in epsilon-formylation of lysine residues. This modification is in fact isobaric with the important product of methyltransferases, epsilon,epsilon-dimethyllysine. Without exercising proper caution the analysis of silver-stained protein samples by mass spectrometry looking for dimethylation of lysine will yield a significant number of misassigned sites of modification. High accuracy measurements of the mass of the precursor ions and their fragments are required to eliminate this uncertainty. The occurrence of dimethylation of the epsilon-amino function of lysine residues has been reported often in histones. For histone samples excised from silver-stained gels, we found that most sites initially assigned to be dimethylated by automatic search engines under standard search parameters (100 ppm error tolerance) are actually in fact formylated. Caution must be exercised when data obtained from instruments unable to perform high accuracy mass measurements (better than 5 ppm) are to be interpreted.

Preprocessing of tandem mass spectrometric data to support automatic protein identification.

Liquid chromatography tandem mass spectrometry is a major tool for identifying proteins. The fragment spectra of peptides can be interpreted automatically in conjunction with a sequence database search. With the development of powerful automatic search engines, research now focuses on optimizing the result returned from database searches. We present a series of preprocessing steps for fragment spectra to increase the accuracy and specificity of automatic database searches. After processing, the correct amino acid sequences from the database can be related better to the fragment spectra. This increases the sensitivity and reliability of protein identifications, especially with very large genomic databanks, and can be important for the systematic characterization of post-translational modifications.

Value-sensitive automatic code specialization for embedded software

The objective of this work is to create a framework for the optimization of embedded software. We present algorithms and a tool flow to reduce the computational effort of programs, using value profiling and partial evaluation. Such a reduction translates into both energy savings and average-case performance improvement, while preserving a tolerable increase of worst case performance and code size. Our tool reduces the computational effort by specializing frequently executed procedures for the most common values of their parameters. The most effective specializations are automatically searched and identified, and the code is transformed through partial evaluation. Experimental results show that their technique improves both energy consumption and performance of the source code up to more than a factor of two, in average about 35% over the original program. Also, their automatic search engine greatly reduces code optimization time with respect to exhaustive search.

The FALMER Project: an electronic critical edition

What will be the critical editions in the electronic era? Hubert de Phalese, a research centre in La Sorbonne-Nouvelle University (Paris III), in accordance with its pragmatic approach to literary computing problems, decided to launch this debate by putting on line a critical edition of the complete works of Lautreamont/Isidore Ducasse (http://www.cavi.univ-paris3.fr/phalese). This edition is an integral hypertext (in which nearly every word of the text is linked with a comment), which gathers all that one usually finds in critical editions, but on a scale that does not have equivalents on paper: variants, philological, literary and encyclopedic comments, biography, bibliography, iconography, index, etc. This prototype poses, concretely, a certain number of problems, on several levels: Technical: Which interface is to be used? The purely automatic search engines (including the uses of Java and other script languages) appeared unsuited and a new device of computer-assisted indexing was developed. It makes it possible to provide for the user a lemmatized index and, especially, lexical cards, which can be enriched at will. The current solution of setting on-line presents some inconveniences but it has the advantage of proposing to the greatest number of users the consultation of the edition and of inviting them to take part in it. Contents: The new support is, virtually, infinite. What is a critical edition to contain now that we are no longer concerned with its volume? All the versions of the text, for example, can now be proposed with the reading. But are we to publish the intertexts, contemporary works, criticism, etc.? How can the interconnection, in a network, of several resources enrich a critical edition? Under which scientific and legal conditions? Validation: Can this type of edition be regarded as more reliable than the paper editions? According to which protocols will such editions be judged? One of the risks is the appearance of a great quantity of work

A statistical study of evening sector arcs and electrojets

We present results of a statistical study of evening sector auroral arcs associated with electrojets. The study (including ∼ 1000 all-sky camera (ASC) frames) is based on data of the MIRACLE instrument network. An automatic search engine is used to define the arc periods from ASC data and the recordings of the IMAGE magnetometer network are used to estimate the strength and location of the equivalent electrojet currents. The maximum current densities and intensities of the equivalent electrojets vary in the ranges 200–600 A/km and 200–400 kA, respectively. In 85 % of cases with single arcs the current system is of a convection reversal type (an eastward electrojet equatorward of a westward electrojet). Usually the arc is within 1° distance from the latitude of maximum eastward current density which is ≤4° south from the transition region between the westward and eastward electrojets. Most of such events were observed in the dusk sector, not in the premidnight-sector, which is generally considered as the typical Harang discontinuity (HD) region of convection reversal type currents. Furthermore, the poleward boundary of the westward current is very often poleward of the northernmost IMAGE station (CGM lat. ∼76), which may mean that the westward currents are not real horizontal currents but equivalent currents due to field aligned R1 currents. This implies that a stable arc often resides a few degrees equatorward to the evening shell potential minimum. We discuss the implications of these findings from the viewpoint of previous HD-studies.

World‐Wide Web searching tools: an evaluation

Many tools exist to provide subject access to information stored on the Web. These include both automatic search engines such as ‘crawler’ programs and manually‐created subject indexes. In this article, four search engines and two subject collections with a search facility are compared in terms of their content, interface, search features, output and performance. For comprehensive searches of Web material, no single tool was found to be satisfactorily effective, and doubts remain as to whether such tools can yet be incorporated in the mainstream of online searching.
