  This paper presents two colloquial Sinhala language corpora from the language
efforts of the Data, Analysis and Policy team of LIRNEasia, as well as a list
of algorithmically derived stopwords. The larger of the two corpora spans 2010
to 2020 and contains 28,825,820 to 29,549,672 words of multilingual text posted
by 533 Sri Lankan Facebook pages, including politics, media, celebrities, and
other categories; the smaller corpus amounts to 5,402,76 words of only Sinhala
text extracted from the larger. Both corpora have markers for their date of
creation, page of origin, and content type.
