Chipola: A Chinese Podcast Lexical Database for capturing spoken language nuances and predicting behavioral data.
Article in Behavior research methods, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
This study introduces Chipola, a Chinese Podcast Lexical Database derived from a large-scale collection of Chinese podcast transcripts. Due to the spoken nature of podcasts, such a podcast lexical database can accurately capture the nuances of spoken language in Chinese. Chipola was developed based on a corpus that comprises 31.2 million word tokens and 41.7 million character tokens, featuring a vocabulary of 88,085 unique words and 4,613 unique characters. Lexical variables such as frequency, context diversity, and part-of-speech information are also included. Findings of interest are as follows. First, Chipola captures the spoken Chinese features, such as the core spoken vocabulary. Second, it outperforms other lexical databases in predicting third-party behavioral data. Third, its rich text-level information enables educators to simulate Chinese lexical input on daily podcast listening, which provides pedagogical insights for the overall effects of language exposure. To summarize, Chipola presents an innovative and valuable resource with significant implications and applications in areas such as psychology and language education.
