Abstract


A tool for corpus-based lexicon construction. Users can upload a text dataset (corpus) for use in creating an attestation-based lexicon.

This tool is used to manually correct the automatically lemmatized corpus text. Verified lemmatized words plus the context in which they appear will be stored in the Information Retrieval Lexicon. The tool can handle plain text and various XML formats, among which the IMPACT Page XML format and TEI. An important requirement of the tool is that it should be fit to quickly process large quantities of data, that it is a web application that can be run from any computer in the local network, that frequent input actions can be performed with the keyboard, and that the information is presented in such a way that quick evaluation is possible.
