The process of creating a cartography, an interactive visualization, from the bibliographic data of the contents of the scien- tific journal Profesional de la información during its almost 30 years of life is presented. The cartography is available on the EPI journal website: https://profesionaldelainformacion.com/cartografia/EPI_GLOBAL/index.html. Its objective is to serve as a navigable index for the quick localization of information of interest to readers as well as a visual map that highlights the characteristics of the knowledge network that these data form through the interconnection of relationships between its nodes. This device has been created by extracting data from the journal's website using web scraping tools and the free software Gephi for network visualization. A graph viewer allows access and manipulation through the web. Navigation through the bibliographic data network is facilitated by different strategies: (1) the use of different colors for each category of node (author, keyword, number, and article); (2) the viewer's search tools, including a node label finder, a zoom bar, a magnifying glass, and a button to hide the network of relationships; and (3) the possibility of displaying different linked graphs. Selecting a node opens a side-space where all the attributes providing information about that node are displayed and that enables a new window to be opened, displaying all the information linked to an external page. The information on the authors is obtained from the Directory of Experts in the Management of Information (EXIT). This tool thus undeniable provides a useful source of secondary information on the journal, as were printed indexes in their day, with the advantage that it can be updated almost simultaneously with the publication of new issues. The data obtained will be used to carry out other analyses of the evolution of the journal, the topics of interest to the profession, and its stakeholders. [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]

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]

The Histocarto project aims to create a geoportal where potential users can enjoy in an easy, comfortable and intuitive way, part of the historical cartographic and photographic heritage of the city of Granada, focusing mainly on urbanism and landscape. The retrieval of this kind of documents nowadays is not effective in other institutional webs, in profiles of social networks or in personal web sites. Through the appropriate methodology that includes: location, selection, digitization, description, georeferencing (cartography) and geolocation (photography), tiling and web publication. As a result we have obtained a geoportal or cartographic visualizer where we can carry out traditional textual searches improved with filters, more intuitive geographic searches, past-present comparison of documents, and link document.

The design and characteristics of a new open source content aggregation program, AXYZ, are described. Several features of the program standout, including the processing engine of syndication channels, monitoring capability of information recovery in real time, possibility of configuration of the aggregator behavior, automatic content classification, and new models for representing information from relational interactive maps. On the other hand, the aggregation program is designed to manage thousands of syndication channels in the RSS format. It also provides statistics that can be used to study the production of any information producer and the impact of the information published in other sources. The AXYZ modules are capable of comparing the relationship between news or information from different sources and the degree of influence which is detected by patterns. [ABSTRACT FROM AUTHOR]

The possibility of constructing science maps based on co-use of scientific literature by academic users is explored. We define co-use as the co-occurrence of scientific information requests by pairs of users recorded in platforms of scientific journals. We used search data from the University of Navarre to the ScienceDirect platform in 2012 in order to test the validity and to analyze the possibilities of this methodological approach. We conclude by emphasizing the viability of this methodology when exploring the research interests of an academic institution along with the relations among different disciplines.

The hashtag, a phrase that is highlighted by preceding it with a hash symbol (#), is already 6 years old. People use it on a massive scale in social media, with two objectives: to tag (or label) conversations and content, and to identify communities. It can be used also as a rhetorical element in activism, marketing, or just for amusement. Recent research highlights its value as a predictive system and for engaging the TV audience using Twitter. Some national and academic libraries are storing and preserving hashtags for future research. [ABSTRACT FROM AUTHOR]

The evolution of the information retrieval discipline has not been sensitive to developing the display of results. In many cases, the results presentation is as important as the selection of the retrieved documents in satisfying the user's information needs. However, it is possible to identify a number of standard models and certain trends in the visual presentation of results in a retrieval system. This study analyzed the patterns and trends and established a series of requirements (architectural and semantic) as a guide for improving the functionality of visualization tools in the retrieval processes.

Although many analogic audiovisual archives are still awaiting a digitization project that guarantees their preservation and public access, a massive generation of audiovisual content is taking place, once the source has completed the transition to digital production and distribution. The demand for an increasingly diversified production at TV stations is leading to the need to prioritize image retrieval from the archives for reuse. Efficient alternatives for automatic metadata extraction, indexing and searching are sought, and text information to describe images continues to be necessary. The documentary image processing is extremely costly in human resources, with dedication times of two, three or even more times the length of the treated material. In parallel, part of the audiovisual production is indexed during the production process by people other than archivists, librarians or information scientists. Therefore, a transformation of the traditional tasks carried out by the above mentioned professionals is becoming more evident; on the other hand, these professionals continue to be isolated and less hybridized than expected with other labor profiles.

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.

Obtaining information in short periods of time can make the difference for research or business; therefore it is important to have tools that facilitate the search for information. A visualization technique called information-clustering engine is reviewed: Carrot2 separates the documents found on the Web into groups or clusters, using clustering algorithms that consult various sources of data and then process and display the information obtained. This open-source software significantly reduces the effort involved in information retrieval (IR) and analysis. [ABSTRACT FROM AUTHOR]

Mobilised opinion and social media have become a valuable source of information for organisations and individuals in operational and strategic decision making processes, such as marketing campaigns, product monitoring and development, search for new markets or the improvement of customer relations. The emergence of social media monitoring companies has brought a new job market for information professionals, to the extent that this information has to be collected and processed, and new automated monitoring systems have to be developed. This article outlines a process of recovery and treatment of mobilised opinion on the internet as a source for social climate analysis by organisations. The specific characteristics and problems of this type of opinion are highlighted, which points to the need for the participation of human agents in the development of the process.

We present the theoretical and methodological basis of a model that offers the managers information about their own social networks. We analyzed the nursing directors social networks of hospitals belonging to the Network of Hospitals for Public Use (XHUP) of Catalonia, Spain, and studied the information retrieved from these networks. The proposed model is applied to make a comparative analysis of managers surveyed, in order to improve strategies and to enhance outcomes of competitive intelligence projects. [ABSTRACT FROM AUTHOR]

A study based on Google and Yahoo! page results using eye tracker technique is presented. Participants (n=58) attempted informational, navigational, transactional or multimedia tasks. Sessions were recorded with an eye tracker to determine whether the intention behind queries affects the way people browse the results page. Eye fixations in title, snippet, url and images were analyzed in the three first organic and sponsored results. In general terms, the results demonstrate that a relationship exists between the users' intention and their behavior when they browse the results page. Knowing this behavior is important for search engine designers because they can improve their results pages depending on the users' query intentions. [ABSTRACT FROM AUTHOR]

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]

The Web of Science interface counts at most 100,000 retrieved items from a single query. If the query results in a dataset containing more than 100,000 items the number of retrieved items is indicated as >100,000. The problem studied here is how to find the exact number of items in a query that leads to more than 100,000 items. One way to achieve this objective is presented. The retrieval of the entire scientific production from the United States in a specific year (2007) is counted and an advanced search strategy is designed. Different sections of items can be retrieved using the Source field of the database. A Boolean statement was created with the aim of eliminating overlapped sections and improving the accuracy of this search strategy. [ABSTRACT FROM AUTHOR]

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.

We present a review of some of the main trends in research on web genres. Genres are documents defined primarily by the communicative purpose they accomplish for their producers and recipients, though they also present specific characteristics of topic and form. Thinking of web documents in terms of genres provides a selection criterion which is complementary to topic or subject and which can also be implemented in automatic classifiers. The review offers a definition of web genres, a summary of achievements in automatic classification of web genres, and a perspective from which to sort out the increasing number of contributions on genres.
