SE-PQA: Personalized Community Question Answering
Personalization in Information Retrieval is a topic studied for a long time.
Nevertheless, there is still a lack of high-quality, real-world datasets to
conduct large-scale experiments and evaluate models for personalized search.
This paper contributes to filling this gap by introducing SE-PQA (StackExchange
- Personalized Question Answering), a new curated resource to design and
evaluate personalized models related to the task of community Question
Answering (cQA). The contributed dataset includes more than 1 million queries
and 2 million answers, annotated with a rich set of features modeling the
social interactions among the users of a popular cQA platform. We describe the
characteristics of SE-PQA and detail the features associated with questions and
answers. We also provide reproducible baseline methods for the cQA task based
on the resource, including deep learning models and personalization approaches.
The results of the preliminary experiments conducted show the appropriateness
of SE-PQA to train effective cQA models; they also show that personalization
remarkably improves the effectiveness of all the methods tested. Furthermore,
we show the benefits in terms of robustness and generalization of combining
data from multiple communities for personalization purposes
Utilizing ChatGPT to Enhance Clinical Trial Enrollment
Clinical trials are a critical component of evaluating the effectiveness of
new medical interventions and driving advancements in medical research.
Therefore, timely enrollment of patients is crucial to prevent delays or
premature termination of trials. In this context, Electronic Health Records
(EHRs) have emerged as a valuable tool for identifying and enrolling eligible
participants. In this study, we propose an automated approach that leverages
ChatGPT, a large language model, to extract patient-related information from
unstructured clinical notes and generate search queries for retrieving
potentially eligible clinical trials. Our empirical evaluation, conducted on
two benchmark retrieval collections, shows improved retrieval performance
compared to existing approaches when several general-purposed and task-specific
prompts are used. Notably, ChatGPT-generated queries also outperform
human-generated queries in terms of retrieval performance. These findings
highlight the potential use of ChatGPT to enhance clinical trial enrollment
while ensuring the quality of medical service and minimizing direct risks to
patients.Comment: Under Revie
