不同学科、文档位置和句法结构的文本窗口和短语
Text Windows and Phrases Differing by Discipline, Location in Document, and Syntactic Structure
摘要：
窗口样式、内容、位置和语法结构的知识可用于将文档分类为源自特定学科，或者可用于将文档置于理论与实践谱上。这种区别也在这里使用类型标记比率来区分子语言。基于标题、摘要、引文和章节标题中术语的存在以及二进制独立（BI）和逆文档频率（IDF）权重，计算窗口的统计显著性。窗口的特点进行了研究，通过检查他们的窗口内密度（WWD）和S浓度（SC），集中的各种文件领域（如标题，摘要）的全文。从文档全文开始到结束的窗口出现率在学术领域之间是不同的。不同的句法结构的子语言进行检查，他们的使用被认为是区分特定的学科，更一般地说，理论与实践或知识与应用导向的文件。
英文摘要：
Knowledge of window style, content, location and grammatical structure may be used to classify documents as originating within a particular discipline or may be used to place a document on a theory versus practice spectrum. This distinction is also studied here using the type-token ratio to differentiate between sublanguages. The statistical significance of windows is computed, based on the the presence of terms in titles, abstracts, citations, and section headers, as well as binary independent (BI) and inverse document frequency (IDF) weightings. The characteristics of windows are studied by examining their within window density (WWD) and the S concentration (SC), the concentration of terms from various document fields (e.g. title, abstract) in the fulltext. The rate of window occurrences from the beginning to the end of document fulltext differs between academic fields. Different syntactic structures in sublanguages are examined, and their use is considered for discriminating between specific academic disciplines and, more generally, between theory versus practice or knowledge versus applications oriented documents.
