Information Extraction from Real Estate Classifieds

Technology Demonstration

Either check Random Ad for a random ad (from a selection of 200) or check This Ad and enter an ad into the box provided. (The ad should be either plain ASCII text (with line breaks) or in a particular SGML format, which is not documented here but is used in the random examples. Note that you need to make an entered ad really look like a real estate for sale ad -- e.g., not all lower case -- or the program will simply reject it as not a real estate for sale ad.)

Random Ad
This Ad. (Enter the ad below.)

Updated 26 Mar 1998. This user interface is just for demonstration purposes and is not intended for real use. The demonstration uses a weighted random sample so that the proportion of real estate ads in the sample (about 2/3) is double that of the data in general (about 1/3 real estate for sale), but the data is otherwise randomly chosen authentic data.
