What is the reason for the client not knowing the answer?

For instance, if the service provider informs the client that there are (not) available rooms, the client does not need to know the reason determining the answer: the only relevant fact is the performed speech act.

What is the meaning of the interaction turns?

The interaction turns can be modeled as generic conversational activities, by omitting the performed speech act (Inform, Query-if, etc.).

Enabling conversations with web services

TL;DR: The model supports the consumer in the management of a conversation which respects the business logic of the service without imposing the explicit management of the conversational context.

Abstract: The emerging standards for the publication of Web Services enable the invocation of services having simple interaction protocols, but they fail to support complex e-business interactions, where the peers exchange several messages. In order to extend the classes of services which can be invoked by the consumers, we propose a conversational model supporting the management of complex interactions between clients and Web Services. Our model supports the consumer in the management of a conversation which respects the business logic of the service without imposing the explicit management of the conversational context.

Most frequently asked questions

1. What have the authors contributed in "Enabling conversations with web services" ?

In order to extend the classes of services which can be invoked by the consumers, the authors propose a conversational model supporting the management of complex interactions between clients and Web Services.

2. What are the types of messages that are used in the WSDL?

In particular, there are input and output messages, where input messages represent the messages to be received by the service provider and output messages represent those that the provider sends to the client.

3. What is the proposed WSFL-like specification of the conversation flow?

The proposed WSFL-like specification of the conversation flow supports the specification of services requiring complex interactions between clients and suppliers.

4. What is the interaction flow in Figure 1?

The interaction flow specified in Figure 1 is simpler than the typical (hierarchical) plans used in human-computer taskoriented dialogs (see [5]), because the authors need to model much simpler and predictable types of interaction.
