Abstract: While the field of NL2SQL has made significant advancements in translating natural language instructions into executable SQL scripts for data querying and processing, achieving full automation within the broader data science pipeline – encompassing data querying, analysis, visualization, and reporting – remains a complex challenge. This study introduces SageCopilot, an advanced, industry-grade system system that automates the data science pipeline by integrating Large Language Models (LLMs), Autonomous Agents (AutoAgents), and Language User Interfaces (LUIs). Specifically, SageCopilot incorporates a two-phase design: an online component refining users’ inputs into executable scripts through In-Context Learning (ICL) and running the scripts for results reporting & visualization, and an offline preparing demonstrations requested by ICL in the online phase. A list of trending strategies such as Chain-of-Thought and prompt-tuning have been used to augment SageCopilot for enhanced performance. Through rigorous testing and comparative analysis against prompt-based solutions, SageCopilot has been empirically validated to achieve superior end-to-end performance in generating or executing scripts and offering results with visualization, backed by real-world datasets. Our in-depth ablation studies highlight the individual contributions of various components and strategies used by SageCopilot to the end-to-end correctness for data sciences.

In recent years, social media platforms have become indispensable tools in shaping public discourse. With their ability to facilitate instant communication and reach massive audiences, these platforms have revolutionized the way information is disseminated and opinions are formed. However, as their influence has grown, so have concerns about the effects they have on society.
The topic of this article is the impact of social media echo chambers on public discourse and the consequential polarization of society. An echo chamber is a phenomenon in which individuals are exposed only to like-minded opinions and ideas, reinforcing their existing beliefs and values. This perpetuates a cycle of confirmation bias, further dividing individuals into entrenched camps of ideology.
This issue is not new; history is replete with instances of ideological echo chambers, which have played a significant role in exacerbating societal divisions. In the political arena, one can look back to ancient Greek city-states, where public opinion was shaped by orators amidst the backdrop of the agora. Similarly, the rise of print media in the 18th and 19th centuries led to the proliferation of partisan newspapers that catered exclusively to specific political factions, effectively entrenching existing biases.
However, the advent of social media has intensified the echo chamber effect. These platforms are designed to personalize and curate content based on users’ preferences and habits. Algorithms feed individuals with content aligned with their existing beliefs, leading to a lack of exposure to diverse perspectives and opinions. This poses a significant challenge to healthy public discourse and the exchange of ideas.
Contemporary events have highlighted the urgency of addressing the issue of echo chambers on social media. The 2016 United States presidential election and the subsequent Brexit vote in the United Kingdom showcased how echo chambers can influence public opinion and contribute to the widening political divide. The proliferation of misinformation and conspiracy theories on social media that followed these events further underscored the dangers of echo chambers.
Recognizing this problem, scholars and experts have been studying echo chambers and proposing solutions to mitigate their impact. Understanding the mechanisms that underpin echo chambers and their repercussions is crucial in finding measures to counteract their negative effects and promote a more inclusive and informed public discourse.
Through this article, we will delve into the world of social media echo chambers, exploring their historical context and contemporary ramifications. We will examine the development of echo chambers through the lens of past and present, highlighting potential strategies to combat the polarization they engender.
