A Review of Lean-Kanban Approaches in the Software Development
No full textWe present a review on the state-of-the-art of the adoption of a specific Agile Methodology (AM), the Lean-Kanban, in different software development contexts. Such approach requires to break down the software development process into smaller steps, which are implemented with the aid of a Kanban board. We study 14 different Kanban boards and we also examined how features are represented in the boards and compared 22 software tools for implementing virtual Kanban boards, analyzing also resources available on the web. We analyzed the main features of the Kanban boards actually used, the main activities defining the software development process, the content of the cards representing work units, and also the automation tools available for Kanban board management. Our survey shows that nor standard definitions of Kanban practices exist for the software development, neither specific practices for the Kanban board management have been rigorously defined, and thus Lean development standardization and improvement is still an unaccomplished task for software development
An Approach to Multimedia Content Management
No full textStandardized formalizations of the knowledge are used by domain experts to share information in the form
of reusable knowledge. The primary objective of our work is the definition of an approach for multimedia
content management. We reached that goal through a validation activity which lasted for the last three
years, and was carried on through the application on different case studies, some of them described in detail
in previously published papers. This approach aims to represent the knowledge through a mixed-iterative
approach, where top-down and bottom-up analyses are applied on the knowledge domain we want to
represent. We focused our research on some issues concerning Knowledge Management, strictly related to
the process of making multimedia content-related knowledge easily available to users. We need to represent
and manage this knowledge, in order to formalize and codify all the knowledge in the domain. This
formalization can eventually lead us to easily manage that knowledge through the use of repositories
Using a standards-based approach for a multimedia knowledge-base
No full textIn recent years, we witnessed the diffusion and rise in popularity of software platforms for User Generated
Content management, especially multimedia objects. These platforms handle a big quantity of unclassified
information. UGC sites (i.e. YouTube and Flickr) do not force the users to perform classification operations
and metadata definitions, leaving space to a logic of free-tags (Folksonomies). In the context of an industrial
project financed by the Autonomous Region of Sardinia, the idea of producing a Geolocalized Guide based
on a Knowledge-base came forth. Such Guide would be able to share georeferenced content with their users,
originated from UGC sources as well as from users themselves. For this purpose, we defined an ontology
that can represent the semantics of multimedia content, especially its metadata, which in turn can be given
an unambiguous meaning. The innovation in this work is represented by the use of the Adobe XMP,
DUBLIN CORE, EXIF, IPTC standards as a starting point. In order to unify metadata coming from
different sources we defined all laws of mapping toward a structure defined by sources like YouTube and
Flickr
The FAME Tool: An Automated Supporting Tool for Assessing Methodology
No full textThe FAMEtool is a support tool for the FAME (Filter, Analyze, Measure and Evaluate) Methodology, an iterative approach for open source software assessment. The FAMEtool does not replace evaluation experts, but it serves to improve the productivity of experts in evaluating the different solutions. The efficacy of the FAMEtool is reported in this paper. Several methods have been created to define a process for assessing Free/Open Source software. Some focus on some aspects like the maturity, the durability and the strategy of the organization around the Open Source project itself. Other methodologies add functional aspects to the assessment process. Only some of these methodologies are supported by specific tools. This paper describes the FAMEtool that implements the steps of the FAME methodology, particularly in the filtering and analysis phases, trying to follow the logic of the simplified method that allows a faster application and gives support to who will be engaged in the selection of the new IT solution. Such a tool is introduced in the form of Web application and has been developed in Java
A New Approach for Knowledge Management and Optimization using an Open Source Repository
No full textThe Institutional Repositories (Irs) based on Open Archives represent one of the main free access tools for the results of scientific research, and their diffusion is continuously growing. In the context of the “Analytic Sound Archive of Sardinia” project, that aims to create an institutional archive with a linguistically annotated electronic corpus, this work proposes a new approach for management of knowledge using the tool Dspace (an open source software package developed in 2000 in the context of a joint project of the Massachusetts Institute of Technology with Hewlett-Packard): the purpose is to offer an original way to associate linguistic annotations (information associated to specific text portions) to the corpus by treating them as metadata, so as to insert and manage them in the archive of choice after formalizing them in XML. The formalization level of this approach allows for effective text retrievals through a metadata schema and easy, quick corpus interrogations, by formalizing linguistic annotation as a structured metadata schema. There is, thus, the need to have an efficient tool that could classify and store the vast amount of knowledge contained in an electronic corpus of spoken texts of Sardinian language, linguistically annotated at various levels, and that could allow a high usability in terms of ease of reference as well as ease of query and communication
Content Management in Digital Libraries
No full textIn recent years, the development of models to
formalize knowledge has been studied and analysed. Many
disciplines develop standardized formalization of knowledge,
which domain experts can use to share information in the
form of reusable knowledge. The purpose of this paper is to
formalize knowledge through a mixed-iterative approach,
applying a top-down and bottom-up analysis of the knowledge
domain to represent. Our study is part of an industrial project
being funded by the Autonomous Region of Sardinia, with the
goal of implementing a web-based application with innovative
functionalities in the field of semantic search and digital
content management. We consider the case of Italian
libraries, which have moved from holding mainly printed
resources to a collection that includes also multimedia
objects, such as music, databases, ebooks, audio sources, and
websites, over the last decade
