Abstract:

According to the semantic similarity calculation of traditional method in the presence of a large, complex calculation process problems, put forward a calculation method of comprehensive ontology similarity based on stage progression. The method to process the similarity is divided into four stages, each stage according to the actual situation of setting a threshold value, if the phase calculation of similarity is greater than a threshold, then calculate the similarity of the next phase, if less than the threshold then the concept of similarity between dissimilar, do not have to then calculate the following phases, this can greatly reduce the calculation of similarity, the calculation process and control. The algorithm in the recall and precision are increased by 4.78% and 3.05% than Glue algorithm through experiment data, while the calculation efficiency increased to 50% above.

Key words: stage progression, similarity, threshold
