Introduction to the NLP-Interview-Notes Project
Overview
The NLP-Interview-Notes project serves as a comprehensive resource for individuals preparing for natural language processing (NLP) interviews. Created through the authors' accumulated experiences and reflections from interviews, this repository is a collection of study notes and materials on various NLP topics. It consolidates frequently asked interview questions across different NLP fields, offering a valuable resource for both aspiring and experienced NLP practitioners.
Sections
NLP Learning and Common Interview Topics
This section of the project is divided into various subsections addressing common topics in NLP interviews, focusing on algorithms and techniques widely used in the field.
1. Information Extraction
-
Named Entity Recognition (NER)
- Explore key algorithms like Hidden Markov Models (HMM), Maximum Entropy Markov Models (MEMM), and Conditional Random Fields (CRF), each explained in detail with related interview questions.
- Discover modern methods in NER such as DNN-CRF, and tricks to enhance NER performance, including techniques specific to Chinese NER tasks.
-
Relation Extraction
- Learn about different approaches used in relation extraction, such as template matching and distant supervision.
- Understand the processes behind complex relations and the challenges they pose.
-
Event Extraction
- Delve into the concept of event extraction, exploring fundamental tasks like trigger detection and argument identification.
- Familiarize yourself with the methods used in event extraction, ranging from pattern matching to deep learning techniques.
2. Pre-training Algorithms in NLP
-
TF-IDF
- Get insights into this classic approach for evaluating word importance in a document, along with its calculation methods, strengths, and limitations.
-
Word2Vec
- Understand word2vec’s architectures: the CBOW and Skip-gram models, and their comparative advantages.
- Learn about optimization strategies like Huffman coding and negative sampling, which enhance word2vec model performance.
Project Features
