Tanja Säily is a Postdoctoral Researcher in the Department of Languages at the University of Helsinki. Her research interests include corpus linguistics, digital humanities, historical sociolinguistics, and the concept of productivity in linguistics. She enjoys working collaboratively, especially to develop tools and methods for humanities research. She is currently working in the Helsinki Computational History Group (COMHIS) on social aspects of public discourse in the modern period. In addition, she is a member of two Academy of Finland funded research projects that focus on language change. After defending her PhD dissertation on variation and change in English derivational productivity in 2014, she gained a postdoc position in the project Reassessing language change: the challenge of real time, where she continues her work on productivity in addition to participating in the compilation of a new online resource, the Language Change Database. She is also collaborating with computer scientists to develop corpus-linguistic tools and methods for historical sociolinguistics in the STRATAS project, funded by the Academy of Finland DIGIHUM programme. She is a co-compiler of the Corpora of Early English Correspondence.
My current focus is on lexical productivity and creativity: as a member of two DH research teams, I explore the social embedding of vocabulary change in both public and private discourse in Modern English. Firstly, I collaborate with historians, linguists and computer scientists in the COMHIS research group to study changes in public discourse in large databases of text and metadata, including Eighteenth Century Collections Online (ECCO) and the English Short Title Catalogue (ESTC). Secondly, in the STRATAS project (on which more below), we are developing an open-source environment for analysing neologisms that combines the Corpora of Early English Correspondence with lexicographical sources and contemporary published texts.
I am a member of the project Interfacing structured and unstructured data in sociolinguistic research on language change (STRATAS), funded by the Academy of Finland DIGIHUM programme for 2016–2019 and led by Professor Terttu Nevalainen. Together with Eetu Mäkelä, Mika Hämäläinen and Harri Siirtola, we are developing a toolkit for historical sociolinguistics that will enable researchers to interactively explore the social embedding of language use by combining texts, metadata and visualizations. As noted above, my subproject focuses on neologisms in early English correspondence.
I am also a member of the project Reassessing language change: the challenge of real time, which is funded by the Academy of Finland for 2014–2018 and led by Professor Terttu Nevalainen. One of the main aims of the project is to create a user-updated, fully searchable Language Change Database, which will provide access to the results of previous empirical research on English historical linguistics. In my subproject, I work on variation and change in derivational vs. inflectional productivity, as well as on methods for studying changes proceeding through lexical diffusion.
I have participated in the development of the following tools and methods:
- Text Variation Explorer (TVE), an interactive visualisation tool for comparing corpora (with Harri Siirtola and Terttu Nevalainen); TVE2 is currently under development
- Khepri, an upcoming interface for historical sociolinguistics (with Eetu Mäkelä and Terttu Nevalainen)
- FiCa, an upcoming tool for filtering and categorising corpus data (with Eetu Mäkelä)
- types2, for comparing the frequencies of types, tokens & hapax legomena across subcorpora (with Jukka Suomela)
- Bootstrap Test for R and Matlab, for keyword analysis (with Jefrey Lijffijt and Terttu Nevalainen)
- WordSmith utilities, for splitting WordSmith concordances into separate columns for use in Excel (with Jukka Suomela)
- CEECer, an in-house search engine for the CEEC (with CS students, Samuli Kaislaniemi and Terttu Nevalainen)
