Assisted labeling for spam account detection on twitter

2019

Online Social Networks (OSNs) have become increasingly popular both because of their ease of use and their availability through almost any smart device. Unfortunately, these characteristics make OSNs also target of users interested in performing malicious activities, such as spreading malware and performing phishing attacks. In this paper we address the problem of spam detection on Twitter providing a novel method to support the creation of large-scale annotated datasets. More specifically, URL inspection and tweet clustering are performed in order to detect some common behaviors of spammers and legitimate users. Finally, the manual annotation effort is further reduced by grouping similar u…

The role of social networking services in eParticipation

2009

Published version of a chapter published in Lecture Notes in Computer Science, 5694, 46-55. Also available from the publisher at: http://dx.doi.org/10.1007/978-3-642-03781-8_5 A serious problem in eParticipation projects is citizen engagement – citizens do not necessarily become more willing to participate simply because net-services are provided for them. Most forms of eParticipation in democratic contexts are, however, dependent on citizen engagement, interaction and social networking because democratic systems favour the interests of larger groups of citizens – the more voices behind a political proposition, the greater its chances of success. In this context of challenges the study of s…

A privacy-aware framework for decentralized online social networks

2015

Online social networks based on a single service provider suffer several drawbacks, first of all the privacy issues arising from the delegation of user data to a single entity. Distributed online social networks (DOSN) have been recently proposed as an alternative solution allowing users to keep control of their private data. However, the lack of a centralized entity introduces new problems, like the need of defining proper privacy policies for data access and of guaranteeing the availability of user's data when the user disconnects from the social network. This paper introduces a privacy-aware support for DOSN enabling users to define a set of privacy policies which describe who is entitle…

Towards a fuzzy-linguistic based social network sentiment-expression system

2015

Liking allows users of Social Networks, blogs and online magazines to express their support of posts and artifacts by a simple click. Such function is very popular but lacks semantic power, and some platforms have augmented it by allowing to choose a pictographic depiction corresponding to a feeling. What is gained in depth is lost in simplicity, and the wide acceptance liking has enjoyed did not carried to the sentiment version. We outline a sentiment-expression hybrid system based on textual analysis and linguistic fuzzy Markov chains overcoming the intrinsic limitations of liking without burdening the user with complex choices.

Towards Understanding of Software Engineer Motivation in Globally Distributed Projects

2011

Motivation in software engineering is reported to be a source for performance improvement, which leads to project overall success. Since it is a soft factor and difficult to quantify it is usually neglected. Research in this field is rather scarce and outdated. On the basis of a recent systematic review of software engineers' motivation we set an agenda for further investigation of the role of motivation in contemporary projects. As software organizations nowadays seek opportunities inherited in both - global software development (GSD) and agile projects, it is important to understand how different project environments influence motivation.

Best Practices for International eSourcing of Software Products and Services

2008

This paper analyzes how the information and communications technology-supported international eSourcing of software products and services (IeS) can be effectively executed. The extant literature falls short of providing a systematic and detailed enough set of best practices to guide IeS. This paper presents best practices for IeS to facilitate further research, and to help managers and other stakeholders to understand, execute, and proactively improve and manage international eSourcing. The practices emphasize the need to establish and enact rigorous, mature, and quantitatively managed eSourcing life- cycles in order to transcend temporal, geographical, social, technical, and other boundari…

Analysing software integration scenarios: the case of telecommunications operations software

2008

Telecom operators deploy a vast number of software systems to support their operations. Vendors of this software often integrate in their products several software systems, in order to enable innovations, minimize customer's integration efforts, etc. Different integration scenarios can be envisioned, and the issue of identifying more beneficial scenarios is of a great importance to the vendors. This paper aims at analyzing different software integration scenarios from the viewpoint of their support for innovations, and focuses on the context of telecommunications operations software. For each scenario, the overall modularity of the set of software systems is evaluated, and the expected bene…

Apathy Towards the Integration of Usability Work: A Case of System Justification

2016

In this article we report from a case study of a software development organization and we study in particular the developers’ and product managers’ attitudes towards integrating usability work into software development. We offer explanations based on system justification theory illuminating what would-be integrators might be up against. The analysis shows how the developers only pay lip service to usability work and how they treat users superficially. It further shows how that leads to stereotyping of usability designers and users in order to preserve status quo, and how internalization of inequality between the developers and usability designers rationalizes the preservation of status quo.…

Explaining Change Paths of Systems and Software Development Practices

2010

This chapter discusses how systems development practices are shaped. Based on interviews conducted in ten development organizations and previous literature, we identify eight types of change paths in systems development practices: emergence, adoption, idealization, formalization, abandonment, informalization, entropy, and disobedience. We argue that the eight change path types provide an integrated theoretical framework on the study of how systems development practices change in organizations, projects, and among individual developers in a given context. We discuss how this framework complements existing theories and concepts of the contemporary literature on systems development.
