This document describes the labels used to annotate the DiMSUM data, including counts for the training data in the 1.5 release.

Multiword Expressions

Multiword Expressions (MWEs) are contiguous or gappy groupings of tokens that function semantically as a lexical unit. STREUSLE MWE Guidelines (In this release, unlike STREUSLE, we do not include weak MWEs.)

Token-level MWE-positional flags (5th field of the data) are as follows (with frequency counts):

63264 O  Not part of or inside any MWE
  675 o  Not part of any MWE, but inside the gap of an MWE
 4208 B  First token of an MWE, not inside a gap
   24 b  First token of an MWE, inside the gap of another MWE
 5623 I  Token continuing an MWE, not inside a gap
   32 i  Token continuing an MWE, inside the gap of another MWE
=====
73826 tokens

Class Labels

Many of the lexical expressions (single-word and multiword) in the corpus have been manually annotated with semantic classes called supersenses. There are 41 unique class labels. They are listed below with their token frequencies.

These supersenses appear in the 8th field of the data. For MWEs, they are only listed with the first (B or b) token, but should be interpreted as applying to the entire expression.

Noun Supersenses

All of the 26 noun supersenses defined in WordNet are attested, including a miscelleneous supersense that we call n.other (traditionally, noun.Tops), which applies to vague words like "stuff". STREUSLE guidelines, examples for noun supersense annotation.
