Dataset Card Creation Guide

Dataset Summary

Our goal is to build systems that collaborate with people by exchanging information through natural language and reasoning over structured knowledge base. In the MutualFriend task, two agents, A and B, each have a private knowledge base, which contains a list of friends with multiple attributes (e.g., name, school, major, etc.). The agents must chat with each other to find their unique mutual friend.

Supported Tasks and Leaderboards

We consider two agents, each with a private knowledge base of items, who must communicate their knowlege to achieve a common goal. Specifically, we designed the MutualFriends task (see the figure below). Each agent has a list of friends with attributes like school, major etc. They must chat with each other to find the unique mutual friend.

Data Fields

  • uuid: example id.
  • scenario_uuid: scenario id.
  • scenario_alphas: scenario alphas.
  • scenario_attributes: all the attributes considered in the scenario. The dictionaries are liniearized: to reconstruct the dictionary of attribute i-th, one should extract the i-th elements of unique, value_type and name.
    • unique: bool.
    • value_type: code/type of the attribute.
    • name: name of the attribute.
  • scenario_kbs: descriptions of the persons present in the two users' databases. List of two (one for each user in the dialogue). scenario_kbs[i] is a list of persons. Each person is represented as two lists (one for attribute names and the other for attribute values). The j-th element of attribute names corresponds to the j-th element of attribute values (linearized dictionary).
  • agents: the two users engaged in the dialogue.
  • outcome_reward: reward of the present dialogue.
  • events: dictionary describing the dialogue. The j-th element of each sub-element of the dictionary describes the turn along the axis of the sub-element.
    • actions: type of turn (either message or select).
    • agents: who is talking? Agent 1 or 0?
    • data_messages: the string exchanged if action==message. Otherwise, empty string.
    • data_selects: selection of the user if action==select. Otherwise, empty selection/dictionary.
    • start_times: always -1 in these data.
    • times: sending time.

Data Splits

There are 8967 dialogues for training, 1083 for validation and 1107 for testing.

    abstract = "We study a \textit{symmetric collaborative dialogue} setting in which two agents, each with private knowledge, must strategically communicate to achieve a common goal. The open-ended dialogue state in this setting poses new challenges for existing dialogue systems. We collected a dataset of 11K human-human dialogues, which exhibits interesting lexical, semantic, and strategic elements. To model both structured knowledge and unstructured language, we propose a neural model with dynamic knowledge graph embeddings that evolve as the dialogue progresses. Automatic and human evaluations show that our model is both more effective at achieving the goal and more human-like than baseline neural and rule-based models.",
