Best practices provide convenient, but general, guidelines for authoring web content; however, as general guidelines, they cannot possibly provide the best advice for every context. Testing is required to know if their application works in a specific context. However, testing web content is challenging, especially content that does not support the funnel-shaped interactions typically found in commerce-oriented...
In the service oriented, customer experience centric and customer changing demand driven market environment, ICT is becoming the leading enabler and partner of the modern enterprise business. More and more companies are transformed into more or pure digital style and virtual organized enterprises that are enabled and supported by a group of business oriented and microservice based applications and...
Archaeology is a broad church and its role as a “two culture” discipline is frequently cited. This position at the interface of the arts and sciences remains central to archaeological activity but there have been significant changes in the structure of archaeology and its relationship to society overall. The growth of heritage science, in particular, is driving change and development within archaeology...
The society is in a state where learning has no limits and starts to overlap with technological developments. The recent advent of a connectivistic learning theory promises to shed light on how we learn in environments of interconnected knowledge and how the connectivity of concepts can guide the learning and conceptualization. This paper will have a look at a domain ontology-based approach to learning...
Emergency command and control centers (CC) are integrated facilities to assist and handle crisis situations. In these CCs, operators suffer both with information shortage and overload. This paper focuses on the information overload problem. Operators often do not have adequate access to information that may be relevant in the decision-making process. In many CC centers, information is stored without...
Passive brain-computer interfacing allows computer systems direct access to aspects of their user's cognition. In essence, a computer system can gain information about its user without this user needing to explicitly communicate it. Based on this information, human-computer interaction can be made more symmetrical, solving an age-old but still fundamental problem of present-day interaction techniques...
Typically, news articles mention not just one but multiple events. These events can be classified into subject or background events. The former are events that the article is written about, while the latter are additional events referred to in order to explain the background of the subject events (e.g., causal relations, circumstances or the consequences of the main event). Background events are considered...
This paper presents a new representation for handwritten math formulae: a Line-of-Sight (LOS) graph over handwritten strokes, computed using stroke convex hulls. Experimental results using the CROHME 2012 and 2014 datasets show that LOS graphs capture the visual structure of handwritten formulae better than commonly used graphs such as Time-series, Minimum Spanning Trees, and k-Nearest Neighbor graphs...
Utilizing a language model in a brain-computer-interface-based (BCI-based) speller has been proven helpful in improving the performance of the system. Since it is important to evaluate the effect of the language model on the system, it is necessary to choose the words in a way that they can represent different levels of difficulty based on the language model. In this paper, we will give a brief introduction...
Agent-based modeling is a paradigm of modeling dynamic systems of interacting agents that are individually governed by specified behavioral rules. Training a model of such agents to produce an emergent behavior by specification of the emergent (as opposed to agent) behavior is easier from a demonstration perspective. While many approaches involve manual behavior specification via code or reliance...
In this paper, we present an event handling framework for managing smart-grids and renewable energy installations: SmartSpace. Our framework aims at supporting decisions of human stakeholders, by providing adequate information to them. Different datasources feed into our framework and a variety of analysis and decision steps are supported. We are discussing potential data sources for decisions around...
The main focus of research in algorithm visualization has lately been on pedagogical aspects, but graphical features also deserve be studied. This paper presents an evaluation conducted with students on the convenience of including several graphical elements (labels for identifiers, arrows and shadows) in the visualization of an iterative algorithm. Students performed two tasks: to answer an opinion...
Access to MOOC platforms has barriers: there is a lack of accessibility to educational resources, communications tools and even the personalisation of user interfaces. Added to this are difficulties such as the need to develop specific digital or even social skills for those students with functional diversity. Therefore, a vision of the different strategies in relation to the achievement of accessibility...
This article questions the limits and possibilities of interaction between blind users and cooperative Web text editors. The study is a qualitative, exploratory/explanatory research which has as the object of study the implementation of live regions, accessibility tools that increases interaction possibilities and positive interdependence between blind user and Web applications. Based o the sociocultural...
Find areas and indicators of achievement where students need to reinforce their knowledge is a difficult task for teachers in schools. This article presents a decision-making support system that allows teachers to identify students with poor academic performance. The strategy is a Matrix Based Recommender System to rate assessments and share the results using statistical graphs. To validate this proposal...
Most visual languages are not purely graphical but include textual labels to complete the picture. However, in some languages labels tend to become rather long and thereby enlarge diagrams considerably. Since today's state-of-the-art development tools usually display diagrams in full detail, users must often scroll through the diagram or zoom out until the diagram fits inside the available drawing...
Programming environments and game environments share many of the same characteristics, such as requiring their users to understand strategies and solve difficult challenges. Yet, only game designers have been able to capitalize on methods that are consistently able to keep their users engaged. Consequently, software engineers have been increasingly interested in understanding how these game experiences...
We propose several new concepts for providing enhanced explanations of classifier decisions in linguistic (human readable) form. These are intended to help operators to better understand the decision process and support them during sample annotation to improve their certainty and consistency in successive labeling cycles. This is expected to lead to better, more consistent data sets (streams) for...
In software development processes, diagram editors play an important role. For instance, editors for creating UML diagrams are often used in early stages of software development. Three input methodologies can be distinguished: traditional mode-based editing, sketch-based editing, and gesture-based editing. Most of today's diagram editors are mode-based and use the mouse as an input device. (Multi-)touch...
The Data on the Web Best Practices Working Group, as part of W3C Data Activity, is standardizing the Data Quality Vocabulary (DQV) for expressing data quality of datasets published on the Web. By exploiting such DQV-based quality metadata associated to the datasets in a data portal, data consumers can achieve data quality-based filtering and ranking of datasets on the portal's conventional search...
