Hypotheses No criterion is sufficient by itself Each criterion yields different measures of

internationality Some criteria are difficult to quantify In the absence of a multi-criteria, single-valued

index, internationality remains a highly subjective and ambiguous estimate based on a biased choice of evaluation criteria

Internationality Assessment

Conclusion Journal Internationality cannot be

measured unambiguously by the assessment of individual criteria

Need for a multi-criteria, single-valued Journal Internationality Index

A neuro-fuzzy system to calculate the Journal Internationality Index (JII)

Internationality Index = f {criteria}

How do we find this function?

With the new JII we will be able to:

Quantitatively measure internationality Qualitatively define Internationality Re-assess academic journals
