Web19 Jan 2024 · Topic modeling is an unsupervised machine learning approach with the goal to find the “hidden” topics (or clusters) inside a collection of textual documents (a corpus). Its real strength is that you don’t need labeled or annotated data but instead it accepts the raw text data as input only, and hence why it is unsupervised. WebThe clustering method introduces the goal of achieving privacy of edge, node, and user attributes in the OSN graph. This clustering approach proposes to ensure k-anonymity, l-diversity, and t-closeness in each cluster of the proposed model. We first design the data normalization algorithm to preprocess and enhance the quality of raw OSN data.
