natural language query

A query expressed by typing English, French or any other spoken language in a normal manner. For example, "how many sales reps sold more than a million dollars in any eastern state in January?" In order to allow that query to be spoken aloud, both a voice recognition system and natural language query software are required.

Not Quite the Same as a Search Engine Query
A natural language query is based on the known identification of each data element that has been previously defined in a database, which means that the result should be extremely accurate. In addition, such queries are made against proprietary data within an organization. In contrast, while a search engine query supports natural language and may provide similar results, they are not guaranteed to be 100% accurate. However, after years of scouring the trillions of pages on the Web, search engine algorithms have derived the world's largest knowledge base of public data. See search engine.

* Searchable knowledgebases: Lang says Adobe maintains a technical solutions database of almost 5,000 documents that users can search by keyword or by natural language query, "which works very well for non-techie customers." Lang notes that Adobe tries to keep its knowledgebase as current as possible: "We add and delete new information every night."
