This edition of CL!NSS focuses on journalistic text re-use as previous year. News agencies are a prolific source of text on the Web and a valuable source of text in multiple languages. News stories generated by different authors, whether independently or derived from another story, typically exist as separate entities and consequently there is a need to link them.

Linking news stories covering the same events written in different languages offers a number of benefits. For example, in a multilingual environment, such as India, where the same news story is covered in multiple languages, a reader might want to refer to the local language version of a news story. News stories covering the same event(s), published in different languages, may also be rich sources of both parallel and comparable text, for example, parallel fragments in the news story, e.g. direct quotes or translation equivalents; comparable fragments, e.g. paraphrases. Therefore identification of similar news stories written in multiple languages offers a valuable multilingual resource. In the case of Indian languages there exist limited language resources for NLP and IR tasks. For instance, identifying comparable and parallel documents on the web would offer a potential (and abundant) source for deriving bilingual dictionaries and training statistical MT systems (Munteanu & Marcu, 2005; Barker & Gaizauskas, 2012).

In this edition, the aim is to identify the same story written across languages (English and Hindi) - a problem of cross-language news story detection. The task will involve identifying and linking news stories covering the same event in Hindi for the given English language news story.

We invite researchers and practitioners from all fields to participate.
