The Research on Term Field Based Term Co-Occurrence Model

This paper proposes a term field based term co-occurrence model, which consults the concept of field in physics, interpreting how to get the functional relations of terms\´ correlation and their distance. The result of experiments illuminates that this model is not a "descending model" simply and there are two segments in the change trend of terms correlation in evidence, which interprets the phenomenon from linguistics practice that terms\´ correlation is almost a constant in a small distance.
