Beyond RAG: LLM Tool Calling Ushers in a New Era for Semantic Search

Beyond RAG: LLM Tool Calling Ushers in a New Era for Semantic Search

This article explores methods for implementing semantic search, particularly using LLMs for vector embedding search. While directly embedding user search terms and documents sometimes yields suboptimal results, new techniques like Nomic Embed Text v2 improve embedding methods, bringing questions and answers closer together in vector space. Furthermore, LLMs can synthesize potential answers, then use those embeddings to search for relevant documents. The article also introduces LLM-based Retrieval-Augmented Generation (RAG) systems, emphasizing that RAG doesn't rely on vector embeddings and can be combined with keyword search or hybrid search systems. The author argues that despite the emergence of long-context models, RAG won't disappear because the amount of data will always exceed model context capacity. The author favors the LLM tool-calling approach, exemplified by o3 and o4-mini, believing it's more effective than traditional RAG (single retrieval followed by direct answering).

Sortition: A Return to Ancient Athenian Democracy?

This article explores the potential of replacing elections with sortition (random selection) of political representatives. Ancient Athenian democracy utilized sortition for council and jury selection, embodying the principle of rotational governance. Today, facing issues of underrepresentation in electoral systems, scholars and activists propose reviving sortition to enhance decision-making's representativeness and inclusivity. The article analyzes the experiences of citizen assemblies in Canada, Ireland, and elsewhere, acknowledging sortition's potential to improve decision quality and representation while highlighting challenges in accountability and public engagement. Ultimately, the article argues that sortition isn't a simple replacement for elections but should complement them, coupled with effective public communication mechanisms, to better achieve democratic goals.

What Exactly Is a Second?

2025-01-01

This article delves into the evolving definition of a second. Initially defined as 1/86400th of a day, the slowing rotation of the Earth rendered this definition imprecise. In 1967, the second was redefined as the duration of 9,192,631,770 periods of the radiation corresponding to the transition between two hyperfine levels of the ground state of the cesium-133 atom. Cesium was chosen for its ease of isolation and purification, while the specific number of periods ensured backward compatibility with the length of the tropical year in 1900. Although the astronomical definition has been discarded, the cesium-based definition remains in use today.
