Problems solved by technology

In order to define different relationships, different parameters need to be debugged, which will not only take more time in the process of defining relationships, but also define relationships are limited, making it difficult to describe more complex relationships
[0004] Therefore, it is very complicated to construct an event graph using the above method, resulting in poor event tracking ability and low efficiency for users to obtain event information

Embodiment 1

[0028] Refer to as figure 1 The flow chart of the construction method of the event graph shown in the method mainly includes the following steps S102 to S108:

[0029] Step S102, obtain multiple target event texts of the target event, the target event is an event that the user cares about or specifies, and may include political events, economic events, social events, and international events, etc. classified according to event content; each category Events can also be divided into finer-grained categories according to the event theme, such as social events can include fire events, postgraduate entrance examination registration events, pork price rise events, etc. The target event text is generally a large number of event texts for a certain event. For example, a large number of event texts about a fire event at a certain time and place obtained through multiple news platforms such as Sina and Sohu are target event texts.

[0030]Step S104, extracting meta-events from the targ...

Embodiment 2

[0065] Based on the method for constructing an event graph provided in the first embodiment above, this embodiment provides a device for constructing an event graph, referring to Figure 5 The structural block diagram of the construction device of the shown event graph, the device mainly includes:

[0066] A text acquisition module 502, configured to acquire multiple target event texts of the target event;

[0067] The original meta-event extraction module 504 is used to extract the meta-event from the target event text to obtain multiple original meta-events; the original meta-event includes the first event keyword;

[0068] A target meta-event determining module 506, configured to determine a plurality of target meta-events matching the event map from all original meta-events based on the preset event map and the first event keyword; wherein, the event map includes event causality and / or or events connected by event timing relationships;

[0069] The graph updating module ...

Abstract

The invention provides an event map construction method and device, and electronic equipment, and relates to the technical field of information mining, and the method comprises the steps of obtainingmultiple target event texts of a target event; performing meta-event extraction on the target event text to obtain a plurality of original meta-events; wherein the original meta event comprises a first event keyword; determining a plurality of target meta-events matched with the fact map from all the original meta-events based on the preset fact map and the first event keyword; wherein the cause map comprises events connected according to an event causal relationship and/or an event time sequence relationship; and updating the events in the cause map according to the target meta-event to obtain an event map corresponding to the target event text. According to the invention, the complexity of generating the event graph can be reduced, and the obtaining efficiency and event tracking capability of the event graph are improved.

Description

technical field [0001] The present invention relates to the technical field of information mining, in particular to a method, device and electronic equipment for constructing an event map. Background technique [0002] With the development of the Internet, when a news event (such as a fire event) occurs, the report text data about the event is large and scattered, which brings great obstacles to tracking and querying news events. [0003] Currently, there are two main ways to implement event tracking by building an event graph. One is to extract multiple meta-events first, and then extract the relationship between each meta-event. However, event relationship extraction is very complex. Traditional template-based relationship extraction has poor scalability. Supervised learning-based methods require a large number of labeled training samples, which is very time-consuming. The other mainly defines the relationship between different meta-events through multiple complex formul...
