Embodiment Construction

[0019] Such as figure 1 As shown, an object-level knowledge mining system includes a data collection module 100 for collecting information from the Internet, which includes a WEB grabber 110, a data adapter 120, and a data converter 130.

[0020] Wherein, the WEB grabber 110 obtains a required webpage from a predefined URL list, and then obtains related information from the obtained webpage to form an object.

[0021] Generally, only the list to be crawled can be defined in a general web crawler, and then the content of these web page lists are directly captured in source code based on these lists. Therefore, common web crawlers have the following two Two problems: 1. The information that the user needs may be located in multiple related webpages; 2. It is impossible to obtain the relevant information from the webpage to form the object content that the user needs, and remove irrelevant information.

[0022] The WEB grabber 110 according to the present invention classifies web pa...

Abstract

The invention discloses an object-level information excavation system, which comprises a data collection module, a data cleaning module, a content pretreatment module and an object correlation search module, wherein, the data collection module used to collect data comprises a WEB grabber, the data cleaning module used to process structured data comprises a data verification module and a repeat-ridding process module, the content pretreatment module used to pretreat unstructured data comprises a metadata management module and a content analyzer, and the object correlation search module used toanalyze the correlation degree of the processed content of the content pretreatment module comprises a correlation degree analyzer. The invention also discloses an object-level information excavationmethod, which comprises the following steps that: information is collected from web pages; the data cleaning process is carried out to the structured data collected; the content pretreatment operation is carried out to the unstructured data collected; the object correlation search operation is carried out to the content obtained after the pretreatment.

Description

Technical field [0001] The invention relates to computer network technology, in particular to a method and system for object-level knowledge mining based on Internet information. Background technique [0002] With the development of the Internet, various kinds of information have increased exponentially. It will be very difficult to obtain useful information through artificial means. Therefore, how to obtain the required content from this massive amount of information and make it useful? Knowledge presentation will become a very important key point, so as to avoid being submerged in the information explosion. [0003] The current search engine is only full-text search, it only provides a lot of information, but does not form a useful knowledge, so users need to find out what information is useful in the search results according to their own knowledge background. In order to have a deeper understanding of the relevance of a certain information, users also need to analyze it themse...
