Arabic Trends: a daily-updated monitor corpus of news articles

The Arabic Trends corpus is an Arabic monitor corpus made up of news articles or other sources that are regularly updated from their RSS feeds (newsfeeds). The Arabic trends corpus is updated daily with new texts and grows by about 1–2 million words each day. These regular updates enable you to use the diachronic analysis tool and study word usage changes.

Part-of-speech tagset

The Arabic Trends corpus is tagged by the CAMeL tool using the POS CAMeL tagset.

How are Trends corpora updated?

New texts are downloaded every four hours. Every Wednesday, all texts downloaded the previous week till the end of Sunday are added to the corpus. Duplicate and near-duplicate texts within the same month are removed, but they are kept in different months, e.g. if the same text appears in June twice, only one instance is kept. If the same text appears once in June and once in July, both are kept.
