Also, decisions on when references are given within the body of a chapter or postponed to end-of-chapter notes are inconsistent, some technical terms (e.g., 'spurious ambiguity') are not explained at the first point at which they are mentioned, and others (e.g., 'gap degree') are not explained at all.
given that these problems are mostly textual and in general do not impede the reader's understanding, this book serves as a very useful and up to date survey of the burgeoning research area of dependency parsing.
