From Knowledge Transmission to Knowledge Construction: A Step towards Human-Like Active Learning

Cognitive Analytics: A Step Towards Tacit Knowledge?

Tacit Knowledge (TK) generally refers to information that is difficult to convey, store, or transfer explicitly. KT is a key challenge for corporations interested in capturing information in Knowledge Management (KM) systems that is generally lost with attrition or other human factors (e.g., dimensia). In particular, the challenge is in the capture of implicit information (e.g., additional rela...

A First Step Towards Automated Knowledge Integration

Knowledge integration is the process of incorporating new information into a body of existing knowledge (Murray and Porter, 1989). This process is a cycle of knowledge acquisition, formulation, recognition, elaboration, and adaptation. Knowledge acquisition is the act of gathering facts. These facts must be formulated into the language of the underlying representation of some knowledge base. Re...

Active Learning from Multiple Knowledge Sources

Some supervised learning tasks do not fit the usual single annotator scenario. In these problems, ground-truth may not exist and multiple annotators are generally available. A few approaches have been proposed to address this learning problem. In this setting active learning (AL), the problem of optimally selecting unlabeled samples for labeling, offers new challenges and has received little at...

Towards Nonmonotonic Relational Learning from Knowledge Graphs

Recent advances in information extraction have led to the so-called knowledge graphs (KGs), i.e., huge collections of relational factual knowledge. Since KGs are automatically constructed, they are inherently incomplete, thus naturally treated under the Open World Assumption (OWA). Rule mining techniques have been exploited to support the crucial task of KG completion. However, these techniques...
