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.
21
Example code
public void RacePrograms() throws Exception {
... ...
String URL1 = "http://www.trackinfo.com/trakdocs/hound/";
This method picks up the
String URL2 = "/Rpages";
... ...
overall race information
OpenConnection2();
try {
... ...
Data parsing URL
TrackAbbrev = rSet.getString("TrackAbbrev");
and puts it in the database
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=\"", "\">");
Parsing out each
data field
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();
}
Insert into DB
catch(SQLException e) {
System.out.println(e); }
}
