Abstract The emergence of computer big data related data provides a new method for the construction of knowledge links in the knowledge map. This realizes an objective knowledge network with practical significance that is easier to be understood by machines. The article combines the four principles of linked data publishing content objects and their semantic characteristics, and uses the RDF data model to convert unstructured data on the Internet and structured data that adopts different standards into unified standard structured data for association. The system forms a huge knowledge map with semantics, intelligence, and dynamics.

Positive Results

A visual instructional tool that is theory-driven and supported by evidence-based research is used to support student learning and information-processing. The graphic organizer has enhanced learning in Science Education as well as Special Education, emphasizing the construction of knowledge with meaningful sequential relationships rather than memorizing isolated fragments of information. Students construct a visual schema that represents a system of interrelated concepts and icons created by the learner. This article provides a description of a qualitative application of how students with disabilities are able to represent their ideas by assimilating subject matter and their personal perceptions of content by drawing pictures connected to concepts within the visual graphic. Positive results were documented in this study.
