Norwegian idioms

This is a dataset that consists of 3537 Norwegian idioms and phrases that appear more than 100 times in the online library of the National Library of Norway.
There are 3455 Bokmål idioms and 88 Nynorsk idioms. In the future, we want to add more Nynorsk idioms.

Idioms

all_idioms_freq.json contain all the idioms and their frequency in the online library as key,value pairs
nno_idioms_freq.json contain the Nynorsk idioms and their frequency in the online library as key,value pairs
nob_idioms_freq.json contain the Bokmål idioms and their frequency in the online library as key,value pairs

Idiom completion as an NLP task

In idiom_dataset.json the idioms are split into idiom starts (the first N-1 words) and accepted completions (a list of possible last words to complete the idiom).

This dataset can be used to measure a generative language models' ability to complete well known idioms, or as a masked language modelling task.

It can be loaded as a Datasets dataset like this:

from datasets import Dataset 
import pandas as pd

df = pd.read_json("idiom_dataset.json")
ds = Dataset.from_pandas(df)

The dataset has the columns "idiom_start", "accepted_completions" and "language".
There are 3245 rows, 156 of which there are more than one accepted completion.

Idiom graphs

There is considerable linguistic overlap between the idioms. For example, though there are 3537 unique idioms, there are only 796 unique starter words.
We have arranged the idioms as trees, where the roots are the start words, and the idioms are found by following a path from a root node to a leaf node.
Example:

"alt": {
    "er": {
        "bare": {
            "fryd": {
                "og": {
                    "gammen": {}
                }
            }
        },
        "klappet": {
            "og": {
                "klart": {}
            }
        },
        "såre": {
            "vel": {}
        }
    },
    "går": {
        "sin": {
            "vante": {
                "gang": {}
            }
        }
    },

Here is a tree where "alt" is the root, the idioms "alt er bare fryd og gammen", "alt er klappet og klart", "alt er såre vel" and "alt går sin vante gang" can be found by traversing the tree.
These trees can be found at all_idioms_sequence_graph.json, nno_idioms_sequence_graph.json and nob_idioms_sequence_graph.json.

Flat versions of the trees (where consecutive nodes/words with only one child are merged into word sequences) can be found at all_idioms_flat_sequence_graph.json, nno_idioms_flat_sequence_graph.json and nob_idioms_flat_sequence_graph.json.
Example:

"alt": {
    "er": {
        "bare fryd og gammen": "",
        "klappet og klart": "",
        "såre vel": ""
    },
    "går sin vante gang": "",
