摘要
高效可靠的数字化信息服务检索方法是数字化信息服务广泛应用的关键。传统的数字化信息服务检索方法采用关键字匹配度顺序检索的方法,由于检索对象的信息量巨大,检索效率低。提出一种基于多维曲径选择进化的数字化信息服务检索方法,根据检索标准,将信息分为多个维度,然后对多个维度进行曲径选择进化,提取信息的深层次特征,根据深层次特征,对数字化信息服务进行检索,提高系统检索的效率和可靠性。采用检索效率和检索正确率作为衡量标准,基于100组信息进行实际的分析,结果显示,基于多维曲径选择进化的数字化信息服务检索方法可以将检索效率和检索正确率提高39.3%和39.9%,具有很好的应用价值。
High efficient retrieving of digital information service was the key to digital information service. In traditional digital information service retrieval method, the keyword matching sequence retrieval method was used, due to the huge amount of information retrieved objects, the retrieval efficiency was low. A retrieving services method of digital information was proposed based on labyrinth choice multidimensional evolutionary approach, the information was divided into multiple dimensions, and then the multiple dimensions of the labyrinth evolution-depth feature information was extracted, according to in-depth features, the digitized information retrieval services was analyzed, the efficiency and reliability of the system was improved to retrieve. Retrieval efficiency and the correct rate of retrieval were taken as a measure, based on 100 group information, the results show that with multi-dimensional labyrinth evolution of digital information service retrieval method, the retrieve efficiency and retrieval accuracy are improved of 39. 3 % and 39. 9 % , it has good application value.
