Dataset Summary

We study negotiation dialogues where two agents, a buyer and a seller, negotiate over the price of an time for sale. We collected a dataset of more than 6K negotiation dialogues over multiple categories of products scraped from Craigslist. Our goal is to develop an agent that negotiates with humans through such conversations. The challenge is to handle both the negotiation strategy and the rich language for bargaining. To this end, we develop a modular framework which separates strategy learning from language generation. Specifically, we learn strategies in a coarse dialogue act space and instantiate that into utterances conditioned on dialogue history.

Data Fields

  • agent_info: Information about each of the agents taking part in the dialogue
    • Bottomline: TBD
    • Role: Whether the agent is buyer or seller
    • Target: Target price that the buyer/seller wants to hit in the negotiation
  • agent_turn: Agent taking the current turn in the dialogue (int index corresponding to Role above)
  • dialogue_acts: Rules-based information about the strategy of each agent for each turn
    • intent: The intent of the agent at the particular turn (offer, accept, etc.)
    • price: The current item price associated with the intent and turn in the bargaining process. Default value for missing: (-1)
  • items: Information about the item the agents are bargaining for. Note that there is an elembet for each of the fields below for each agent
    • Category: Category of the item
    • Description: Description(s) of the item
    • Images: (comma delimited) strings of image names of the item
    • Price: Price(s) of the item. Default value for missing: (-1)
    • Title: Title(s) of the item
  • utterance: Utterance for each turn in the dialogue, corresponding to the agent in agent_turns. The utterance may be an empty string ('') for some turns if multiple dialogue acts take place after an utterance (e.g. there are often multiple dialogue acts associated with the closing of the bargaining process after all utterances have completed to describe the conclusion of the bargaining).

Data Splits

This dataset contains three splits, train, validation and test. Note that test is not provided with dialogue_acts information as described above. To ensure schema consistency across dataset splits, the dialogue_acts field in the test split is populated with the default values: {"price": -1.0, "intent": ""}

The counts of examples in each split are as follows:

| | Train | Valid | Test | | Input Examples | 5247 | 597 | 838 | | Average Dialogue Length | 9.14 | 9.17 | 9.24 |

Dataset Creation

From the source paper for this dataset:

To generate the negotiation scenarios, we scraped postings on sfbay.craigslist.org from the 6 most popular categories (housing, furniture, cars, bikes, phones, and electronics). Each posting produces three scenarios with the buyer’s target prices at 0.5x, 0.7x and 0.9x of the listing price. Statistics of the scenarios are shown in Table 2. We collected 6682 human-human dialogues on AMT using the interface shown in Appendix A Figure 2. The dataset statistics in Table 3 show that CRAIGSLISTBARGAIN has longer dialogues and more diverse utterances compared to prior datasets. Furthermore, workers were encouraged to embellish the item and negotiate side offers such as free delivery or pick-up. This highly relatable scenario leads to richer dialogues such as the one shown in Table 1. We also observed various persuasion techniques listed in Table 4 such as embellishment,
