Natural language processing: enabling computers to understand and process human language
Natural language processing: enabling computers to understand and process human language
Natural Language Processing (NLP) is an important and exciting technology in the field of artificial intelligence. Its goal is to enable computers to understand, parse and generate human language. The development of NLP has made tremendous progress, enabling computers to better interact with humans and achieve a wider range of applications. This article will discuss the concepts, technologies, applications and future prospects of natural language processing
The concept of natural language processing
Natural language processing is a The study of enabling computers to understand and process human language. The complexity and ambiguity of human language make computers face huge challenges in understanding and processing. The goal of NLP is to develop algorithms and models that enable computers to extract information from text, recognize semantics, generate language, and even conduct conversations.
Key technologies of NLP
1. Word segmentation and tokenization
Tokenization is the process of splitting text into words or words, while tokenization is to add tags such as part of speech to each word. These two steps are the basis of natural language processing and provide basic support for subsequent processing
2. Semantic analysis
Semantic analysis involves understanding the meaning of sentences, including the relationship between words, context, etc. It enables computers to infer the true intention of a sentence
3. Information extraction
Information extraction refers to extracting valuable information from text Information, such as extracting key events, names, places, etc. from the news
4. Machine translation
The purpose of machine translation is to convert one language into another language, which requires the conversion of word meaning, grammar and context
5. Sentiment Analysis
Sentiment analysis is a method used to determine the emotional color of text, through which people’s moods and emotions can be understood
6. Dialogue system
The goal of the dialogue system is to achieve natural dialogue between computers and humans. It can be applied to various scenarios such as customer support, virtual assistants, etc.
Application fields of NLP
1. Search engine
Search engines use NLP technology to understand the user’s search intent and return results relevant to the user’s query.
2. Social media analysis
NLP technology can analyze large amounts of text data on social media , helping enterprises understand user emotions, trends and feedback
3. Automatic text summarization
NLP can automatically extract key information from large amounts of text , generate concise summaries.
4. Medical Diagnosis and Research
NLP technology can assist doctors in analyzing medical records and assisting in diagnosis and research
5. Financial field
NLP can analyze news, reports and other texts to help financial practitioners make decisions.
Future Outlook
With the continuous advancement of artificial intelligence technology, natural language processing (NLP) The application prospects are broader. In the future, we can look forward to more intelligent dialogue systems, more accurate machine translation, deeper sentiment analysis, and more. At the same time, NLP will also be combined with technologies in other fields to achieve more new innovations and applications
Natural language processing has become the leading technology in the field of artificial intelligence. an important branch. It enables computers to better understand and process human language. With the continuous development of technology, natural language processing will continue to create value in various fields and bring more convenience and possibilities to our lives

Context-augmented AI coding assistant using Rag and Sem-Rag
Jun 10, 2024 am 11:08 AM
Improve developer productivity, efficiency, and accuracy by incorporating retrieval-enhanced generation and semantic memory into AI coding assistants. Translated from EnhancingAICodingAssistantswithContextUsingRAGandSEM-RAG, author JanakiramMSV. While basic AI programming assistants are naturally helpful, they often fail to provide the most relevant and correct code suggestions because they rely on a general understanding of the software language and the most common patterns of writing software. The code generated by these coding assistants is suitable for solving the problems they are responsible for solving, but often does not conform to the coding standards, conventions and styles of the individual teams. This often results in suggestions that need to be modified or refined in order for the code to be accepted into the application
Can fine-tuning really allow LLM to learn new things: introducing new knowledge may make the model produce more hallucinations
Jun 11, 2024 pm 03:57 PM
Large Language Models (LLMs) are trained on huge text databases, where they acquire large amounts of real-world knowledge. This knowledge is embedded into their parameters and can then be used when needed. The knowledge of these models is "reified" at the end of training. At the end of pre-training, the model actually stops learning. Align or fine-tune the model to learn how to leverage this knowledge and respond more naturally to user questions. But sometimes model knowledge is not enough, and although the model can access external content through RAG, it is considered beneficial to adapt the model to new domains through fine-tuning. This fine-tuning is performed using input from human annotators or other LLM creations, where the model encounters additional real-world knowledge and integrates it

Five schools of machine learning you don't know about
Jun 05, 2024 pm 08:51 PM
Machine learning is an important branch of artificial intelligence that gives computers the ability to learn from data and improve their capabilities without being explicitly programmed. Machine learning has a wide range of applications in various fields, from image recognition and natural language processing to recommendation systems and fraud detection, and it is changing the way we live. There are many different methods and theories in the field of machine learning, among which the five most influential methods are called the "Five Schools of Machine Learning". The five major schools are the symbolic school, the connectionist school, the evolutionary school, the Bayesian school and the analogy school. 1. Symbolism, also known as symbolism, emphasizes the use of symbols for logical reasoning and expression of knowledge. This school of thought believes that learning is a process of reverse deduction, through existing
To provide a new scientific and complex question answering benchmark and evaluation system for large models, UNSW, Argonne, University of Chicago and other institutions jointly launched the SciQAG framework
Jul 25, 2024 am 06:42 AM
Editor |ScienceAI Question Answering (QA) data set plays a vital role in promoting natural language processing (NLP) research. High-quality QA data sets can not only be used to fine-tune models, but also effectively evaluate the capabilities of large language models (LLM), especially the ability to understand and reason about scientific knowledge. Although there are currently many scientific QA data sets covering medicine, chemistry, biology and other fields, these data sets still have some shortcomings. First, the data form is relatively simple, most of which are multiple-choice questions. They are easy to evaluate, but limit the model's answer selection range and cannot fully test the model's ability to answer scientific questions. In contrast, open-ended Q&A
SOTA performance, Xiamen multi-modal protein-ligand affinity prediction AI method, combines molecular surface information for the first time
Jul 17, 2024 pm 06:37 PM
Editor | KX In the field of drug research and development, accurately and effectively predicting the binding affinity of proteins and ligands is crucial for drug screening and optimization. However, current studies do not take into account the important role of molecular surface information in protein-ligand interactions. Based on this, researchers from Xiamen University proposed a novel multi-modal feature extraction (MFE) framework, which for the first time combines information on protein surface, 3D structure and sequence, and uses a cross-attention mechanism to compare different modalities. feature alignment. Experimental results demonstrate that this method achieves state-of-the-art performance in predicting protein-ligand binding affinities. Furthermore, ablation studies demonstrate the effectiveness and necessity of protein surface information and multimodal feature alignment within this framework. Related research begins with "S
