What is The ICNALE?

The International Corpus Network of Asian Learners of English (ICNALE) is one of the largest learner corpora focusing on Asian leaners. The ICNALE-Written holds 1.3 M words of controlled essays written by 2,600 college students in 10 Asian countries and areas as well as 200 English Native Speakers. The ICNALE-Spoken and the ICNALE-Proofread, both of which are comparable to the ICNALE-Written, are now under construction.

The ICNALE is designed as a reliable database for international contrastive interlanguage analysis and it can also be used for studies of the World Englishes in Asia. The ICNALE has been compiled by Dr. Shin'ichiro Ishikawa of Kobe University, Japan in the research project supported by the MEXT (Ministry of Education, Science, Sports and Culture of Japan) / JSPS (Japan Society for the Promotion of Science), Grant-in-Aid for Scientific Research (B), No. 22320104.2 (2010.4-2013.3) and No. 25284104 (2014.4-2016.3).

Focus on Asian Learners

The ICNALE includes essays and speeches produced by EFL learners (China, Indonesia, Japan, Korea, Taiwan, Thailand) and ESL users (Hong Kong, Singapore, Pakistan, Philippines) in Asia, as well as English native speakers (US, UK, Australia, etc.), covering all of the Inner, Outer, and Expanding Circles in Asia (Kachru, 1992).

Control on the Conditions for L2 Production

In order to conduct a reliable contrastive study, we need to control varied factors potentially influencing the language of the essays (Adel, 2008). In the ICNALE, conditions for writing and speaking are controlled as strictly as possible.

(A) It is important for college students to have a part time job.
(B) Smoking should be completely banned at all the restaurants in the country.
Time  20 to 40 mins for one essay  60 second for one speech 
Length  200 to 300 words (+-10%)  Not controlled 
Dictionary use  No  No 
Spell-checker use  Compulsory  --- 










Control on L2 Proficiency of Participants

Another factor influencing L2 production is a learner's L2 proficiency. In the project, based on the participants' scores in the standard L2 proficiency tests such as TOEIC or TOEFL or in the standard vocabulary size test (VST) (Nation, & Begler, 2007), we classified participants' proficiencies into four levels: A2 (Waystage), B1_1 (Threshold: Lower), B1_2 (Threshold: Upper), and B2+ (Vantage or higher). These are identical with the levels proposed in the CEFR (Common European Framework of Reference). The table below shows the percentage of participants of the ICNALE-Written at each proficiency level .

Comparable NS Data

The ICNALE also includes the L1 production data by English native speakers. The same topics and the same conditions are given to learners and native speakers, which assures high reliability in NS-NNS contrastive studies.


The ratio of nationalities of native speakers (The ICNALE-Written)




In case of the ICNALE-Written, the ENS Module includes 400 essays written by 200 writers, who are subdivided into ENS1 (ENS_001-100) and ENS 2 (ENS_101-200). ENS 1 writers are college students, while ENS 2 writers are employed (the average age is 34.3). Countries included in the ENS module (ENS1 + ENS2) are USA (57.0%), United Kingdom (14.0%), Canada (14.0%), Australia (8.5%), and New Zealand (6.5%).  The ICNALE covers both of the British English and American English.









How to Access The ICNALE

There are two ways for you to use the ICNALE. One is The ICNALE Online, where you can conduct KWIC Search, Collocation Search, Wordlist Search, and Keywords Search.
