Abstract

fetched live from OpenAlex

As a consequence of the proliferation of multimedia contents, users are nowadays frustrated with the huge amount of available video information whose content is not targeted to their needs and preferences. Its challenging to analysis video content for video personalization due to the lack of semantic video summarization and retrieval techniques. In fact, most of current video personalization systems are using low-level features. However, users identify and select video content using high-level semantics. This creates a gap between user preferences and video content representation that must be bridged for video personalization systems.In this paper we present a new approach for video personalization based on domain knowledge. We first introduce an ontology based indexation approach to enhance retrieval performance. Then, we present a personalization strategy based on fine grained sequential pattern discovery. The proposed approach is based on both user and content personalization. The performance study and experiments show that the use of ontologies to index and represent video contents enhance running time and memory performances. This paper also describes VideoMiner, a system prototype that implement the proposed approach for video personalization.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
