Stanford’s AI research discusses ways to trace back and retrieve the source of a query.

In a recent study, researchers addressed an inherent shortcoming of current online content portals that allow users to ask questions to improve comprehension, especially in learning environments such as lectures. Traditional information retrieval (IR) systems are great at answering these kinds of user questions, but they aren’t very good at helping content providers, such as instructors, pinpoint the exact piece of material that prompted the question in the first place. This creates a new task called backtracking to obtain the text segment that is most likely the source of the user’s query.

We formulate the backtracking task using three real-world domains, each covering different aspects of communication enhancement and content distribution. First, the purpose of the ‘lecture’ area is to find the source of students’ uncertainty. Second, understanding the cause of readers’ curiosity is the main goal of the ‘article’ area. Finally, the goal of the ‘Conversation’ area is to understand the reasons for the user’s reaction. These areas illustrate a variety of situations where backtracking can help improve content creation and understand the linguistic signals that influence user inquiries.

A zero-shot evaluation was conducted to evaluate the effectiveness of several language modeling and information retrieval strategies, such as the ChatGPT model, re-ranking, dual encoder, and likelihood-based algorithms. It is well known that traditional information retrieval systems can respond to explicit user query content by obtaining semantically related information. However, we often overlook the important context that links a user’s inquiry to a specific piece of content.

The evaluation results show that there is still a lot of room for improvement in backtracking, which requires establishing new search strategies. This means that existing systems cannot capture the causally important context that links specific pieces of information to user searches. The standards set in this study serve as a basis for improving search systems for future backtracking.

These improved systems can fill this gap and improve content creation, successfully identifying linguistic factors that influence user inquiries, thereby enabling more complex and personalized content delivery. The ultimate goal is to reduce the knowledge gap between user inquiries and material segments, promoting a more thorough understanding and improved communication process.

The team summarized their key contributions as follows:

1. A new task, called backtracking, was presented to find the section of the corpus most likely to have triggered the user’s query. To improve content quality and relevance, this meets the needs of content creators who want to improve their material in response to audience questions.

2. Benchmarks were created that formalize the importance of backtracking in three different contexts. Finding the source of readers’ curiosity in news items, finding the causes of student misunderstandings in lectures, and finding users’ emotional triggers in discussions. This thorough benchmark demonstrates how our work can be applied to a variety of content interaction settings.

3. In this study, we evaluated several well-known retrieval systems, including pre-trained language models and likelihood-based techniques using biencoder and re-ranking frameworks. Examining these systems for their ability to infer causal relationships between user searches and content segments is an important first step toward understanding the utility of backtracking.

4. The use of search techniques in backtracking operations has shown that they currently have certain limitations. These results highlight the difficulties inherent in backtracking and highlight the need for search algorithms that more accurately capture causal relationships between queries and information.
