semantic gap

The difference between the complex operations performed by high-level language constructs and the simple ones provided by computer instruction sets. It was in an attempt to try to close this gap that computer architects designed increasingly complex instruction set computers.

semantic gap

The difference between a data or language structure and the real world. For example, in order processing, a company can be both customer and supplier. Since there is no way to model this in a hierarchical database, the semantic gap is said to be large. A network-structured database could handle this condition, resulting in a smaller semantic gap. See semantics.

Many steps have been implemented toward reducing the semantic gap. Different methods were presented in our research based on different algorithms which depend on visual phrases (probability distribution, decoding, and generation of descriptive visual phrase), where the visual phrase is a collection of visual words that makes the image nearest to its semantic meaning.
