Vectors/metadata

This page describes the fields in the NLPL vector repository catalogue. The catalogue itself is a JSON file, for example, 20.json for the version 2.0 of the Repository.

All field except "id" are optional.

Algorithms

This section lists the distributional algorithms.

• "command": exact command which was run to train the model, for example, "word2vec -min-count 10 -size 100 -window 10 -negative 5 -iter 2 -threads 16 -cbow 0 -binary 0"
• "id": NLPL identifier of the algorithm (integer)
• "name": human-readable name of the algorithm, for example, "Gensim Continuous Skipgram"
• "tool": tool used to train models with this algorithm, for example, "Gensim"
• "url": link to the tool used, for example, "https://github.com/RaRe-Technologies/gensim"
• "version": version of the tool used, for example, "3.6"

Corpora

This section lists the training corpora.

• "NER": whether multi-word named entities were detected and merged into one token (Boolean)
• "case preserved": whether token case was left as is or lowered (Boolean)
• "description": human-readable corpus description, for example, "Gigaword 5th Edition"
• "id": NLPL identifier of the corpus (integer)
• "language": 3-letter ISO language code, for example, "eng"
• "lemmatized": whether the corpus is lemmatized (Boolean)
• "public": whether the corpus is freely available (Boolean)
• "stop words removal": if stop words were removed from the corpus, this field contains a human-readable description of the procedure (e.g., "all functional parts of speech"); otherwise, null
• "tagger": human-readable description of the tagger/lemmatizer used (e.g., "Stanford Core NLP v. 3.6.0"); if no lemmatization was done, null
• "tagset": human-readable description of the PoS tagset used (e.g., "UPoS"); if no tagging was done, null
• "tokens": number of word tokens in the corpus (integer)
• "tool": link to the tool used to generate the corpus, if any (e.g., "https://github.com/RaRe-Technologies/gensim/blob/master/gensim/scripts/segment_wiki.py"); otherwise, null
• "url": link to the corpus, for example, "https://catalog.ldc.upenn.edu/LDC2011T07"

Models

This section lists the distributional models themselves.

• "algorithm": NLPL identifier of the training algorithm used (integer)
• "contents": a list of files stored in the model ZIP archive; each file is described as a dictionary with the filename and format fields
• "corpus": a list of integer NLPL identifiers of the training corpora, for example, [0, 3]
• "creators": a list of persons who trained the model; each person is described as a dictionary with the email and name fields
• "dimensions": dimensionality of the word representations in the model (integer),
• "documentation": usually a link to the details about the model or to the code to run it, for example, "https://github.com/ltgoslo/simple_elmo"
• "handle": persistent NLPL handler of the model, for example, "http://vectors.nlpl.eu/repository/20/1.zip"
• "id": persistent NLPL identifier of the model (integer)
• "iterations": how many epochs (passes over the corpus) were made during training (integer),
• "vocabulary size": the number of words in the model vocabulary, if applicable (integer)
• "window": context window size used during training, if applicable (integer)
