Abstract

The invention provides a method for searching names related to thematic words from a network. The method comprises the following steps of: searching web pages related to the thematic words in the network and filtering and analyzing the web pages; according to image nodes in the DOM (Document Object Model) tree of each web page, extracting image names and matching the image names with surrounding texts to form a candidate name first set; converting the DOM trees of the web pages into code sequences, determining repeated subsequences in the code sequences, and extracting candidate names corresponding to the repeated subsequences from the candidate name first set of the web pages to form a candidate name second set; filtering names in the candidate name second set according to preset rules and preset templates to determine the candidate names of the web pages; aiming at the candidate names from multiple web pages, filtering the candidate names according to a relationship between the candidate names or between the candidate names and the thematic words to obtain the names related to the thematic words; and calculating the score of each name and ordering the names according to the scores. The invention correspondingly provides equipment for searching the names related to the thematic words from the network.

In many cases (product research, market analysis, and strategy formulation), it is desirable to find the exact relevant product names for a particular topic, such as automatically finding all results for a category online. Such names exist on a large scale and change dynamically on the Internet. From a human point of view, identifying and categorizing these names from web pages is not a big problem, but it is very time consuming. In addition, users searching for a name often want to know product ranking information, such as which product is the m...
