specific Embodiment

[0059] In this embodiment, the designated field is "academic field". For the convenience of description, the first three items of the search results of each general search engine among vertical search engines and meta search engines are taken.

[0060] (1) if figure 1 As shown in S101, a user uses a mobile phone as a user terminal, submits the theme of "big data data mining" to the server through the browser HTTP protocol through the mobile phone.

[0061] (2) if figure 1 As shown in S102, the server receives the subject information of "big data data mining" submitted by the user terminal, and obtains a list of search records based on the vertical search engine module.

[0062] Vertical search engines use timers and incremental crawlers to collect data. The homepages of news websites of 75 colleges and universities affiliated to the Ministry of Education were used as seeds, and incremental crawlers were put into them. Using timer control, these websites are periodically cra...

Abstract

The present invention is applicable to the field of network information processing and provides a field subject-oriented Web news dynamic aggregation method. The method comprises the following steps of: for a field site list pre-defined by a user, according to a subject provided by the user, acquiring a search record list by utilizing a vertical search engine and a meta search engine; performing deduplication on the search record list and identifying a Web news webpage to obtain a news webpage search record list; with a Web information extraction method, acquiring a structured news list from the news webpage search record list; and performing ranking on the structured news list according to a field model to obtain an ordered structured news list, and returning the ordered structured news list to the user as a dynamic aggregation result. According to the field subject-oriented Web news dynamic aggregation method, a multi-source associated Web news set is acquired in real time according to a field and a subject provided by the user, an interactive mechanism where the ranking of the Web news depends on the popularity of the Web news is provided, and the purpose is to provide a convenient and efficient internet information acquisition and sharing mode.
