摘    要:利用模糊数学综合评判模型,将科技查新题名分割为自然词,通过计算检索词之间的蕴含度,完成对检索策略过程的模糊量化处理,并利用权重矩阵进行检索词合适程度的综合评判,提取出最合适的检索词和最佳检索表达式。利用查新实例进行该模型的模拟计算试验,结果表明该模型提取的检索词及其组成的检索表达式比较符合实际情况,具有一定的客观性和准确性。

关 键 词:科技查新  检索策略  模糊数学  综合评判

Abstract:By using fuzzy comprehensive evaluation model,this paper segments the natural word of the science and technology novelty search title.By calculating the implication degree between the retrieval words,it completes the fuzzy quantization of retrieval strategy process.By using the weight matrix for comprehensive evaluation on the suitability of retrieval word,it extracts out the most suitable retrieval word and optimal retrieval expression.By using some examples for the model test,the results show that the extraction retrieval words and the retrieval expression is in accordance with the actual situation,and have the objectivity and accuracy.
Keywords:science and technology novelty search search strategy fuzzy mathematics comprehensive evaluation
