DisArticle provides three main menus. Each menu can be used in the following manner for different functions.

1. Distinction
When a user inputs the PMID of an article on the MEDLINE database or the metadata of an article, this menu can determine whether that article pertains to traditional medicine. This evaluation is conducted using the SVM-based classifier model (TAK-HM) built in our study.

* Distinguishing articles by using a single PMID
(1) Enter one PMID in the search field in the upper area of the PMID tab and then click the “Distinct” button.
(2) The distinction results are shown in the bottom area. Below this area, the title, affiliation of the author(s), journal title, publication date, abstract, and MeSH of the article are also provided, enabling users to confirm the results.

* Distinguishing articles by using their metadata
(1) Enter the article’s title, abstract, affiliation of the author(s), journal title, and MeSH in the metadata tab and then click the “Distinct” button. The input of the title and abstract of an article is mandatory.
(2) The distinction results are shown based on the input data. Below these results, the metadata entered is also provided, enabling users to confirm the results.

* Distinguishing multiple articles
(1) The following API provided on this server can be called out to obtain the distinction results. Distinguishing multiple articles is only possible for articles on the MEDLINE database with PMID.
- URL: http://informatics.kiom.re.kr/disarticle/query.do
- Input: At least one PMID, separated with a comma.
- Output: List of JSON-type PMID and distinction result
(2) Calling examples
- query: http://informatics.kiom.re.kr/disarticle/query.do?id=22105022,22105023,22105024
- result: {"status":"success","result":{"22105024":"x","22105023":"x","22105022":"x"}}
2. Search
DisArticle has identified whether articles registered to the MEDLINE database by January 8, 2016, are related to traditional medicine. This menu allows users to search the articles identified as those belonging to traditional medicine.

(1) If the “Search” menu is clicked, an exclusive list of around 108,000 articles identified as being in the field of traditional medicine is shown.
(2) The list of articles is arranged in the reverse order of the PMID, and the set of article information contains the title, journal title, publication date, and PMID. When users click one article, a new pop-up window connected to Pubmed showing detailed information about the article is shown.
(3) Click the “Chart” tab to see the same list of articles as a bar chart. Here, the horizontal axis has the published years, and the vertical indicates the number of articles published in the relevant year. If users drag a part of the chart with the mouse, they can see an enlarged image. Also, the “reset zoom” button on the upper right side will direct the users back to the first search result.
(4) If users click the bar for a specific year, a list of articles published in the relevant year is shown in a pop-up window
(5) Enter a keyword in the upper search field and click the “Search” button, and the articles matching the keyword appear from among the articles identified as those belonging to traditional medicine. This search uses a search engine called Apache Lucene. The methods of looking at the search results are the same in (2) through (4).
3. Statistics
This menu provides data of “Top ten ranked herbs” and “Top ten ranked journals” for articles identified as those in traditional medicine. The number of statistical data provided is kept to ten because of the limited screen size and search speed.

(1) Click the “Herb” tab to see the “Top ten ranked herbs” as a stacked bar chart.
(2) The X axis has the year of publication, while the Y axis has the number of articles published for the ten herbs in the relevant year. On the upper left the legend for the chart about ten herbs is provided.
(3) When users click any of the herbs in a specific bar, the list of related articles will appear in a pop-up window.
(4) The list of articles is arranged in the reverse order of the PMID, and the set of article information contains the title, journal title, publication date, and PMID. When users click one article, a new pop-up window connected to Pubmed showing detailed information about the article is shown.
(5) By clicking the “Journal” tab, users can see the “Top ten ranked journals” in a stacked bar chart, and the methods of looking at the search results are the same in (2) through (4).
