Data are one part of scholarly capital, along with human capital and instrumentation. Data have become essential scholarly objects to be captured, mined, used and reused. Research in all academic fields relies on data.

Definitions associated with archival information systems offer a useful starting point:

Definition of data

A reinterpretable representation of information in a formalized manner suitable

for communication, interpretation, or processing.

Examples of data include a sequence of bits, a table of numbers, the characters on a page, the recording of sounds made by a person speaking, or a moon rock specimen.

Definition of data

In Buckland’s terms, data are

“alleged evidence”

Socio-technical definition

Page 7: What are Data?

What are data? Think about data by its origin.

In the context of cyberinfrastructure, the four categories of data identified in an influential U.S. policy report Long-lived Data Collections 2005, and incorporated in National Science Foundation strategy Cyberinfrastructure Vision for 21st Century Discovery 2007, are now widely accepted.

1. Observational data- include weather measurements and attitude surveys...

2. Computational data- result from executing a computer model or simulation whether for physics or cultural virtual reality.

3. Experimental data- include results from laboratory studies such as measurements of chemical reactions …

4. Records of government, business and public and private life yield useful data for scientific, social scientific, and humanistic research.

Data Variety

To give you a better idea of what can be data, Christine Borgman later expands on her examples and sources of data and how they vary by branch of research.

Exercise

Page 13: What are Data?

1. Form a group based on subject or discipline.

[Those without subject role can join in any group]

2. Hands-on exercise for Librarians (please work in group)

- use OneSearch/ Databases/ DR-NTU/ Google to get an article published by

any of your faculty or researcher.

- quickly go through the research paper, particularly the methodology section.

3. Librarians among the group to ask and answer the following questions.

[see next slide]

4. Post the findings (title of the research article, question and answer) to PD blog.

Instructions:

Page 14: What are Data?

1. Who are they? What research community do they belong to? What larger discipline is that community a part of?

2. What data are they creating (i.e., data types, formats, etc)? How are they creating these data?

3. What are the roles of data in their research?

Page 16: What are Data?

1. Who are they? What research community do they belong to? What larger discipline is that community a part of? Dianne Cmor and Victoria Marshall. Library science research community. Information Science.

2. What data are they creating (i.e., data types, formats, etc)? How are they creating these data? 1. Diary entries 2. Qualitative data from Ethnograph and SPSS 3. Reftracker report 4. Interview notes 5. Survey feedback The data are mostly text and numeric social scientific and humanities & arts data. 3. What are the roles of data in their research? The information collected was converted/ translated into data. The researchers analysed the data and got the findings out from the data. They examined and evaluated the outcomes/ findings and then built a convincing evidence to answer all the questions they have posed earlier for their research.

Example: [Before the interview]

Page 17: What are Data?

Who are they? What research community do they belong to? What larger discipline is that community a part of? Dianne Cmor is the lead researcher for a research project. Victoria Marshall is another member of the research project. Dianne and Victoria are both librarian in a university library. The project is a library related research and the topic of her research is "Librarian class attendance: methods, outcomes and opportunities". [Library science research community] The discipline of the research project belongs to Information Science.

What data are they creating (i.e., data types, formats, etc)? How are they creating these data? The researchers attended a number of seminars called “Journal club” for about 9 weeks. They have jotted down all their observation in the seminar on a diary. The diary entries were typed out in MS Word and eventually converted to some qualitative data by using the Ethnograph software and SPSS software. Reftracker was used each week to document time spent and associated outcomes in relation to meetings with students, students’ attendance, and the creation of course support content. The researchers conducted a few interview with the students and faculty members to collect information. A paper survey form was also created to collect feedback from the students and some faculty members. The researchers typed out all the notes collected from the interview and survey in MS Word. The hard copy of the diaries and survey forms were scanned and saved in PDF format. The data are mostly text and numeric social scientific and humanities & arts data. What are the roles of data in their research? The information collected through the observation at various university lectures and seminars/ tutorials, interviews and survey conducted for students and faculty members was translated into data. The team analysed the data and got the findings out from the data. They examined and evaluated the outcomes/ findings and then built a convincing evidence to answer all the questions they have posed earlier for their research.
