Couting quantifiers play an important role in question answering or knowledge base curation, but are neglected by prior work. This paper develops the first full-fledged system for extracting counting information from text, called CINEX.

CINEX successfully deals with three challenges:

• non-maximal training seeds due to the incompleteness of knowledge bases;
• sparse and skewed observations in text sources;
• high diverstiy of liguistic patterns.

CINEX architecture is shown in figure 1. CINEX can be divided into two important stages: CQ Recgnition and CQ Consolidation. Firstly, CINEX uses the seeds from WIKIDATA and train two different models to generate CQ candidates. The models are CRF++ with n-gram features and bidirectional LSTM-CRF repectively. Then CINEX consolidates the tokens expressing counting or compositionality information into a single prediction based on mention consolidation with confidence scores and count zero.
