From Web Catalogs to Google: A Retrospective Study of Web Search Engines Sustainable Development

This study presents a review of search engines and search engine optimization and shows how the search engine landscape relates to sustainable development. We have used a narrative review research method and described three main topics: the past and present of web catalogs and search engines; current knowledge about the dominant types of search results presented in Google search; and methods of search engine optimization. Technical elements of important website areas related to technical website auditing are discussed. We summarize our research with several key findings on how web search engines are involved in sustainable development and offer a glimpse into the future use of web searching with the help of artificial intelligence chats and prompt engineering.

Hemispheric distribution of coronal mass ejections from 1996 to 2020

ABSTRACT Solar magnetic structures are known to be asymmetrically distributed between the two hemispheres. To date, the hemispheric variations of the coronal mass ejections (CMEs) at different latitudes, in different cycles, and for different types (regular and specific events) are still unclear. From the list of white-light CMEs in the Coordinated Data Analysis Web catalogue, we investigate the hemispheric asymmetry of high-latitude and low-latitude CMEs in the time interval from 1996 January to 2020 December. The main results are shown for the following: (1) in each hemisphere, regular CMEs are significantly correlated with solar activity, particularly for low latitudes. However, specific CMEs are not correlated with solar activity; (2) the main reason for the hemispheric asymmetry of the CMEs is attributable to specific CMEs, not regular CMEs. The hemispheric asymmetry of high-latitude CMEs appears to have little connection to that of low-latitude CMEs; (3) for the total and specific CMEs, the relationship between the absolute asymmetry index at high and low latitudes has a positive correlation prior to the cycle maximum, but a negative correlation after the cycle maximum; and (4) the dominant hemisphere, the cumulative trend, and the amplitude of the total, specific, and regular CMEs in cycle 23 differ from those in cycle 24. Our analysis results could be useful for understanding the cyclical variation of the magnetic free energy during different solar cycles, and could also provide insight into more physical processes responsible for the solar–terrestrial relationship.

KOMPSAT Optical Image Data Provision and Quality Management

This paper describes KOrea Multi-Purpose SATellites (KOMPSAT-3 and KOMPSAT-3A) characteristics, operation, and image collection mode in order to enhance satellite image application. Also, image product of the satellites and quality management of the image product are described in this paper. The KOMPSAT-3 launched in 2012 and KOMPSAT-3A launched in 2015 collected many imageries around the world and provide them to users through web. Users can search for images through web catalog and order new imaging task. The KOMPSAT images provided under the KARI control is expected to be great help for earth observation and satellite image application enhancement.

GeoLOD: A Spatial Linked Data Catalog and Recommender

The increasing availability of linked data poses new challenges for the identification and retrieval of the most appropriate data sources that meet user needs. Recent dataset catalogs and recommenders provide advanced methods that facilitate linked data search, but none exploits the spatial characteristics of datasets. In this paper, we present GeoLOD, a web catalog of spatial datasets and classes and a recommender for spatial datasets and classes possibly relevant for link discovery processes. GeoLOD Catalog parses, maintains and generates metadata about datasets and classes provided by SPARQL endpoints that contain georeferenced point instances. It offers text and map-based search functionality and dataset descriptions in GeoVoID, a spatial dataset metadata template that extends VoID. GeoLOD Recommender pre-computes and maintains, for all identified spatial classes in the Web of Data (WoD), ranked lists of classes relevant for link discovery. In addition, the on-the-fly Recommender allows users to define an uncatalogued SPARQL endpoint, a GeoJSON or a Shapefile and get class recommendations in real time. Furthermore, generated recommendations can be automatically exported in SILK and LIMES configuration files in order to be used for a link discovery task. In the results, we provide statistics about the status and potential connectivity of spatial datasets in the WoD, we assess the applicability of the recommender, and we present the outcome of a system usability study. GeoLOD is the first catalog that targets both linked data experts and geographic information systems professionals, exploits geographical characteristics of datasets and provides an exhaustive list of WoD spatial datasets and classes along with class recommendations for link discovery.

Missense3D-DB web catalogue: an atom-based analysis and repository of 4M human protein-coding genetic variants

The interpretation of human genetic variation is one of the greatest challenges of modern genetics. New approaches are urgently needed to prioritize variants, especially those that are rare or lack a definitive clinical interpretation. We examined 10,136,597 human missense genetic variants from GnomAD, ClinVar and UniProt. We were able to perform large-scale atom-based mapping and phenotype interpretation of 3,960,015 of these variants onto 18,874 experimental and 84,818 in house predicted three-dimensional coordinates of the human proteome. We demonstrate that 14% of amino acid substitutions from the GnomAD database that could be structurally analysed are predicted to affect protein structure (n = 568,548, of which 566,439 rare or extremely rare) and may, therefore, have a yet unknown disease-causing effect. The same is true for 19.0% (n = 6266) of variants of unknown clinical significance or conflicting interpretation reported in the ClinVar database. The results of the structural analysis are available in the dedicated web catalogue Missense3D-DB (http://missense3d.bc.ic.ac.uk/). For each of the 4 M variants, the results of the structural analysis are presented in a friendly concise format that can be included in clinical genetic reports. A detailed report of the structural analysis is also available for the non-experts in structural biology. Population frequency and predictions from SIFT and PolyPhen are included for a more comprehensive variant interpretation. This is the first large-scale atom-based structural interpretation of human genetic variation and offers geneticists and the biomedical community a new approach to genetic variant interpretation.

Remote sensing image transformation with cosine and wavelet method for SPACeMAP Visualization

Remote sensing imagery in LAPAN has been managed and distributed through many media and device, like CCT, DCRSy, tape, CD, DVD, hard drive. The format is available from Quicklook data (in JPG or BMP), data RAW (in Gtiff or ground station data format). There also exist metadata that bring along in each remote sensing data like Landsat data, SPOT, Radar data, and High-resolution data. From that all collection then it would need some system that can arrange, keep and distribute data in a huge amount of number. Research on metadata structure and standard will be required in managing a large number of remote sensing data. Types and formats from those remote sensing data will be various but the raster format which most widely used is GeoTiff. Metadata for every raster data format is already standardized following the rule of ISO 19139 and 19115. SPACeMAP is a new web catalog system that uses the simplest and latest raster data format for displaying the mosaic image, data processing result, data raw format and etc. The structure of raster data format (like Gtiff and ECW) is very flexible although the format needs certain criteria. Metadata also treated the same as raster format, this treatment hopefully will minimize the error.

Estimating Conformational Traits in Dairy Cattle With DeepAPS: A Two-Step Deep Learning Automated Phenotyping and Segmentation Approach.

Assessing conformation features in an accurate and rapid manner remains a challenge in the dairy industry. While recent developments in computer vision has greatly improved automated background removal, these methods have not been fully translated to biological studies. Here, we present a composite method (DeepAPS) that combines two readily available algorithms in order to create a precise mask for an animal image. This method performs accurately when compared with manual classification of proportion of coat color with an adjusted R2 = 0.926. Using the output mask, we are able to automatically extract useful phenotypic information for 14 additional morphological features. Using pedigree and image information from a web catalog (www.semex.com), we estimated high heritabilities (ranging from h2 = 0.18–0.82), indicating that meaningful biological information has been extracted automatically from imaging data. This method can be applied to other datasets and requires only a minimal number of image annotations (∼50) to train this partially supervised machine-learning approach. DeepAPS allows for the rapid and accurate quantification of multiple phenotypic measurements while minimizing study cost. The pipeline is available at https://github.com/lauzingaretti/deepaps.

Fast and Wide CMEs without Observed >20 MeV Protons

Abstract Statistical studies have found a close association between large solar energetic particle (SEP) events and fast and wide coronal mass ejections (CMEs). However, not all fast and wide CMEs have an associated SEP event. From the Coordinated Data Analysis Web catalog of CMEs observed by the Solar and Heliospheric Observatory (SOHO) between 2009 January 1 and 2014 September 30, we select fast (plane-of-sky speed >1000 km s−1) and wide (plane-of-sky angular width >120°) CMEs and determine whether >20 MeV protons were detected by either SOHO or the Solar TErrestrial RElations Observatory (STEREO-A or STEREO-B). Among the 123 selected CMEs, only 11 did not produce a >20 MeV proton intensity increase at any of the three spacecraft. We use multispacecraft coronagraph observations to reevaluate the speeds and widths of the CMEs. The 11 CMEs without observed >20 MeV protons tend to be in the narrow and slow end of the distribution of the selected CMEs. We consider several factors that might play a role in the nonobservation of high-energy particles in these events, including (1) the ambiguous determination of the CME parameters, (2) the inefficiency of the particle sources to produce >20 MeV protons, (3) the lack of magnetic connection between particle sources and any spacecraft, and (4) the lack of particles accelerated and released during the parent solar eruptions. Whereas the extent of the high Mach number regions formed in front of the CME is limited, the characteristic that seems to distinguish those fast and wide CMEs that lack observed >20 MeV protons is a deficit in the release of particles during the solar eruptions.

Ecotaxonomy: Linking traits, taxa, individuals and samples in a flexible virtual research environment for ecological studies

Major research progress in ecology is being achieved through large-scale collaborations across people, groups and countries. In large-scale projects harmonization of data is tedious and time-consuming, but needs to be done reliably and rapidly. This is especially true if projects investigate under-explored organism groups such as tropical invertebrates. To link taxa to their role in ecosystems, functional traits of the taxa need to be considered. However, despite the urgent need for a common database for invertebrate traits, this is yet to be established. We developed an open web platform, Ecotaxonomy (ecotaxonomy.org), that allows traits, taxa, individuals and samples to be linked within research projects. Ecotaxonomy includes a virtual research environment, allowing project members to work jointly online on the data input, integration and retrieval. The taxonomic system of Ecotaxonomy is based on the Global Biodiversity Information Facility (gbif.org), but may be complemented by morphospecies, pictures, literature and other parameters. Any parameters can be customized inside the system and attached either to taxa, individuals, or environmental samples (Fig. 1). As public output, the system provides interactive identification keys and web catalogs of traits and taxa. Ecotaxonomy is implemented on GCore platform, that is being developed by Complex Cloud Solutions (http://ccs.msk.ru/en/). The GCore is based on Node.js, allowing for fast and efficient standardised programming. Thus, custom modules can be implemented in the future by external developers in the framework of the platform. Ecotaxonomy is now open for beta-testing. After a public release (presumably in 2020), our goal is to keep the system and the code open and ensure data interoperability via Darwin core standards. The initial stage of Ecotaxonomy development (2016-2023) is funded in the framework of a DFG-funded project (SFB 990). To ensure long-term sustainability, we are involving ecological laboratories around the world and ultimately seek to establish a permanent funding by governmental or non-governmental organisations. Using and developing Ecotaxonomy, and linking it to existing open repositories will greatly improve the efficiency and integration of research in trait-based ecology.

Act 2 for chemical e-commerce

Count e-commerce in the chemical industry among the flops of the dot-com boom and bust. Not that the major chemical companies didn’t make a go of it, individually and in partnerships, in the early 2000s. But efforts to launch Amazon-like web catalogs for buying and selling chemicals petered out quickly; the companies that remained in business pivoted to developing online logistics tools and other services. It seemed that trade in chemicals—more involved than selling books and consumer items—was too complex an undertaking for the shiny new thing called a web portal. Nowadays, however, people buy Porsches online. Businesses are thoroughly acclimated to cloud computing, and web services have matured to the point at which once-complex transactions are routine. So chemical purveyors are trying again. In recent months, several web platforms have emerged for selling chemicals via online catalogs. This time, executives maintain, the chemical industry is ready to make e-commerce

Implementing a Proactive Chat Widget in an Academic Library

Sometimes users need to be asked if they need help. This is difficult with online users, because in-person cues cannot be used to engage when the users need assistance. Proactive chat widgets help to solve this problem as the chat box slides out onto the screen and prompts the user for help. The need for the proactive chat widget was also seen as EZproxy data revealed only 1% of online students who accessed the library’s resources reached out for help through chat. This article will cover the successes and challenges of implementing a proactive chat widget on the library’s Web site, catalog and databases; the review of proactive chat software; the collaboration of departments within the library to test and launch the widget; chat transcript analysis for coverage and training; and roles of the different departments staffing the chat service.

Assessing Web Services Interfaces with Lightweight Semantic Basis

In the last years, Web Services have become the technological choice to materialize the Service-Oriented Computing paradigm. However, a broad use of Web Services requires efficient approaches to allow service consumption from within applications. Currently, developers are compelled to search for suitable services mainly by manually exploring Web catalogs, which usually show poorly relevant information, than to provide the adequate glue-code for their assembly. This implies a large effort into discovering, selecting and adapting services. To overcome these challenges, this paper presents a novel Web Service Selection Method. We have defined an Interface Compatibility procedure to assess structural-semantic aspects from functional specifications - in the form of WSDL documents - of candidate Web Services. Two different semantic basis have been used to define and implement the approach: WordNet, a widely known lexical dictionary of the English language; and DISCO, a database which indexes co-occurrences of terms in very large text collections. We performed a set of experiments to evaluate the approach regarding the underlying semantic basis and against third-party approaches with a data-set of real-life Web Services. Promising results have been obtained in terms of well-known metrics of the Information Retrieval field.

OJS Implementation and development of the Scientific Journals Site of the School of Humanities and Education Sciences of the Universidad Nacional de La Plata

This article describes how the journal site of the School of Humanities and Education Sciences at the Universidad Nacional de La Plata was implemented and developed, so that our experience may be useful for anyone embarking on a similar undertaking. We first review the experience of the School in terms of scientific journal publication and the tasks performed by the Library to help its visualization. Secondly, we mention the work of the Under-Secretariat of Publication Management and Dissemination (PGEyD; its acronym in Spanish) of the School to make launching the site a reality. Special reference is made to software customization, massive information upload to the system (users and previous issues), and the procedures that enable the semi-automatic inclusion of the site content in the institutional repository and in the Web catalogue. Then, we discuss the work that is being carried out in connection with editors’ training and support, and the results obtained after one year of labour: the creation of 10 journals, the migration of the entire works of four titles and the inclusion of 25% of the contributions published in the journals edited by FaHCE. Finally, we point out a series of challenges that the Under-Secretariat has set itself to improve the site and to optimize intra- and inter-institutional workflow.

Evidence of self-organization in Sumatra earthquakes: recurrence time and its geodynamical implications

Inter-event time series of seismic activities of Sumatra region with magnitude (m b ≥ 4.8) and period spanning over 1973–2012 has been analyzed using the techniques of nonlinear dynamics. The earthquake data were collected from the USGS Web catalog. The rank order statistics of inter-event time series reveal mixed response with distinct breaks in slope suggesting that earthquake dynamics in this region are unstable, but “self-organized.” Comparison of return maps of the data with random, stochastic, and chaotic time records shows quasi-deterministic behavior. We assessed the dimensionality of earthquake-generating mechanism using a nonlinear predictor technique on two-dimensional phase portrait constructed by recurrence time series. The nonlinear forecasting analysis suggests that the earthquake processes in the Sumatra region evolve on a non-random low-dimensional chaotic plane. Further, second-order Kolmogorov entropy “K2” analysis revealed a coherent time structure, indicating quasi-deterministic dynamical pattern. Our result is consistent with “self-organized” processes determined by the internal dynamics, where impulsively derived interdependencies cascade through the tectonic stress generated by plate movement. However, we do not preclude the triggering role of other external processes on the coupled underlying system.

Service Oriented Architecture Based SDI Model for Mineral Resources Management in India

Today’s economic growth rate of any country hugely depends on development of the mining sector. Thus, the level of technology employed for meeting the extraction conditions must meet environmental norms. Exploration of mineral resources in India and mining is a ready application for technologies for ensuring productivity and efficiency. Mineral resources management uses Spatial Data Infrastructure (SDI) in the study reported. SDI is a portal where each stakeholder can access, use and exchange spatial and non-spatial data for social, economic and environmental activities. The proposed system at national level may have its nodes at state level and local level on Intranet and/or Internet on Global level. The present work reports the development of an efficient interoperable Service Oriented Architecture (SOA) based SDI Model for mineral resources management in India (Acronym: MRII (Mineral Resources Information Infrastructure)) to provide better geospatial web services for different applications in terms of their functionality, ease of operation and performance as applied in various mineral resources management systems. The MRII is modular. It allows the publishing of web service descriptions as well as to submit requests to discover the web services of user’s interests. The model supports integration of applications and uses thin-client architecture. Web Map Service (WMS), Web Features Service (WFS) and Web Catalogue Service (CS-W) of Open Geospatial Consortium (OGC) standards have been used for sharing and exchange of geospatial data in MRII. The open source GIS software, used for development of MRII, include Quantum GIS for creation of mineral resources geospatial database, PostGIS for storing of spatial database, MYSQL for storing of security aspects of spatial and non-spatial data; ALOV, GeoServer, GeoNetwork, GeoWebCache and Apache Tomcat for imparting geospatial web capabilities and PHP (Hypertext Preprocessor), JSP (Java Server Pages) and GeoExt (Geo Extension) for dynamic server side scripting. The developed MRII presently provides detailed information about mineral resources in India as a test case and aims to deliver spatial information at affordable cost. The same may be used in future for other countries on expanding the volume of spatial data to include the Globe.

How to Implement a Governmental Open Source Geoportal

By emerging the OGC web services technologies which caused server interoperability in geospatial fields, a rush toward implementing geoweb services commenced among most governmental enterprises. The massive geospatial information which has been produced in various offices during previous years, and which was not available for public customers because of protocol difficulties, now had a chance to be restructured as OGC specifications and be reachable to huge amount of keen clients via Internet platform. Increasing number of map presenters in web environment raised a search facility requirement in spatial data area. These kinds of search abilities are called “Geoportal”, which provides client applications that use several geo services such as catalogs and web map services. How to implement a suitable geoportal to meet the needs, has brought a set of hard challenges for governmental geospatial owners. In this study we present an overall concept of service oriented architecture and its consequence web service specifications and eventually web catalog services which are fundamentals of developing a geoportal. It also declares some experiments on importing/exporting data between geoportals, which is known as harvesting method.

Bibliographic Displays and Web Catalogues: Responding to User Preferences

The development of these prototypes builds upon results obtained in earlier phases of the project that addressed issues of both the content and form of bibliographic displays in Online Public Access Catalogues. . .

Perceptions of Librarians Regarding Semantic Web and Linked Data Technologies

In recent years, a growing level of attention has focused on Semantic Web technology and its potential application to the library catalog. Despite growing interest in the topic, it is unclear where perceptions currently are regarding the Semantic Web and linked data in the academic library community. This paper aims to ascertain levels of understanding of key concepts and attitudes regarding the Semantic Web and its role in the library catalog, with the hope of highlighting directions to move forward for advocates of the technology. To find the attitudes and perceptions of academic librarians, a survey of academic library catalogers and technical services professionals was created and distributed online. This paper found that an understanding of key terms and interest in the development of a Semantic Web catalog are high among the queried group, but barriers such as financial scarcity and lack of Semantic Web best practices may slow future development.

“Linked data” – dados interligados - e interoperabilidade entre arquivos, bibliotecas e museus na web

http://dx.doi.org/10.5007/1518-2924.2012v17n34p171 Catálogos Web em sistemas de arquivos, bibliotecas e museus são hoje recursos informacionais fechados, usando tecnologias, padrões e interfaces de próprios, não permitindo navegar de outros recursos para dentro dos catálogos e vice-versa.
