Maltese News Categories

A multi-label topic classification dataset for Maltese News Articles.

Data Collection

The data was collected from the press_mt subset from Korpus Malti v4.0. Article contents were cleaned to filter out JavaScript, CSS, & repeated non-Maltese sub-headings. The labels are based on the category field from this corpus. Additional filtering & cleaning was performed as follows:

Documents with generic categories (News, Local, Headlines, Uncategorised, Archived) were ignored.
Some categories were merged as deemed necessary by native Maltese speakers to standardise tags assigned by different news portals (for example merging European Union & Unjoni Ewropea under EU).
Articles with categories having less than 100 articles were ignored.
Categories having a >75% co-occurence with another category are dropped.

The different tags & their distribution is shown in the following table.

Tag	Token Count	Article Count	Article Percentage

Covid	458,120	1,735	11.29
