There is currently no unified authoritative definition for third-generation search technology. Various companies are secretly developing it. It is understood that Google is preparing to develop next-generation intelligent search engines, including semantic search. Microsoft has also started researching search technology based on Web Blocks rather than entire web pages. Furthermore, human-powered search represents one of the ideas and examples of third-generation search engines. A site called "Tagee Grassroots Expert Network" is currently researching natural person search engines.
What is "Tagee (Tower Base)": Tagee is a combination of Tag and ee. Tagee refers to "experts categorized by Tag labels." On another level, it implies that Tagee is the foundation of all high towers.
Keyword search, represented by Yahoo!, is considered the first generation of search. The second generation of search engines, represented by Google, uses keyword plus website link analysis technology. There's no doubt about Google's current success, but search technology continues to evolve. The evolution of third-generation grassroots expert search technology could lead to the rise of a new company or perhaps even Google's downfall?
