Environmental changes of web 2.0 and enterprise market together with the changes in the market paradigm have created new customer conceptual needs. And this shows the technological limitation of current search system that could not follow the new trends. Especially, the appearance of Search 2.0 up to the front line develops rapidly because the ‘Search’, one of the cores among 6 elements (SLATES) for the enterprise knowledge management paradigm mentioned by Prof. McAfee performs a very important role in the basic concept of Web 2.0 and Enterprise 2.0
In addition, new developers who put up Search 2.0 to the front line try to challenge to the difficult subjects of unnecessary information overflow of most of the search engines that scatters information ‘too much’ which is different from what the needed search results of user. These developers try to restore the order to simple and indiscreet search method taking information wherever there are any of the keywords. The concept is to easily find the needed information without searching every individual result after automatic analysis in a short time and display by categories.
In case of semantic based search, Hakia and Powerset understand the queries searcher input and carry out semantic based search. Practically it provides better search results than Google for the relatively complex queries. It is especially excellent in the intensive subjects like pharmaceutical, legal, financial, scientific, literary fields of study. Rollyo, Swicki, Del.cio.us of user participating types provide services to users for their share and use of search role and bookmark. Vivismo and Ask that are characterized by clustering provide a search function that classifies the search results into new categories based on language and statistical analysis.
Together with these Yahoo Mindset and Collarity accomplish the advanced role of Search 2.0 through intent driven methods and individual search. As seen in the above case, Search 2.0 provides function like user participation, understanding the users’ search intent, automatic clustering of search results, automatic classification and individualization through the compounded technologies of strengthened functions in the current information search with the text mining and semantic technology. The new trend of search technology enables to countermeasure to quickly changing Web 2.0 paradigm and IT environment, and also enables to adapt to Enterprise 2.0 environment of enterprise environmental change.
