Syntactically Look-Ahead Attention Network for Sentence Compression
Table 8: Compression ratios in characters on the BNC Corpus. The notations are the same as in Table 6.
['[EMPTY]', '[EMPTY]', '[BOLD] ALL  [BOLD] CR', '[BOLD] ALL  [BOLD] ΔC', '[BOLD] LONG  [BOLD] CR', '[BOLD] LONG  [BOLD] ΔC']
We used compression ratios in tokens to evaluate each method in this paper. However, compression ratios in characters are also used for evaluating sentence compression performance. Thus, we also report compression ratios in characters of our methods to support a fair comparison between sentence compression methods. Note that in both tables, ΔC is calculated with compression ratios in characters.
