Research Performance Profiles• A custom-built dataset created by Thomson Reuters to match

customer specifications

• Datasets can be compiled using the following search criteria:

• Address (extracting from WOS records that contain at least one occurrence of an address e.g. Univ Manchester and variants as identified by the customer)

• Author (extracting from WOS records that contain specific authors/ or papers as identified by the customer)

• Other datasets are available for topic and journal

• Updated quarterly from date of issue. Customers can work with Incites team to request changes for better unification to improve further updates

• Incites can include source articles published between 1981 and 2012 as indexed in the Web of Science

Research Performance Profiles

RPP can be used to inform on..

• The overall performance of research at an institution

• The performance of authors

• The performance of departments

• The performance of collaborations

• The performance of areas of research

• The performance of individual papers

• The performance of papers in specific journals

• The impact/influence of published research

• The performance of papers funded by a funding agency

RPP Key Metrics• Journal Expected Citation Rate

– Average citations for records of the same type, from same journal, published in the same year

• Category Expected Citation Rate

– Average citations for records of same type, from same category, published in the same year

• Percentile in Field

– Citation performance relative to records of same document type, from same category, published in the same year. Most cited paper awarded lowest percentile (0%) and least to non-cited awarded highest percentile (100%)

• H Index

• Journal Actual/ Journal Expected

– Ratio of the actual citation count (of a paper) to the expected count of papers published in same journal, year and document type

• Category Actual/ Category Expected

– Ratio of the actual citation count (of a paper) to the expected count for papers from same category , year and document type

Page 9: InCites  TM

Global Comparisons (GC)• Global Comparisons contains aggregated comparative statistics for institutions, countries

and fields of research

• Built by Thomson Reuters. Common to all customers. All customers see the same data in GC

• Bibliographic and Citation data drawn from Web of Science

• File depth from 1981-2010

• Updated annually

• Data for Articles, Reviews and Research Notes

– Use Institutional Comparisons to compare performance of an institution or groups of institutions overall, across fields or within fields

– Institutional name variant unification (main organisation)

– Use National Comparisons to compare the performance of more than 180 countries and 9 geopolitical regions overall, across fields or within fields.

• Multiple Subject Categories

– WOS- 249 subject categories

– Essential Science Indicators – 22 broad categories

– Regional Categories (UK, Australia, Brazil)

– OECD

Page 10: InCites  TM

Global Comparison Key Metrics• Web of Science documents

• Times Cited

• Cites per document (Average Impact)

• % Documents Cited (at least 1 citation)

• Impact Relative to Subject Area (average cites of an institution in a subject area compared to the expected impact in the subject area)

• Impact Relative to Institution (average cites of papers in a field compared to the average cites overall for the institution)

• % Documents in Subject Area (market share)

• % Documents in Institution

• % Documents Cited Relative to Subject Area

• % Documents Cited to Relative to Institution

• Aggregate Performance Indicator: this metric normalises for period, document type and subject area and is a useful indicator to compare institutions of different age, size and subject focus.

10

Page 11: InCites  TM

Objective: Understand the normalised indicators and how to use them

The number of times that papers are cited is not in itself an informative indicator; citation counts need to be benchmarked or normalised against similar research. In particular: citations accumulate over time, so the year of publication needs to be taken into account; citation patterns differ greatly in different disciplines, so the field of research needs to be taken into account; and citations to review papers tend to be higher than for articles and this also needs to be taken into account.’

Source REF Pilot Study

Page 12: InCites  TM

NORMALISATION

• It is necessary to normalise absolute citation counts for:– Document type (reviews cited more than articles, some

document types cited less readily)

– Journal where published

– Year of publication (citations accumulate over time)

– Category (there is a marked difference in citation activity between categories)

• Golden rule: Compare like with like

12

Page 13: InCites  TM

Is this a high citation count?

This paper has been cited 4148 times. How does this citation count compare to the expected citation count of other articles published in the same journal, in the same year?It is necessary to normalise for:•Journal = Nature Materials•Year = 2007•Document type = article

13

Page 14: InCites  TM

Create a benchmark- the expected citations Search for papers that match the criteria

Run the Citation Report on the results page

14

Page 15: InCites  TM

Create a benchmark- the expected citations

Articles published in ‘Nature Materials’ published in 2007 have been cited on average 137.75 times. This is the Expected Count

We compare the total citations received to a paper to what is expected

4148 (Journal Actual) / 137.75 (Journal Expected) = 30.11The paper has been cited 30.11 times more than expected. We call this Journal Actual/Journal Expected

Page 16: InCites  TM

Percentile in Field. How many papers in the dataset are in the top 1%, 5% or 10% in their respective fields?

This is an example of the citation frequency distribution of a set of papers in a given category, database year and document type. The papers are ordered none/least cited on the left, moving to the highest cited papers in the set on the right. We can assign each paper to a Percentile in the set.

100% 50% 0%

In any given set, there are always few highly cited papers (top 1%)

In any given set, there are always many low cited/ none cited papers (bottom 100%)

Only document types article, note, and review are used to determine the percentile distribution, and only those same article types receive a percentile value. If a journal is classified into more than one subject area, the percentile is based on the subject area in which the paper performs the best, i.e. lowest value 16

Summary Metrics- a dashboard of indicators

Percentile Graph

For each percentile range, the “expected” number of papers (article, review & notes) in each would be equal to that same “Percentile”, meaning…

We’d expect 5% of this institutions papers to rank in the 5 th Percentile.

However, 6.79% of this institution’s papers rank in the 5th Percentile.

6.79% - 5% = 1.79%

Therefore, the number of papers this institution has placed in the top 5% of all papers published exceeds what is expected by 1.79% This 1.79% is what is presented on the graph, in Green because it exceeded the expected. Below-expected would be presented in Red

Objective: Understand the use of citation data for the 2014 Research Excellence Frame Work and how Incites may be used to inform universities on submissions

67

Page 68: InCites  TM

Research Excellence Framework 2014• Purpose: new system for assessing the quality of research in higher education institutions

in the UK

• Inform UK funding bodies allocation of grant for research (£1.76 billion for research)

• Conducted by HEFCE, SFC, HEFCW & DEL

• 36 Units of Assessment

• Process of expert review by expert panels

• Assessment criteria: 3 elements

– Output: assess quality of research output in terms of their ‘originality, significance and rigour with reference to international research quality standards. Weighting 65%

– Impact: Significant additional recognition will be given where researchers have built on excellent research to deliver demonstrable benefits to the economy, society, public policy, culture or quality of life. Weighting 20%

– Environment: asses the research environment in terms of its ‘vitality and sustainability’ including its contribution to vitality and sustainability of the wider discipline or research base. Weighting 15%

• Research outputs: details of up to FOUR research outputs produced by each member of submitted staff during publication period (1st January 2008 to 31St December 2013)

68

Page 69: InCites  TM

Use of Citation Data by Panels • Some panels to consider number of times an output has been cited and use

of appropriate benchmarks

• Expert review as primary means of assessing ‘originality, significance and rigour’

• Panels recognise limited value of citation data for

– recently published outputs (period)

– No citation data available for certain types of output

– The variable citation patterns for different fields of research

– Possibility of negative citations

– Limitations of outputs in languages other than English

– Equality implications from ‘Analysis of data from the pilot exercise to develop bibliometric indicators for the REF: The effect of using normalised citation scores for particular staff characteristics’

• Data normalised – ‘54. The number of times that papers are cited is not in itself an informative indicator;

citation counts need to be benchmarked or normalised against similar research. In particular: citations accumulate over time, so the year of publication needs to be taken into account; citation patterns differ greatly in different disciplines, so the field of research needs to be taken into account; and citations to review papers tend to be higher than for articles and this also needs to be taken into account.’

– 55. We can normalise a citation count by dividing it by the average number of citations obtained by all items included in the bibliometric database that were published in the same year of the same document type and in the same field as the item under assessment

Source of Citations

• Self citations (difficult to define and measure). Not taken into account

• Institutional citations (citations coming from same institutions as output)

• International citations received by output. Defined as number of citations from papers with at least one author associated to non-UK address

• Computed proportion of outputs in submission that were result of international collaboration

REF Pilot Study Outcomes calculated for 3 main models:

1. address based

2. submitted staff in 2008 RAE

3. selected papers for authors (limited to 6 papers with highest normalised scores)

Following indicators assessed

• the number of outputs included in the model

• the mean normalised citation score for these outputs

• the median citation score for these outputs

• the proportion of the outputs greater than twice world average

• the proportion of the outputs greater than four times world average

• the proportion of the outputs that are (as yet) uncited

• the proportion of citations to the outputs that are from the same institution

• the proportion of citations to the outputs that are from overseas

• the proportion of outputs that are an international collaboration

Using Incites in REF preparation• Use Source Article listing to inform on bibliographic details and Raw Citation Count

for papers

• Use Percentile in Subject Area to inform on publication selection (paper in top 10% or 25% of field compared to world papers in that field)

• Use Normalised Metrics (Category Actual/ Category Expected) to inform on papers with a citation impact that is twice or four times greater than the world average

• Use Category Expected indicator to inform on the normalised score for the output

• Use the Summary Metrics to inform on proportion of papers uncited (for subject area/author)

• Use the Summary Metrics to inform on Median Citation Score for selected papers

• Use Citation Impact Reports to inform on proportion of citations from oversees/ same institution for selected papers

• Use Subject Area Ranking to inform on which UOA to submit to

• Use Collaboration Reports to inform on papers that are a result of an international collaboration
