Overview / Open Energy Ontology / Class - data set

Label: data set

Definition:

A data item that is an aggregate of other data items of the same type that have something in common. Averages and distributions can be determined for data sets.

Editor note:

2009/10/23 Alan Ruttenberg. The intention is that this term represent collections of like data. So this isn't for, e.g. the whole contents of a cel file, which includes parameters, metadata etc. This is more like java arrays of a certain rather specific type

Editor note:

2014-05-05: Data sets are aggregates and thus must include two or more data items. We have chosen not to add logical axioms to make this restriction.

Sub classes:

empirical data set

view

Definition:

An empirical data set is a dataset that is obtained from observations in the real world.

energy balance collection

view

Definition:

An energy balance collection is a data set of energy balances for various time steps and/or temporal regions.

synthetic data set

view

Definition:

A synthetic data set is a dataset that is obtained by artificially creating data items. It is constructed to be an estimation of a real-world dataset.

test data set

view

Definition:

A test data set is a data set used for testing.

time series

view

Definition:

A time series is a data set that references to a set of time steps or zero-dimensional temporal regions.

Back to the super classes:

data item

view

Definition:

A data item is an information content entity that is intended to be a truthful statement about something (modulo, e.g., measurement precision or other systematic errors) and is constructed/acquired by a method which reliably tends to produce (approximately) truthful statements.

Editor note:

2/2/2009 Alan and Bjoern discussing FACS run output data. This is a data item because it is about the cell population. Each element records an event and is typically further composed a set of measurment data items that record the fluorescent intensity stimulated by one of the lasers.

Editor note:

2009-03-16: data item deliberatly ambiguous: we merged data set and datum to be one entity, not knowing how to define singular versus plural. So data item is more general than datum.

Editor note:

2009-03-16: removed datum as alternative term as datum specifically refers to singular form, and is thus not an exact synonym.

Editor note:

JAR: datum -- well, this will be very tricky to define, but maybe some information-like stuff that might be put into a computer and that is meant, by someone, to denote and/or to be interpreted by some process... I would include lists, tables, sentences... I think I might defer to Barry, or to Brian Cantwell Smith JAR: A data item is an approximately justified approximately true approximate belief
