We have noticed that references to '9/11', 'September 11, 2001' in content we submit to opencalais is not extracted as entities.  Can someone explain why this is the case?  Are we doing something wrong?
Currently, we are using the python-calais interface.  The only arguments we supply to the analyze call are the text and content_type='TEXT/RAW'.
 
thanks in advance for your help,

The technical team asks that you send or post an example of real text and the entities you would expect. That's the best way they can respond to your query.

Here is the real text for one particular 9/11 story:

u'\r\n\r\n\r\n\r\n\r\n\r\n\r\nBrotherhood Ride 2011 will hold a send-off ceremony at 8 a.m. Saturday, Aug. 20, at North Naples Fire Station 45, at 1885 Veterans Drive.\r\nThe riders will stop at Southwest Florida International Airport later that morning to raffle two JetBlue flights.\r\nFor more information, call Jeffrey Morse at (239) 633-7098.\r\n\r\n\r\nWhen it comes to honoring his fallen brothers, North Naples firefighter Jeffrey Morse doesn\u2019t believe in small gestures.\r\n\r\nNor do the 38 other emergency service workers from across the nation who are pedaling from Naples to New York City by bicycle in the 2011 Brotherhood Ride. Their effort is a tribute to the 411 emergency service workers who died at the World Trade Center on 9/11 nearly 10 years ago.\r\n\r\nAttempting to rescue victims or put out fires, 343 New York City firefighters, 60 police officers and eight private Emergency Medical Service responders were killed when the towers fell.\r\n\r\n\u201cBefore they went in, they knew this wasn\u2019t going to be a good outcome,\u201d said Morse, who organized the ride. \u201cThey knew this was going to be a tough mission. Not one of them turned around to walk out that door. That\u2019s the kind of dedication that we want to honor.\u201d\r\n\r\nMorse \u2014 along with firefighters, police officers and EMS personnel representing departments from Southwest Florida to Massachusetts to Arizona \u2014 will set off Saturday. Each will wear red, white and blue jerseys carrying the 411 names of their fallen brothers on their backs.\r\n\r\nIn addition to honoring the 9/11 heroes, the team is using the 1,600-mile ride to raise money for the National Fallen Firefighters Foundation and the Concerns of Police Survivors, which supports the families of service workers killed on duty.\r\n\r\nThe team also is riding for Rob Morehead, an emergency medical services pilot from Louisiana. Morehead was scheduled to ride with them to New York, but was killed in a bicycling collision in Louisiana in April.\r\n\r\nMorse said the team would carry some of Morehead\u2019s cremated ashes to honor him.\r\n\r\nThis will be the fifth trip in four years for the Brotherhood Ride. Teams also have biked to Tampa, Charleston, S.C. and Houston, Texas, in honor of firefighters and police officers killed on duty. In 2009, they biked for Fort Myers police officer Andrew Widman, who was shot to death on duty in 2008.\r\n\r\nMost of the participants, including those from Southwest Florida, use vacation time to go on the trek. It\u2019s doubtful the riders, many in their 40s and 50s, will come back physically refreshed.\r\n\r\nFor this ride \u2014 the longest by far \u2014 the team will ride for 22 grueling days, averaging more than 70 miles per day, weathering whatever heat and rain come its way. Rather than a direct line to New York, the ride will take a somewhat circuitous route to attend scheduled events along the way.\r\n\r\n\u201cIt\u2019s definitely a labor of love,\u201d said Morse, 48.\r\n\r\nEvery 20 miles or so, the team will stop at police and fire stations to mingle with fellow emergency services staff members and pass around the bucket for donations. A 40th rider will join them in Charleston, S.C.\r\n\r\nInstead of hotels, they will sleep on air mattresses at Elk\u2019s Lodge spots.\r\n\r\nPolice or fire agencies in every town and county they pass through have promised to escort the team. That\u2019s in addition to a 15-person support staff following in trucks and SUVs.\r\n\r\n\r\n\r\n\r\nParticipants from Southwest Florida\r\nNorth Naples Fire Control and Rescue District: Jack Bills; Luciano DeAndrade; Nick Ford; Paul Manguso; Jeff Morse; Jerry Sandlin; Jeff VanNortwick\r\nNaples Police Department: Buddy Bonollo\r\nLehigh Acres Fire Department: Scott Berggren\r\nCollier County Sheriff\u2019s Office: Bruce Cordivari; Dan McDonald\r\nGolden Gate Fire Control and Rescue District: Jesus Padilla; Scott Wilson\r\nFort Myers Police Department: Keith Curr; Donald Weathers\r\nEstero Fire Control and Rescue District: Jerry Krohnfeldt; Scott Labree\r\nEast Naples Fire Control and Rescue District: Dave Perez\r\nCollier County Fire Code Office: Bob Salvaggio\r\n\r\n\r\nThe ride will be physically and emotionally taxing, said Bob Branch, a district chief for the Houston Fire Department, who has participated each year.\r\n\r\n\u201cWe just work through it,\u201d he said. \u201cWe support each other.\u201d\r\n\r\nOnce in New York, the 40 riders will meet with New York City firefighters near ground zero. They will stay through Sept. 11 to attend 9/11 ceremonies before flying back to Fort Myers the next day with tickets donated by JetBlue.\r\n\r\n \u25a0 \u25a0 \u25a0 \r\n\r\nMorse and other North Naples firefighters founded the benefit in 2008 as a way to honor nine Charleston firefighters killed on duty in 2007. That big gesture became an annual way to honor fallen firefighters and police officers on the anniversary of their deaths.\r\n\r\n\u201cWhether one year or 10 years later, their memories and sacrifices have not been forgotten,\u201d Branch said.\r\n\r\nThe strenuous bike rides are about showing effort to the families of the fallen, Morse said, \u201cas opposed to writing a check.\u201d\r\n\r\n\u201cIt\u2019s easy to raise money,\u201d he said. \u201cIt\u2019s a little more difficult to do something like this.\u201d\r\n\r\nThe rides also draw the attention of the public and media in the communities traveled through, which helps fundraising. By Morse\u2019s estimate, the team has raised $68,000 in four years for the families of fallen police officers and firefighters \u2014 most of that comes on the road.\r\n\r\nMorse downplays the notion that this 10th anniversary 9/11 ride is more significant than previous rides.\r\n\r\n\u201cI think it\u2019s really important to remember what happened on 9/11,\u201d he said. \u201cBut this is no more important than the others.\u201d\r\n\r\nHowever, this ride has special significance for retired New York City firefighter Dan Rowan, who responded to the World Trade Center after the towers collapsed on 9/11.\r\n\r\nWhile all 40 riders will bicycle for the 411 names on their backs, Rowan said, 10 of those names will be on his mind.\r\n\r\nRowan, 55, was with Ladder 9 in Engine 33 Fire House on that day. Ten men from his company died after the towers fell.\r\n\r\nRowan\u2019s toughest days were the ones following 9/11, he recalls. The hardest part, he said, was delivering the eulogies for his brothers while trying to fight back tears.\r\n\r\n\u201cEvery day, I live it,\u201d Rowan said.\r\n\r\nRowan, now a police officer in Marana, Ariz., keeps his firefighter bunker gear from 9/11 in his patrol car to help him remember.\r\n\r\nStill, Rowan expects the memories to flood back even stronger when he rolls into Manhattan at the end of the journey.\r\n\r\n\u201cIt means a lot to me to ride,\u201d he said. \u201cI\u2019m looking forward to it.\u201d\r\n\r\n * * * * * * * * * * \r\n\r\nDonations for the Brotherhood Ride can be made at the website www.brotherhoodride.com or can be mailed to Brotherhood Ride, P.O. Box 110862, Naples, Fla., 34108. Follow the progress of the ride at blogs.naplesnews.com/brotherhoodride.\r\n\r\n'

We were expecting '9/11' or 'September 11' to be extracted.

Again, we are using the python bridge and here is the call we make:

calais = Calais('s3xufuk5v5qy7kjtbuyz8f62', submitter='ewscripps')result = calais_obj.analyze(raw_text, content_type='TEXT/RAW')

where Calais is calais.Calais

I noticed in the documentation that entities are separated from events/facts. It does not appear that events/facts are being extracted. Maybe '9/11' would be an event or fact? But how do i access the extracted event/fact elements?

Thanks again for your help.

Unfortunately Open Calais has no Entity with specification to extract '9/11' from text.

I never seem to get events/facts back in my result from the analyze method. How do i retrieve extracted events/facts from the analyzed result?

thank you for your help,
