Question routing method based on word vectors

ActiveCN104636456AOvercome the shortcoming that there is no co-occurrence word similarity of 0Improve accuracyData processing applicationsSpecial data processing applicationsLanguage modelCo-occurrence
The invention relates to a question routing method, in particular to a question routing method based on word vectors. The question routing method based on the word vectors includes the following steps that firstly, user files are established; secondly, data are preprocessed; thirdly, the word vectors are trained; fourthly, document vectors are expressed; fifthly, user authority is worked out; sixthly, user activity is worked out; seventhly, candidate answerers are ranked. The data are trained through word2vec, efficiency is high, the word vectors have the superposition property, and the defect that no co-occurrence word with the similarity of 0 exists among documents is overcome; meanwhile, document subject words are extracted, the document vectors are expressed by the word vectors, the authority, the activity and the similarity among the document vectors are worked out comprehensively, semantic information among the documents is considered, and noise is also reduced. Contrast experiments are carried out between the question routing method and classic TF_IDF and between the question routing method and a classic Language Model, and S@N of the question routing method is higher than those of the other two methods.

Plastic optical fiber network electricity checks meter system

The invention provides a plastic optical fiber network electricity checks meter system, and belongs to the field of power line information transmission. The checks meter system provided by the invention has strong anti-electromagnetic interference and nuclear radiation resistance as well as reliable performance; collected data has strong real-time performance, and low cost and high speed transmission of data are realized; the plastic optical fiber network electricity checks meter system is composed of electricity meters, a meter reading module, plastic optical fiber, a plastic optical fiber network switch and a data processing center; The signal flow direction of the checks meter system is as follows: an optic transmitter of the meter reading module converts an electricity meter signal to a network optical signal; the optical signal is coupled to the plastic optical fiber; an optical receiver of the meter reading module receives signals and reduces the optical signal to a network electrical signal; the plastic optical fiber network switch is used for data processing; and the data processing center is used to process data so as to complete the whole process of meter reading. The checks meter system provided by the invention has excellent anti-electromagnetic interference performance, strong security, high sensitivity and small volume, is simple to prepare, requires low cost, and has waterproof and moistureproof properties as well as long service life.
