A web-based tool for extracting keywords and terminology from documents uploaded by users.
I implemented the front end and the back end together with the full pipeline: from uploading a document (Word, PDF, and more), to processing it on the server, extracting plain text, automatically annotating with linguistic information, extracting the terminology, to providing the output to the user. The tool can also extract bilingual terminology.
