  19. Case Study: AZGreyhound System By Rob Schumaker

AZGreyhound System Design • AZGreyhound System Greyhound Data AZGreyhound DB Odds Data Model Building Training / Testing Race Data Prediction Betting Engine Metrics Traditional Straight Bets Box Bets Accuracy Win Exacta Quiniela Payout Place Trifecta Trifecta Efficiency Show Superfecta Superfecta

  21. Greyhound Data Extraction • Grayhound data was gathered from www.trackinfo.com. The Web site links to: • GreyMatter http://66.236.122.233:8080/tracklink/ • TrackInfo http://www.trackinfo.com/index2.html • The race and odds data was parsed into a SQL Server database; then the data was sent to the AZGreyhound system for prediction.

  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, "<A HREF=\"", "\">"); Feed = Feed.substring(Feed.indexOf("<A HREF=")); FileDate = web.ExtractText(Feed, "NOWRAP>", "</TD>"); 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
