Formal Concept Analysis (FCA) is a principled way of automatically deriving ontology from larger textual data and interested by many researchers. Central of FCA is a pure and well defined formal context. Exploiting documents with characteristic words to form formal context, denoted as textual formal context (TFC), which lead to generate a highly sparse two-dimensional space with lots of noise. It...
This paper presents the development of a formative assessment ontology, called Onto Note F, that enables teachers to add a formal semantics to formative feedback annotations they put on students' lab reports in Lab Book system. It is linked to a learning domain ontology enabling teachers to give formative feedbacks to students on expected lab work tasks. Onto Note F is developed following a rigorous...
Concept Maps (CM) are custom-made graphical representations whose understanding (and therefore socialization and reuse) depends on adequate explanation by the author and so their main advantage is also their main constraint: the freedom to represent concepts and relationships between them in any way, mostly in idiosyncratic and not understandable ones. In this paper we show how information on meaning...
