Abstract
Purpose
Sentiment identification of Chinese text faces many challenges, such as requiring complex preprocessing steps, preparing various word dictionaries carefully and dealing with a lot of informal expressions, which lead to high computational complexity.
Design/methodology/approach
A method based on Chinese characters instead of words is proposed. This method represents the text into a fixed length vector and introduces the chi-square statistic to measure the categorical sentiment score of a Chinese character. Based on these, the sentiment identification could be accomplished through four main steps.
Findings
Experiments on corpus with various themes indicate that the performance of proposed method is a little bit worse than existing Chinese words-based methods on most texts, but with improved performance on short and informal texts. Especially, the computation complexity of the proposed method is far better than words-based methods.
Originality/value
The proposed method exploits the property of Chinese characters being a linguistic unit with semantic information. Contrasting to word-based methods, the computational efficiency of this method is significantly improved at slight loss of accuracy. It is more sententious and cuts off the problems resulted from preparing predefined dictionaries and various data preprocessing.

Abstract
Purpose
The purpose of this study is to examine if the international experience of a family firm’s chairman, second-generation managers and other top managers all have impacts of different strengths using information about Chinese family firms’ international expansion.
Design/methodology/approach
Matching tactics and dynamic Heckman 2-stage analysis were applied to data on 766 publicly-listed Chinese family businesses covering 2008–2014.
Findings
The international experience of the chairman, second-generation family managers and other senior managers all were found to correlate with the proportion of a firm’s revenue earned abroad, as well as with the number of its cross-border mergers and acquisitions. The impact of a chairman’s international experience is stronger than the impact of the other two groups when internationalization is measured in terms of the proportion of revenue earned overseas. The second-generation managers’ international experience is the most influential when internationalization is measured in terms of the number of cross-border mergers and acquisitions.
Originality/value
This paper bridges agency theory with upper echelons theory in the context of the family business. The findings contribute to the scholarly understanding of family business by illuminating the mechanisms through which second-generation managers may influence family firms’ internationalization. They also enrich the knowledge of family firms in China.
