    • Q: What is the criteria for an entry with high quality?
      A: Generally, the elements of a high-quality entry are as follows: a short title, concise definition, comprehensive and objective content, appropriate reference citations, and no copyright conflict. Title: It should be a noun or noun phrase within 5 words. If the item has more than one appellation, it is better to use the academic or the official one as the title. We encourage using the full name of the item as the entry title, unless the abbreviation is common. If the title is a countable noun, it should be in the singular form. Definition: It should focus on the most essential part. If possible, it should start with “{Title} is …”. The definition should be a single paragraph without any citations. Content: It should be clearly structured and begin with “Introduction”. We encourage you to include all the research aspects of this topic in as much detail as possible. Besides this, the content should have been validated, and we do not encourage the inclusion of new, unreported findings in Encyclopedia. Appropriate reference citations and no copyright conflict are required. For more details on the copyright issue, please refer to the related explanation in “Help”. Others: Figures: The entry is better with figures. Figures should be high-resolution to make sure readers can easily read the smallest font size of a character, number or symbol on it. Format: The structural sections should be preceded by headings. They should be in sequential numerical order: “heading 1”, then “heading 2, heading 3…” in the same section. It is better to insert the references via our editing tool to make sure they are correctly formatted and without duplication.

    • Q: What is the difference between “Abstract” and “Definition”?
      A: An Abstract should be a brief and objective summary of the whole entry, usually presented in one paragraph, without headings and references. On the Encyclopedia platform, the entry types “Biography” and “Video” require an Abstract. For “Biography”, the Abstract should be a short introduction of the personal career and experience within 2–5 sentences. When it comes to the “Video”, the Abstract should be a brief representation of the video content. The Definition should be a statement of the meaning of a term (a word, phrase, or other set of symbols, usually referring to the title of the entry). It should be limited to the most essential and important aspects of the entry. On the Encyclopedia platform, the entry type “Topic Review” has a Definition part that usually starts with “Title is…”. For example, Chitosan is a random copolymer comprising d-glucosamine (the deacetylated ones) and N-acetyl-d-glucosamine units.
