Embodiment Construction
[0111] The technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Apparently, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0112] An embodiment of the present invention provides a multi-dimensional feature fusion similar event calculation method, such as figure 1 As shown, the method includes steps S1-S14.
[0113] Step S1: Obtain the current event subject word, current event abstract, current event title, current event argument, current event trigger word, current event life cycle, current event text category, current event named entity and current event occurrence location of the current event.
[0114] In the present embodimen...

The invention discloses a multi-dimensional feature fusion similar event calculation method and system, and electronic equipment. The method comprises the following steps: according to subject terms, abstracts, titles, arguments, trigger words, life cycles, and text types of a current event and historical events, respectively obtaining a subject term semantic similarity value, an abstract sentence semantic similarity value, a syntactic similarity value, an argument similarity value, a trigger word similarity value, a time window similarity value, and a text category similarity value of the current event and each historical event; performing weighted fusion on the plurality of similarity values to obtain similarity scores value of the current event and each historical event; when the similarity score values are greater than a preset threshold value, performing weighting according to occurrence places and named entities of the current event and the historical events to obtain weighted similarity score values; sorting the historical events according to the final similarity score values to obtain a sorting result, and determining the historical events with high similarity with the current event according to the sorting result. The accuracy of event similarity search is improved through multiple dimensions.
Description
technical field [0001] The present invention relates to the field of text analysis, in particular to a multi-dimensional feature fusion similar event calculation method, system, electronic equipment and storage medium. Background technique [0002] Existing public opinion analysis platforms are all analyzing the popularity and dissemination of ongoing events, but lack the comparative analysis of historical similar events. [0003] At present, historical events containing keywords are usually obtained based on keyword comparison or keyword search. This method is relatively rough for searching historical events and cannot obtain historical events with a high degree of similarity. Contents of the invention [0004] In view of this, the embodiments of the present invention provide a multi-dimensional feature fusion similar event calculation method, system, electronic equipment and storage medium to solve the defect of low similarity in historical event search in the prior art....
