Project mention: Show HN: Mandarin Word Segmenter with Translation | news.ycombinator.com | 2025-02-04
Thanks for the kind words!
I'm using Jieba[0] because it hits a nice balance of fast and accurate. But I'm initializing it with a custom dictionary (~800k entries), and have added several layers of heuristic post-segmentation. For example, Jieba tends to split up chengyu into two words, but I've decided they should be displayed as a single word, since chengyu are typically a single entry in dictionaries.

rasa
💬 Open source machine learning framework to automate text- and voice-based conversations: NLU, dialogue management, connect to Slack, Facebook, and more - Create chatbots and voice assistants
Project mention: Eliza Reanimated Published in IEEE Annals of the History of Computing | news.ycombinator.com | 2025-06-20Right before LLMs broke into the scene we had a few techniques I was aware of:
* Personality Forge uses a rules-based scripting approach [0]. This is basically ELIZA extended to take advantage of modern processing power.
* Rasa [1] used traditional NLP/NLU techniques and small-model ML to match intents and parse user requests. This is the same kind of tooling that Google/Alexa historically used, just without the voice layer and with more effort to keep the context in mind.
Rasa is actually open source [2], so you can poke around the internals to see how it's implemented. It doesn't look like it's changed architecture substantially since the pre-LLM days. Rhasspy [3] (also open source) uses similar techniques but in the voice assistant space rather than as a full chatbot.

Qwen
The official repo of Qwen (通义千问) chat & pretrained large language model proposed by Alibaba Cloud.
Project mention: Running Qwen, Nearly as Powerful as DeepSeek, on a MacBook Pro | dev.to | 2025-02-05Qwen (Qwen GitHub Repository) has been gaining attention recently as a powerful open-source large language model (LLM). I decided to give it a spin on my MacBook Pro using Ollama, a platform designed for running local LLMs. While Qwen2.5-Max boasts the highest performance, my setup could only handle the smaller Qwen2.5 (32B) model. Here's what I found!

Project mention: What is the Most Effective AI Tool for App Development Today? | dev.to | 2025-08-17
At the core of many AI-powered applications are foundational models—large language models (LLMs) and APIs that provide the intelligence for features like natural language processing, image recognition, and decision-making. These tools serve as the brain of the app, processing inputs and generating outputs that feel intuitive and human-like.

Project mention: WhisperNER: Unified Open Named Entity and Speech Recognition | news.ycombinator.com | 2024-11-21
only the last string is a LOC named entity. Of course you can change definitions from the standard ones if you like, but then you should be careful not to compare with tools that use the original standard definition of NER such as flairNLP [1].
