Semantic video search using tagsonomies

Taxonomy can be defined as a controlled vocabulary that establishes hierarchical or associative relationships between terms. One problem of taxonomy is that it depends too much on the human element; a library can acquire titles on any subject, but it is unreasonable to expect indexers to be experts in every field of knowledge (Steele, 2009). Another problem is a timeliness problem inherent in taxonomy; taxonomy needs to be agreed upon and codified into a classification prior to use by the indexers (Peters, 2009). This can lead to a situation where classification structures are not compatible with current knowledge.
