In the embodiment of the application, an entity chain technology can be used for labeling the entities in the document. The process of entity chain technical labeling can be to analyze the document and find out the objects related to the participants in the news document such as company name, character name, etc.

304. And excavating the core entity.

And mining and analyzing the entity of the core description of the news document, wherein the entity of the core description of the news document is the core entity.

305. And extracting keywords.

After determining the core entities, keywords are extracted around the core entities, such as in the news in fig. 6 to 8: after the core entity is determined to be ' Baidu ' or ' Zhongtong ', the keywords which can be extracted include ' Xiao Ge express ', ' brush face ', real name authentication ' and the like.

306. And calculating the co-occurrence degree of the entity and the keyword.

The co-occurrence calculation is that the probability of co-occurrence of the entity and the keyword is calculated through historical data.

Determining keywords meeting the conditions according to the probability of the common occurrence of the core entity and each alternative keyword in a large amount of historical news data, namely deleting the alternative keywords with low probability scores and no information content in the plurality of alternative keywords, and finally remaining the keywords meeting the conditions.

For example: if the probability score of the co-occurrence of the Baidu and the real-name authentication is the highest, the real-name authentication can be selected as a keyword meeting the condition.

307. Keyword-tag mapping table.

The mapping table may be preconfigured.

For example: the mapping table contains the mapping relation of the keyword 'real name authentication' -label 'investment'.

308. And outputting the mapping relation of the entity, the label, the key word and the document.

The mapping relation between the entity and the label can be established through the keyword, for example, the mapping relation between the entity 'hundredth' -label 'investment' can be established through the keyword 'real-name authentication'.

Finally, a mapping relation of 'Baidu' -investment '-real name certification' -Zhongtong combined Baidu and 'check and correction' of the express xiaoge by brushing the face can be obtained.

The obtained mapping relation of ' Baidu ' -investment ' -real name authentication ' -Zhongtong combined Baidu ' to the express Xiaoge ' proved body-righting ' by face brushing is updated to the domain knowledge map, so that the whole news knowledge map can be updated.

The memory 1120 may be used to store software programs and modules, and the processor 1180 may execute various functional applications and data processing of the mobile phone by operating the software programs and modules stored in the memory 1120. The memory 1120 may mainly include a storage program area and a storage data area, wherein the storage program area may store an operating system, an application program required by at least one function (such as a sound playing function, an image playing function, etc.), and the like; the storage data area may store data (such as audio data, a phonebook, etc.) created according to the use of the cellular phone, and the like. Further, the memory 1120 may include high speed random access memory, and may also include non-volatile memory, such as at least one magnetic disk storage device, flash memory device, or other volatile solid state storage device.

The input unit 1130 may be used to receive a user selection operation and generate a key signal input related to user setting and function control of the cellular phone. For example: responding to the selection operation of the user on the target news event. Specifically, the input unit 1130 may include a touch panel 1131 and other input devices 1132. Touch panel 1131, also referred to as a touch screen, can collect touch operations of a user on or near the touch panel 1131 (for example, operations of the user on or near touch panel 1131 by using any suitable object or accessory such as a finger or a stylus pen), and drive corresponding connection devices according to a preset program. Alternatively, the touch panel 1131 may include two parts, namely, a touch detection device and a touch controller. The touch detection device detects the touch direction of a user, detects a signal brought by touch operation and transmits the signal to the touch controller; the touch controller receives touch information from the touch sensing device, converts the touch information into touch point coordinates, sends the touch point coordinates to the processor 1180, and can receive and execute commands sent by the processor 1180. In addition, the touch panel 1131 can be implemented by using various types, such as resistive, capacitive, infrared, and surface acoustic wave. The input unit 1130 may include other input devices 1132 in addition to the touch panel 1131. In particular, other input devices 1132 may include, but are not limited to, one or more of a physical keyboard, function keys (e.g., volume control keys, switch keys, etc.), a trackball, a mouse, a joystick, and the like.
