dhlab 2.0.22

Library for text and image analysis by the Digital Humanities lab (DH-lab)

DHLAB

dhlab is a python library for accessing reduced representations of text and pictures at the National Library of Norway (NLN), Nasjonalbiblioteket (NB) in Norwegian. It is developed and maintained by The Digital Humanities lab group.

The python package includes wrapper functions for the API (Application Programming Interface) that can be used to query the texts in NB Digital, the NLN's digital collection of books and newspapers.

The API allows for textual qualitative and quantitative analyses of the digital texts by generating e.g. word frequency lists, concordances, collocations, n-grams, as well as extracting names and narrative graphs.

Analyses can be performed on both a single document, and on a larger corpus. It is also possible to build one's own corpora based on bibliographic metadata.

The Jupyter Notebooks in the digital_tekstanalyse repo show examples on how to use the library, and can be used directly in your browser without prior programming experience.

Installation

Install dhlab in your terminal with pip:

pip install dhlab

Example use

You could start by building your own corpus, e.g. of books published between 1814 and 1905:

from dhlab.text import Corpus

book_corpus = Corpus(doctype="digibok", from_year=1814, to_year=1905)
