Big Data

Big data is not just “great volumes of data”

Big data implicates data collection, data organization, data context, data flow, and data application, data analysis

Data ecosystem Data providers (persons, teams, and organizations)

Information systems for data curation

Infrastructures for data dissemination

Researchers and experts for data processing

Algorithms for data analysis and visualization

Data applications for general purposes

Data consumers (persons, teams, and organizations)

Libraries’ Efforts towards e-Research

Start from institutional repository to research

data repository

Focus on data curation with supports of policies

and strategies

Collaborate with office of research and

development

Make efforts from institutional level to national

level

Data Curation

Data

Raw data, created data, output data, etc.

Curation means "care for"

Research data has to be collected and

managed carefully for later access and reuse

Data curation is to maintain, preserve, and add

value to research data and to construct reliable

digital repository for current and future use

e-Research vs. Data Curation

Data curation could be regarded as one of

components in the e-Research framework

Data curation is the answer to storage and

management of research data in e-Research

In addition, data curation could be the hub to

connect to other components of e-Research

Why Data Curation is Important

Data deluge

Sensor-generated data, model-generated data, user-

generated data, etc.

Data loss

Characteristics of digital data, scholars' behaviors, no

preservation strategies, etc.

Data effectiveness

Insight, verification, innovation, etc.

Niche for Academic Libraries

towards Data Curation

Libraries have long and good experiences in

acquisition for final products of researches,

although there were few efforts in acquisition for

research data

Librarians are professionals of data organization,

information access, collection management,

and institutional repository

Librarians will be experienced data experts

Before submitting data to curation systems, data

should be re-organized.

No time to participate activities of data curation

Willing to use data curation system as one of

backup mechanisms
