【摘要】：隨著互聯(lián)網(wǎng)的普及和應用，網(wǎng)絡媒介已成為繼報刊、廣播、電視三大新聞媒介之后的“第四媒介”，具有傳統(tǒng)媒介無法比擬的交互性、無界性和開放性。近年來發(fā)生的頻率越來越高的群體性事件，使公安工作面臨著相當大的壓力。幾乎每起群體事件背后，都有互聯(lián)網(wǎng)上的輿情在發(fā)揮著推波助瀾的作用。及時、迅速、準確地搜集和研判各種媒體，搶占輿論制高點，及時作出反饋和正面引導，向決策機關及時報告預警信息，有效消弭各種可能引發(fā)群體性事件的消極因素，迅速控制并平息各種不良事態(tài)，是近年來擺在各級公安機關面前的新課題。 網(wǎng)絡輿情監(jiān)控系統(tǒng)涉及技術領域跨學科，綜合應用比較復雜，主要包括搜索引擎技術、語義分析技術、中文信息檢索技術、概率學、統(tǒng)計學。 在系統(tǒng)設計時主要采用文獻研究和現(xiàn)實需求結合的調研方法，首先，分析公安網(wǎng)絡輿情監(jiān)控分析系統(tǒng)所需要應用的所有部門，如網(wǎng)監(jiān)處、政治處、刑偵支隊等，通過召開動員會、座談會及下發(fā)需求調查問卷，了解各部門的職責及具體需求情況，將需求信息進行搜集和整理。 確定公安輿情監(jiān)控系統(tǒng)的主要功能為：系統(tǒng)24小時不間斷對監(jiān)控網(wǎng)站的信息挖掘、智能分析工作，從中自動分析出公安部門所需要的有用信息，并開發(fā)出友好的邏輯功能與界面，為公安部門全面服務和應對涉警輿情的應急指導決策、提高社會綜合治安整治工作與社會維穩(wěn)工作提供技術支持。 在系統(tǒng)實現(xiàn)過程中，根據(jù)軟件開發(fā)理論與信息系統(tǒng)開發(fā)理論進行分析。根據(jù)第一階段需求調研后的結果，整理后對系統(tǒng)設計與開發(fā)進行內容規(guī)劃、確定目標。并結合與我廳信通處技術專家及專業(yè)技術公司得出的系統(tǒng)可行性分析，分析本系統(tǒng)所涉及的關鍵技術、實現(xiàn)方法，并設定其開發(fā)平臺及運行環(huán)境。 確定本系統(tǒng)采用分布式的系統(tǒng)架構來獲得對互聯(lián)網(wǎng)海量數(shù)據(jù)的按需獲取能力與存儲要求，確定采用Java語言開發(fā)，系統(tǒng)框架為S2+S+H（Struts2+Spring2.5+Hibernate3.2），，前臺信息檢索采用全文檢索，服務器中間件為Tomcat6.0，采用MS SQL數(shù)據(jù)庫。
[Abstract]:With the popularization and application of the Internet, the network media has become the "4th media" after the three major news media, newspaper, radio and television, which has the interaction that the traditional media can not compare. Unbounded and open. In recent years, the frequency of group incidents is increasing, making the public security work faced with considerable pressure. Almost every group event behind. Public opinion on the Internet is playing a role. Timely, rapid, accurate collection and evaluation of various media, seize the commanding height of public opinion, timely feedback and positive guidance. It is a new task for public security organs at all levels in recent years to report early warning information to policy-making organs, effectively eliminate all kinds of negative factors that may lead to mass incidents, and quickly control and quell all kinds of undesirable situations. The network public opinion monitoring system involves the technical field interdisciplinary, the synthesis application is quite complex, mainly includes the search engine technology, the semantic analysis technology, the Chinese information retrieval technology, the probability, the statistics. In the system design mainly uses the literature research and the reality demand union investigation method, first, analyzes the police network public opinion monitoring and analysis system needs to apply all the departments, such as the network supervision office, the political office. Criminal investigation detachment and so on, through the convening mobilization meeting, the forum and the dispatch demand questionnaire, understands each department's duty and the concrete demand situation, collects and collates the demand information. Determine the main functions of the public opinion monitoring system is: the system 24 hours on the monitoring website information mining, intelligent analysis work, from which to automatically analyze the useful information required by the public security department. The friendly logic function and interface are developed to provide technical support for the public security department to provide comprehensive service and emergency guidance and decision to deal with the police public opinion, and to improve the comprehensive public security and social stability. In the process of the system implementation, according to the software development theory and information system development theory analysis. According to the results of the first stage of demand research, collate the system design and development of content planning. With the analysis of the feasibility of the system with the technical experts and professional technology companies, the paper analyzes the key technology involved in the system, the realization method, and sets up its development platform and operating environment. It is determined that the system adopts the distributed system architecture to obtain the on-demand access and storage requirements of the massive data on the Internet, and the Java language is adopted to develop the system. The frame of the system is S 2S / Hu Struts2 Spring2.5 hibernate 3.2, and the front information retrieval adopts full text retrieval. Server middleware is Tomcat 6.0. MS SQL database is used.
