Embodiment Construction

[0022] Other characteristics, objects and advantages of the present invention will become more apparent by reading the description of foreign name recognition with reference to the following drawings:

[0023] figure 1 It shows the flow chart of the method for automatic recognition of foreign names based on context semantics according to the first embodiment of the present invention. Specifically, this figure shows 4 steps, the first step is step S201, which analyzes the text to be recognized and Obtain the string set of candidate foreigner names. Then there is step S202, using the rule set of foreign names to modify and screen the candidate foreign name strings to obtain the first intermediate foreign name strings. Step S202 is followed by step S203, using probability statistics and a probability model to further screen the first intermediate foreigner name string set to obtain the recognized foreigner name set; and d. Recognized foreigner names.

[0024] Specifically, tho...

Abstract

The invention provides an automatic foreign name identification and control method based on context semantics in a natural language processing system by researching foreign name characteristics and combining a statistic probability model. The method is characterized by comprising the following steps of: a. analyzing a text to be identified and acquiring a candidate foreign name string set; b. correcting and screening the candidate foreign name string set by utilizing a foreign name rule set to acquire a first middle foreign name string set; c. further screening the first middle foreign name string set by utilizing probability statistics and the probability model to further screen the acquired identified foreign name set; and d. determining the unidentified foreign names according to the identified foreign name set. According to the system, the context characteristics of the names and the word characteristics of the foreign names are fully utilized, the identification error caused by word segmentation is greatly reduced, the condition that the other named entities are identified into names is well avoided, and the identification effect is improved.

Description

technical field [0001] The invention relates to the field of natural language processing, in particular to foreign name recognition technology in named entity recognition. Background technique [0002] Named entity recognition is a hot issue and basic work in natural language processing. It is of great significance to natural language processing and has been applied to many fields of natural language processing, such as information retrieval, information extraction and machine translation. Named entities generally include person names, place names, organization names, dates, times, etc. In various named entity recognition, the recognition of personal names has always been in an important position, and its recognition effect has an important impact on Chinese word segmentation. Chinese names include Chinese names and foreign names. At present, there are many studies on Chinese names and good results have been achieved, while there are relatively few special studies on forei...
