| Abstract: |
| An expanded Bull retrieval model -Salton model is introduced. The model units the vector retrieval with the Bull retrieval by applying weight value to the indexing terms, discussing Bull retrieval by utiliting the vector method to obtain a better formula which calculates the similarity. This model overcomes drawbacks of Bull retrieval in a certain extent. |
