2. Background
– Semantic Technologies – technological support for encoding
meaning in a form computers can understand and
manipulate – are maturing and increasing in usage
– Computational encodings of meaning can be used to help
integrate, validate, filter,…. Essentially to make smarter,
more context-aware applications
– This can provide competitive advantage in todays
increasingly networked and competitive environments
– Motivating Vision
– Semantic Web intro through examples: Ontologies, Mobile
Advisor, Linked Data
– Discussion
Delivered by semantic web guru and road warrior…

4. Scenario 1: Real
Time Travel Change
Change and the disrupted traveler
• Weather or mechanical issues mean leaving a traveler
stranded at an intermediate destination
• Default coping strategy is not desirable to traveler (i.e., local
intermediate hotel and transportation the next day)
• Transportation to an alternative airport somewhat near
desired destination along with confirmed new last one way
leg (e.g. one way car rental available at the arrival time)
would be vastly superior
5. Scenario 1 Information
Requirements
• Location:
– Current airport
– Destination airport (and/or final destination)
– Airports within x hour driving radius
• Schedules
– Flights to alternative airports in correct time period
• Connections to other ecosystem partners
– Other transportation options to final destination (train, bus, car with
a local starting point)
– Other transportation options from alternative destination to final
destination
– Critical parameters: availability, one-way rental, operating hours for
pickup/drop off
Much of this is freely available and with passenger data
including loyalty memberships, this could be connected easily
6. Scenario 2: Advance
Travel purchase
• Known departure and destination airport
• With air loyalty program information, could offer air approp. options
(confirmed upgrades, lay back seat, reclining seat, discounted
business vs. full fare economy….)
• With destination address and hotel loyalty programs, could offer hotel
rooms near address with loyalty brands (including benefits of loyalty
program customer tier – e.g., upgrades, discounts, etc.)
• With car loyalty programs, could offer car options
• If additional tickets purchased, could offer larger car
• If with spouse (often in air systems), could offer more leisure
packages
• If connected to restaurant booking (foursquare, open table, …) or
preferences, could offer dinner bookings
• If connected to online calendar (e.g., Google), could pick up
conference information
7. Semantic Web: Introduction
through examples
• Semantic Sommelier: Mobile Context Aware Semantic Wine
Advisor
• SemantAqua: Semantically-Aware information aggregator &
visualizer
There are many more….
• PopSciGrid – aimed at Preventable Cancers
• DARPA Personal Assistant that Learns -> SIRI
• IARPA Analyst Workbench -> Watson
• Home Theatre Advisor Configurator
8. Notes
• Examples are from other domains because travel domains
have not been built out to the same level. Most travel
examples are at a syntactic level (or light weight semantics)
such as aggregators or natural language interfaces with
some semantics (such as Siri) but less about actually
“thinking” or acting as a personal assistant and more about
finding information
• One take home message after these examples will be that
the time is now to build the same kind of applications
described in the next few slides in travel…. Creating
customized semantic concierges
9. Semantically-enabled advisors
utilize:
• Ontologies
• Reasoning
• Social
• Mobile
• Provenance
• Context

10. Semantic
Sommelier
Previous versions used ontologies
to infer descriptions of wines for
meals and query for wines
New version uses
Context: GPS location, local
restaurants and wine lists, user
preferences
Social input: Twitter, Facebook, Wiki,
mobile, …
Source variability in quality,
contradictions exist,
Maintenance is an issue… however
new models emerging
11. SemantEco/SemantAqua
• Enable/Empower citizens &
scientists to explore pollution
sites, facilities, regulations,
and health impacts along with 5 4
provenance. 2 3
• Demonstrates semantic
monitoring possibilities.
• Map presentation of analysis 1
• Explanations and http://was.tw.rpi.edu/swqp/map.html and
http://aquarius.tw.rpi.edu/projects/semantaqua
Provenance available
1. Map view of analyzed results
2. Explanation of pollution
3. Possible health effect of contaminant (from EPA)
4. Filtering by facet to select type of data
5. Link for reporting problems
13. Why did I present wine and
water applications?
• Wine advisor shows semantic technology in action making
actionable recommendations
• Water application shows a “typical” semantic integration web
3.0 application
• Both of these styles are needed for a semantic concierge and
these features are realizable today
• Next – they depend on
– Semantic web stack
– Data availability – linked data cloud is growing
– Ontologies
– Semantic methodologies
– Understandable and Actionable applications

20. Back to Travel
Existing mobile and web site applications allow online
browsing, status checks, mobile access, with purchase
options
However they often
• Are not well connected into travel ecosystems
• Do not use sensor-based context – e.g., GPS
• Are not connected to user context – previous queries, and
actions, google calendar, loyalty connections, status
levels etc.
22. • Semantic Technologies: ready for use
•
The Semantic Web
Tools & tutorials available; deep apps
enables…
future planning may benefit from
consultants
• • New models of intelligent services
Context-aware, semantic
apps are the future
• E-commerce solutions
• M-commerce
• Web assistants
• …
New forms of web assistants/agents that act on a
human’s behalf requiring less from humans
and their communication devices…
