AskWiki Beta is a preliminary integration of a semantic search engine that seeks to provide specific answers to questions using information from Wikipedia articles. The engine is still in early stage development and has been designed to foster community involvement to help improve the search service and interface over the development period.

Users can improve the accuracy of the AskWiki engine via the categorization feedback mechanism. Users can categorize each AskWiki Answer as an article deemed either Correct, Incorrect or Uncertain. This user feedback is processed by AskWiki to improve the search capabilities and accuracy of the AskWiki engine.

Members of the AskWiki Community are encouraged to expand upon correct answer articles and correct the incorrect or uncertain ones, re-categorizing the articles as they are updated. These efforts are tied directly into the AskWiki engine as well.

The goal of pairing AskWiki’s semantic search technology with the efforts of the AskWiki Community, is to in-time create a unique information access engine that can provide the answer to any question.

Answer: The carrot gets its characteristic orange colour from ß-carotene, which on consumption by humans is metabolised into vitamin A. Massive overconsumption of carrots can cause hypercarotenemia, a condition in which the skin turns orange (although this is superior to overdose effects of vitamin A, which can cause liver damage).
