基于Web的法律咨询系统的设计与实现

Web-based Legal Consulting System Design and Implementation

针对法律案例多样化，且法律条文中通常都含有大量专业性很强的法律专用语，使得法律按照奈文来分析自身面临了很大难题，本文研究了基于Web的法律信息服务平台的设计与实现，将冗杂无序的网上法律信息进行统一搜集和分类。并提供了大量案例供用户阅读，为用户提供更多有价值的法律信息。系统主要功能有：商务实务查询，相关信息查询，用户权限管理，案例及其类别管理，法律法规及其类别管理，简易论坛，案例搜索，法律法规查询，相似案例查找等。本系统的核心功能是相似案例查找和关键字搜索功能。需要利用Lucene进行切词处理。相似案例查找功能逆向运用了KNN算法的思想，在切词处理后，形成空间向量，利用空间向量计算来分析两案例的相似度，从而实现了相似案例查找。为了实现关键字搜索功能，利用Lucene实现了对数据库中的案例的全文动态索引处理，从而提高了搜索速度和搜索精度。

Aiming at the law case diversification and contains a lot of specialized legal language in the law,a Web-based legal information service platform for the design and implementation,will complex disorderly conduct on-line legal information collection and classification of unity and provide a large number of cases for users to read,to provide users with more valuable legal information.System main features are：business practice for relevant information,user rights management, and the type of case management,laws and regulations and category management,and simple forum,case search,for laws and regulations,and other similar cases to find.The core functions of the system is similar to cases of search and keyword search function,use Lucene to cut the word processing.Find similar cases reverse the KNN algorithm using,after all word processing,translate into a vector space.Then,use the space vector computing to implement the similarity of the two cases,thus achieving finding a similar case.In order to achieve the keyword search function,use Lucene achieved in the database case handling by the dynamic index,so as to enhance the search speed and accuracy of search.
