2. Introduction
For academic research, you can rely on scientific
sources and websites that provide reliable data sets.
The best way to publish and share research data is
with a research data repository. A repository is an
online database that allows research data to be
preserved across time and helps others find it.

3. Introduction
 Here are some sites and engines you can use to find datasets for
academic research purposes
1. Figshare
2. Lincoln Centre for Autonomous Systems (LCAS)
3. Mendeley Data
4. Nasdaq Data Link
5. Harvard Dataverse
6. Harvard Dataverse
7. Dryad Digital Repository
8. Network Repository
When using these resources, be sure to read and understand the
terms of use of the data sets and ensure compliance with any
applicable laws or licenses.

4. figshare
figshare is a repository and a web-based interface designed
for academic research data management and research data
dissemination.
 It accepts all file types (with in-browser viewing).
The Figshare team now spans 3 continents
 Its characteristics:
1. Online open access repository
2. Data security
3. Contains figures, datasets,
images, and videos.
The website : figshare.com

 Research center based at the University of Lincoln in UK.
 Cross-Disciplinary in Robotics Research.
 Specializes in technologies for perception, learning, decision-making,
control, and interaction in autonomous systems, especially mobile robots
and robotic manipulators,
 and the integration of these capabilities in application domains including
 Agri-food,
 Healthcare,
 Intelligent transportation,
 Logistics,
 Nuclear robotics,
 Service robotics, and
 Space robotics.

The website :

14. figshare
 Open access data repository.
Datasets: images, and videos.
Figshare allows researchers to upload any file format and
assigns a digital object identifier (doi) for citations.
Free accounts on figshare can upload files of up to 5gb and
get 20gb of free storage.
fields:
Software and Code
Models and Simulations
Machine Learning and Data Science
The website : https://figshare.com/

16. Harvard Dataverse
 The harvard dataverse repository is a free data repository open
to all researchers from any discipline, both inside and outside of
the harvard community,
 Can share, archive, cite, access, and explore research data.
 You can open your data to the general public, or restrict access
and define customizable terms of use. When you publish your
data, you automatically get a standard data citation with a
digital object identifier (DOI).
 Powered by the open-source web application dataverse,
developed by the insitute of quantitative social science at
harvard.
 Is free and has a limit of 2.5 GB per file and 10 GB per dataset.

18. Dryad Digital Repository
Dryad is a curated general-purpose repository that
makes data discoverable, freely reusable, and citable.
Most types of files can be submitted (e.g., text,
spreadsheets, video, photographs, software code)
including compressed archives of multiple files.
Since a guiding principle of Dryad is to make its
contents freely available for research and educational
use, there are no access costs for individual users or
institutions. Instead, Dryad supports its operation by
charging a $120US fee each time data is published.

20. Network Repository
The first interactive data and network data repository with real-time
visual analytics. Network repository is not only the first interactive
repository, but also the largest network repository with thousands of
donations in 30+ domains (from biological to social network
data). This large comprehensive collection of network graph data is
useful for making significant research findings as well as benchmark
network data sets for a wide variety of applications and domains
(e.g., network science, bioinformatics, machine learning, data
mining, physics, and social science) and includes relational,
attributed, heterogeneous, streaming, spatial, and time series
network data as well as non-relational machine learning data. All
graph data sets are easily downloaded into a standard consistent
format. We also have built a multi-level interactive graph analytics
engine that allows users to visualize the structure of the network data
as well as macro-level graph data statistics as well as important
micro-level network properties of the nodes and edges.
Check out GraphVis: the interactive visual network mining and
machine learning tool.
