Abstract: A system and method for searching through functions and expressions with symbols. Moreover, the system can be used to recognize and further analyze the notations of this nature and use this in order to translate, transform into audio, or solve the mathematical problems. According to at least some embodiments, the functions comprise mathematic equations which are defined by symbols and mathematic notation. The system and method enable a user to enter a mathematical equation in a WYSIWYG environment to a search engine, and to find similar or identical equations, first and foremost according to theoretical similarity, and secondly, according to visual similarity. The engine does this be understanding the meaning behind the visual symbols of the equation using a Dynamic Hidden Markov Model (hereon DHMM). The system enables the user to insert the equation with no prior knowledge of LaTeX, or any computing language, and with no need to follow a predefined generic protocol in order to insert the query.
