Systems - Quality of Papers

International Standards

There isn't a single international system for ranking academic publications that is universally recognized or adopted. However, there are a few prominent systems and metrics used worldwide to assess the quality and impact of academic publications. Here are some of the well-known international systems:

1. Journal Impact Factor (JIF): The Journal Impact Factor is calculated by Clarivate Analytics (formerly Thomson Reuters) and is based on the average number of citations received by articles published in a particular journal within a specific time frame. Journals with higher impact factors are generally considered to be more influential and prestigious.

2. Scopus: Scopus is an abstract and citation database maintained by Elsevier. It provides a range of metrics to evaluate scholarly journals, including the CiteScore, which measures the average citations per document over a three-year period. Scopus also offers other metrics like SJR (SCImago Journal Rank) and SNIP (Source Normalized Impact per Paper).

3. Web of Science: Web of Science, also operated by Clarivate Analytics, is another widely used citation database. It offers metrics such as the Impact Factor, Eigenfactor Score, and Article Influence Score to evaluate journals based on citation data.

4. H-index: The h-index is an author-level metric that aims to measure both the productivity and impact of a researcher's publications. It considers the number of papers a researcher has published and the number of citations those papers have received. The h-index is often used alongside other metrics to assess a researcher's academic influence.

It's important to note that these systems have their limitations and may not provide a comprehensive assessment of research quality and impact. Different fields of study may have their own specific ranking systems or metrics. Additionally, qualitative factors such as the novelty, originality, and significance of research are not captured by these metrics alone. Therefore, it's advisable to consider multiple indicators and evaluations when assessing the quality and impact of academic publications on an international scale.

Thai Standards

The TCI system, also known as the Thailand Citation Index, is a ranking system used in Thailand to assess the quality and impact of academic publications. It is primarily employed by the Thailand Research Fund (TRF) and the Office of Higher Education Commission (OHEC) to evaluate the research output of Thai universities and researchers.

The TCI system focuses on scholarly journals and assigns a ranking to them based on their quality and citation impact. The ranking is divided into three tiers: TCI Tier 1, TCI Tier 2, and TCI Tier 3.

1. TCI Tier 1: This tier comprises high-quality journals with significant academic impact. Journals in this tier generally have a rigorous peer-review process, publish influential research, and attract a wide readership. Publications in TCI Tier 1 journals are highly regarded and contribute significantly to a researcher's academic reputation.

2. TCI Tier 2: Journals in this tier are considered to be of good quality and have a moderate academic impact. While they may not have the same level of prestige and impact as TCI Tier 1 journals, they still maintain a solid standard of scholarship and contribute to the academic community.

3. TCI Tier 3: This tier includes journals with a lower level of quality and impact compared to Tier 1 and Tier 2. Publications in Tier 3 journals are generally considered to have limited academic value and may have less rigorous peer-review processes. However, it is important to note that not all journals in Tier 3 are of poor quality; some may be regionally focused or cover specialized topics.

The TCI ranking is based on various criteria, including the journal's reputation, citation metrics, peer-review process, editorial standards, and international visibility. The TCI system helps researchers, institutions, and funding agencies in Thailand assess the quality and impact of academic publications and make informed decisions regarding research funding, promotion, and academic recognition.

It is worth mentioning that the TCI system is specific to Thailand and has its own criteria and methodology. Other countries and regions may have their own ranking systems, such as the Journal Citation Reports (JCR) in the United States or the European Reference Index for the Humanities (ERIH) in Europe, which serve similar purposes but may employ different approaches and metrics.
