I hope that WebOnt will be used to provide information that's currently available on the WWW (and not currently available on the WWW) in such a way that I can write and/or use programs to automate tasks such as those related to business travel. I'll use that domain as a focus for this use case. I generally plan my travel before calling my human corporate travel agent. For flights, I use a copy of the United Airlines Electronic Timetable, which gets monthly (weekly since 9/11) updates in a some sort of compressed binary format (I've made several unsuccessful attempts to extract the underlying data). I like the fact that I can work with this offline (e.g. on an airplane). I'd much prefer to get it in WebOnt format so that I can apply my own preferences, link to other information about airports, etc. I have a hotel chain that I prefer. For destinations that I frequent often, I know their hotels in the area but often forget some of the details (e.g. which ones serve good hamburgers, and which room locations to avoid). For others, I look up information on their web sites. I'd like to get this information in WebOnt format, and to add my own properties for items of personal interest. I normally try to get a hotel room that has high-speed wired or wireless Internet access. Hotel web sites are very inconsistent in reporting this service. For an unfamiliar property, I generally look at the directories maintained by the major ISPs serving hotels (CAIS, STSN, Wayport, and MobileStar), none of which currently provide the information in an agent-friendly format (most use maps, page hierarchies, and/or PDF). I'd prefer to get it in WebOnt and merge it myself with my itinerary and other geographic information. When I make a reservation, my corporate travel agent emails my itinerary in a format that I consider a canonical example of the "un-Semantic Web": a PDF image of a traditional FAXed itinerary. This prints well, but is virtually impossible for a program to process. I'd prefer to get this content using WebOnt, and to have it automatically routed to a personal travel agent program. I'd like to automatically share some of my itinerary information (e.g. travel dates and arrival times) with my co-workers, but keep some of it (e.g. credit card numbers) private. After my airline ticket is booked, I generally have to call the airline directly to get an upgrade and/or better seat assignment. I prefer non-bulkhead (so I can keep my laptop under the seat in front of me) window seats. United is unable to track this preference, so I often have to make several calls. An agent would be better (and more reliable!) at this task. I now subscribe to United's Flight Paging Service, which automatically sends an email message to my pager 2 hours before my flight or whenever a delay or cancellation occurs. I'd prefer for my agent to get this information in WebOnt format so that it could automatically begin identifying alternative flights and routings when a problem arises. I also subscribe to a free service from fly.faa.gov, which sends me email messages on ground stops and delays at specified airports. Unfortunately, it's not linked to my itineraries, so I get lots of such messages while I'm not travelling. If the information was in WebOnt format, my agent could easily cross-reference it with my itineraries and identify relevant problems. While I travel, I'd like to have fast access to my itinerary using a utility like PalmDAML [1] on my PDA. When I have a substantial wait at an airport, I like to look for high-speed Internet access. I've generally had better luck searching concourses than web pages to find such services; I'd like to get such information (translated to) my preferred WebOnt ontology. I sometimes go to the American Airlines Admirals Clubs to use their high-speed MobileStar wireless Internet access points. This is usually in a different terminal, so I'd like to also get WebOnt information on gate locations and walking times. When I go to an unfamiliar city, I often try to rent a Hertz car with a NeverLost GPS. Rather than painstakingly toggling in the street names and numbers for my hotel and other destinations, I'd like to just beam the information in WebOnt format from my PDA using IR or Bluetooth. I'd also like to get additional information that's not generally now on the web: service hours for restaurants (and room service) along my travel route. For flights that get in late, for example, my agent could tell me if I need to grab a bite before leaving the airport. When I return from a trip, I have to fill-out an Excel spreadsheet for my expense report. Most of this information could come directly from my itinerary, hotel bills, and credit card receipts if they were provided in WebOnt format. I already have a DAML application [2] for reconciling my expense reports with my credit card statements and checking account. A few observations: 1) most of this information (flight schedules, travel itineraries, hotel addresses, expense reports, etc.) is not ontologically sophisticated 2) much of the information is already available in human-readable form 3) automation currently exists only in specific stovepipes such as United's new Flight Paging Service 4) even a highly-motivated geek finds it impractical to merge the existing information 5) with widespread use of WebOnt, we should be able to do most of these things pretty easily Mike [1] http://www.daml.org/PalmDAML/ [2] http://www.daml.org/2001/06/expenses/
