Análisis de software de analítica web para medir uso de recursos y servicios electrónicos de bibliotecas universitarias

Las bibliotecas universitarias recopilan, de manera rutinaria estadísticas sobre el uso de sus colecciones impresas y de la actividad in situ. Paralelamente y de manera sostenida, han ido incorporando recursos y servicios electrónicos, lo que ha motivado la elaboración de normas internacionales que definen indicadores que permiten medir su uso, no obstante contar con un software estándar es aún un asunto pendiente. Por otro lado, para medir la actividad de un sitio web existen varios programas gratuitos y de código abierto. Este trabajo tiene como objetivo determinar si los softwares de analítica web gratuitos para sitios web AWStats, Google Analytics y Piwik, pueden utilizarse para evaluar el uso de recursos y servicios electrónicos, conforme a los indicadores propuestos por las normas ANSI/NISO Z39.7-2013, ISO 2789:2003, ISO 20983:2003, BS ISO 11620:2008, EMIS, Counter e ICOLC. Para tales efectos, fueron utilizados para realizar el análisis de esta investigación sitio web y el catálogo en línea de la Biblioteca Florentino Ameghino, Biblioteca Central de la Facultad de Ciencias Naturales y Museo de la Universidad Nacional de la Plata, Argentina. Los resultados reflejan las características de los indicadores, el software y el caso de estudio. Estas características son abordadas en las conclusiones con el fin de darle contexto y perspectiva a la respuesta de la pregunta de si es viable medir el uso de recursos y servicios electrónicos de una biblioteca universitaria por medio de programas estadísticos para sitios web

Using Statistics to Set Priorities

In November 2015-March 2016, I assigned my Graduate Assistant, David Durden, a project to compile usage statistics and trends for digitized collections between 2013-2015 from UMD Digital Collections and our contributions to the Internet Archive between 2008-2015. The original intent of the project was to provide usage metrics to assist the Digitization Initiatives Committee in prioritizing projects or content areas. The project also uncovered trends that should impact how we think about making digital collections discoverable and accessible. For example, if 50-60% of traffic into UMD Digital Collections comes from outside the University or College Park, MD, how will this impact the potential usage of content when access is restricted to campus due to licensing, copyright, or ownership restrictions? With a growing population using mobile browsers, how will a flash-based viewer restrict users’ access to content? How might we develop content or its discoverability for a growing social media user base? In this talk, I will briefly discuss the usage trends for the represented collections, how we may use these in prioritizing future projects, and issues I will discuss with collection managers as we develop project plans and the Manager of Digital Programs and Initiatives as we develop the digital collections repository.

Managing Digitization Priorities with Metrics

This presentation was one of four during a Mid-Atlantic Regional Archives Conference presentation on April 15, 2016. Digitization of collections can help to improve internal workflows, make materials more accessible, and create new and engaging relationships with users. Laurie Gemmill Arp will discuss the LYRASIS Digitization Collaborative, created to assist institutions with their digitization needs, and how it has worked to help institutions increase connections with users. Robin Pike from the University of Maryland will discuss how they factor requests for access into selection for digitization and how they track the use of digitized materials. Laura Drake Davis of James Madison University will discuss the establishment of a formal digitization program, its impact on users, and the resulting increased use of their collections. Linda Tompkins-Baldwin will discuss Digital Maryland’s partnership with the Digital Public Library of America to provide access to archives held by institutions without a digitization program.

Custom Analytics with Google Tag Manager: Assessing Usage Statistics on the MD-SOAR Platform

As usage metrics continue to attain an increasingly central role in library system assessment and analysis, librarians tasked with system selection, implementation, and support are driven to identify metric approaches that simultaneously require less technical complexity and greater levels of data granularity. Such approaches allow systems librarians to present evidence-based claims of platform usage behaviors while reducing the resources necessary to collect such information, thereby representing a novel approach to real-time user analysis as well as dual benefit in active and preventative cost reduction. As part of the DSpace implementation for the MD SOAR initiative, the Consortial Library Application Support (CLAS) division has begun test implementation of the Google Tag Manager analytic system in an attempt to collect custom analytical dimensions to track author- and university-specific download behaviors. Building on the work of Conrad , CLAS seeks to demonstrate that the GTM approach to custom analytics provides both granular metadata-based usage statistics in an approach that will prove extensible for additional statistical gathering in the future. This poster will discuss the methodology used to develop these custom tag approaches, the benefits of using the GTM model, and the risks and benefits associated with further implementation.

Ottimizzazione di un Data Warehouse con Google Cloud Platform

I dati sono una risorsa di valore inestimabile per tutte le organizzazioni. Queste informazioni vanno da una parte gestite tramite i classici sistemi operazionali, dall’altra parte analizzate per ottenere approfondimenti che possano guidare le scelte di business. Uno degli strumenti fondamentali a supporto delle scelte di business è il data warehouse. Questo elaborato è il frutto di un percorso di tirocinio svolto con l'azienda Injenia S.r.l. Il focus del percorso era rivolto all'ottimizzazione di un data warehouse che l'azienda vende come modulo aggiuntivo di un software di nome Interacta. Questo data warehouse, Interacta Analytics, ha espresso nel tempo notevoli criticità architetturali e di performance. L’architettura attualmente usata per la creazione e la gestione dei dati all'interno di Interacta Analytics utilizza un approccio batch, pertanto, l’obiettivo cardine dello studio è quello di trovare soluzioni alternative batch che garantiscano un risparmio sia in termini economici che di tempo, esplorando anche la possibilità di una transizione ad un’architettura streaming. Gli strumenti da utilizzare in questa ricerca dovevano inoltre mantenersi in linea con le tecnologie utilizzate per Interacta, ossia i servizi della Google Cloud Platform. Dopo una breve dissertazione sul background teorico di questa area tematica, l'elaborato si concentra sul funzionamento del software principale e sulla struttura logica del modulo di analisi. Infine, si espone il lavoro sperimentale, innanzitutto proponendo un'analisi delle criticità principali del sistema as-is, dopodiché ipotizzando e valutando quattro ipotesi migliorative batch e due streaming. Queste, come viene espresso nelle conclusioni della ricerca, migliorano di molto le performance del sistema di analisi in termini di tempistiche di elaborazione, di costo totale e di semplicità dell'architettura, in particolare grazie all'utilizzo dei servizi serverless con container e FaaS della piattaforma cloud di Google.

Data analytics in the cloud with flexible mapreduced workflows

Data analytic applications are characterized by large data sets that are subject to a series of processing phases. Some of these phases are executed sequentially but others can be executed concurrently or in parallel on clusters, grids or clouds. The MapReduce programming model has been applied to process large data sets in cluster and cloud environments. For developing an application using MapReduce there is a need to install/configure/access specific frameworks such as Apache Hadoop or Elastic MapReduce in Amazon Cloud. It would be desirable to provide more flexibility in adjusting such configurations according to the application characteristics. Furthermore the composition of the multiple phases of a data analytic application requires the specification of all the phases and their orchestration. The original MapReduce model and environment lacks flexible support for such configuration and composition. Recognizing that scientific workflows have been successfully applied to modeling complex applications, this paper describes our experiments on implementing MapReduce as subworkflows in the AWARD framework (Autonomic Workflow Activities Reconfigurable and Dynamic). A text mining data analytic application is modeled as a complex workflow with multiple phases, where individual workflow nodes support MapReduce computations. As in typical MapReduce environments, the end user only needs to define the application algorithms for input data processing and for the map and reduce functions. In the paper we present experimental results when using the AWARD framework to execute MapReduce workflows deployed over multiple Amazon EC2 (Elastic Compute Cloud) instances.

Georeferencing Road Accidents with Google Earth: Transforming Information into Knowledge for Decision Support

Over the last fifty years mobility practices have changed dramatically, improving the way travel takes place, the time it takes but also on matters like road safety and prevention. High mortality caused by high accident levels has reached untenable levels. But the research into road mortality stayed limited to comparative statistical exercises which go no further than defining accident types. In terms of sharing information and mapping accidents, little progress has been mad, aside from the normal publication of figures, either through simplistic tables or web pages. With considerable technological advances on geographical information technologies, research and development stayed rather static with only a few good examples on dynamic mapping. The use of Global Positioning System (GPS) devices as normal equipments on automobile industry resulted in a more dynamic mobility patterns but also with higher degrees of uncertainty on road traffic. This paper describes a road accident georeferencing project for the Lisbon District involving fatalities and serious injuries during 2007. In the initial phase, individual information summaries were compiled giving information on accidents and its majour characteristics, collected by the security forces: the Public Safety Police Force (Polícia de Segurança Pública - PSP) and the National Guard (Guarda Nacional Republicana - GNR). The Google Earth platform was used to georeference the information in order to inform the public and the authorities of the accident locations, the nature of the location, and the causes and consequences of the accidents. This paper also gives future insights about augmented reality technologies, considered crucial to advances to road safety and prevention studies. At the end, this exercise could be considered a success because of numerous consequences, as for stakeholders who decide what to do but also for the public awareness to the problem of road mortality.

Innovations in technology: a friendly math project and the learning analytics “challenge”

Currently the world around us "reboots" every minute and “staying at the forefront” seems to be a very arduous task. The continuous and “speeded” progress of society requires, from all the actors, a dynamic and efficient attitude both in terms progress monitoring and moving adaptation. With regard to education, no matter how updated we are in relation to the contents, the didactic strategies and technological resources, we are inevitably compelled to adapt to new paradigms and rethink the traditional teaching methods. It is in this context that the contribution of e-learning platforms arises. Here teachers and students have at their disposal new ways to enhance the teaching and learning process, and these platforms are seen, at the present time, as significant virtual teaching and learning supporting environments. This paper presents a Project and attempts to illustrate the potential that new technologies present as a “backing” tool in different stages of teaching and learning at different levels and areas of knowledge, particularly in Mathematics. We intend to promote a constructive discussion moment, exposing our actual perception - that the use of the Learning Management System Moodle, by Higher Education teachers, as supplementary teaching-learning environment for virtual classroom sessions can contribute for greater efficiency and effectiveness of teaching practice and to improve student achievement. Regarding the Learning analytics experience we will present a few results obtained with some assessment Learning Analytics tools, where we profoundly felt that the assessment of students’ performance in online learning environments is a challenging and demanding task.
