The sentiment of a sentence or a comment can be detected more accurately by applying Word Embeddings. This article presents the idea of word co-occurrence matrix and Skip-Gram to determine the actual contexts of the words, Hellinger PCA to determine the most similar words and generate a sliding window of most probable context words around each word. It is shown that, by applying Word Embeddings to...
The integration of video conferencing systems (VCS) have increased significantly in the classrooms and administrative practices of higher education institutions. The VCSs discussed in the existing literature can be broadly categorized as desktop systems (e.g. Scopia), WebRTC or Real-Time Communications (e.g. Google Hangout, Adobe Connect, Cisco WebEx, and appear.in), and dedicated (e.g. Polycom)....
The current work blends the different paradigms of Question Answering systems and presents a content-aware hybrid architecture for an open-domain factoid questions. It combines a knowledge-based, information extraction-based and a web-based approach in a pipelined architecture to construct an answer to a question keeping the context and discourse of the question in view. The proposed semantic-aware...
In this paper, we aimed to guide about latest development and studies about students' performance analysis and Learning Analytics in Massively Open Online Courses (MOOCs) for researchers related with the topics. For this purpose short review for usage of performance prediction and Learning Analytics in MOOCs is investigated In our study, to help readers get familiar with our topic, firstly literature...
This paper makes a contribution to the development of computational archival science by thinking about and linking computational and archival thinking. It suggests that archival thinking and the archival problem space encompasses questions about the nature of consciousness, highlighting how these questions seem to be apparent within the fundamental archival principles of respect des fonds, provenance...
There is good amount of excitement around Massive Open Online Courses (MOOC), but not every MOOC is getting massive enrolments as expected, particularly if it isn’t free. Since MOOCs are expensive to create, getting higher enrolment is necessary for justifying their cost. This research paper reports on the attempt to identify key determinants of MOOC acceptance. Knowing these determinants can help...
Engineering decision problems often involve the simultaneous optimization of several conflicting criteria. Among multicriteria decision aid methods, PROMETHEE has gained a lot of attention during the last three decades. Despite its successful application in different fields, some researchers have emphasized that PROMETHEE does not respect the independence to third alternatives assumption. This leads...
Knowledge Management methods, techniques and experience can bring a considerable help in preventing all kind of risks. The current economic context amplified the existing risks and introduced new ones such as environmental, political and social. Among the most critical risks of this century is this of lost of knowledge and “memory” in particular in industry involved in long-term activities. After...
Technology Enhanced Learning is one of the most dynamic areas of inquiry in education. One form of TELs, that is on-screen learning, has been well understood to hinder learning experience due to the reading spatial instability, difficulties in establishing mental map, and poor visual ergonomics. This work intends to study to which extend a learning a recommendation system improving on-screen learning...
Within real-world social networks people are linked with multiple types of relationships, which brings new challenges in community detection for multilayer social network where each layer represents one type of relationships. However, most of existing approaches consist on transforming the problem into a classical problem of community detection in monoplex network. In this work, we propose a new hybrid...
Traditional Braille is a 6-dot code that can represent maximum 64 unique symbols with each braille cell. This is grossly insufficient to represent even ordinary English text (comprising 26 small letters, 26 capital letters, 10 digits, and 14 basic punctuations) — let alone math and science symbols. Thus a braille user has to enter 2 (and sometime 3 or 4) braille cells to enter one character or symbol...
Massive data applications such as E-science applications are characterized by complex treatments on large amounts of data which need to be stored in distributed data centers. In fact, when one task needs several datasets from different data centers, moving these data may cost a lot of time and cause energy's high consumption. Moreover, when the number of the data centers involved in the execution...
The lack of strong reading comprehension skills affects a student's success in school. This paper aims to examine how fluent and non-fluent readers process text and images by utilizing eye movement methodology. Three types of diagnostic instruments were used to collect data (text-only, text and image and image-only). The experiments also involved personal observation, interviews and Q&A sessions...
It is expected that muti-core systems will become the dominant computing platform in the next few years. However, the current programming models (such as Java, .Net etc.) do not scale well to exploit the computing power of such multi-core systems. In primitive programming paradigms there exist implicit dependencies between code and program states, and compilers cannot exploit the potential concurrency...
The overload of information can become a significant challenge in relation to information retrieval systems. Often users will need to carry out extensive research to get the information they desire. This issue will only become more challenging as the quantity of data available on the internet increases. This increase shows no signs of slowing down and inevitably demands better solutions. One such...
Detecting metamodel atomic changes during evolution is prerequisite for co-evolution of models, constraints, and transformations. They are also essential to detect complex changes over the sequence of atomic ones. However when detecting atomic changes with a difference-based technique, the applied order of the atomic changes is not recovered and some hidden changes are undetected. Thus, the quality...
A lack of educational strategies may hinder students from benefiting the most from their education. The existing public or government schools do not adequately accommodate children with special needs in terms of providing them with good syllabuses as well interventions. Instead, various forms of pervasive developmental disorders are frequently placed in special education classes without an accurate...
Making construals is a new digital skill that complements conventional programming. Its primary focus is on using computer-related technology to stage interactive experience of unprecedented richness and subtlety. This paper is a tutorial on the latest version of an instrument for making construals developed in the ongoing EU Erasmus+ CONSTRUIT! project. Its principal theme is the re-creation of "the...
Scrum is a cyclical project management technique whereby members of a development team work together to define product development strategies in pursuit of a common objective in an adaptable and incremental manner. We have found that Scrum is a promising approach for exposing students to project management of undergraduate engineering projects. But, the technique is not used often in undergraduate...
Despite the documented need to train and educate more cybersecurity professionals, we have little rigorous evidence to inform educators on effective ways to engage, educate, or retain cybersecurity students. To begin addressing this gap in our knowledge, we are conducting a series of think-aloud interviews with cybersecurity students to study how students reason about core cybersecurity concepts....
