NLP literature reading summary

In recent years, I have read a lot of literature , But there is no systematic summary , In particular, they often get into dead ends , therefore , Today, it has been consolidated @CQU Brother in brother   Summary of the   How to read NLP The paper  , Make a systematic summary of some of them .

1. Literature search and classification

When facing a new topic , Literature search and classification are extremely important , There are mainly two core issues ：

(1) Is the literature you are looking for “ Good enough. ”？

(2) How to classify documents ？

1.1    Literature search

After deciding to start a research direction , The first is to read a lot of papers in this direction ,NLP There are reference websites ：

• ACL Anthology： This is a ACL Learn to build websites , Support the free download of most international academic conference papers in this field , It even includes academic conferences hosted by other organizations , for example COLING、IJCNLP etc. .

• arXiv： This is a pre published website , Generally, many researchers will put many articles that have been submitted but have not been published into arxiv Let us know that the research content in this area has been done , There is no need to do repetitive work .
• DBLP： This is a powerful integrated database system of computer English literature with the author as the core of research results in the computer field .

While searching the literature, we also need to pay attention to the first problem mentioned above ,“ Good enough. ” It means that this document is of good quality . Generally speaking , The following indicators can be used to identify high-quality articles ：

• Journal Publishing / meeting
• Number of citations
• Publishing organization / personal
• Is there a source code

From the perspective of publications and conferences ,NLP Refer to the following meetings for directions / Periodical ：

ACL	meeting	http://dblp.uni-trier.de/db/conf/acl/	NLP
EMNLP	meeting	http://dblp.uni-trier.de/db/conf/emnlp/	NLP
NAACL	meeting	http://dblp.uni-trier.de/db/conf/naacl/	NLP

In the above table , The addresses of the meetings are from DBLP .

1.2 Literature induction

After downloading the paper , Scientific classification and management of documents are also needed , This will help you quickly find your downloaded papers in the later stage . Here you can refer to ：

• Literature sources —— Build folders based on conference and journal names
• Whether to pre publish
• Research questions —— You can also subdivide the research problem , Further make a more detailed classification （ recommend ）
• Method / Model ——CNN, RNN, Bert, Prompt etc.
• An optimization method

Reasonable classification can help you sort out the literature and summarize .

2. Literature reading and notes

Literature should not only be read , Take notes ！

2.1 Reading order

In order to quickly know the author's research problems 、 Content and conclusion , There must be a set of effective thesis reading methods , Here is the recommended reading sequence ：

• Title+Abstract—— Generally speaking , The general research content of this article can be obtained in the title , It is usually also used for you to quickly retrieve the content related to your own research , However, the titles of some papers are very implicit , It may make us miss , for example Attention is all you need. Further reading the abstract can get the core of the article more effectively , Here also need to pay attention , Some articles may have done the same research as themselves , But because it is not its core innovation, it is not written in the summary , This requires further reading .
• Abstract+Introduction (The second half)—— Because the first half of the introduction mostly introduces the research background and early research , Only the latter half is my job , So the core looks at the second half .
• Experiments+Conclusion—— Learn the author's experimental ideas and analytical methods , Get effective research conclusions
• Proposal—— Read according to your sensitivity , Analyze the differences and effects between the author's work and himself

2.2 note

After reading , You must not forget to take notes , After taking notes of documents , It can help you quickly compare the differences of various papers in the later stage , And used to summarize .

It's recommended here up Master's note taking method , By building a table , Summarize the details of each document ：

 3. Discussion and summary

Discussion and summary is a good way to improve your understanding of the article 、 Means of digestion and absorption . After reading a document , Often only one-sided grasp of the problem of article research 、 Methods and conclusions , But there may be a lack of sufficient understanding of the internal logic , meanwhile , Also because of the limitations of their knowledge , It is often difficult to find the problems in the article .

At a time like this , It is best to be able to have a more detailed discussion and analysis with others , Try to persuade others , Answer each other's questions , So that I can understand the article more thoroughly .
