A tag recommendation algorithm based on SCOT tag ontology

Responding to the problem of tag ambiguity and lack of tag semantics, we propose a new recommendation algorithm based on SCOT tag ontology. The algorithm utilizes rich semantics provided by SCOT ontology to expand tag co-occurrence and eliminate tag disambiguation based on tag semantic similarity for candidate tag sets, aiming to eliminate ambiguity tags and recommend semantic related tags, thereby improving the quality of recommendation. Experimental results show that the algorithm is effective.
