A Cognitive-based scheme for user reliability and expertise assessment in Q&A social networks
2011
Q&A social media has gained a great deal of attention during recent years. People rely on these sites to obtain information due to the number of advantages they offer as compared to conventional sources of knowledge (e.g., asynchronous and convenient access). However, for the same question one may find highly contradictory answers, causing ambiguity with respect to the correct information. This can be attributed to the presence of unreliable and/or non-expert users. In this work, we propose a novel approach for estimating the reliability and expertise of a user based on human cognitive traits. Every user can individually estimate these values based on local pairwise interactions. We examine…
Similarity and Consistency in Hotel Online Ratings across Platforms
2019
Online ratings are a major driver of hotel choice. There are many ratings platforms, and the number of evaluations is huge. This article analyzes if hotel ratings vary across platforms, vary over time, and if consistency in ratings can be observed. Longitudinal online ratings taken from 11 platforms over a two-year period were analyzed through Self-Organizing Maps. The findings suggest a similar pattern of online ratings across most of the platforms, except for Yelp and HolidayCheck. In addition, the evaluation patterns are stable over time, and the analyzed attributes do not contribute decisively to explain the overall evaluation of hotels, which implies that tourists use a noncompensator…
Memorable tourist experiences versus ordinary tourist experiences analysed through user-generated content
2020
Abstract This study aims to test some previously proposed MTE (memorable tourist experience) scales by using UGC (user-generated content) posted in social media sites, through script theory and thematic analysis. In addition, MTEs and OTEs (ordinary tourist experiences) are compared to identify any significant differences between their dimensions. The results suggest that some dimensions of the MTE scale (hedonism, novelty, meaningfulness, involvement, knowledge and serendipity) are significantly more frequently reported in MTEs than in OTEs, but are not exclusive to MTEs. Despite this, the MTE scale dimensions are able with some accuracy to classify tourist experiences as MTEs or OTEs. Thu…
Through a Glass, Darkly
2013
Political actors increasingly use the microblogging service, Twitter, for the organization, coordination, and documentation of collective action. These interactions with Twitter leave digital artifacts that can be analyzed. In this article, we look at Twitter messages commenting on one of the most contentious protests in Germany’s recent history, the protests against the infrastructure project Stuttgart 21. We analyze all messages containing the hashtag #s21 that were posted between May 25, 2010, and November 14, 2010, by the 80,000 most followed Twitter users in Germany. We do this to answer three questions: First, what distinguishes events that resulted in high activity on Twitter from ev…
Evolving e-government benchmarking to better cover technology development and emerging societal needs
2012
Many international e-government benchmarks seek to measure progress towards various versions of a digital society, and in this endeavor include a component of e-government. But because comparable international e-government data are scarce, most reports rely on the United Nations E-Government Development Index, specifically its Online Service Index as a benchmark. However, this assessment only captures national level initiatives at a broad level and does not link evaluation to outcomes and impacts, i.e. e-government performance relative to investment.This paper briefly reviews the current UN framework and assesses how it can evolve to meet new demands, such as calls to better connect investm…
Employee-driven digitalization in healthcare: codesigning services that deliver
2020
Abstract The purpose of this article is to explore and conceptualize how Nordic principles of employee participation combined with enterprise social media/web 2.0 could enable co-creation as an input to digital transformation of healthcare services. The question of how to enable effective co-creation is both under-researched and stated as an important enabler of digitalization and service improvements. The article starts by introducing The Nordic Model for employee participation that is proven successful for enhancing working life effectiveness and innovation. We then discuss how these principles of participation can be further enhanced by state-of-the-art web 2.0 technologies for Enterpris…
Co-designing a social media service for civic participation
2010
User participation in social media design processes has similarities with civic participation for example in urban planning. Internet enables new virtual environments that can be planned collaboratively and be used for civic participation. In the Monimos case study we developed a social media website for immigrants and multicultural associations in a participatory design process together with the users. In this paper we present the critical issues in co-designing a social media service that aims at civic participation. We also give suggestions for how to cope with the challenges in a multicultural participation process. We claim that constant meta-level discussion about the goals and partic…
Social Media and Crowd Diagnosis
2022
The chapter aims at exploring social media platforms as used by individuals to obtain (first or second) opinions in the form of crowd-diagnosis (Nobles et al. 2019) within a social media-critical discourse study (SM-CDS, KhosranoviNik 2018a) perspective. This study explores the communicative ‘territory’ of medical history presentation and, more particularly, it reports results on the communicative skills used by online users to present their own history and design it as challenging. To this end, this work adopts a critical discourse-based perspective on the language used for history-giving. I shall focus on the communicative resources which are employed by patients to be ‘visible’ at the in…
In facebook we trust? Social media and political engagement, between Italian and Tunisian youth
2020
The article shows the results of a qualitative research on the use of social media by Tunisian and Italian youth, which is part of a broader project on Mediterranean digital culture. More precisely, this work is based on a series of focus groups, and aims at analyzing political participation, engagement and citizen journalism, by focusing on two countries deeply affected by digital propaganda – in Italy, with the growing popularity of Five Star Movement among young people, and in Tunisia with all aftermaths of the Arab Spring. Twelve focus groups were realized, with a total of 96 interviewed. As a result, we will consider two main findings: a critical use of social media, on the one hand, a…
Social media, percorsi e narrazioni: una geografia digitale del turismo naturalistico
2023
Il turismo, soprattutto quello di massa, può avere un impatto negativo sull’ambiente e sulle culture locali. Al fine di superare questa criticità negli ultimi anni si sono moltiplicate le proposte di forme di turismo alternativo. Tra queste il turismo naturalistico offre delle interessanti opportunità, oggi accentuate dalla diffusione dei social media e da piattaforme digitali realizzate per aiutare e incentivare gli utenti propensi ad esplorare gli ambienti naturali. In questo lavoro, oltre a descrivere le più comuni dinamiche e criticità riguardanti il turismo naturalistico, si approfondisce il caso della piattaforma digitale AllTrails. Social media, routes and narrations: a digital geogr…
