This archive contains two folders -- one per diachronic representation method -- as well as this README. The folders each contain four folders, which contain the models for their respective languages. As can be inferred from the small datasize, most of the earlier models are not reliable and should not be used, but are still made available.

The models were created with data from the Finnish Sub-corpus of the Newspaper and Periodical Corpus of the National Library of Finland (National Library of Finland, 2011). We used everything in the corpus.

The models were created with data from the Kubhist 2 corpus (Språkbanken) -- more precisely, the data dumps available at After a manual evaluation of Swedish embeddings trained without pre-processing seemed to show that the embeddings were of low quality, we retrained models, only keeping sentences that were at least 10 tokens long and were constituted of at least 50% of lemmas as per the KORP processing pipeline (Borin et al, 2012).

The models were created with data from the Delpher newspaper archive (Royal Dutch Library, 2017), through data dumps for newspapers until and including 1876, and through API hits for articles from 1877 to 1899 (included).

	For anything pre-1877 we discarded full texts that had, in the metadata, anything else than exclusively nl or NL as a language tag.
	For the full texts between 1877 and 1899: we queried the API for all items in the “artikel” category that contained the determiner de.

Our assumption was that most articles should contain de at least once, and those that didn't were too short to be deemed interesting. A subsequent study showed that was not exactly the case, but we were reassured by the fact that left-out articles were probably "shipping or financial reports" (thanks go to Melvin Wevers). We also did not include the colonial newspapers for our embeddings. This is motivated by our research questions. A list of removed newspapers is available on request.

The models were created with data from the British Library Newspapers collection (link), the Nichols collection (link), and the Burney collection (link). We used everything in the corpora. For English, only SGNS_ALIGN models are available. We thank Gale Cengage for their help with this project.

Word embeddings

For every language, we train diachronic embeddings as follows. We divide the data in 20-year time bins. We train SGNS_UPDATE and SGNS_ALIGN models. Current research on German (Schlechtweg et al, 2019) and English (Shoemark et al, 2019) indicates you should use the SGNS_ALIGN models. For EN, FI, NL, no tokens (including punctuation) were removed nor altered, aside from lowercasing. For SV, see above. Parameters are as follows: SGNS architecture (Mikolov et al 2013), window size of 5, frequency threshold of 100, 5 epochs, 300 dimensions (or 100 for EN).

	For SGNS_UPDATE: We first train a model for the first time bin t. To train the model for t+1, we use the t model to initialise the vectors for t+1, set the learning rate to correspond to the end learning rate of t, and continue training. This approach, closely following Kim et al (2014), has the advantage of avoiding the need for post-training vector space alignment.

The Python snippet below, which makes use of gensim (Rehurek and Sojka, 2010), illustrates the approach. Special thanks go to Sara Budts.

## dict_files[key] is a dictionary with double decades as keys and a corresponding LineSentence object as value:

count = 0
for key in sorted(list(dict_files.keys())):

    if count == 0: ## This is the first model.

        model = gensim.models.Word2Vec(corpus_file=dict_files[key], min_count=100, sg=1 ,size=300, workers=64, seed=1830, iter=5),"KIM",lang+"_"+str(timebin)+".w2v"))
        print("Model saved, on to the next\n")
        count += 1

    if count &gt; 0: ## this is for the subsequent models.
        print("model for double decade starting in",str(key))
        model = gensim.models.Word2Vec.load(os.path.join(data_path_final,"KIM",lang+"_"+str(timebin-20)+".w2v"))
        print("previous model loaded")

        model.build_vocab(corpus_file=dict_files[key], update=True)
        model.train(corpus_file=dict_files[key], total_words = model.corpus_count, total_examples = model.corpus_count, start_alpha = model.alpha, end_alpha = model.min_alpha, epochs=model.epochs),"KIM",lang+"_"+str(timebin)+".w2v"))

	For SGNS_ALIGN: We independently train models for all time bins. The models in this repository are NOT aligned, leaving you the choice of how to align them. For example, here is a link to code by Ryan Heuser to do just that. Models were trained with the count == 0 scenario in the snippet above.
