CSniper

CSniper (Corpus Sniper) is a tool that implements

  1. a web-based multi-user scenario for identifying and annotating linguistic phenomena (e.g. non-canonical grammatical constructions) in large corpora, based on linguistic search queries and
  2. evaluation of annotation quality by measuring inter-rater agreement.

This annotation-by-query approach efficiently harnesses expert knowledge to identify instances of linguistic phenomena that are hard to identify by means of existing purely automatic annotation tools. In addition, CSniper uses inbuilt machine learning mechanism (using an SVM with tree-kernel) to rank search results, facilitating the annotation process.
