Task Environment and their Characteristic for SMS Spam or Ham Filter. The mapping process is simply a rule-based matching algorithm which is here Naïve Bayes ?. Theoretical AI Concept Regarding Spam or Ham ClassifierĪs already mentioned, we will make this project from the aspect of Artificial Intelligence course concepts so, let’s understand the agent.Īs the project is simple to design i.e., the agent can classify the incoming text(message) as ham or spam only thus based on the agent type this project agent falls under simple reflex agent as it takes action based on alone the current environmental situation i.e., it maps the current percept into proper action ignoring the history of percepts.Then, we will develop the Python web-based SMS text spam or ham detector. This is three parts of blog series, where we will understand the in and out of spam or ham classifier from the aspect of Artificial Intelligence concepts, and work with various classification algorithms in jupyter notebook and select the one algorithm based on performance criteria. Thus, using the knowledge of artificial intelligence with the amalgamation of machine learning, and data mining we will try to develop web-based SMS text spam or ham detector. As more significant numbers of SMS messages are communicated every day, it is challenging for a user to remember and correlate the newer SMS messages received in context to previously received SMS. SMS spam detection is an important task where spam SMS messages are identified and filtered. When the user realizes that the message is unwanted, he or she will be disappointed, and also SMS spam takes up some of the mobile phone’s storage. People classify SMS Spam as annoying (32.3%), wasting time(24.8%), and violating personal privacy (21.3%).Įvery time SMS spam arrives at a user’s inbox, and the mobile phone alerts the user to the incoming message. The low price and the high bandwidth of the SMS network have attracted a large amount of SMS spam. This pattern is observable by the results obtained by a simple SQL query on the spam corpus. Almost all of the spam messages ask the users to call a number, reply by SMS, or visit some URL. A look through the messages shows a clear pattern. SMS can have a limited number of characters, which includes alphabets, numbers, and a few symbols. Sending spam from a compromised machine reduces the risk to the spammer because it obscures the provenance of the spam. Commercial spammers use malware to send SMS spam because sending SMS spam is illegal in most countries. SMS spam is used for commercial advertising and spreading phishing links. SMS Spam in the context is very similar to email spams, typically, unsolicited bulk messaging with some business interest.

While the most widely recognized form of spam is email spam, the term is applied to similar abuses in other media and mediums. Spam is the abuse of electronic messaging systems to send unsolicited messages in bulk indiscriminately. SMS technology evolved out of the global system for mobile communications standard, an internationally accepted. Short Message Services (SMS) is far more than just a technology for a chat.
