在这篇文章中，我们介绍了ESCOLEX，第一个欧洲葡萄牙语儿童词汇数据库与年级水平调整词频统计。ESCOLEX从320万个单词的语料库中计算，提供了从171本小学和中学教科书中提取的48，381个单词形式，供6至11岁的葡萄牙教育系统前六年级的儿童使用。与其他儿童年级数据库一样（例如，卡罗尔，戴维斯，和里奇曼，1971年;科拉尔，费雷罗，和Goikoetxea，行为研究方法，41，1009-1017，2009年; Lété，Sprenger-Charolles，和Colé，行为研究方法，仪器，和计算机，36，156-166，2004年;芝诺，伊文思，米勒德，Duvvuri，1995年），ESCOLEX为每个等级提供了四个频率指数：总体词频（F）、所选教科书的离散指数（D）、每百万字的估计词频（U）和标准词频指数（SFI）。它还提供了一种新的测量方法，上下文多样性（CD）。此外，还提供了从P-PAL（一个基于欧洲葡萄牙语语料库的词汇数据库; Soares，Comesaña，Iriarte，Almeida，Simbes，Costa，.，马查多，2010年; Soares，Iriarte，Almeida，Simbes，Costa，França，..，Comesaña，出版中）中提取的单词及其词性中的字母数、音节数、音节结构和成人频率。ESCOLEX将是一个有用的工具，无论是对语言处理和发展感兴趣的研究人员和需要调整到儿童的发展阶段的口头材料的专业人士。ESCOLEX可以随本文沿着下载，也可以从http://p-pal.di.uminho.pt/about/databases下载。
In this article, we introduce ESCOLEX, the first European Portuguese children’s lexical database with grade-level-adjusted word frequency statistics. Computed from a 3.2-million-word corpus, ESCOLEX provides 48,381 word forms extracted from 171 elementary and middle school textbooks for 6- to 11-year-old children attending the first six grades in the Portuguese educational system. Like other children’s grade-level databases (e.g., Carroll, Davies, & Richman, 1971; Corral, Ferrero, & Goikoetxea, Behavior Research Methods, 41, 1009–1017, 2009; Lété, Sprenger-Charolles, & Colé, Behavior Research Methods, Instruments, & Computers, 36, 156–166, 2004; Zeno, Ivens, Millard, Duvvuri, 1995), ESCOLEX provides four frequency indices for each grade: overall word frequency (F), index of dispersion across the selected textbooks (D), estimated frequency per million words (U), and standard frequency index (SFI). It also provides a new measure, contextual diversity (CD). In addition, the number of letters in the word and its part(s) of speech, number of syllables, syllable structure, and adult frequencies taken from P-PAL (a European Portuguese corpus-based lexical database; Soares, Comesaña, Iriarte, Almeida, Simões, Costa, …, Machado, 2010; Soares, Iriarte, Almeida, Simões, Costa, França, …, Comesaña, in press) are provided. ESCOLEX will be a useful tool both for researchers interested in language processing and development and for professionals in need of verbal materials adjusted to children’s developmental stages. ESCOLEX can be downloaded along with this article or from http://p-pal.di.uminho.pt/about/databases.
