    This study aims to identify user segmentations of a learning management system at Universitas Negeri Malang using two-step clustering method. Data is collected through an on-line survey which is linked onto the academic information systems. Total number of data are 10.594 responses. This study runs three clustering methods, two-step, k-means, and kohonen clustering, in order to identify the user segmentation. Two-step clustering methods performs better than the other two clustering methods (k-means and kohonen) based on silhouette clustering index. The number of cluster resulted from two-step clustering method are three clusters. The top three of most important factors in identifying the user segmentation are the benefit of the learning management usage in helping to access information, increasing the effectiveness of accomplishing assignments, and students satisfaction on the learning management system services

    Este trabalho foi desenvolvido no Ć¢mbito do Mestrado em Engenharia InformĆ”tica e consiste na dissertaĆ§Ć£o escrita para a obtenĆ§Ć£o do respectivo grau.Na origem e motivaĆ§Ć£o deste trabalho esteve um hiato no conhecimento, que consistia em saber se se poderia usar indicadores de eficiĆŖncia como instrumento para a monitorizaĆ§Ć£o e gestĆ£o de processos inerentes aos ServiƧos de DocumentaĆ§Ć£o e InformaĆ§Ć£o, num contexto de optimizaĆ§Ć£o de processos e de prestaĆ§Ć£o de contas aos stakeholders.Nesse sentido, comeƧou-se este trabalho por fazer uma revisĆ£o da literatura acerca de abordagens existentes para a avaliaĆ§Ć£o dos ServiƧos de DocumentaĆ§Ć£o e InformaĆ§Ć£o e dos processos que lhes sĆ£o inerentes, tendo sido estudadas 4 abordagens: valorizaĆ§Ć£o contingente, Balenced ScoreCards, indicadores e impactos.Seguidamente, foi feita a opĆ§Ć£o por uma das abordagens de avaliaĆ§Ć£o estudadas. Nessa opĆ§Ć£o, foi tido em consideraĆ§Ć£o que no caso de estudo que se utilizou neste trabalho - o ServiƧo de DocumentaĆ§Ć£o e InformaĆ§Ć£o da Faculdade de Engenharia da Universidade do Porto - jĆ” Ć© corrente a utilizaĆ§Ć£o de indicadores para avaliar o ServiƧo. Assim, optou-se por aprofundar a abordagem dos indicadores mas, ao nĆ­vel dos processos.Posteriormente, apĆ³s a anĆ”lise e modelaĆ§Ć£o do processo principal do ServiƧo - processo "Gerir documento" - identificou-se 6 indicadores de eficiĆŖncia (3 de custo e 3 temporais) e, de acordo com a norma NP ISO 11620: 2004, desenvolveu-se a respectiva grelha descritiva, de modo a que estes possam ser usados por outros ServiƧos e atĆ© serem incluĆ­dos na norma numa fase posterior.Finalmente, foi feito um caderno de requisitos de um sistema que permitirĆ” calcular os indicadores identificados, que consistiu no levantamento de requisitos e na respectiva modelizaĆ§Ć£o em UML.Palavras-chave:- Indicadores de eficiĆŖncia;- Processos;- ServiƧos de DocumentaĆ§Ć£o e InformaĆ§Ć£o.This work was developed under the Informatics Engineering Master programme and is the written dissertation to obtain the respective degree.In the origin and motivation of this work was a hiatus in knowledge, which consisted in knowing whether it could be used efficiency indicators as a tool for monitorization and management of processes inherent to Library and Information Services, in a context of processes optimization and stakeholders rendering of accounts.In this orientation, this work had begun by doing a literature review on existing approaches for the evaluation of Library and Information Services and of its inherent processes. In that review 4 approaches were studied: contingent valuation, Balenced ScoreCards, indicators and outcomes.Then, a choice was made by one of the studied approaches. In that choice, has been taken into consideration that in the case study that was used in this work - the Library and Information Service of the Faculty of Engineering of the University of Porto - is common to use indicators to evaluate the Service. So, we decided to deepen the indicators approach but on the level of processes.Posteriorly, after the analysis and modeling of the main Service process, which name is "Gerir documento", 6 efficiency indicators were identified (3 of cost and 3 of time). Then, in concordance to the standard NP ISO 11620: 2004, was developed its descriptive framework, so that they can be used by other Services and eventually to be included in the standard.Finally, was developed a set of requisites for a system that will be able to calculate the identified indicators, which consisted in requisites gathering and the respective UML model.Keywords:- Efficiency indicators;- Processes;- Library and Information Services
