OpenHarmony Paper Club “ Visiting papers ” Method ：

Coach Ou Jianshen of gnawing paper Club ( Huawei OpenHarmony Director of open source and developer operations )：

“ Visiting papers ” The purpose of this method is to help students find gold in the paper library

Find the baby you want . This article is based on coach Ou Jianshen of the club “ Visiting papers ” On the way , Let's introduce OpenHarmony Paper Club .

OpenHarmony A brief introduction to the gnawing paper Club

OpenHarmony Growth plan —“ Paper Club ”（ hereinafter referred to as “ Paper Club ”） Is in 2022 year 1 month 11 A daily activity of the day （

OpenHarmony The second live sharing meeting of knowledge empowerment of growth plan

） Born in . At the live sharing meeting , Ou Jianshen introduced his experience of gnawing papers , Guide you to easily cut into the high-level track of technical research , Planned for everyone “ Gnawing paper （ The literature ）— Technical article output — Open source code submission — Technical experts ” The growth path of . The participants were greatly encouraged ,60+ My classmates are eager to try . After the kick-off meeting , A group of small partners are determined to practice “ Gnawing paper ” Road , Embark on the road of pursuing technological freedom .

The gnawing paper club was established ！

Now there is a club input method framework

The team 、 Compression algorithm

ELT.ZIP

The team's articles are included .

“ Stroll ” After finishing my thesis, I saw these landscapes

The author uses “ Visiting papers ” Methods found some very valuable babies , The process of using this method is as follows ：

Method 1 ： By reviewing the paper library ACM Survey Looking for a needle in a haystack

Survey Have the meaning of Overview ,

a survey of XXX

Translation is

XXX An overview of

Summary is a kind of academic paper written after collecting a large amount of intelligence data and comprehensive analysis on a specific topic , It is a kind of scientific literature .

The summary can reflect the latest progress of a branch of discipline or important topic in a certain field 、 Academic insights and suggestions . It can often reflect the new trends of related problems 、 New trends 、 A new level 、 New principles and new technologies, etc .

Way of thinking ：

Implementation steps ：

Step one

： Academic key words + ("a survey of" || "a survey on") stay

Review paper library ACM Survey

Search in, for example, this group of academic keywords Input Method Framework,a survey of Input Method Framework The search results are as follows ：

If you don't understand , take it easy , Look at step two .

Step two

： Right click to translate .

Step three

： Look through it and see what's good .

Practical experience ：

1） It is found in practice that if the keyword +a survey of No relevant review can be found in the paper library , Try changing keywords .

For example, the author found that a survey of Input Method Framework I can't find much satisfactory paper information , So I changed it to a survey of Input Method.

2） The paper library doesn't have to stick to ACM Survey, There are many more to use , such as

IEEE

. You can also use academic search engines , for example

Deep academic search

Biefield academic search engine

wait .

3） Browsing the foreign language thesis database requires a very high mastery of English , Click the right mouse button to translate the web page into Chinese , There may be translation errors, resulting in missing some good things . So I still have to master English more skillfully .

4） The academic search engine with the best experience is

AMiner

, It is a very good academic search engine for computer in academic circles .

The search results are more in line with what you want , Academic keywords used in search have more semantic relevance to search results .

Mainly because it's free （ The author is the student party :joy: ）AMiner It's a non-profit 、 A free academic platform with completely independent intellectual property rights .

5） Enter a through overview

Computing

, Each review paper is the door to a field . Method 2 （ By reviewing the paper library ACM Survey Looking for a needle in a haystack ） Is the golden key to opening the door of a computing field .

Method 2 ： Search for open source technology directly in the paper library

Way of thinking ：

Implementation steps ：

Step one

：

open OpenHarmony Warehouse

, Search the warehouse for

third_party

look for openharmony Introduced component library .

Step two

： double , Get your eyes on fire . for example ：

Look for open source technologies related to compression algorithms , In the process of searching, the author found an open source technology lossless compression algorithm
LZ4
.

Look for open source technologies related to the input method framework , The author also found an open source keyboard mapping table compiler and support library
libxkbcommon
, This sum OpenHarmony 3.1 Release New mouse in version 、 keyboard 、 The basic functions of the touch pad support .

Step three

： Put in openharmony Open source technology found in the introduced component library

LZ4

Search the academic search engine for .

Practical experience

1） adopt openharmony Many treasures can be found in the warehouse , Can not be limited to third_party Component library . For example, the author is OpenHarmony / app_samples The warehouse found a lightweight input method application ——kikainput. It supports running OpenHarmony OS On your smart terminal , This is of great help to the author's subsequent paper .2） stay openharmony In the introduced component library, find the papers of open source technology to gnaw , To participate in OpenHarmony Under construction , It's a cool thing .

“ Visiting papers ” Search in the paper library when “OpenHarmony” What will you see ？

Use academic keywords “OpenHarmony” Search for papers , Very few results have been obtained . Only one paper on memory security flaw detection through data-driven source code annotation indirectly mentioned OpenHarmony IoT Memory corruption in the operating system kernel . Link to the paper ：https://linkspringer.53yu.com/chapter/10.1007/978-3-030-88323-2_7

OpenHarmony It is still in an early stage of development , The wind breaks the waves , Sail the clouds straight to the sea . Believe with OpenHarmony Version evolution of , More people devote themselves to OpenHarmony in , of OHOS There will be more and more academic discussions and papers . Poke the fog away , The scenery ahead will become more and more beautiful, attracting more people to stop and watch .
