The invention discloses a recognition method and device of ID (identity) card numbers and overcomes the defect that a mature method of recognizing ID card numbers from network data lacks at present. The recognition method includes: recognizing a character string, which may be an ID card number, from a character stream; verifying the character string, which many be the ID card number, according to ID card number encoding rules; using the ID card number, which may be the ID card number and which passes verification, as a positively effective ID card number. The recognition method and device of the ID card numbers according to the embodiment has the advantages that high-traffic webpage contents can be filtered and recognized in the network security field, accuracy is high, the speed is high, and small memory space is used in hardware equipment.

The invention discloses a method and device for recognizing a whole symbol string, and belongs to the field of natural language processing and research. The method includes the steps of extracting the symbol string contained in a text message, obtaining symmetrical symbol pairs from the symbol string, calculating the symmetry degree of the symbol string according to the obtained symbol pairs, and determining the symbol string as the whole symbol string if the symmetry degree of the symbol string meets the preset condition. The device comprises an extracting module, an obtaining module, a calculating module and a determining module. The symmetry degree of the symbol string can be calculated, whether the symbol string is the whole symbol string or not can be determined according to the symmetry degree of the symbol string without relying on an emotion symbol dictionary, whether the symbol string is the whole symbol string or not can be determined even when the symbol string is not contained in the emotion symbol dictionary, and therefore the problems that the recognition accuracy of symbol string information such as emotion symbols is low and the text message loss is prone to happening are solved, and the effect of improving the performance of a text message processing system is achieved.

The invention discloses a vertical text advertisement filtering method. The vertical text advertisement filtering method includes the steps of acquiring text information; grouping the text information in terms of lines, and generating a plurality of first text sequences sequentially; extracting characters corresponding to the first text sequences sequentially, and generating a plurality of second text sequences according to corresponding positions sequentially; filtering advertisements according to the second text sequences. The vertical text advertisement filtering method has the advantages that the second text sequences are generated through sequential extraction of the characters corresponding to the first text sequences in position, the advertisements are filtered according to the second text sequences, and accordingly vertical text information can be recognized effectively and the vertical advertisements can be filtered.

The invention discloses a character string processing method and device, and relates to the technical field of text information processing. The main purpose is to solve the problem that the Python language cannot filter characters whose ASCII code values are 0, resulting in that when the character string is transferred to other programming languages for processing subsequently, the contents of the character string read by the programming languages are incomplete; or resulting in that when the character string is processed by the Python language subsequently, the Python language still needs to read the characters whose ASCII code values are 0 in the character string. The main technical scheme of the character string processing method disclosed by the invention comprises the following steps: obtaining a to-be-processed character string; identifying whether characters whose American standard code for information ASCII code values are 0 in the to-be-processed character string; if so, deleting the characters whose ASCII code values are 0, and outputting and displaying the characters whose ASCII code values are not 0 in the to-be-processed character string. The character string processing method and device disclosed by the invention is used in a process of processing the characters whose ASCII code values are 0 based on the Python language.

The invention aims at proving a method and device used for obtaining target character strings in a disorder text, wherein a disorder text processing device obtains the disorder text to be processed, permutation and combination of characters in the disorder text is conducted, and one character sequence or a plurality of character sequences are obtained and correspond to the disorder text. According to the one character sequence or the plurality of character sequences, matching inquiry is carried out in a target pattern bank to obtain the target character strings in the disorder text. Compared with the prior art, due to the facts that the permutation and combination of the characters in the disorder text is conducted , the matching inquiry is carried out in the target pattern bank according to a result of the permutation and combination, and the target character strings comprising forbidding information in the disorder text are obtained, the forbidding information in the disorder text is effectively indentified, and therefore the capacity that a system applies and filters the forbidding information is enhanced.

The invention aims at providing a method and equipment used for cheating detection on interactive information in an interactive platform. The detection equipment obtains to-be-cheating-detected interactive information and detects whether the interactive information includes hot words in a hot word library or not. When the interactive information includes the hot words, the detection equipment obtains cheating attribute information of the interactive information. According to the cheating attribute information, the cheating detection on the interactive information is conducted through the detection equipment so that a corresponding cheating detection result of the interactive information can be obtained. Compared with the prior art, the detection equipment is used for detecting the interactive information which includes the hot words, the cheating detection on the interactive information is conducted according to the cheating attribute information of the interactive information, and therefore network environment of the interactive platform is optimized, and usage experience of a user of the interactive platform is improved.
