枣品质决策系统对枣信息进行分词预处理 学位论文.doc

摘要 枣因其营养价值高，易种植，耐存活且在不同地域拥有不同特色而成为许多地方特别是山区高原致富之道，但由于技术方面的欠缺使得果农无法用专业知识去评估自己手中果实的品质和正确价值导向，由此带来一系列问题，信息消息的滞后导致农户盲目种植，产品积压，销售停滞。因此就要找到相关途径，知己之道，才能让枣农更快发展富裕起来。由此需求设计了《枣品质决策系统》，它是依托当前信息的网络化、快速化，使用网络评估果实品质，给出相关建议等服务为前提的综合信息评估服务系统的设计。通过短信接收果农给出的枣信息的初始描述，进行划句分词，得到相应的属性，并反馈给果农及专家。通过《枣品质决策系统》进行果实评估给出建议，方便即果农专家进行相关工作，又减少成本。缩短果农与专家的距离。 在此项目中选择了JavaWeb作为开发语言，用到了面向对象的开发思想和中文分词技术。在接口设计上，实现了数据封装和信息隐藏。 关键字：枣品质评估、JavaWeb、中文分词。  Abstract Dates because of its high nutritional value, easy to grow, resistance to survive and in different regions have different characteristics and become rich in many places, especially in mountainous plateau, but due to the lack of technology make the fruit cannot use professional knowledge to evaluate the quality of their own hands the fruit and the correct value guidance, leading to a series of problems, information messages delay lead to farmers planting blindly, product backlog, sales stalled. So will find relevant way, bosom friend, to get the most rich faster development. Thus demand jujube quality decision system is designed, it is relying on the current information network, rapidness, using the network evaluating fruit quality, and provide advice and other services as the prerequisite of comprehensive assessment information service system design. Through the description of the initial date information is presented in short message receiving fruit, is zoned word segmentation, to get the corresponding attribute, and give feedback to the farmers and experts. Through the jujube quality decision-making system to evaluate fruit recommendations, namely fruit experts for a related work, and reduce costs. Shorten the distance of growers and experts. In this project we select JavaWeb as a development language, use the object-oriented development thought and the design concept of the MVC design pattern. In the interface design, realized the data encapsulation and information hiding. Keywords: Jujube quality assessment , JavaWeb, Chinese Word Segmentation.
