Bot or not? a case study on bot recognition from web session logs
2018
This work reports on a study of web usage logs to verify whether it is possible to achieve good recognition rates in the task of distinguishing between human users and automated bots using computational intelligence techniques. Two problem statements are given, offline (for completed sessions) and on-line (for sequences of individual HTTP requests). The former is solved with several standard computational intelligence tools. For the second, a learning version of Wald’s sequential probability ratio test is used.
The Effects of the Use of Serious Game in Eco-Driving Training
2016
International audience; Serious games present a promising approach to training and learning. The player is engaged in a virtual environment for a purpose beyond pure entertainment, all while having fun. In this paper, we investigate the effects of the use of serious game in eco-driving training. An approach has been developed in order to improve players’ practical skills in terms of eco-driving. This approach is based on the development of a driving simulation based on a serious game, integrating a multisensorial guidance system with metaphors including visual messages (information on fuel consumption, ideal speed area, gearbox management, etc.) and sounds (spatialized sounds, voice message…
Assessment of Social Services’ Disaster Risk Management: Case Finland
2017
Local actors are crucial in disaster risk management; thus, their capacities should be assessed periodically. In this study, local social services’ preparedness plans were assessed using Emergency Management Program Measurement and quantitative document analysis. The specific aim was to study how social service areas of various sizes were prepared for disasters in Finland. The results showed that disaster risk management capacity varied significantly between large and small service areas. Larger areas were better prepared for supporting management, and had better procedures to activate their response, modern public information and deeper cooperation with the private sector and the civil soc…
The collaborative consistent vehicle routing problem with workload balance
2021
Abstract The rising competition in the logistics sector forces companies to be more economically efficient. One of the major sources of inefficiency is the incomplete usage of available resources, such as vehicles’ capacities. Mechanism that allow to better exploit such resources by enabling carrier collaborations are on the rise. Our study examines a centrally organized multi-period collaborative vehicle routing problem, where carriers can exchange customers who have to be serviced on a regular basis. Collaborations, where carriers serve frequent customers, are supposed to face the problem of (i) time consistency in terms of visiting time, and of (ii) service consistency. The latter ensure…
A privacy enhanced device access protocol for an IoT context
2013
In this paper, we present the case for a device authentication protocol that authenticates a device/service class rather than an individual device. The devices in question are providing services available to the public. The proposed protocol is an online protocol, and it uses a pseudo-random temporary identity scheme to provide user privacy. This allows the Internet-of-Things device to have full assurance of the user, with respect to the request service, while permitting the user to remain anonymous with respect to the device. The user can then enjoy identity and location privacy in addition to untraceability with respect to device access. Copyright © 2013 John Wiley & Sons, Ltd.
Value, supplier dependence and long‐term orientation
2011
PurposeIn organizational markets, many companies tend to reduce the number of providers to focus on establishing relationships with few of them. The purpose of this paper is to analyze the influence of relationship value and dependence of supplier on long‐term orientation and customer loyalty in the setting of relationships between travel agencies and their main providers.Design/methodology/approachA partial least square regression is performed to test a proposed model that links several relational variables with outcomes in terms of customer loyalty.FindingsResults provide support for the positive indirect influence of relationship value on long‐term orientation, while customer dependence …
Explaining non-adoption of electronic government services by citizens. A study among non-users of public e-services in Latvia
2018
This paper analyses citizen motives for not using electronic government services. Using qualitative interviews among users of Citizens´ Service Centers in Latvia, this paper analyses the motives of citizens not to use electronic government services but to rely on non-electronic equivalents or on in-person assistance. It expands the literature on e-commerce and e-government through an explicit focus on non-adoption rather than adoption. Findings show a higher than expected importance of hardware and internet availability, as well convenience factors as important reasons for non-adoption. The research furthermore reveals that the well-intentioned supply of non-electronic alternatives may hamp…
M-commerce - mobile commerce: a new frontier for E-business
2005
Mobile commerce involves the use of mobile computing devices in carrying out different types of economic transactions or enabling them to take place over space and time. The m-commerce includes use of such technologies as SMS services over a number of carriers (GSM, IS95, CDMA, W-CDMA), Bluetooth applications, and the integration of low-level digital carriers to IP based services through WAP or Compact HTML like the Japanese I-Mode service. This integration is one of the fastest growing markets of E-business and it will involve the development and design of a host of new applications, services, business models and technological solutions. The theme is both topical and challenging, as the nu…
Process reference frameworks as institutional arrangements for digital service innovation
2020
Abstract Information systems (IS) service organizations are increasingly more concerned with their ability to co-create digital services with customers in service ecosystems. Practitioners and researchers, however, lack understanding of which organization mechanisms effectively contribute to IS organizations’ innovation practices. Grounded in service-dominant logic, we hypothesized that process reference frameworks (PRFs), such as the IT Infrastructure Library (ITIL), act as institutional arrangements through their norms, rules, and practices, enhancing IS organizations’ ability to innovate digital services. Data collected from 159 IS organizations confirmed our hypotheses, showing that eff…
Consumer Information Systems as Services
2017
Consumer Information Systems (CIS) are a type of information systems that provides services to consumers instead of addressing users in traditional organizational settings, such as Internet based television. Services typically involve a trade-off between achieving high service productivity and quality. The use of service mass customization to successfully address these issues of both productivity and quality in a service context is proposed. We suggest that the development of Consumer Information Systems as Services (CISaS) may achieve such service mass customization. This paper presents a conceptual framework and investigates how it applies to a set of Internet Protocol Television (IPTV) o…
