The invention discloses a mathematical formula searching method and device. The device comprises a formula database, a database updating module, a man-machine operation module, a central processor and a retrieving module. The formula database is used for storing various formula data, interpretations corresponding to formulas and application case data corresponding to the formulas. The database updating module is used for updating the formula database through a 3G network and a Wi-Fi network. The man-machine operation module is used for inputting mathematical formulas needing to be inquired and sending the data to a data processor and also used for inputting information calling orders. The central processor is used for establishing indexes on the input mathematical formulas according to a rule and calling data information needed by people from the formula database according to the information calling orders and used for adding and deleting users, modifying passwords and managing the authority. According to the mathematical formula searching method and device, different input modes can be selected according to different formulas, the retrieving process is simple and fast, when a retrieving result is obtained, the principle introductions, application cases and other data of the formulas can be obtained, the time of users is saved, and use is convenient.
Description
technical field [0001] The invention relates to the field of search engines, in particular to a mathematical formula search method and device. Background technique [0002] With the development of Internet applications and the explosive growth of various types of digital content (text, pictures, audio and video, etc.), how to accurately find relevant content in massive information based on user input, It is a very basic and significant technical challenge. At present, general search engines such as Google and Baidu have solved this problem to a certain extent. [0003] However, general search engines and other software and network applications based on traditional text retrieval systems still have great limitations in searching for various mathematical, physical and chemical formulas and other symbols (such as staves, chemical molecular formulas, etc.) , so that it cannot meet the user's search needs in science education, scientific research engineering and even other aspe...
