JANA: A Human-Human Dialogues Corpus for Egyptian Dialect is now available through the LDC Catalog. This is a special release in addition to the LDC scheduled corpora for membership year 2016, available under separate terms.

JANA was developed by researchers at Cairo University and consists of 82 transcribed dialogues from call center inquiries annotated for dialogue acts. Data was collected from call centers for banks, airlines and mobile network providers in the form of spontaneous spoken telephone dialogues (52) and instant messaging dialogues (30) amounting to over 20,000 words.

Not-for-profit organizations may license this data set for US$25.00 under the LDC Not-for-Profit Membership Agreement or under the LDC User Agreement for Non-Members for use in linguistic research, education and non-commercial technology development. For-profit organizations may license this data for US$1650 under a commercial license.

Web pages about data management plans (DMPs) describe the Consortium’s capabilities to develop and implement project specific proposals. To satisfy requirements from funders like the National Science Foundation (NSF) that researchers deposit data in an accessible, trustworthy repository, LDC provides archiving services and makes data publicly available at a reasonable cost while protecting intellectual property rights and privacy concerns.

Browse the pages to learn more about the advantages of data center distribution, the details of NSF DMP requirements and the infrastructures and processes LDC has in place for storing and distributing resources over the long-term.
