From the beginning, the online education became evident the need for new ways of performing the process of teaching and learning, as in the special case of its evaluation, according to Rocha [1] “suffer interference from their singularities”. [2], [3], [4] and [5] also express concern with this peculiarity of online assessment. [6] motivated the creation of tools able to meet increasingly, this demand...
The Internet is a major source of online news content. Current efforts to evaluate online news content, including text, story line and sources is limited by the use of small-scale manual techniques that are time consuming and dependent on human judgments. This article explores the use of machine learning algorithms and mathematical techniques for Internet-scale data mining and semantic discovery of...
Global and national events in recent years have shown that online social media can be a force for good (e.g., Arab Spring) and harm (e.g., the London riots). In both of these examples, social media played a key role in group formation and organization, and in the coordination of the group's subsequent collective actions (i.e., the move from rhetoric to action). Surprisingly, despite its clear importance,...
Consistent with the assumption that the internalisation of parental and social values and behavioural expectations represents the most important influence on the formation of body boundaries (Fisher & Cleveland, 1958), and acts as a primary cause of psychological disturbances (Rogers, 1961), this study explored body boundary changes in person-centred therapy transcripts. The results demonstrated...
In this paper we present a framework that extracts meaningful knowledge from microposts shared in social platforms in order to build user profiles. This process involves different steps for the analysis of such microposts (extraction of keywords, named entities and their matching to ontological concepts) and their weighting. The concept weighting involves different scores, such as sentiment analysis...
Web pages are typical semi-structure data. Some tree-based models have been proposed to describe the semantic content structure of web pages in order to facilitate further content analysis. However, most existing models only present the segmentation hierarchy of content blocks rather than the semantic relationships among them. In this work, we propose a novel web page semantic structure model, called...
There are several invisible domains in knowledge organization system (KOS) that these domains need to investigate for improving our knowledge about them. Simplicity concept, which is emphasized by thesauri construction standards, is one of the important invisible domains in Knowledge organizations. Both the ISO 2788 and BS 5723 command leads thesaurus builders to the use of simple or unitary concepts...
Now a day's video blogs are playing an important role. To effectively manage the vlogs and make them more conveniently accessible for users is a challenging problem. In this paper we proposed a novel vlog management model which is consists of two stages: annotation and search. In Vlog annotation, we extract informative keywords not only from the textual content of the target vlog itself but also from...
Skin-color is proved to be powerful to pornographic images identification. However, skin-color is not determinant but heuristic. If we find documents with the same topic and some same keywords, we usually regard them as the same class. Based on this motivation, we proposed a well-defined semantic template, including topic template and bag-of-visual-words, to incorporate global semantics and local...
