Embodiment Construction

[0017] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0018] figure 1 It is a flow chart of the natural language processing technology of the present invention. The invention provides a natural language processing technology applied to cell phone short message query. Such as figure 1 As shown, at first, the mobile phone user inputs a natural language text query sentence (step S101), such as "how to go from the airport to Hailong Building?" The word segmentation module processes, and the natural language text is divided into common words by means of a common word dictionary (step S102) , the sentence is divided into "from / airport / to / sea / long / building / how / go / ? / ". Then, the text is sent to the part-of-speech tagging module, which uses the part-of-speech dictionary and the feature dictiona...

Abstract

The invention provides a natural language treating technology used for mobile phone message query and a device thereof, which comprise the steps that: 1) the natural language texts are divided into frequent words; 2) the frequent words are marked by characteristics of the part of speech, and the query sentences are classified according to syntax characteristics; 3) the natural language texts belonging to communication information are selected; 4) the possible field entities are identified; 5) the correct entity words and possible entity string of words are identified. The technology and the device of the invention have the advantages that: the natural language treating technology is applied to a message query platform, so the clients do not need to remember complicated key in formats, and the key in method is similar to that of a common message, which is more user-friendly. Through the technology and the device of the invention, the query sentences that are keyed in by clients with natural languages become words that can be understood by the system, and the geographical entity words mastered by the system constitute a joint query, which is convenient for the further treatment of the later geographical navigation system.

Description

technical field [0001] The invention belongs to the technical field of extended functions of mobile phones, and in particular relates to a natural language processing technology and device applied to short message query of mobile phones. Background technique [0002] Currently, the application services on SMS do not have natural language processing technology, so they can only be simple customized services, etc. Users need to learn to send specific information such as codes to perform simple applications. For applications with complex user needs such as search and routing, this method is far from meeting the requirements, and it will also cause poor user experience due to cumbersome operation steps. [0003] One of the characteristics of mobile phone users is the problem of high input error rate caused by mobile phone input methods. At present, most of the input methods on mobile phones are pinyin input, and the number of phrases and ease of use are far inferior to computer ...
