Usability Assessment of a Context-Aware and Personality-Based Mobile Recommen...Matthias Braunhofer
In this paper we present STS (South Tyrol Suggests), a context-aware mobile recommender system for places of interest (POIs) that integrates some innovative components, including: a personality questionnaire, i.e., a brief and entertaining questionnaire used by the system to learn users’ personality; an active learning module that acquires ratings-in-context for POIs that users are likely to have experienced; and a matrix factorization based recommendation module that leverages the personality information and several contextual factors in order to generate more relevant recommendations.
Adopting a system oriented perspective, we describe the assessment of the combination of the implemented components. We focus on usability aspects and report the end-user assessment of STS. It was obtained from a controlled live user study as well as from the log data produced by a larger sample of users that have freely downloaded and tried STS through Google Play Store. The result of the assessment showed that the overall usability of the system falls between “good” and “excellent”, it helped us to identify potential problems and it provided valuable indications for future system improvement.

Similar to Part 1: Website quality evaluation 7Loci method (20)
Creativity and creativity techniques are relevant for requirements elicitation. There are many different creativity techniques, but these techniques are not used as widely as expected. To investigate the reasons for this situation, we assumed the viewpoint of a requirements engineer looking for decision-making guidelines to facilitate the choice among the considerable number of available creativity techniques. The results of the search highlighted the gap between existing information and what is needed. To this end, we propose a logical framework based on two matrices for choosing creativity techniques and methods in view of their application in requirements elicitation.

The second monitoring exercise, that addressed students who obtained the ECDL (European Computer Driving License) certification during their high schools, was aimed at investigating their point of view with respect to their certification experience.
Accountability of Artificial IntelligenceLuisa Mich
Recent advances in artificial intelligence raise a number of concerns. Among the challenges to be addressed by researchers, accountability of artificial intelligence solutions is one of the most critical. This paper focuses on artificial intelligence applications using natural language to investigate if the core semantics defined for a large-scale natural language processing system could assist in addressing accountability issues. Core semantics aims to obtain a full interpretation of the content of natural language texts, representing both implicit and explicit knowledge, using only ‘subj-action-(obj)’ structures and causal, temporal, spatial and personal-world links. The first part of the paper offers a summary of the difficulties to be addressed and of the reasons why representing the meaning of a natural language text is relevant for artificial intelligence accountability. In the second part, a-proof-of-concept for the application of such a knowledge representation to support accountability, and a detailed example of the analysis obtained with a prototype system named CoreSystem is illustrated. While only preliminary, these results give some new insights and indicate that the provided knowledge representation can be used to support accountability, looking inside the box.
The document discusses artificial intelligence (AI) and its applications for customer experience (CX). It provides an overview of different AI technologies and categorizes them using the AI Knowledge Map. This map classifies AI technologies according to their paradigm (symbolic, statistical, subsymbolic) and problem domain (reasoning, knowledge, etc.). The document recommends using this map to identify suitable AI technologies based on the type of input needed and problem to be solved. It also notes challenges for AI adoption such as trust, security, privacy and the need for explainability.
Designing usable websites becomes a subject of major importance with the growth of e-commerce applications and the wide range of offers the web suggests. To reach potential customers and maintain their loyalty under the conditions of high competition, organizations need to constantly control usability of the websites representing them. In this paper we present a systematic approach to usability, based on a roadmap, that aims to overcome quality gaps appearing in website lifecycle. To address these gaps it is possible to adopt different techniques. Our solution consists in identifying the quality gaps and suggesting the techniques most adequate to overcome a given gap. The result is a multi-step process for determining and realizing the improvements and re-engineering of the website. We illustrate our approach on the website of a tourist destination.
Artificial intelligence (AI) is fascinating a discipline and research field. It dates back to the beginning of the second half of the last century and was developed with a view to creating intelligent agents mimicking human intelligence. The initial enthusiasm soon partially faded, given the under-evaluated difficulties in dealing with intelligent behaviours and tasks. The complexity of the problems at hand have suggested different approaches, related to two complementary visions, namely the weak and the strong AIs, which both provided insights into the nature of the intelligence and the design and implementation of intelligent systems. In recent years, results in the many sub fields of artificial intelligence have taken to a widespread availability and dissemination of intelligent technologies. In this context, a preliminary analysis of the AI applications for the tourism sector is proposed.
This document summarizes a study on the mobile web strategies of 13 major Italian opera houses. The study analyzed the mobile-friendliness and usability of the opera houses' websites, as well as their e-commerce models for ticket sales. It found that only 10 of the 13 websites were mobile-friendly, and many had usability issues when viewed on mobile. Most opera houses outsourced their ticket sales to third-party platforms. The study concluded the opera houses have not fully embraced mobile strategies and its findings could help them improve their mobile web presence to better promote opera as a cultural tourism attraction.

Conceptual modelling from natural languageLuisa Mich
The document describes the NL-OOPS project, which aims to build a natural language processing (NLP)-based computer-aided software engineering (CASE) tool to support requirements analysis. The tool uses the NLP system LOLITA to identify objects and associations from natural language requirements texts in order to perform object-oriented analysis. It presents an algorithm for this object identification process that first filters irrelevant information before analyzing events to determine classes, associations, and operations. An example case study of analyzing hotel reservation system requirements is also provided.
1. The document presents a model called 2QCV3Q for managing the quality of a website. 2QCV3Q evaluates a website across seven dimensions: identity, content, services, location, maintenance, usability, and feasibility.
2. The model was used to design websites for several organizations, including a non-profit focused on reducing children's pain called No Pain for Children. Requirements for the No Pain for Children site were identified using interviews, meetings, and analyzing competitor sites.
3. The 2QCV3Q model facilitates communication between stakeholders, helps identify potential conflicts, and allows for synthesizing gathered information across the seven evaluative dimensions. The model conceptualizes quality as dynamic and iterative
Tourist destination players information requirements enter 2001Luisa Mich
The project to apply ICT to support the decision making process of players in a tourist destination presupposes knowledge of the existing relationships and exchanges of information among them. Analysis of information flows must be based on a representation of the complexity of the co-ordination problem, because corresponding to different levels of complexity are different applications of ICT. To this end, the paper presents a method for classifying the relationships among the players of a tourist destination. This method moves through three main phases: identification of the players involved in the development process in the destination, analysis of existing communication flow among the main players (context diagrams construction). definition of the potential application of ICT in support to the co.ordination.

This presentation provides a model to classify and analyze the different forms of presence on the Web for a company or an organization. In fact, beside the official websites, there are a variety of new ‘spaces’ related to the so called Web 2.0 which can be included by managers in the company’s strategy for a comprehensive Web presence. The suggested model is meant to analyze the characteristics of the different forms of Web presence and support an organization or company in decision-making about their adoption. The Web 2.0 presence model and its application are illustrated for a set of tourism destination management organizations of the European countries. Interesting results emerge from the study, both in terms of existing Web presence strategies and in terms of guidelines and recommendations for improving Web presence in general.
Paradosso degli investimenti informaticiLuisa Mich
Esiste un paradosso per gli investimenti in tecnologie informatiche e più in generale in sistemi informativi? Quali sono i ritorni degli investimenti? Si possono valutare? Una presentazione del 2004 ma con spunti attualissimi.
HijackLoader Evolution: Interactive Process HollowingDonato Onofri
CrowdStrike researchers have identified a HijackLoader (aka IDAT Loader) sample that employs sophisticated evasion techniques to enhance the complexity of the threat. HijackLoader, an increasingly popular tool among adversaries for deploying additional payloads and tooling, continues to evolve as its developers experiment and enhance its capabilities.
In their analysis of a recent HijackLoader sample, CrowdStrike researchers discovered new techniques designed to increase the defense evasion capabilities of the loader. The malware developer used a standard process hollowing technique coupled with an additional trigger that was activated by the parent process writing to a pipe. This new approach, called "Interactive Process Hollowing", has the potential to make defense evasion stealthier.

Given the high level of competition existing
on the Web, simply being present on-line
does not guarantee that a site’s sponsors
will reach their objectives for and through
the site. Not only, but often the creation of

and homogeneous manner
50. The 7Loci as meta-model:
validation (cont’d)
The 7Loci meta-model provides a common
conceptual framework that supports the evaluator in
finding the right weight quality model, doing so by
taking into account the goals of the project:
it is possible to adopt a relatively standard model
built around the dimensions of 7Loci – largely

domain independent – to identify high performing
sites and to rank them
if the aim is to identify weaknesses in the site
and plan its eventual re-design, the 7Loci
dimensions can be used to define more detailed
models based on user needs, owner’s goals, etc.
