Semantic link network (SLN) is a type of knowledge map to manage Internet (IoT) resources by addressing on linking nodes with semantic relations and reasoning over semantic links. We developed a series of theories on SLN including theory of normalized forms based on the conception of schema, algebra model, semantic relation computing theory based on semantic basis and orthogonalization, reasoning (both rule-based and analogy) algorithms, and solutions for integrity protecting and consistency checking. Based on these, we also develop the event-object linked network model with a framework of two-layer semantic link networks to manage the event (changing) and object status data respectively. In this talk, we will introduce the normalization theory of SLN, the semantic relation computing, and the primary idea of EOLN, as well as the social network of Chinese Listed Companies by using EOLN model.
