    Examining Scientific Writing Styles from the Perspective of Linguistic Complexity

    Full text link
    Publishing articles in high-impact English journals is difficult for scholars around the world, especially for non-native English-speaking scholars (NNESs), most of whom struggle with proficiency in English. In order to uncover the differences in English scientific writing between native English-speaking scholars (NESs) and NNESs, we collected a large-scale data set containing more than 150,000 full-text articles published in PLoS between 2006 and 2015. We divided these articles into three groups according to the ethnic backgrounds of the first and corresponding authors, obtained by Ethnea, and examined the scientific writing styles in English from a two-fold perspective of linguistic complexity: (1) syntactic complexity, including measurements of sentence length and sentence complexity; and (2) lexical complexity, including measurements of lexical diversity, lexical density, and lexical sophistication. The observations suggest marginal differences between groups in syntactical and lexical complexity.Comment: 6 figure

    Cross-Lingual and Cross-Chronological Information Access to Multilingual Historical Documents

    In this chapter, we present our work in realizing information access across different languages and periods. Nowadays, digital collections of historical documents have to handle materials written in many different languages in different time periods. Even in a particular language, there are significant differences over time in terms of grammar, vocabulary and script. Our goal is to develop a method to access digital collections in a wide range of periods from ancient to modern. We introduce an information extraction method for digitized ancient Mongolian historical manuscripts for reducing labour-intensive analysis. The proposed method performs computerized analysis on Mongolian historical documents. Named entities such as personal names and place names are extracted by employing support vector machine. The extracted named entities are utilized to create a digital edition that reflects an ancient Mongolian historical manuscript written in traditional Mongolian script. The Text Encoding Initiative guidelines are adopted to encode the named entities, transcriptions and interpretations of ancient words. A web-based prototype system is developed for utilizing digital editions of ancient Mongolian historical manuscripts as scholarly tools. The proposed prototype has the capability to display and search traditional Mongolian text and its transliteration in Latin letters along with the highlighted named entities and the scanned images of the source manuscript

    The contribution of corpus linguistics to lexicography and the future of Tibetan dictionaries

    The first alphabetized dictionary of Tibetan appeared in 1829 (cf. Bray 2008) and the intervening 184 years have witnessed the publication of scores of other Tibetan dictionaries (cf. Simon 1964). Hundreds of Tibetan dictionaries are now available; these include bilin gual dictionaries, both to and from such languages as English, French, German, Latin, Japanese, etc. and specialized dictionaries focusing on medicine, plants, dialects, archaic terms, neologisms, etc. (cf. Walter 2006, McGrath 2008). However, if one classifies Tibetan dictionaries by the methods of their compilation the accomplishments of Tibetan lexicography are less impressive. Methodologies of dictionary compilation divide heuristically into three types. First, some dictionaries lack explicit methodology; these works assemble words in an ad hoc manner and illustrate them with invented examples. Second, there are dictionaries that are compiled over very long periods of time on the basis of collections of slips recording attestations of words as used in context. Third, more recent dictionaries are compiled on the basis of electronic text corpora, which are processed computationally to aid in the precision, consistency and speed of dictionary compilation. These methods may be called respectively the 'informal method', the 'traditional method', and the 'modern method'. The overwhelming majority of Tibetan dictionaries were compiled with the informal method. Only five Tibetan dictionaries use the traditional methodology. No Tibetan dictionary yet compiled makes use of the modern method
