In wordspace: Distributional Semantic Models in R

Verb-Noun Co-occurrence Frequencies from British National Corpus (wordspace)

Description

A table of co-occurrence frequency counts for verb-subject and verb-object pairs in the British National Corpus (BNC). Subject and object are represented by the respective head noun. Both verb and noun entries are lemmatized. Separate frequency counts are provided for the written and the spoken part of the BNC.

Usage

  
DSM_VerbNounTriples_BNC

Format

A data frame with 250117 rows and the following columns:

noun:

noun lemma

rel:

syntactic relation (subj or obj)

verb:

verb lemma

f:

co-occurrence frequency of noun-rel-verb triple in subcorpus

mode:

subcorpus (written for the writte part of the BNC, spoken for the spoken part of the BNC)

Details

In order to save disk space, triples that occur less than 5 times in the respective subcorpus have been omitted from the table. The data set should therefore not be used for practical applications.

Source

Syntactic dependencies were extracted from the British National Corpus (Aston & Burnard 1998) using the C&C robust syntactic parser (Curran et al. 2007). Lemmatization and POS tagging are also based on the C&C output.

Examples

# compile some typical DSMs for spoken part of BNC
bncS <- subset(DSM_VerbNounTriples_BNC, mode == "spoken")
dim(bncS) # ca. 14k verb-rel-noun triples

# dependency-filtered DSM for nouns, using verbs as features
# (note that multiple entries for same relation are collapsed automatically)
bncS_depfilt <- dsm(
  target=bncS$noun, feature=bncS$verb, score=bncS$f,
  raw.freq=TRUE, verbose=TRUE)

# dependency-structured DSM
bncS_depstruc <- dsm(
  target=bncS$noun, feature=paste(bncS$rel, bncS$verb, sep=":"), score=bncS$f,
  raw.freq=TRUE, verbose=TRUE)
