and under the condition that the negative keywords are searched in the name of the media publishing source and/or the media information published by the media publishing source, the corresponding media publishing source and/or the corresponding media information are regarded as items needing to be screened out.
In some embodiments of the present application, further, as shown in fig. 1, the method for fast screening news sources further includes the following steps:
step 108: judging whether the occupation ratio related to the preset dynamic front keyword library in the media information issued by the media issuing source is higher than a third preset threshold value: if not, the corresponding media publishing source is screened out from the news data source utility library.
In some specific implementations of the present application, the positive keywords may be respectively matched with the tags and titles in the news database, the keyword or title hit is the data hit, and the data source is retained if the news data hit rate under a certain data source meets a certain threshold.
