Information extraction (IE) is a type of information retrieval whose goal is to automatically extract structured information from unstructured machine-readable documents, generally human language texts by means of natural language processing (NLP). Due to the difficulty of the problem, current approaches to IE focus on narrowly restricted domains. An example is the extraction from news wire reports of corporate mergers, such as denoted by the formal relation:
from an online news sentence such as:
A broad goal of IE is to allow computation to be done on the previously unstructured data. A more specific goal is to allow logical reasoning to draw inferences based on the logical content of the input data. Structured data is semantically well-defined data from a chosen target domain, interpreted with respect to category and context. From Wikipedia under the

Asked by kelly - Fri Jun 19 11:59:37 2009 - - 3 Answers - 0 Comments A. look it up on wikipedia. There's lots of information there, and there are more than likely links to papers that will help you. If you're talking about extracting metals from metal oxide ores, then that's not too hard. Most often the way it is done is by using steps of redox reactions. Often the metal content of an iron ore is determined by a redox titration using a reagent called permanganate (MnO4^-). From there they can determine how much iron is in a sample of ore and therefore decide whether or not mining there will be worthwhile. Often Aluminum ores are processed using Fluorine extracted from a mineral called Fluorite (CaF2) and using strong redox reactions to remove oxygen and other undesirable things.

Q. I've recently got my teeth extracted, one thats considered a back tooth on the bottom, but closest to the front was removed due to it still being a baby tooth with no adult tooth underneath. I woke up the next morning with something strange and red, i spit it out, and it turned out to be a blood clot of some sorts. I've been reading some information about teeth extraction and dry sockets, and Apparently from the information that i've read it says that I should not remove those blood clots and thats the cause of dry sockets. Althought, the information was not totally reliable and i'll admit, i skim through things. My question is should I remove blood clots or any thing developing where my tooth was extracted? And how can I prevent dry… [cont.] Asked by Dan L - Tue Mar 31 14:38:35 2009 - - 1 Answers - 0 Comments A. Dry sockets happen when there is insufficient blood the in the socket to initiate the healing process. Smoking can be one good cause to lead to a dry socket, especially if its a tooth in the lower jaw. Best is to avoid smoking and meet your dentist for a check up. Dr. Jagdish T.
