Abstract
The present invention discloses a recognition method for a Chinese company name. The method comprises the following steps: establishing a company name knowledge base and a company name probability knowledge base, wherein the company name knowledge base comprises a place name word set, a company general name word set, a profession modification word set, and a company exclusive name prohibition word set, and the company name probability knowledge base comprises probability knowledge of a company name left neighboring word and probability knowledge of a company name right neighboring word; scanning a text, and performing word segmentation on the text; and completing recognition of company names beginning with a place modification and company names without a place modification separately. Speed of file recognition can be increased by using the recognition method for the Chinese company name provided by the present invention, and accuracy of the company name recognition is improved.
Description
Technical field
The present invention relates to the technical field of internet, is a kind of recognition methods of the Chinese enterprise name realized by determining right boundary specifically.
Background technology
Unknown word identification is a gordian technique in natural language processing, is widely used in the fields such as information extraction, information retrieval, automatic question answering, mechanical translation.When collecting the information on internet, Chinese enterprise name need be gathered, Chinese enterprise name is the one of unregistered word, have constituent complexity, enormous amount, title constantly change renewal, cannot be exhaustive etc. feature, be considered to the most indiscernible in the middle of specific term, bring very large puzzlement to natural language processing, especially translation and machine perception.
For the identification of Chinese enterprise name, domestic research mainly contains: utilize Hidden Markov Model (HMM) and join probability valuation formula evaluates the ability forming enterprise name in real text; Based on the Chinese mechanism name automatic identification algorithm of stacked conditional random field models; Based on the Chinese organization names automatic identifying method etc. of class language model.
In Chinese enterprise name, often there is multiple different word or phrase, ratio of components is abundanter, and by word and the randomness of word and the uncertainty of Name Length in enterprise name, the identifying that all result in Chinese enterprise name is comparatively difficult, and discrimination is not high yet.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of recognition methods of the Chinese enterprise name realized by determining right boundary.
The technical scheme that the present invention takes for the technical matters existed in solution known technology is:
The recognition methods of Chinese enterprise name of the present invention, comprises the following steps:
A, set up enterprise name knowledge base, comprise place name word set, enterprise's general term word set, industry decorations name word set and enterprise's proper name and forbid word set, each word set respectively correspondence comprises place name vocabulary, enterprise's vocabulary of the same name, industry decorations name vocabulary and enterprise's proper name banned word;
B, set up enterprise name probabilistic knowledge storehouse, comprise the probabilistic knowledge of individual Chinese character composition enterprise proper name;
C, scan text, carry out Chinese word segmentation to text;
D, when there is place name vocabulary in textual scan, continue its word below of scanning, if after 2-5 Chinese character, there is industry decorations name vocabulary and after industry decorations name there is enterprise's general term vocabulary in next-door neighbour time, the identification of triggering enterprise name;
E, judge whether the Chinese character between above-mentioned place name vocabulary and industry decorations name vocabulary comprises enterprise's proper name banned word, if comprised, stop identifying, do not comprise, gather and calculate the probability that these Chinese characters form enterprise's proper name, form proper name probability weight result of calculation;
F, judge whether proper name probability weight result is greater than threshold value, be greater than threshold value and then assert that current whole Chinese fragment from place name to last enterprise general term is Chinese enterprise name, be less than, stop identifying;
G, recognition result tissue export as " enterprise name with the beginning of place name decorations name ".
The recognition methods of Chinese enterprise name of the present invention, comprises the following steps:
A, set up enterprise name knowledge base, comprise place name word set, enterprise's general term word set, industry decorations name word set and enterprise's proper name and forbid word set, each word set respectively correspondence comprises place name vocabulary, enterprise's vocabulary of the same name, industry decorations name vocabulary and enterprise's proper name banned word;
B, statistics information news data obtain the left adjacent Word probability knowledge of enterprise name; Set up enterprise name probabilistic knowledge storehouse, comprise probabilistic knowledge and the left adjacent Word probability knowledge of enterprise name of individual Chinese character composition enterprise proper name;
C, scan text, carry out Chinese word segmentation to text;
D, when scanning, industry decorations noun remittance abroad is current, and whether continue scanning and be close to thereafter and occur enterprise's general term vocabulary, if next-door neighbour occurs, and current vocabulary is not identified as " enterprise name with the beginning of place name decorations name ", then trigger enterprise name identification;
E, with industry decorations name vocabulary for starting point, vocabulary is turned left scanning one by one, judges whether left side vocabulary is present in enterprise's proper name banned word, if existence, stops identification;
Chinese character in left side vocabulary in F, acquisition step e, and gather the probability of their formation enterprise proper names of weighted calculation, obtain simultaneously this vocabulary more left side word " the left adjacent Word probability of enterprise name ", according to Hidden Markov probability model, calculate the identification probability of current left side vocabulary as the whole enterprise name of proper name;
G, to continue toward left scan vocabulary, the vocabulary of vocabulary on the left of this and step e is combined and treats as enterprise's proper name, repeat step F, until proper name Chinese character number is greater than 5 terminations;
The multiple identification probabilities obtained in H, G step, reject the result that probable value is less than threshold value, select one group of maximum result, as final recognition result;
I, final recognition result tissue export.
The advantage that the present invention has and good effect are:
The recognition methods of Chinese enterprise name of the present invention, comprise the following steps: set up enterprise name knowledge base and enterprise name probabilistic knowledge storehouse, enterprise name knowledge base comprises place name word set, enterprise's general term word set, industry decorations name word set and enterprise's proper name and forbids word set, and enterprise name probabilistic knowledge storehouse comprises the left adjacent Word probability knowledge of enterprise name and the left adjacent Word probability knowledge of enterprise name; Scan text, carries out participle to text; Complete respectively with the enterprise name identification of place name decorations name beginning and the enterprise name identification without the beginning of place name decorations name.Utilize the recognition methods of Chinese enterprise name of the present invention can speed in speed up document identification, and improve the accuracy rate of enterprise name identification.
