The Most Frequently Asked Question by a Researcher

Dju-Lyn CHNG Solution Consultant (Southeast Asia) [email protected]

October 2018

How do I get published? Which journal should I publish in?

3

WHERE you publish is the most important factor to determine if your paper gets cited

“For the literature as a whole — 39 million research papers across all disciplines recorded in the Web of Science from 1900 to the end of 2015 — some 21% haven’t yet been cited. Unsurprisingly, most of these uncited papers appear in littleknown journals; almost all papers in well-known journals do get cited”

Some Viable Publishing Strategies

Strategy

How?

“I look for government accredited journals”

Refer to Malaysian Citation Index published by MOHE

“I look for internationally recognized journals.”

Use Web of Science or JCR to find high quality international journals

“I want to publish in journals with high rank and prestige”

Find journal ranking and quartiles in JCR

“I aim for journals that get cited very quickly” “I want to publish in journals that gets cited for a long time”

Use “Immediacy Index” metric in JCR Use “Cited Half Life” metric in JCR

What is the JCR? The JCR is an annual report that distills citation trend data from the Web of Science Core Collection to help you understand journal performance. •

View Journal Impact Factor and other metrics.

•

Data represents a snapshot in time: the 2018 edition reflects citations from literature published in 2017.

•

All journals in JCR are sourced from two indexes: ̶ Science Citation Index Expanded ̶ Social Sciences Citation Index

•

Citations are sourced from all indexes in the Core Collection. ̶ New in 2018: Citations from the Book Citation Index content contribute to Journal Impact Factor numerators.

But… Why use Journal Citation Reports?

Why use the JCR? Publishers/Editors • Compare your journals directly against peers and competitors. • Understand the citation profile of the documents in your journals. • Track your publications’ performance by building a custom journal list. Librarians • Find quantitative data to justify your collection development decisions. • Evaluate your collections with custom journal lists. • Track your faculty/institution’s contributions to journal performance. Data Scientists • Dive deeper into the JCR data with our downloadable cited and citing data tables, as well as the full data and metrics files, to understand how disciplines interconnect in the citation network. Researchers • Evaluate journals for your submissions. • Focus on publishing trends like Open Access • Determine your articles’ contributions to journal performance.

Journal Citation Reports provides NEUTRAL and OBJECTIVE Journal Measurements

“Clarivate Analytics is neutral: we are not a publisher and we have no plans to become one.” What this means: Clarivate doesn’t own journals, they are an information company. This makes JCR rankings objective and unbiased. “We carefully weed out any predatory and non-peer-reviewed journals, so you can be confident that only the best journals are eligible to be given a JIF score.” What this means: Impact Factor is precious and ONLY THE BEST journals receive one. https://clarivate.com/blog/science-research-connect/research-management/citescore-a-non-rival-for-the-journal-impact-factor/

Journal Impact Factor is Proprietary to Clarivate

Every journal has a story to tell – JCR tells it

The Journal Impact Factor is a very useful tool for evaluation of journals, but it must be used carefully. At its core, the Journal Impact Factor is used to compare different journals within a certain field, bearing in mind considerations including the amount of review or other types of material published in a journal, variations between disciplines, and item-by-item impact.

• •

1963, Eugene Garfield launches Science Citation Index, ISI, Philadelphia Garfield develops concept of Citation Indexing for research discovery

• •

The Impact Factor was developed to help select journals for SCI Available in 1975

Using Journal Impact Factor Scores as a measure (or proxy) of performance for individual papers or authors represents IMPROPER USE of the metric in research evaluation.

Journal Citation Reports

“I aim for journals that get cited very quickly”

35

JIF is not the only metric for journal ranking

Remove selfcitations for deeper understanding

Are materials in this journal quickly cited?

The age of citing / cited materials

Is this journal cited by influential journals?

Clarivate Analytics stance on metrics: Always use multiple metrics for a thorough understanding!

How is this journal ranked compared to others in the same field?

Immediacy Index is also understood to be “1 year Impact Factor”

Cited Half-Life is an important Metric!

Note: Metrics such as Impact Factor is useful but they DO NOT replace human expertise.

Bonus! How do you find related journals quickly?

Journal Relationships show you how journals interact

In this example, you can see journals related to Malaysian Journal of Computer Science. Librarians use this for collection management. Researchers use this to find related journals to submit their work.

Journal self-Citations and other citation anomalies

46

Self-citations are items citing another item in the same journal

Journal A

This counts of 3 journal self-citations for Journal A

Journal B

This counts as a citation to Journal B.

JCR Quiz - True/False questions

JCR contains many journal metrics for various publishing strategies True! No single metric is perfect. Depending on what your publishing strategy is, JCR has different metrics to assist in your decision making process. JCR covers Science, Social Sciences and Arts & Humanities journals.

False! JCR does not cover Arts & Humanities journals as citation analysis is less useful in those subjects.

JCR Quiz - True/False questions

Clarivate Analytics invents new journal metrics to make their own journals look better than competing journals. False! Clarivate does not own any journals and is neutral in its metric calculation methods.

Clarivate Analytics take serious actions against citation manipulation True! Clarivate monitors its database and is the ONLY database provider that has a history of annual deselections.
