Chinese lexical database (CLD) : A large-scale lexical database for simplified Mandarin Chinese.

Area of Science:

• Lexicography
• Psycholinguistics
• Computational Linguistics

Background:

• Lexical databases are crucial for understanding word processing.
• Existing resources for simplified Chinese are limited in scope and detail.
• A comprehensive lexical database is needed to support research in Chinese language and cognition.

Purpose of the Study:

• To introduce the Chinese Lexical Database (CLD), a large-scale lexical resource for simplified Chinese.
• To provide a wide range of lexical information, including frequency, complexity, and phonological measures.
• To make the CLD publicly available for research purposes.

Main Methods:

• Compiled a database of 48,644 simplified Chinese words (one- to four-character).
• Collected extensive lexical information: categorical predictors, frequency, complexity, neighborhood density, orthography-phonology consistency, and information-theoretic measures.
• Evaluated the database's utility by analyzing lexical decision and naming latencies.

Main Results:

• The CLD contains over 48,000 words with rich lexical features.
• Lexical variables from the CLD demonstrate significant explanatory power for word processing latencies.
• The database effectively predicts experimental data in lexical decision and naming tasks.

Conclusions:

• The Chinese Lexical Database (CLD) is a valuable and comprehensive resource for Chinese linguistics and psycholinguistics.
• The lexical variables provided are robust predictors of word processing.
• The CLD will facilitate future research on the cognitive aspects of the Chinese language.
