| Abstract: | Multi-document keywords extraction is carried out in many articles in the literature to identify best to reflect the overall theme of the keywords.Extraction algorithm for several keywords were introduced to analyze their respective advantages and disadvantages,in the TF/PDF algorithm,based on the use of literature and literature within a comprehensive inter-weighting method,presents a weight based on an integrated multi-document keywords extraction algorithm ITF/PDF.The ITF/PDF extraction results with TF/PDF extraction results were compared with experimental results show that,ITF/PDF can be more accurate in a multi-document extract the appropriate keywords. |
