Access to public information (that generated by public institutions) is a right recognized by both European (Unión Europea, 2001) and Spanish legislation (España, 1992; 1997; 2013). The bodies of the Spanish State must to make available to the citizens, free of charge and in a transparent way, all the documents that they generate, unless there are national security reasons. Many national, regional and local governments have created information systems or public information platforms in the form of newsletters or gazettes. The purpose of this paper is to find out how is, on a documentary level, the main informative gazette of Spain, the Boletín oficial del Estado (BOE). The metadata of the published documents are studied and the metadata used for documentary description are analyzed in a deeper way. The results reflect the absence of documentary descriptors in more than 89% of the total documentary BOE' corpus. In recent years this figure has barely exceeded 50%. The paper ends with a few recommendations for improvement. [ABSTRACT FROM AUTHOR]

This paper presents an analysis of the publication of datasets collected via Google Dataset Search, specialized in families of RNA viruses, whose terminology was obtained from the National Cancer Institute (NCI) thesaurus developed by the US Department of Health and Human Services. The objective is to determine the scope and reuse capacity of the available data, determine the number of datasets and their free access, the proportion in reusable download formats, the main providers, their publication chronology, and to verify their scientific provenance. On the other hand, we also define possible relationships between the publication of datasets and the main pandemics that have occurred during the last 10 years. The results obtained highlight that only 52% of the datasets are related to scientific research, while an even smaller fraction (15%) are reusable. There is also an upward trend in the publication of datasets, especially related to the impact of the main epidemics, as clearly confirmed for the Ebola virus, Zika, SARS-CoV, H1N1, H1N5, and especially the SARS-CoV-2 coronavirus. Finally, it is observed that the search engine has not yet implemented adequate methods for filtering and monitoring the datasets. These results reveal some of the difficulties facing open science in the dataset field. [ABSTRACT FROM AUTHOR]

The number of papers written on ontologies has increased considerably over the last twenty years. This trend can be easily observed by searching words like "ontology" or "thesaurus" in databases. Despite this fact, there hasn't been a consensus about the significance of this concept. The graphical representation known as ontology spectrum must have generated a lot of confusion amongst readers. In this paper we argue that this confusion is due to the mix of the various types of knowledge organization systems with distinct objectives in the same graphical representation. Thus, constructing a formal ontology for a system does not always presume an improvement, frequently it is adequate with less complex representations. [ABSTRACT FROM AUTHOR]

This paper proposes an original model of the visual information retrieval interface (VIRI), aimed at websites described by metadata. The paper also describes the development of an experimental prototype based on the proposed model. The applied methodology for the prototype's development is a combination of three methods: Metadata mining, Multidimensional scaling (MDS), and a Focus+Context technique called Fisheye. Finally, a user test is conducted, whose results suggest that the proposed model of VIRI is useful for information browsing and retrieval, and is satisfying for the end–user as well.

Technological advances in the field of information and interactive systems mean that increasing numbers of factors and criteria are considered to assess quality during the design, development and evaluation process. In this context, concepts such as quality of use and user experience have appeared and in many cases are replacing or supplementing existing usability properties to identify the quality of the interaction process. In this paper we describe and analyze the evolution of the different concepts to identify the quality of the interaction on information systems and we help to characterize and locate each quality factor in one dimension and a specific range of the process of use, and consider the relationships and overlap between these concepts.

Question answering (QA) applications can be considered as the potential successors to the traditional information retrieval on the Web. However, QA systems should be adapted to restricted domains for the sake of precision. This adaptation is not a trivial task, since several heterogeneous resources related to a restricted domain must be integrated into existing QA systems. This paper presents the Maraqa tool, whose novelty is the use of software engineering techniques such as model driven development to automate the adaptation process. It is worth noting that Maraqa has been evaluated through a set of experiments (within the agricultural domain) that demonstrate its applicability: the precision of the adapted QA system showed 29.5% improvement.

This paper analyzes the relationship between motivation and time estimates spent on internet based tasks, and its eventual incidence in informational and dialogical activities. The sample consisted of 120 students from 7 schools ("liesceos") in Chile, whose average age was 15. The participants had to carry out two different tasks on the Internet: first, a vertical communication activity (Google search); second, a horizontal communication activity (messaging). In each task, the perceived elapsed time and the level of interest were evaluated. When comparing the vertical and the horizontal communication activities, the results show a significantly higher interest and significantly lower estimated time in the horizontal communication task (chatting). From these results, a projection of the informational and educational uses of the internet can be made. [ABSTRACT FROM AUTHOR]

Evaluating the Information Architecture in an already deployed website is not an easy task. Most evaluation techniques are focused on examining system usability, but this is not the only factor that influences IA. The main technique that deals with IA in already deployed web environments is the Navigation Stress Test (NST). A new methodology makes this technique more informative by taking NST beyond simple notation on paper. This work proposes the use of NST combined with other usability testing techniques such as Thinking Aloud and a usability questionnaire. Eye tracking also has been used to supplement the information obtained from applied techniques. This new methodology has been tested by analyzing a series of websites belonging to Spanish public university libraries. The results of this study show the validity of the approach used, as well as the value that this approach and the use of Eye tracking bring to the analysis of IA compared to traditional NST.

The planning and design of a web site information architecture necessarily involves a prototype proposal for the architectural structure of the informational environment. The aim of this paper is to analyze and evaluate a range of tools that facilitate the development of the wireframes in the design and creation of web sites. [ABSTRACT FROM AUTHOR]

Information has increasingly become a crucial resource for organizations that want to remain competitive in the market. For this reason, analysis and a correct understanding of informational types that are present in these environments become relevant to achieving the highest levels of performance. The aim of this paper is to review the literature of the concepts of organic and archival information within the organizational context/business environments. This is still an emerging theoretical field and therefore is conducive to intense discussions. We point out elements that help to characterize and distinguish these two types of information.

Certainly, in recent years there has been a breakthrough in regard to web accessibility: policies and laws have emerged, along with tools, technologies and guidelines for creating accessible content properly. However, despite these efforts, the Web is still largely inaccessible. In this paper we have analyzed the different technical options for implementation of systems of linear access to the websites, systems which greatly facilitate the accessibility and the usability of these pages and are often forgotten by developers.

The terminology used in biomedicine has lexical characteristics that have required the elaboration of terminological resources and information retrieval systems with specific functionalities. The main characteristics are the high rates of synonymy and homonymy, due to phenomena such as the proliferation of polysemic acronyms and their interaction with common language. Information retrieval systems in the biomedical domain use techniques oriented to the treatment of these lexical peculiarities. In this paper we review some of these techniques, such as the application of Natural Language Processing (BioNLP), the incorporation of lexical-semantic resources, and the application of Named Entity Recognition (BioNER). Finally, we present the evaluation methods adopted to assess the suitability of these techniques for retrieving biomedical resources. [ABSTRACT FROM AUTHOR]

Google Scholar is a search engine that specializes in scientific information and in the identification of the citations that academic papers receive, making it a strong competitor for other citations indexes. For this reason, several studies have attempted to evaluate its capacity as a bibliometric tool. Due to this interest, we present an introduction to its use and the advantages and disadvantages versus Scopus and Web of Science. First, its way of collecting information and features of its interface are analyzed. The following section describes the results that Google Scholar generates. Thirdly, we analyze the coverage of information sources and the different document types to be found, showing how this coverage universe offers different citations versus other products. Finally, we specify the standardization problems of Google Scholar and offer a number of precautions that must be taken into account when using Google Scholar as an evaluation tool.

Improvement of the interfaces and search capacities of the opacs continues to be one of the main challenges for libraries, especially with regard to searching by subject. The visual interfaces can help with retrieval. This paper explores the combination of co-term analysis techniques with social networks for the generation of subject maps of collections. The main conclusion is that the methodology applied is valid, and that the maps could be used for browsing and subject retrieval. It would also be useful for improving the quality of indexing.

This paper shows how the individual study of different basic attributes from a web resource is not enough to infer different positioning strategies for search engines. The fundamental question is about the relation between the different elements that compose the page and the importance that each of them contributes to the final positioning. As an alternative to this problem, we propose the use of inductive learning techniques, more concretely, sort trees. Results are reflected in two experiments, the outcome of two different learning algorithms. As a final result, we conclude that the application of this technique can be a very promising starting point for optimising web positioning. [ABSTRACT FROM AUTHOR]

This paper analyses the different positioning strategies according to their ability to obtain an optimum recall level. The analysed positioning strategies are the search for terms in the title, in the url, in the links, or in the Meta and Head tags. Our analysis is restricted to non-commercial pages--commercial pages are avoided because of their policies for achieving greater popularity by means of web optimisation-. The specificity level of the query is taken into account. We submitted thirty queries to four search engines (AskJeeves, Google, YahooSearch, and MSN); then we judged by hand the relevance of the first twenty hits of each query. Our analysis yields the following findings: the utility of the title strategy; the need for analysing the data by function of the type of query; and the suitability of designing new retrieval measurements. These measurements should take into consideration the relevant documents without the strategy, as well as those non-relevant documents with it. [ABSTRACT FROM AUTHOR]

The vast and growing number of web resources show that lexical-statistical aids by themselves cannot resolve the problem of information retrieval. The "semantic web" project tries to solve these problems (and to do much more) by having the computers comprehend the content of the resources. This paper examines the current status of the required layers' put forward by Berners-Lee for the development of the Semantic web: namely, the uniform identification layer, the representation layer, the logical layer, and the security layer.
