The invention discloses a text evaluation data specialization level analyzing method for electronic commerce. The text evaluation data specialization level analyzing method for the electronic commerce comprises the following steps of (S1) acquiring concept hierarch trees relevant to evaluation text data of all commodities; (S2) calculating a specialization level value of the evaluation text data on each concept hierarch tree; (S3) synthesizing values of all the concept hierarch trees and calculating specialization level of the evaluation text data; and (S4) dividing the specialization level of the evaluation text data into a plurality of grades to obtain specialization level grades of the evaluation text data of all the commodities and recommending the commodity evaluation text data with high specialization level to users. By the technical scheme, the users can directly and objectively acquire evaluation data, and contents of the evaluation data are quantified and are sorted objectively according to the grades.

The invention relates to a refrigerator with a demonstration mode and a running method of the refrigerator. The refrigerator comprises a body and a door fixedly arranged on the body, wherein a controller for controlling each part of the refrigerator is arranged in the refrigerator, and is used for controlling the refrigerator to enter the demonstration mode according to a received instruction of entering the demonstration mode, and controlling a refrigeration system of the refrigerator not to work and controlling other systems except the refrigeration system to normally work in the demonstration mode. The refrigerator has the demonstration mode, so that the shortcoming of poor display effects when the refrigerator is sold in a shopping mall is overcome.

The invention discloses a network commodity marketing device capable of storing audio and video. The network commodity marketing device comprises a database server (1) for storing commodity data and client data of a solid shop; an IM server (2) for providing instant communication services; a WEB server (3) connecting the IM server and the database server, wherein, the WEB server provides a customer client machine to access commodity information and judges whether the customer client machine is provided with a webpage built-in IM plug-in unit, if no, the WEB server transmits the IM plug-in unit to the customer client machine for installation; a merchant client machine (4) which is connected with a video input device (41) and an audio input device (42), arranged in the solid shop and provided with IM software, and performs real-time communication with the customer client machine after logging on the IM software.; and a mail server (5) which is connected with the database server (1), the IM server (2) and the WEB server (3), and is used for providing mail transmission and receiving services among the merchant client machine (4), the customer client machine and the database server (1).

Disclosed is a method for identifying social relation of persons in an image, comprising : generating face regions for faces of the persons in the image; determining at least one spatial cue for eachof the faces; extracting features related to social relation for each face from the face regions; determining a shared facial feature from the extracted features and the determined spatial cue, the determined feature being shared by multiple the social relation inferences; and predicting the social relation of the persons from the shared facial feature.

The invention discloses a light interactive advertisement realization method. In the method, advertisement terminal equipment with an operation function and an advertisement server connected with the advertisement terminal equipment by virtue of a network are arranged; and the method comprises the following steps that: firstly, the advertisement terminal equipment plays an advertisement endowed with corresponding response event; secondly, an advertising audience performs interactive operation on the advertisement terminal equipment, and the advertisement terminal equipment judges whether the interactive operation is correct in real time, if yes, the interactive operation information is received, if no, the operation is not responded; and after the step is completed, the advertisement terminal equipment judges whether the interactive operation information needs to require new data resource, and executes corresponding operation according to the judgment result. The light interactive advertisement realization method can be used for creating a brandnew advertising mode, breaking through the single playing mode of the traditional outdoor advertisement, and increasing the interaction link for audiences and the advertisement, thereby greatly improving the perception and impression of the audiences to the advertisement.

The present invention discloses a method, device and system for sharing intelligent wearable device data in real time. The method comprises: matching friends for the users who wear the intelligent wearable device according a preset rule; obtaining the users' state information who wear the intelligent wearable device in real time; and automatically sending the state information to intelligent wearable devices worn by the matching friends. The method, device and system for sharing intelligent wearable device data in real time obtain the state information of the users who wear the intelligent wearable device in real time and automatically send the state information to the intelligent wearable devices worn by the matching friends so as to realize the real-time sharing of the users' state, enrich the social data between the users' friends and facilitate getting more details about the users' life habit by friends.

The invention provides a method for enhancing the contrast, which is suitable for a display device, wherein the display device comprises a back light module and has a maximum brightness value. The method for enhancing the contrast comprises the following steps: receiving picture signals continuously in each unit time; calculating the proportion of a picture brightness value corresponding to each picture signal and the maximum brightness value continuously and setting the proportion as instantaneous relative brightness; setting a first proportion, first adjusting time, a second proportion and second adjusting time; adjusting and lowering the brightness of the back light module to minimum brightness gradually in the first adjusting time when the instantaneous relative brightness is smaller than the first proportion; and adjusting and increasing the brightness of the back light module to maximum brightness gradually in the second adjusting time when the instantaneous relative brightness is greater than the second proportion.

The invention provides a remote supervision relation extraction method and device based on consistency text enhancement, and the method comprises the steps: dividing a plurality of sentence instances according to entity pairs and relation labels, and obtaining a plurality of sentence packages; adopting different text enhancement methods for each sentence instance in each sentence packet, and obtaining a strong enhancement sample and a weak enhancement sample corresponding to each sentence instance in each sentence packet; determining a noise sample, and training the relation prediction model through the unrelated sentence instance and the strong enhancement sample and the weak enhancement sample of the noise sample to obtain a trained relation prediction model; and predicting a to-be-predicted sentence package by using the trained relationship prediction model to obtain a relationship label corresponding to the to-be-predicted sentence package. According to the method, the scale of a data set can be increased through consistent text enhancement, the generalization learning ability of the model can be enhanced, and the NA category and noise sample constraint model can learn more supervision information.
