Help build the next generation of AI-driven dialog systems

Introducing the Sentence Selection Track of DSTC8

Artificial Intelligence (AI)-driven dialog assistants are used in our day-to-day routines such as checking weather, finding restaurants, making calls and many more. In an enterprise setting, these assistants are highly useful in customer support scenarios, where they help reduce organizational costs and provide fast and accurate help to users.

However, many AI-driven dialog assistants today rely heavily approaches that are explicitly programmed by dialog designers. A key need for scientific advancement is the development of algorithms that can learn goal-oriented dialog interactions effectively from human-to-human chatlogs, while grounding them on relevant external information sources. IBM Research AI and the University of Michigan are spearheading this research direction by organizing a public competition to inspire and evaluate novel approaches that will lead to the next generation of AI-driven dialog systems.

The competition, called NOESIS II: Predicting Responses, Identifying Success, and Managing Complexity in Task-Oriented Dialog, is offered in Track 2 of Dialog Systems Technology Challenge 8 (DSTC 8). The competition is now open, with submissions due by October 6. The winners will be announced on October 20, and the participants will be invited to present their work at a workshop that will be held at a top conference to be named later. Top participants will also be invited to submit their work to a special issue of the Computer Speech and Language (CS&L) journal.

The competition is building on the success of DSTC 7 Track 1 which IBM Research AI and University of Michigan organized last year. More than 20 academic and industrial teams participated, worldwide. This year we provide extensions to the task by incorporating new elements that are vital for the creation of deployable task-oriented dialog systems.

Datasets

This challenge is offered with two goal-oriented dialog datasets:

A. Ubuntu dataset

The dataset consists of multi-party conversations extracted from the Ubuntu Internet Relay Chat (IRC) channel. A typical dialog starts with a question that was asked by participant_1. Then other participants respond with either an answer or follow-up questions that then lead to a back-and-forth conversation. Relevant external information in the form of Linux manual pages and Ubuntu discussion forums is also provided.

An example conversation from the dataset is shown below.

ubuntu dataset

B. Advising dataset

This dataset contains two party dialogs that simulate a discussion between a student and an academic advisor. The purpose of the dialogs is to guide the student to pick courses that fit not only their curriculum, but also personal preferences about time, difficulty, areas of interest, etc. These conversations were collected by having students at the University of Michigan act in the two roles using provided personas. Structured information in the form of a database of course information will be provided, as well as the personas. The data also includes paraphrases of the sentences and of the target responses.

An example conversation from the dataset is shown below.

Subtasks

This challenge is offered with four subtasks. A participant may participate in one, more than one, or all the subtasks. The primary task, given a dialog context, is to select the next turn in the conversation from a given set of candidate utterances.

subtasks

The following table shows the full set of subtasks; [x] indicates that the subtask is evaluated on the marked dataset.

Subtask number Description Ubuntu Advising
1 Given the disentangled conversation, select the next utterance from a candidate pool of 100 which might not contain the correct next utterance [x] [x]
2 Given a section of the IRC channel, select the next utterance from a candidate pool of 100 which might not contain the correct next utterance [x]
3 Given a conversation, predict where in the conversation the problem is solved (if at all). [x]
4 Given a section of the IRC channel, identify a set of conversations contained within that section [x]
