Systems, methods, and non-transitory computer-readable media can receive a plurality of comments to a posted content item. Each of the plurality of comments is associated with at least one category of a plurality of categories based on a machine learning model. A first comment of the plurality of comments is selected for inclusion in a comment sample to be presented in a graphical user interface based on the first comment being associated with a first category of the plurality of categories. A second comment of the plurality of comments is selected for inclusion in the comment sample based on the second comment being associated with a second category of the plurality of categories.

The computer-implemented method of claim 1, wherein the associating each of the plurality of comments with at least one category of the plurality of categories based on the machine learning model comprises determining, based on the machine learning model, whether a comment satisfies a neutrality score threshold indicative of neutrality with regard to the posted content item. 5. The computer-implemented method of claim 1, wherein the associating each of the plurality of comments with at least one category of the plurality of categories based on the machine learning model comprises, for each comment: determining, based on the machine learning model, whether the comment satisfies a relevance score threshold, and if the comment is determined not to satisfy the relevance score threshold, associating the comment with a non-relevance category of the plurality of categories, the non-relevance category associated with non-relevance to the posted content item, and if the comment is determined to satisfy the relevance score threshold, passing the comment to a second classification determination. 6. The computer-implemented method of claim 5, wherein the second classification determination comprises: determining, based on the machine learning model, whether the comment satisfies a neutrality score threshold, and if the comment is determined to satisfy the neutrality score threshold, associating the comment with a neutrality category of the plurality of categories, the neutrality category associated with neutrality to the posted content item, and if the comment is determined not to satisfy the neutrality score threshold, passing the comment to a third classification determination. 7. The computer-implemented method of claim 6, wherein the third classification determination comprises: determining, based on the machine learning model, whether the comment satisfies an agreement score threshold, and if the comment is determined to satisfy the agreement score threshold, associating the comment with an agreement category of the plurality of categories, the agreement category associated with agreement with the posted content item, and if the comment is determined not to satisfy the agreement score threshold, associating the comment with a disagreement category of the plurality of categories, the disagreement category associated with disagreement with the posted content item. 8. The computer-implemented method of claim 7, wherein the first comment is selected for inclusion in the comment sample based on the first comment being associated with the agreement category, and the second comment is selected for inclusion in the comment sample based on the second comment being associated with the disagreement category. 9. The computer-implemented method of claim 1, further comprising ranking the plurality of comments based on ranking criteria, wherein the ranking criteria comprise comment engagement information, the selecting the first comment of the plurality of comments is further based on the ranking, and the selecting the second comment of the plurality of comments is further based on the ranking. 10. The computer-implemented method of claim 9, wherein the comment engagement information comprises at least one of a number of likes each comment receives or a number of replies each comment receives. 11. A system comprising: at least one processor; and a memory storing instructions that, when executed by the at least one processor, cause the system to perform a method comprising: receiving a plurality of comments to a posted content item; associating each of the plurality of comments with at least one category of a plurality of categories based on a machine learning model; selecting a first comment of the plurality of comments for inclusion in a comment sample to be presented in a graphical user interface based on the first comment being associated with a first category of the plurality of categories; and selecting a second comment of the plurality of comments for inclusion in the comment sample based on the second comment being associated with a second category of the plurality of categories. 12. The system of claim 11, wherein the associating each of the plurality of comments with at least one category of the plurality of categories based on the machine learning model comprises determining, based on the machine learning model, whether a comment satisfies a relevance score threshold indicative of relevance to the posted content item. 13. The system of claim 11, wherein the associating each of the plurality of comments with at least one category of the plurality of categories based on the machine learning model comprises determining, based on the machine learning model, whether a comment satisfies an agreement score threshold indicative of agreement with the posted content item. 14. The system of claim 11, wherein the associating each of the plurality of comments with at least one category of the plurality of categories based on the machine learning model comprises determining, based on the machine learning model, whether a comment satisfies a neutrality score threshold indicative of neutrality with regard to the posted content item. 15. The system of claim 11, wherein the associating each of the plurality of comments with at least one category of the plurality of categories based on the machine learning model comprises, for each comment: determining, based on the machine learning model, whether the comment satisfies a relevance score threshold, and if the comment is determined not to satisfy the relevance score threshold, associating the comment with a non-relevance category of the plurality of categories, the non-relevance category associated with non-relevance to the posted content item, and if the comment is determined to satisfy the relevance score threshold, passing the comment to a second classification determination. 16. A non-transitory computer-readable storage medium including instructions that, when executed by at least one processor of a computing system, cause the computing system to perform a method comprising: receiving a plurality of comments to a posted content item; associating each of the plurality of comments with at least one category of a plurality of categories based on a machine learning model; selecting a first comment of the plurality of comments for inclusion in a comment sample to be presented in a graphical user interface based on the first comment being associated with a first category of the plurality of categories; and selecting a second comment of the plurality of comments for inclusion in the comment sample based on the second comment being associated with a second category of the plurality of categories. 17. The non-transitory computer-readable storage medium of claim 16, wherein the associating each of the plurality of comments with at least one category of the plurality of categories based on the machine learning model comprises determining, based on the machine learning model, whether a comment satisfies a relevance score threshold indicative of relevance to the posted content item. 18.
