论文心得。

把搜索分为三种类型：informational, navigational, transactional
The classifications of informational, navigational, and transactional represent the type of content estination the searcher desired as expressed by their query.
结论发现
Our findings show that more than 80% of Web queries are informational in nature, with about 10%
each being navigational and transactional.
三种不同搜索的特点：
Navigational Searching
• queries containing company/business/organization/people

• queries containing domains suffixes
• queries with “web” as the source
• queries length (i.e., number of terms in query) less than 3
• searcher viewing the first search engine results page
Transactional Searching
• queries containing terms related to movies, songs, lyrics,
recipes, images, humor, and porn
• queries with “obtaining” terms (e.g., lyrics, recipes, etc.)
• queries with “download” terms (e.g., download, software,

• queries relating to image, audio, or video collections
• queries with “audio”, “images”, or “video” as the source
• queries with “entertainment” terms (pictures, games, etc.)
• queries with “interact” terms (e.g., buy, chat, etc.)
• queries with movies, songs, lyrics, images, and multimedia or

• queries that were beyond the first query submitted
• queries where the searcher viewed multiple results pages
• queries length (i.e., number of terms in a query) greater than 2
• queries that do not meet criteria for navigational or
其实本文采用的方式还是手动的，过程是，随机选出一些query，然后手动地进行分类，总结每个分类的特点，然后再随机选query，用刚才总结的特点进行分类，再进行总结，如此往复迭代。
