WikiNizer™ Research (WikiNizeR) is a visual, Wiki-like knowledge organizer designed to construct Personal Knowledge Graphs by harvesting and contextualizing semantically structured information from Freebase as a linked data source.2 This tool enables users to visualize "meta" levels of reflection, facilitating sense-making and problem-solving processes.2 By integrating open web data within content-driven graph architectures of personal learning environments, WikiNizer supports the elaboration of dynamic graphs that articulate typed connections between 'Things' of interest, thereby enabling the emergence of novel concepts within complex content structures.23 It functions as a "self-curating" semantic knowledge management tool, supporting connectivist learning models and aiding in problem and project-based learning by helping define learning paths, workflows, and meta-level didactic structures.23 The system integrates web research, linked data, annotation, note-taking, and knowledge organization into a lifelong Personal Digital Archive of "born reproducible", ab initio re-purposable, and re-enactable Research Objects.2 The platform also supports collaborative knowledge work through a concept called Conceptipedia, a collaboration platform that allows users to compare, share, and merge their conceptualizations of a domain in the form of meta-knowledge graphs, turning semantic structures into visual Knowledge Architectures that consolidate ontological relations.356 This collaborative epistemology co-evolves meta-structures to the mutual benefit of users, making sense-making a social process of consensus building.36
