spam-prevention

问题 I am developing a spam filtering application. I need suggestions regarding the hybrid algorithm from Naive Bayes & SVM.(e.g. based on feature vector, probabilities). Any help is appreciated. Can we develop hybrid algorithm from Naive bayes & SVM? 回答1: Not sure why would you want to merge these two specific methods, but you could use ensemble learning methods for that. EDIT: based on your comments, it seems you already have two independently trained classifiers, and would like to use them

问题 I'm developing a web mailing app on Codeigniter PHP. I would like to know how to check SPF records are valid with PHP. Is there a PHP API to do this? This is so I can implement SPF within my mailing App to verify a user has authorized our servers via SPF DNS records to send mail. 回答1: Look at the libraries here: http://www.openspf.org/Implementations None are in PHP, but they are in other languages, so if you get stuck creating a validator according to the publish standards, you can see how

问题 I was wondering if I can send simple text to SpamAssassin. I want to put the comment in a text file and call 'spamc < file.txt' (i don't know if it is possible to send text direct to spamc). The problem is that SpamAssassin will report everything as spam if i don't specify headers or title ... Can i bypass all headers verification - or there is any mode where i can scan simple plain text ? (i don't have experience so I prefer to ask this. Thanks in advance) 回答1: I believe you can disable any

问题 I have a process which iterates String instances. Each iteration does few operations on the String instance. At the end the String instance is persisted. Now, I want to add for each iteration a check if the String instance might be spam. I only have to verify that the String instance is not "adult materials" spam. Any recommendations? 回答1: This is a very hard problem that the industry is constantly trying to solve. The best thing for you to do is to try and use an existing solution like

问题 How well does Django's anti-spam system in the comments framework work? Have you used it? What percentage of comment-spam does it prevent roughly? Is there anything else you do to help prevent comment spam on sites using the Django comments framework? 回答1: By default Django only offers a honey pot field and a hash check for spam prevention. It stops a lot of spam but absolutely not all. I'd guess at maybe 50-70% or so. For a very small site I have with less than 50 unique visitors per day,
