The invention relates to the technical field of computer information processing, and discloses a method for extracting a telephone number from a text, which comprises the following steps of: pre-creating a special database group; performing word segmentation on the obtained text content to obtain a segmented word data set; aiming at the word segmentation data set, extracting telephone numbers in the word segmentation data set step by step according to the following rules: retrieving a continuous combined character string which is not lower than three Arabic numbers in the word segmentation data set, and summarizing the numbers into a digital text combination; starting to retrieve a continuous sequence combination of the first number and the number on the right side of the first number fromthe first Arabic number of the number text combination; and finally, speculating and extracting telephone numbers according to a pre-created special database group. The word segmentation data set isobtained for the text content, the digital text combination is screened out from the word segmentation data set, matching screening is carried out item by item according to the formats of the mobile phone number and the fixed telephone number, the telephone number obtained from the text content is more accurate, and the user usability is high.
Description
technical field [0001] The invention relates to the technical field of computer information processing, in particular to a method for extracting telephone numbers from text. Background technique [0002] Text data mining is an application-driven discipline that uses computer processing technology to extract valuable information and knowledge from text data. The type of data processed by text data mining is text data, which belongs to a branch of data mining and is closely related to machine learning, natural language processing, mathematical statistics and other disciplines. Text mining plays an important role in many applications, such as data collection, information extraction (such as Internet search), etc. [0003] Text information extraction is a basic technology of text data mining. Text information extraction is a technique to extract specific information from text data. Text data is composed of some specific units, such as sentences, paragraphs, and chapters, whil...
