Diachronic collocations, genre, and DiaCollo
This chapter presents the formal basis for diachronic collocation profiling as implemented in the open-source software tool “DiaCollo” and sketches some potential applications to multi-genre diachronic corpora. Explicitly developed for the efficient extraction, comparison, and interactive visualization of collocations from a diachronic text corpus, DiaCollo is suitable for processing collocation pairs whose association strength depends on extralinguistic features such as the date of occurrence or text genre. By tracking changes in a word’s typical collocates over time, DiaCollo can help to provide a clearer picture of diachronic changes in the word’s usage, especially those related to semantic shift or discourse environment. Use of the flexible DDC search engine back-end allows user queries to make explicit reference to genre and other document-level metadata, thus allowing e.g. independent genre-local profiles or cross-genre comparisons. In addition to traditional static tabular display formats, a web-service plugin also offers a number of intuitive interactive online visualizations for diachronic profile data for immediate inspection.
