New publications:

(1)  AttImam was developed by Al-Imam Mohammad Ibn Saud Islamic University and consists of approximately 2,000 attribution relations applied to Arabic newswire text from Arabic Treebank: Part 1 v 4.1 (LDC2010T13). Attribution refers to the process of reporting or assigning an utterance to the correct speaker.  

The source Arabic newswire was collected by LDC from Agence France Presse articles published in 2000. Files were annotated by native Arabic speakers and contain the following elements:

• Cue: the lexical anchor that connects the source with the content.
• Source: the entity or the agent that owns the content.
• Content: the basic element expressing the claim or the reported news.
• General Features: these can include such features as attribution style (direct or indirect), determinacy (factual or non-factual), and purpose (e.g., assertion, expression).

AttImam is distributed via web download.
