Managing Conversational Interfaces with Talkamatic

Talkamatic is a system designed to manage conversations for various applications. This tool helps in developing chatbots and other conversational interfaces that can interact with users in a more natural and flexible way. The focus of Talkamatic is on improving how dialogues can be managed, especially when it comes to negotiating and refining user inquiries. This article will break down how Talkamatic works and its key features, especially in the context of searching for information, such as phone numbers.

#What is Negotiative Dialogue?

Negotiative dialogue refers to conversations where participants exchange information to reach a mutual understanding or to find a specific result. In many cases, this involves asking questions about alternatives or refining a search based on user feedback. For example, if you are trying to find a specific phone number, you might start by asking for a person's name and then narrow it down by asking for additional information like their location or age.

#The Talkamatic Dialogue Manager's Approach

Talkamatic aims to develop a dialogue manager based on reliable engineering principles. This means it is designed to separate general dialogue knowledge from specific domain knowledge. For developers, this separation allows them to focus on the specific details of a domain, like phone directories, while the dialogue manager takes care of how to conduct the overall conversation.

#Structure of the Dialogue Manager

The architecture of Talkamatic sets up a clear distinction between two types of knowledge:

1. General Dialogue Knowledge: This includes how to manage conversations, like understanding different ways a user might ask questions and how to respond effectively.

2. Domain-specific Knowledge: This covers information related to the specific area of focus, like names, addresses, and phone numbers in a phone directory.

By following this structure, developers can create applications without needing to change the core dialogue manager, which simplifies the development process.

#Features of Negotiative Dialogue in Talkamatic

Talkamatic has started to implement features that support negotiative dialogue. Here are some of the main features that have been worked on:

#Asking About Alternatives

One of the crucial aspects of a good conversational system is its ability to handle questions about alternatives. When users are not sure of the exact answer, they might want to compare different options. For instance, if someone asks for the phone number of a person with a common name, the system can provide several matches and inquire further details, like the age or street name of the person being searched for.

An example interaction could look like this:

• User asks: "I need the number for Anna Andersson in Gothenburg."
• System replies: "There are three people matching your description. How old are they?"

This method allows the user to refine their request dynamically, based on the information provided.

#Knowledge Precondition Questions

Another interesting find during the development was the use of Knowledge Precondition Questions (KPQs). These questions help the system determine whether the user has the necessary information to answer a follow-up question. For example, rather than directly asking for a street name, the system might ask, "Do you know the street name?".

This type of questioning makes it easier for users to engage in the conversation. If they do not know the answer, they can simply say "no", and the system can adjust its questions accordingly. This way, conversations can flow more naturally and adapt to the user's knowledge level.

#Modifying Search Criteria

Users often want to change their search criteria after receiving some initial information. Talkamatic allows users to modify their requests easily. For example, after getting a phone number for one person, they could ask for another based on a different age or characteristic.

Here’s an example:

• System says: "There are three people matching your description. Do you know the street name?"
• User replies: "I think she is 42 years old."
• System responds: "The phone number is NNN-NNN NN NN."
• User then asks: "What is the phone number for the one who is 31 years old, just in case I'm wrong?"
• System answers with the corresponding number.

This flexibility in modifying search parameters allows users to refine their inquiries without starting over.

#The Implementation of Dialogues in the Phone Directory Domain

To implement features for negotiations in a phone directory context, a dialogue plan is established. This plan guides the system on how to interact with users, ensuring that the questions posed lead to obtaining the needed information effectively.

#Future Directions for Talkamatic

As Talkamatic continues to develop, future work is planned to fully support negotiative dialogue features. This means making the system even better at handling complex conversations and refining user requests. The goal is to create a tool that can adapt to various domains while maintaining a natural and efficient dialogue flow.

#Conclusion

The advancements in the Talkamatic Dialogue Manager show a significant movement toward improving conversational interfaces. By focusing on features that enhance negotiative dialogue, Talkamatic is working to create a system that not only understands user requests but also helps users clarify and refine their inquiries effectively. This can lead to more efficient and satisfying interactions between users and conversational agents.

As technology progresses, systems like Talkamatic will likely become a standard in creating user-friendly interfaces that can manage complex conversations in an intuitive way. The goal is to make interactions with machines as seamless as conversations with other people.
