Embodiment Construction

[0016] The invention discloses a Chinese event representation method oriented to cognitive analysis, such as figure 1 As shown, the method includes the following steps:

[0017] S1: Input the Chinese text to be processed, and perform two preprocessing of format adjustment and sentence segmentation;

[0018] S2: Use natural language processing tools to analyze the text syntactically, accurately identify the subject, object entity and predicate verb, and identify the time and place entities in the corresponding sentence;

[0019] S3: Extract event information based on the event representation model, including the time and location of the event and its latitude and longitude code, the initiator and recipient of the event and their country, event action, event reporting time, number of repeated reports and original information source ;

[0020] S4: Determine the nature of the event, according to the event action information extracted in step S3, assist in considering the social ...

Abstract

The invention discloses a cognitive analysis-oriented Chinese event representation method, provides a structured event representation model and provides a Chinese text analytic processing-based assignment method of key attributes of the event type and the like. The cognitive analysis-oriented Chinese event representation method supports attribute extraction and presentation of social events in the fields of politics, military, diplomacy and the like; and the realistic feasibility is provided for representation, organization, storage management and cognitive analysis application of massive event data.

Description

technical field [0001] The invention relates to an event representation method, in particular to a cognitive analysis-oriented Chinese event representation method. Background technique [0002] An event is a knowledge unit that links elements such as participants, time, place, and behavior, and can reflect movements and changes in the real world. Massive Internet and other information sources contain a large number of various social events expressed in text form. Events are the main body of text descriptions such as news. Taking cognition as the goal, establishing an event model and realizing the extraction of event information, and clearly expressing the main semantic content of the information in a structured manner is the key to realizing the effective organization and machine understanding of massive text information. Foundation. Based on the cognition-oriented event representation model, extracting social event information in political, military, diplomatic and other ...
