title: The Cognitive Task Ontology (CogiTO)

description: The aim of COGITO is to relate Tasks from Cognitive Atlas to HED tags. In other words, we define the terms for cognitive tasks by their relation to HED tags, e.g. Reading Task is equivalent to (has some Language-item) AND (has some Read), where Reading Task is a Task from Cognitive Atlas and {Read, Language-item} are HED Tags. The purpose of this ontology is to query partially annotated datasets either by a Cognitive Task or by HED tags.

Usage

In order to use CogiTO following these steps:



Download or Clone this respository

Open the cogito.owl file with an OWL-compliant editor, such as Protégé.

Check Imports: we reuse existing OWL files from Cognitive Atlas and HED by an OWL import. Sometimes the import fails, in which case it is necessary to reimport the ontologies.

Enable ELK Reasoner in Protégé (recommended for reasoning, as other reasoners may time out due to ontology complexity): go to Window → Reasoner → ELK


LLM Assistant

To generate the mapping between Cognitive Atlas tasks (based on their natural language description) and the corresponding HED tags, we eployed a LLM (Gemini 2.5 Pro). The selection of Gemini 2.5 Pro was based on an evaluation of several LLMs (see llm-assistent/). Specifically, we compared the LLM-generated HED tag sets with expert annotations for 10 representative Cognitive Atlas tasks using the Jaccard similarity coefficient as a performance metric. We chose the following 10 tasks for the evaluation: Stroop task, Semantic decision task, Overt word repetition, Naming covert, Emotion recognition task, Tone counting, Associative memory encoding task, Dual-task weather prediction, Lexical decision task, Oddball task. For the expert annotations see human_annotation.csv.

Evaluation

In evaluation/ we implemented five different OWL reasoner all supporting the OWL 2 EL profile. To execute each of the reasoners just execute ./evaluate.sh (it might be necessary to execute chmod +x evaluate.sh first). The reasoners output an OWL file including the inferred facts (<reasoner>_inferred_output.owl). In the evaluation script a timeout is set to 1200s, since all reasoners - besides the ELK reasoner - time out.

Queries

In queries/ we provide some generated test queries in CRPQ syntax for testing. The queries can be divided into five group of queries:

G1 - querying for datasets that have a path to a certain taskG2 - querying for datasets that have a path to a certain HED tagG3 - querying for datasets that have paths to two HED tagsG4 - querying for a certain HED tagG5 - querying for a certain task

Data

The ontology file itself (ontologies/cogito.owl) contains a set of example individuals to demonstrate the use of the Protégé build-in reasoners. However, in theory each BIDS formatted dataset provides potential instances to CogiTO. The RDF data contain the meta-data from OpenNeuro datasets, which we exported by the so-called BIDS Indexer (Research Edition).

title: CO2 NEE, ER and GPP + air and soil meteorological and climate parameters in Arctic tundra, Ny Ålesund (Svalbard, NO) - summer 2019_and 2021-2025 – single point measurements

description: The dataset “CO2 NEE, ER and GPP + air and soil meteorological and climate parameters in Arctic tundra, Ny Ålesund (Svalbard, NO) - summer 2019_2021_2022_2025 – single point measurements” is a .csv file (filename: 0.data_NyAlesund_2019-2025.csv) reporting CO2 fluxes and basic meteoclimatic variables measured on vascular vegetation in the Bayelva Basin near Ny Ålesund, in the Brøgger peninsula, Spitsbergen, Norway, during the 2019, 2021, 2022, 2023, 2024 and 2025 growing season peaks (about end of July-beginning of August).

Data have been measured at two sites, called AIRPORT and CZ (Critical Zone Observatory). Average coordinates of the measuring sites are: AIRPORT: 78°55’25.7” N, 11°53’29.4” E; CZ: 78°55'15'' N, 11°51'25 E (WGS84). Fluxes were measured using the flux chamber method: the Net Ecosystem Exchange (NEE) was measured with a transparent flux chamber, while the Ecosystem Respiration (ER) with a shaded chamber. Gross Primary Productivity (GPP) is calculated as GPP = NEE - ER, where GPP is always negative, ER is always positive, and NEE can be either positive or negative or null according to the prevailing process. Sampling was performed in points covered with a mix of the most common vascular plants species at the measuring sites (Dryas octopetala, Silene acaulis, Salix polaris, Saxifraga oppositifolia, Carex rupestris or other Carex spp) and non vascular species (mainly lichens and biocrust, very sparse moss as the site is a dry tundra).

Measurement units used in the dataset: Fluxes (NEE, ER and GPP) are expressed as (μmol/m2/s).

Flux data are complemented by measurements of solar irradiance (Rad , in W/m2), air temperature (Ta, in Celsius degrees), air moisture (RH, in %), soil volumetric water content (VWC, in %), soil temperature (Ts, in Celsius degrees), Green Fractional Cover (GFC, fractional number between 0 and 1), WGS84 Coordinates (lon and lat, degrees.decimal degrees), Day of the Year (doy, integer number), Snow Melt-Out Day from MODIS data (smod, integer number), Days Since Snowmelt (DSS_rs, integer number) calculated as doy-smod. The Green Fractional Cover of the vegetation inscribed within the sampling surface was estimated from digital RGB pictures taken at the nadir of the measurement points.  Date of measurement is expressed in dd.mm.yy, and time of measurement as hour.decimal-hour.

Please note that the older version of this dataset (filename: 0.data_NyAlesund_2019-2023.csv, version V1 (DOI: 10.5281/zenodo.13284501) is a subset of this dataset, containing only data from vascular vegetation and from the years 2019-2023 and with DSS calculated from data acquired from the climate station “Ny-ålesund, SVALBARD (SN99910)” from the website https://seklima.met.no/ of the Norwegian Centre for Climate Services.
