User-Centred Methods for Measuring the Value of Open Data

A project to identify metrics for assessing the quality of open data based on the needs of small voluntary sector organisations in the UK and India. For this project we assumed the purpose of open data metrics is to determine the value of a group of open datasets to a defined community of users. We adopted a much more user-centred approach than most open data research using small structured workshops to identify users’ key problems and then working from those problems to understand how open data can help address them and the key attributes of the data if it is to be successful. We then piloted different metrics that might be used to measure the presence of those attributes. The result was six metrics that we assessed for validity, reliability, discrimination, transferability and comparability. This user-centred approach to open data research highlighted some fundamental issues with expanding the use of open data from its enthusiast base.

Big data and open data as sustainability tools: A working paper prepared by the Economic Commission for Latin America and the Caribbean

The two main forces affecting economic development are the ongoing technological revolution and the challenge of sustainability. Technological change is altering patterns of production, consumption and behaviour in societies; at the same time, it is becoming increasingly difficult to ensure the sustainability of these new patterns because of the constraints resulting from the negative externalities generated by economic growth and, in many cases, by technical progress itself. Reorienting innovation towards reducing or, if possible, reversing the effects of these externalities could create the conditions for synergies between the two processes. Views on the subject vary widely: while some maintain that these synergies can easily be created if growth follows an environmentally friendly model, summarized in the concept of green growth, others argue that production and consumption patterns are changing too slowly and that any technological fix will come too late. These considerations apply to hard technologies, essentially those used in production. The present document explores the opportunities being opened up by new ones, basically information and communication technologies, in terms of increasing the effectiveness (outcomes) and efficiency (relative costs) of soft technologies that can improve the way environmental issues are handled in business management and in public policy formulation and implementation.

Information access law and disclosing of information by joint-stock companies in Brazil: open data and Extensible Business Reporting Language (XBRL) standard

The strategic management of information plays a fundamental role in the organizational management process since the decision-making process depend on the need for survival in a highly competitive market. Companies are constantly concerned about information transparency and good practices of corporate governance (CG) which, in turn, directs relations between the controlling power of the company and investors. In this context, this article presents the relationship between the disclosing of information of joint-stock companies by means of using XBRL, the open data model adopted by the Brazilian government, a model that boosted the publication of Information Access Law (Lei de Acesso à Informação), nº 12,527 of 18 November 2011. Information access should be permeated by a mediation policy in order to subsidize the knowledge construction and decision-making of investors. The XBRL is the main model for the publishing of financial information. The use of XBRL by means of new semantic standard created for Linked Data, strengthens the information dissemination, as well as creates analysis mechanisms and cross-referencing of data with different open databases available on the Internet, providing added value to the data/information accessed by civil society.

La descrizione di un'applicazione sviluppata per la visualizzazione di shapefile in google map e openstreetmap

Generazione automatica di visualizzazioni di open data quantitativi

Le sfide dell'Information Visualisation ed i limiti dei sistemi di visualizzazione esistenti hanno portato alla creazione di un nuovo sistema per la generazione automatica di visualizzazioni di Open Data quantitativi, presentato in questa tesi.

Open Data: alcune esperienze significative

La tesi si propone di mettere in evidenza alcuni esempi pratici di utilizzo degli Open Data sia in ambito delle pubbliche amministrazioni sia in quello più ampio della sensibilità ambientale, con esempi anche di utilizzi particolarmente interessanti.

Analisi comparativa di software per la pubblicazione di open data

Lo scopo di questa tesi è quella di analizzare in dettaglio i principali software usati a livello mondiale per la pubblicazione degli open data, per fornire una guida a sviluppatori che non conoscono i programmi adatti a questa fase. La prima parte della tesi sarà concentrata ad introdurre il mondo degli open data, con definizioni, concetti e leggi sull’argomento. La seconda parte sarà invece il fulcro dell’analisi tra diversi software già largamente utilizzati per pubblicare open data.
