21 21 Greyhound Data Extraction Grayhound data was gathered from The Web site links to: –GreyMatter –TrackInfo The race and odds data was parsed into a SQL Server database; then the data was sent to the AZGreyhound system for prediction.

22 22 Example code public void RacePrograms() throws Exception {... String URL1 = "http://www.trackinfo.com/trakdocs/hound/"; String URL2 = "/Rpages";... OpenConnection2(); try { TrackAbbrev = rSet.getString("TrackAbbrev"); String URL = URL1 + TrackAbbrev + URL2; Feed = web.Scraper(URL, 1);... NumItems = web.NumItems(Feed, "~icons/html.gif"); for(int y = 1; y <= NumItems; y++) { Feed = Feed.substring(Feed.indexOf("~icons/html.gif")); FileName = web.ExtractText(Feed, " "); Feed = Feed.substring(Feed.indexOf("", " "); FileContents = web.Scraper(URL + "/" + FileName, 1); FileContents = FileContents.replaceAll("'", "-"); db.Insert2DBProgram(FileName, FileDate, FileContents); } } CloseConnection2(); } catch(SQLException e) { System.out.println(e); } } This method picks up the overall race information and puts it in the database Data parsing URL Parsing out each data field Insert into DB
