Elementary students use the Web to find information, but can encounter problems with keyword searching. An alternative is to choose terms from a taxonomy (subject directory), but students may then encounter problems in locating a term within the taxonomy. This paper reports on a comparative analysis of a conventional, hierarchically displayed taxonomy with a display of the same taxonomy using information visualization techniques. The evaluations were undertaken by students from grade-six (11 to 12 years’ old) and are part of a larger study on the application of information visualization techniques to interfaces targeted at children.Les élèves du primaire utilisent le Web pour trouver de l'information, mais peuvent avoir des difficultés avec la recherche par mots-clés. Une possibilité serait de choisir des termes à partir d'une taxonomie (liste de sujets), mais dans ces circonstances, ils pourraient avoir de la difficulté à localiser le terme voulu. Cet article présente l'analyse comparative d'une taxonomie hiérarchique conventionnelle et de la même taxonomie présentée en utilisant des techniques de visualisation de l'information. Les évaluations ont été effectuées par des élèves de 6e année (11 et 12 ans) et font partie intégrante d'une étude plus vaste sur l'application de techniques de visualisation de l'information dans la conception d'interfaces ciblant les enfants.

Visualization Techniques

Learning Management Systems (LMS) may use Information Visualization techniques and concepts for presenting their large amounts of data, in order to ease the monitoring and analysis of students learning process problems. Nonetheless, the generally adopted approaches are based on presenting data obtained by predefined database queries only, which does not consider unforeseen situations derived from final user’s knowledge about e-learning domain. Therefore, the purpose of this work is to provide a resource for LMS users to define and execute queries related to these unforeseen situations. This resource is a prototype by which users may access a remote LMS database, create their own queries by selecting database attributes they want to analyze, and represent query results by means of automatically selected interactive graphical representations. User evaluations indicate that the approach is appropriate and points out possible enhancements.

This paper undertakes a comparative analysis of the visibility, and of other SEO indicators, of the culture sections of Spain’s leading digital newspapers —specifically, elmundo.es, elpais. com, lavanguardia.com, abc.es, el­confidencial.com and 20minutos.es— based on data collected by the media analytics company, comScore, and the web traffic metric, Alexa Rank. The analysis employs a set of positioning in­dicators: namely, a visibility index, keywords, social signals, keyword profiles, URLs, SERP-Snippets, reference domains and best anchor texts, as made availa­ble by SISTRIX, an SEO analytics audit toolbox. Thus, we were able to deter­mine which of the digital newspapers’ culture sections has the best visibility. Likewise, we were able to identify which of these media are best positioned on Google, presumably as a result of more effective positioning strategies. We con­clude with a discussion of our results and, on the basis of these findings, re­commend ways in which the visibility of journalistic information can be optimi­sed in search engines.   SEO i cibermitjans: visibilitat de la informació cultural dels principals diaris d’Espanya Aquest article realitza una anàlisi com­parativa de visibilitat i altres indicadors SEO de la secció de cultura dels principals cibermitjans espanyols: elmundo.es, elpais.com, lavanguardia.com, abc. es, elconfidencial.com i 20minutos. es. Les anàlisis s’han dut a terme amb la utilització d’un conjunt d’indicadors de posicionament (visibilitat, paraules clau, senyals socials, paraules clau, url, snippets, dominis de referència i mi­llors textos àncora) utilitzant l’eina de auditoria i anàlisi de posicionament en cercadors, SISTRIX. Ens preguntem quin d’aquests mitjans té millor una secció de notícies culturals amb millor visibilitat. L’estudi dut a terme amb els indicadors seleccionats permet, d’aquesta manera, presentar una anàlisi comparativa del periodisme cultural i identificar quins d’aquests mitjans presenten millors posicions a Google, presumiblement, com a resultat d’estratègies de posicio­nament. Finalitzem amb una discussió dels resultats juntament amb unes re­comanacions finals per optimitzar la vi­sibilitat de la informació periodística en els cercadors.

Data communication in the internet today is so complex as an example of the speed factor becomes very important in communicating, everyone wants fast data communication services provided in order to maximum. In relation to the application as a communication liaison with client server applications, web service using a data serialization format to transmit the data. Before the data is sent, either fromthe client to the server or vice versa, should be modified in a specific data format beforehand according to the web service is used. Types of data serialization format used in the web service such as XML and JSON. The method used for testing include data serialization method, data measurement method and data parsing method. Data serialization method is used to calculate the time serialization of data from the database to the form of XML and JSON in applications with PHP platform. Data measurement method used to measure the size of the XML and JSON data which based on many fields of data serialization process. Data parsing method is used to calculate the processing time and JSON parsing XML data. Results o f comparative analysis o f XML and JSON in PHP applications using thearchitecture Rest can be concluded that the test result o f the difference in time and time serialization and JSON parsing XML data is influenced by the number o f records, if the number of records the greater the difference in eating time data serialization and parsing the data the greater the time also itcan be concluded that the faster the process JSON serialization and parsing XML data is compared. Testing results o f the JSON data size is smaller than the size of XML. Data exchange using XML format has a size limit of up to 31456.31 KB while JSON XML exceeds the size limit. Testing results on the Internet when the number o f records up to 50,000 data when the data serialization and parsing time data can not be detected in the database.

In the academic literature and the business press, there seems to be a lack of guidance and lack of cross-cultural models to support companies localization strategies on the Web. To address this deficit in literature and to provide marketers and Web designers with insights into website localization, this paper conducted a comparative analysis of the U.S. based international companies’ domestic websites and their Chinese websites. A framework to measure cultural adaptation on the Web is presented. Forty U.S.-based Fortune 500 companies are surveyed to investigate the cultural adaptation of their Chinese websites. Content analysis of the 80 U.S. domestic and Chinese websites reveals that the web is not a culturally neutral medium, but it is full of cultural markers that give country-specific websites a look and feel unique to the local culture.

The Web

In general terms, a portal can be seen as “a door, gate or entrance” (Macquarie Library, 1981), and in its simplest form the word just means a gateway; however, it is often a gateway to somewhere other than just to the next room or street. The Oxford Reference Dictionary defines a portal as “a doorway or gate etc, especially a large and elaborate one” (Pearsall & Trumble, 1996). In the context of this article, a Web portal is considered to be a special Internet (or intranet) site designed to act as a gateway to give access to other specific sites. A Web portal can be said to aggregate information from multiple sources and make this information available to various users (Tatnall, 2005c). It consists of a Web site that can be used to find and gain access to other sites, but also to provide the services of a guide that can help to protect the user from the chaos of the Internet and direct him or her toward a specific goal. More generally, however, a portal should be seen as providing a gateway not just to sites on the Web, but to all network-accessible resources, whether involving intranets, extranets, or the Internet. In other words, a portal offers centralised access to all relevant content and applications.
