AspectBench 1.0 (HBS Subset) is an HBS language dataset (hbs, ISO 639-3) containing online news articles, mainly in Serbian and Croatian, for studying sentiment towards target entities like companies and brand names. It is a document-level aspect-based sentiment analysis dataset containing long articles and unseen or new target entities that are not encountered during training. The article text has been filtered to remove URLs.
The dataset contains 82,714 distinct records covering 65 targets. The articles were published between 31 December 2012 and 30 December 2023. The held-out test set contains 12,407 records. The other 70,307 records form one training and validation pool. Three random splits of this pool are provided. Each split contains 57,901 training records and 12,406 validation records. Only the source-system internal identifier was removed. The article text, sentiment labels, aspect names, and aspect tags are unchanged.
Each record is one document-aspect pair. It contains the full article headline and body, one target company or brand, the target's tracked keyword patterns, the number of matched mentions, publication metadata, and one sentiment label: negative (-1), neutral (0), or positive (1). A single article can occur in more than one record when it has more than one target. The literal <aspect>...</aspect> tags in the article mark the mentions that refer to that record's target. These tags are part of the annotation.

{
"uuid": "11854",
"article": "bankama u srbiji bolje nego ikada ... <aspect>telenor banka</aspect> ponovila je los rezultat iz prve godine poslovanja, a strucnjaci kazu da je to ocekivano zbog ogromnih ulaganja i da bi odrzivost ovog modela poslovanja mogla da se oceni posle cetiri, pet godina. ...",
"translation": "Banks in Serbia are doing better than ever ... Telenor Bank repeated the weak result from its first year of operation, while experts said this was expected because of substantial investments and that the sustainability of this business model could be assessed after four or five years. ...",
"aspect": "Telenor banka",
"keywords": ["telenor bank*", "теленор банк*"],
"sentiment": -1,
"language": "Serbo-Croatian",
"published": "2017-05-02T22:00:00.000Z",
"country": "RS"
}
Although both records originate from the same article text, their target aspects and corresponding sentiment labels differ. The first record is positive because the article reports that Erste banka achieved its best result since entering the Serbian market. The second record is negative because Telenor banka is discussed as repeating a weak business result. This illustrates why the task is formulated as document-level entity-targeted sentiment analysis: sentiment is predicted with respect to a specific target entity rather than assigned broadly to the document as a whole.
The same training and validation pool is supplied under three splits. Therefore, the four partition files contain 223,328 record entries in total. This is not the number of distinct records. The target catalogue contains 65 targets and no dataset records.
