Embodiment Construction

[0039] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0040] Such as figure 1 Shown, the present invention comprises the following steps:

[0041] (1) Construct Chinese word segmentation database, place name address database and geographic feature word database.

[0042] Apply the word combination granularity reduction / expansion method of the Chinese dictionary to establish the Chinese word segmentation database DB1; combine the addresses of provinces, cities, counties, communities, streets or village groups to establish the place name address database DB2; measure, and establish the geographic feature word database DB3.

[0043] The specific establishment steps of the geographic feature word database DB3 are as follows: for a certain word word, its probability of belonging to DB3 is set as p, and the geographic correlation degree and semantic similarity measurement model is established:

[0044] p(word...

Abstract

The present invention discloses a method for matching a place name and an address in a news event based on geographical feature hierarchical segmented words. The method comprises the following steps of: establishing a Chinese segmented word database, a place name and address database and a geographical feature word database; acquiring a geographical feature word of a Chinese paragraph of the news event and a paragraph position of the geographical feature word; performing place name and address data matching and correlative judgement on Chinese segmented words in the paragraph position of the geographical feature word; and performing position association on the successfully matched Chinese segmented words of the news event, implementing place name and address coding, and determining a geographical coordinate position. According to the method, in combination with a geographical information system and a place name and address matching algorithm, the display and geographical association of the news event in a map are implemented; and the news event is converted from a one-dimensional text to a two-dimensional geographical space position, thereby acquiring news information more visually and vividly, and implementing automatic, accurate and fast matching and association of the place name and the address in the news event.

Description

technical field [0001] The invention relates to a method for matching place name and address data, in particular to a method for matching place name and address of news events based on geographical feature hierarchical word segmentation. Background technique [0002] In the real world, people can obtain important information they are interested in through various ways and channels—news events, such as electronic tools such as mobile phones and computers, or media tools such as newspapers and television. News events are also called "news", which refers to brief and rapid reports on people and facts of certain social value that have recently occurred at home and abroad. [0003] In the traditional way, people mainly learn about news by reading text descriptions or picture scenes of news events, but this way lacks an intuitive image of the scene, a lack of understanding of geographical location and a lack of grasp of the surrounding environment, so it is a kind of news acquisit...
