Data set Contents
The dataset consists of a .zip folder, named non-deviation_dataset.zip, containing two subsets and one README file:
• “non-deviation_subset1_NN_reduplication.xlsx/.csv”, 2 tabular files saved in both .xlsx and .csv format
• “non-deviation_subset2_N-tipo.xlsx/.csv”, 2 tabular files saved in both .xlsx and .csv format
• “non-deviation_READMEfile.rtf”, text file saved in .rtf format
Abstract
The dataset consists of two subsets and one README file. The two subsets were collected and annotated following the same methodological principles in order to compare two Italian constructions expressing meanings related to category centrality or prototypicality, namely the NN reduplication construction (e.g., caffè-caffè ‘real/prototypical coffee’) and the N-tipo construction (e.g., giornata tipo ‘typical day’). The data come from the CORIS corpus (2021 version): https://corpora.ficlit.unibo.it/coris_ita.html. 

Content of the files
• files “non-deviation_subset1_NN_reduplication.xlsx/.csv” contain attested instances of the Italian NN reduplication construction extracted from the CORIS corpus 
• files “non-deviation_subset2_N-tipo.xlsx/.csv” contains attested instances of the Italian N-tipo construction extracted from the CORIS corpus
Data sources
The data come from the CORIS corpus (2021 version): https://corpora.ficlit.unibo.it/coris_ita.html 
Methodology
As for subset1 (NN reduplication), all sequences of two identical nouns (with or without a hyphen) were extracted from CORIS, then manually checked, and annotated for subcorpus (automatic), lemma, hyphenation, POS, number, and ontological class. The final subset includes 95 instances of NN reduplication expressing meanings related to prototypicality and category centrality.
As for subset2 (N-tipo), all occurrences of the N-tipo construction containing a hyphen between the noun and tipo were extracted from CORIS, then manually checked, and annotated for subcorpus (automatic), lemma, hyphenation (the hyphen is always present in this subset, but the feature was maintained in view of future subset expansions), POS, number, and ontological class. The final subset includes 183 instances of the N-tipo construction expressing meanings related to canonicity and stereotypicality.
File specifics
The .csv files have the following specifics:
•	Character set Unicode (UTF-8)
•	Field delimiter « ; » (semicolon)

List of variables

List of features and values for the annotation of subset1:
•	Subcorpus: CORIS subcorpus and section (as documented here https://corpora.ficlit.unibo.it/coris_engDesign.html) in which the example is found
•	Left: left context
•	KWIC: keyword in context
•	Right: right context
•	red_form: reduplicated form
•	red_lemma: lemma of the reduplicated noun
•	hyphen: yes, no
•	red_POS: NN (common noun), NN_P (proper noun)
•	number: sg (singular), pl (plural)
•	onto_class: ontological class (abstract, art_&_communication, concrete_inanimate, event, human, organization, place)

List of features and values for the annotation of subset2:
•	Subcorpus: CORIS subcorpus and section (as documented here https://corpora.ficlit.unibo.it/coris_engDesign.html) in which the example is found
•	Left: left context
•	KWIC: keyword in context
•	Right: right context
•	N_lemma: lemma of noun occurring before tipo
•	N_form:
•	hyphen: yes, no [always yes]
•	POS: NN (common noun), NN_P (proper noun)
•	number: sg (singular), pl (plural)
•	onto_class: ontological class (abstract, communication, concrete_inanimate, event, human, organization, time)
