Portuguese Trends: a daily-updated monitor corpus of news articles
The Portuguese Trends corpus is a Portuguese monitor corpus made up of news articles or other sources that are regularly updated from their RSS feeds (newsfeeds). The Portuguese 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 including the timeline show_chart function and study word usage changes.
Part-of-speech tagset
The Portuguese Trends corpus was annotated by the FreeLing tool using the following part-of-speech tagset schema.
How is the Portuguese Trends corpus updated?
New texts are downloaded every four hours. Every Tuesday and Friday, all texts downloaded until the previous day 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.
