The Library of Congress and Semantic Search
May 14, 2008
The buzz about semantic search is rising. Powerset’s demonstration using Wikipedia data has triggered interest in searching in more intuitive ways. I received a news item about Semantra http://www.semantra.com, another player in this search market segment.
The Library of Congress is in the game too.
There’s an interesting news item “Semantic Search the Library of Congress”. To see how the US government approaches “beyond search”, navigate to http://lcsh.info/sh95000541. Once you have this url in your browser’s address bar, you can open a new window, and use this url to get a list of LCCNs to search semantically.
http://lcsh.info/.
The search result is a list of Use For terms, Narrower Terms (each of which is a hot link to more terms), the LC Classification, the date the entry was created, the date the entry was modified and alink to the Concept URI.
You will want to navigate to ProgrammableWeb.com http://www.programmableweb.com/api/library-of-congress-subject-headings and check out their explanation.
Based on this demonstration, today’s semantic search engines are not likely to be challenged in a meaningful way by a US government initiative any time soon.
