Title of Lecture:

A Cognitive Content Recommendation Engine Empowered by Ontology-Based Semantics


Abstract: This research presents "A Cognitive Content Recommendation Engine Empowered by Ontology-Based Semantics", a novel framework designed to deliver smarter and more personalized recommendations by combining traditional content-based filtering with ontology-driven semantic reasoning. Unlike conventional systems that rely solely on keyword matching or user-item interactions, this engine integrates domain-specific knowledge graphs, natural language processing, and rule-based inference to understand deeper contextual meaning within content. By incorporating tools like CRFEntityExtractor and DIETClassifier, the system enhances entity recognition and intent understanding, allowing it to interpret unstructured text with higher accuracy.
One of the key strengths of this approach is its ability to address challenges such as cold start, lack of diversity, and semantic sparsity—common issues in content-based recommenders.
A key application of this system lies in the mental health domain, where personalized and context-aware support is vital. The proposed engine can recommend self-help resources, therapy content, or support group forums based on a user’s emotional state, behavioural cues, and language patterns—captured through their digital interactions. By understanding not just what users say but how they express their thoughts, the system delivers emotionally intelligent, non-intrusive recommendations aligned with individual mental well-being.
Evaluations on real-world social media datasets show notable improvements in relevance, diversity, and personalization compared to traditional models. By embedding semantic inference and user-centric design, this framework offers a scalable solution for sensitive domains like mental health, where trust, empathy, and context are critical to impact.
