The ability of computer systems or software to exchange
and make use of information -
....ANSWER...Interoperability
Where information is distributed
... [Show More] across a large number of
aggregators (IoT platforms), it is necessary to first identify
which aggregators contain information of interest and
afterwards find specific data sets - ....ANSWER...Discovery
In the more open environment of the IoT, a provider of
information generally does not know all potential consumers
of its data. Facilities that allow information providers to
retain control over access should therefore be provided by
an IoT platform. - ....ANSWER...Access control
The primary aim of the ____ ______ platform is to reduce
the technical barriers faced by both providers and consumers
of information in which they have a shared interest. -
....ANSWER...Data access
Set of data that describes and presents information about
other data. Metadata is a child set of data provided within an
initial query of parent data - ....ANSWER...Metadata
Key-value pair of data that is relational to the initial query of
data from a sensor - ....ANSWER...Dataset
This is closely related to the sensor data type, grouping sets
of measurements appropriately. Representing the track
followed by a bus or bicycle is an example of this. -
....ANSWER...Journeys
Represented as geospatial features (e.g., point, line, or
polygon) with arbitrary associated properties described in
metadata - ....ANSWER...Geographical features
Includes an aggregation of sensor-based data and other data,
as well as interpretation. It is relevant to a time period and
some specified locations - ....ANSWER...Situations
Process that accumulates new data into disjunctive groups
and processes them at a later time, which is defined by
criteria such as size or age - ....ANSWER...Batch processing
Set of operations that can be done on the data to reduce the
occupied space for storing and/or the required bandwidth for
transmitting - ....ANSWER...Compression
Set of techniques that reduce the number of random
variables (or dimensions) under consideration -
....ANSWER...Dimensionality reduction
Process of transforming the data in order to provide to the
human and machine data consumers a representation that
best describes the time series under consideration -
....ANSWER...Summarization
Learning refers to methods that automate model building
from recorded data.
Mining involves using models to extract insights and
understand large datasets that are otherwise impossible to
analyze - ....ANSWER...Learning and mining
Methods that transform the data into a visual representation
targeted at a human consumer - ....ANSWER...Visualization
2nd generation stream processing system that utilizes
automated scaling - ....ANSWER...Flink
Supports both stream and batch functionalities, provides
both accurate and up-to-date, near-real-time results -
....ANSWER...Lambda architecture
batch - ....ANSWER...In Kappa architecture, the
__________ layer is not present and all data are processed
exclusively as streams
Important for sensing what is happening in the radio
frequency electromagnetic spectrum, with relatively low
cost sensors - ....ANSWER...Stream analytics
Streaming architecture and an open source library used to
ingest time, frequency, and energy values of data in real
time - ....ANSWER...Spectrum Streamer
Detected transmissions that can be used to update spectrum
occupancy databases or directly notify other devices that a
transmission is happening in a certain channel -
....ANSWER...Real-time notifications
References a report delivered by computational statistics of
the detected events, primarily targeting human users for
report generation - ....ANSWER...Statistical reporting
Performance measure used to evaluate the efficiency or
profitability of an investment or to compare the efficiency of
a number of different investments - ....ANSWER...Return on
Investment (ROI) [Show Less]
