Somao software introduction
The software can only capture a part of a web page (it can be a joke, a novel, or even just the link address of a movie or MP3, depending on your configuration). With it, you can copy a website (or its link) in just a few hours.

The description and definition of crawling targets are the basis for determining how to formulate web page analysis algorithms and URL search strategies. The web page analysis algorithm and candidate URL sorting algorithm are the key to determining the service form provided by the search engine and the crawler web page crawling behavior. The algorithms of these two parts are closely related.
Existing descriptions of crawling targets by focused crawlers can be divided into three types: based on target web page characteristics, based on target data patterns, and based on domain concepts.
Based on target page characteristics
The objects crawled, stored and indexed by crawlers based on the characteristics of the target web page are generally websites or web pages. According to the method of obtaining seed samples, they can be divided into:
(1) Pre-given initial crawling seed sample;
(2) Pre-given web page categories and seed samples corresponding to the categories, such as Yahoo! classification structure, etc.;
(3) The crawl target samples determined through user behavior are divided into: (a) crawl samples marked during user browsing; (b) access patterns and related samples obtained through user log mining.
Among them, the webpage characteristics can be the content characteristics of the webpage, or the link structure characteristics of the webpage, etc.
Based on target data schema
Crawlers based on target data patterns target data on web pages. The captured data generally must conform to a certain pattern, or can be converted or mapped to the target data pattern.
Based on domain concepts
Another way to describe is to establish an ontology or dictionary of the target domain, which is used to analyze the importance of different features in a certain topic from a semantic perspective.
