Abstract

The invention discloses a text indexing method and system based on the Storm stream computing framework, comprising: the realization of the topology of Storm, the design of the Storm real-time data processing framework, and the completion of the automatic web page extraction program of the web crawler; automatic keyword extraction; text classification, according to the text The content or properties of , group the text into one or more categories. The invention enables itself to rewind the backup data in the case of data damage, loss, etc., to realize data recovery; provides the function of centralized operation and maintenance of the system itself; beautiful and practical interface, convenient and intuitive graphical user management interface; function expansion meets The user's requirements for system expansion and expansion of the scope of use in the future; fault tolerance: when illegal data is generated due to user input or misoperation, the system has a certain fault tolerance mechanism.

Description

technical field [0001] The invention belongs to the technical field of data processing, and relates to a text indexing method and system based on a Storm stream computing framework. Background technique [0002] Storm is an open-source, big data processing system that, unlike other systems, is designed for distributed real-time processing and is language-neutral. Hadoop focuses on batch processing. This model is sufficient for many situations (such as indexing web pages), but there are other usage models that require real-time information from highly dynamic sources. To solve this problem, we have to use Storm (now called BackType in Twitter) by NathanMarz. Storm doesn't handle static data, but it handles streaming data that is expected to be continuous. Considering that Twitter users generate 140 million tweets (tweets) every day, it's easy to see the enormous uses for this technology. But Storm isn't just a traditional big data analytics system: it's an example of a co...
