  1. In Dialogue with the Web Torbjörn Lager, Dept. of Philosophy, Linguistics and Theory of Science University of Gothenburg

  2. The web? • The web of documents • The web of people • The web of data • The web of things

  3. Interaction with the Good Ol' Web • The web browser –a window to the web • Browsing (clicking links) • Searching (filling in forms, clicking buttons) • Interacting with a web application (all of the above plus dragging, dropping, selecting, etc.) • A direct manipulation style of interaction

  4. Dialogue (Conversation) • A form of interaction, • between at least two agents, • often, but not always, for the purpose of exchanging information. • Has the form of a (fairly rapid) exchange of (fairly short) written or spoken utterances in natural language (often supplemented by gestures)

  8. VoiceXML – a part of the Web HTML HTML browser VoiceXML Web servers VoiceXML browser(ASR, TTS, interpreter)

  9. VoiceXML example <vxml version="2.1" application="franks.xml"> <form> <block> <prompt> Thanks for calling Frank's pizza palace. </prompt> </block> <field name="phone" type="digits"> <prompt> May I have your phone number please? </prompt> </field> <field name="correct" type="boolean"> <prompt> I heard <say-as interpret-as="telephone"><value expr="phone"/></say-as>. Is this correct? </prompt> </field> <filled> <if cond="correct"> <assign name="application.phone" expr="phone"/> <submit next="db-lookup-phone.cgi" namelist="phone"/> <else/> <clear namelist="phone correct"/> </if> </filled> </form> </vxml>

  10. SRGS example <grammar tag-format="semantics/1.0" root="INIT"> <rule id="INIT" scope="public"> <one-of> <item> I would like a <ruleref uri="#size"/> <ruleref uri="#type"/> pizza with <ruleref uri="#topping"/> <tag>out.size = rules.size; out.type = rules.type; out.topping = rules.topping;</tag> </item> <item> <ruleref uri="#size"/> <tag>out.size = rules.size ;</tag> </item> ... </one-of> </rule> <rule id="size"> <one-of> <item> small </item> <item> medium </item> <item> large </item> <item> big <tag>out = 'large';</tag></item> </one-of> </rule> <rule id="type"> <one-of> <item> hand tossed </item> <item> cheese crusted </item> </one-of> </rule> </grammar>

  12. In Dialogue with the WebTomorrow?

  13. More likely (in my view) • A web of agents (human and artificial agents) • Why? • The web will never become a consistent body of knowledge • The "beliefs" of artificial agents will vary as much as the beliefs of human agents • So we will need to be in dialogue with more than one of them, and sometimes with more than one at a time • Multi-party dialogue • The web of things will be involved as well. But things are things, not agents...

  14. How? The big picture...

  15. Key Fields and Notions • Knowledge representation • Interaction management • Natural language processing • Open standards • Formal foundations • Modelling techniques and methodologies

  17. Linked Data

  18. Interaction Management • Interaction is a key notion here • The interaction between human and system (agent) • The interaction between different loosely coupled components of a single system (agent) • The interaction between one system (agent) and another • The interaction between human users of the web, mediated by a system • Handle these forms of interaction in a uniform way? • Interaction managers specified in Statecharts and SCXML

  19. Flashlight statechart

  21. Open standards • For representing information/knowledge: • RDF, RDFS, OWL, SWRL • For specifying interaction: • SCXML

  22. Flashlight Statechart in SCXML <scxml initial=“off"> <state id=“off"> <transition event=“push" target=“on"/> </state> <state id=“on"> <transition event=“push" target=“off"/> </state> </scxml>

  23. Foundations • RDF, RDFS, OWL and SWRL are based on logic • SCXML is based on the theory of state machines • states, transitions between states, triggered by events

  24. Natural Language Processing Page intentionally left blank...

  25. Modelling • Knowledge engineers • Interaction designers • (Computational) linguists
