【摘要】：隨著手機(jī)用戶數(shù)量及短信業(yè)務(wù)的高速增長,尤其是網(wǎng)絡(luò)端可以向手機(jī)發(fā)送短信之后,垃圾短信泛濫已成為困擾通信運(yùn)營商和手機(jī)用戶的一個(gè)重大問題。垃圾短信主要有欺詐信息、假中獎(jiǎng)信息、廣告信息、色情信息等幾種。垃圾短信已經(jīng)影響到手機(jī)用戶的心情、生活和工作;對通信運(yùn)營商,垃圾短信也嚴(yán)重影響到其服務(wù)質(zhì)量的提高;欺詐類、非法廣告等短信甚至已經(jīng)違反法律法規(guī)。因此,迫切需要建立一個(gè)高效可靠的垃圾短信判定系統(tǒng)。本文主要進(jìn)行網(wǎng)絡(luò)端垃圾短信判定系統(tǒng)的設(shè)計(jì)和實(shí)現(xiàn)。首先研究垃圾短信的基本特征、傳統(tǒng)的垃圾短信判定方法、網(wǎng)絡(luò)端垃圾短信的特點(diǎn);其次,根據(jù)網(wǎng)絡(luò)端垃圾短信發(fā)送間隔時(shí)間短、量非常大、關(guān)鍵詞可能用拼音或同音字代替或用符號進(jìn)行分割等的特點(diǎn),結(jié)合傳統(tǒng)的過濾方法中的關(guān)鍵詞過濾,采用字符過濾、漢字轉(zhuǎn)拼音、字符串匹配、關(guān)鍵詞加權(quán)求和、根據(jù)長度進(jìn)行調(diào)整等技術(shù),設(shè)計(jì)一個(gè)基于界面事件驅(qū)動(dòng)的相對精確的高效垃圾短信判定系統(tǒng);最后用Visual Studio 2008和SQL SERVER 2005實(shí)現(xiàn)該系統(tǒng),并且進(jìn)行調(diào)試和測試。該判定系統(tǒng)是供通信運(yùn)營商使用的,應(yīng)結(jié)合包含接收者號碼、接收者的黑白名單、接收號碼數(shù)量等對發(fā)送號碼進(jìn)行過濾等號碼相關(guān)信息的客戶端一起使用。本文最終實(shí)現(xiàn)了對運(yùn)營商信息中心接收到的短信,統(tǒng)一濾去無效字符,并將有效字符轉(zhuǎn)為拼音,進(jìn)行關(guān)鍵詞匹配并計(jì)算權(quán)值和,然后根據(jù)權(quán)值之和與短信初始長度計(jì)算每24小時(shí)內(nèi)允許發(fā)送的次數(shù)。
[Abstract]:With the number of mobile phone users and the rapid growth of SMS business, especially after the network can send short messages to mobile phones, spam messaging has become a major problem for communication operators and mobile phone users. Spam messages are mainly fraud information, fake winning information, advertising information, pornographic information and so on. Spam messages have affected the mood, life and work of mobile phone users; for communication operators, spam messages have also seriously affected the improvement of their service quality; fraud, illegal advertising and other text messages have even violated laws and regulations. Therefore, there is an urgent need to establish an efficient and reliable spam SMS decision system. This paper mainly carries on the design and the realization of the network side spam short message judgment system. First of all, the basic characteristics of spam SMS, the traditional method of judging spam SMS, the characteristics of spam SMS on the network are studied. Secondly, according to the short interval time of sending spam SMS on the network, the quantity is very large. The key words may be replaced by pinyin or homonym or segmented by symbols, combined with the traditional filtering methods, such as keyword filtering, character filtering, Chinese character conversion to pinyin, string matching, keyword weighted summation, etc. According to the technology of length adjustment, a relatively accurate and efficient spam short message decision system based on interface event driven is designed. Finally, the system is implemented with Visual Studio 2008 and SQL SERVER 2005, and the system is debugged and tested. The decision system is for the use of communication operators, should be used together with the receiver number, the black and white list of recipients, the number of receiving numbers to filter the number of sending numbers and other information related to the use of the client. Finally, the text message received by the operator information center is realized, the invalid character is uniformly filtered out, the valid character is changed into pinyin, the key words are matched and the weight value and, Then the allowed number of times per 24 hours is calculated based on the sum of weights and the initial length of the message.
