Automatic processing of mathematical information on the web imposes some difficulties. This paper presents a novel technique for automatic generation of mathematical equations semantic and Arabic translation on the web. The proposed system facilitates unambiguous representation of mathematical equations by correlating equations to their known names. The ability to extract the equation meaning from its structure is vital when searching for mathematical equations. The general structure of the equation is recognized to identify the equation meaning. On the other hand, people who cannot understand Latin script notation of mathematical expressions have difficulty when they try to read them on the web as it is available mostly in Latin. Arabic mathematical expressions flow from right to left and they use specific symbols. The proposed system automatically translates the mathematical equations from Latin to Arabic. This translation can be combined with the text translation of mathematical web contents (generated by online tools) to be recognized by the people who understand only Arabic text. The proposed system is implemented using Java and it is evaluated using a set of web pages with MathML contents which is rendered in Mozilla web browser.
