(1) Arabic Speech Recognition Pronunciation Dictionary was developed by the Qatar Computing Research Institute. It contains approximately two million pronunciation entries for 526,000 Modern Standard Arabic words, for an average of 3.84 pronunciations for each grapheme word. The dictionary was developed from news archive resources, including the Arabic news website Aljazeera.net. The selected words were those that occurred more than once in the news collection. 
Arabic Speech Recognition Pronunciation Dictionary is distributed via web download.

(2) IARPA Babel Vietnamese Language Pack IARPA-babel107b-v0.7 was developed by Appen for the IARPA (Intelligence Advanced Research Projects Activity) Babel program. It contains approximately 201 hours of Vietnamese conversational and scripted telephone speech collected in 2012 along with corresponding transcripts.

The Babel program focuses on underserved languages and seeks to develop speech recognition technology that can be rapidly applied to any human language to support keyword search performance over large amounts of recorded speech.

The Vietnamese speech in this release represents that spoken in the North, North-Central, Central and Southern dialect regions in Vietnam. The gender distribution among speakers is approximately equal; speakers' ages range from 16 years to 64 years. Calls were made using different telephones (e.g., mobile, landline) from a variety of environments including the street, a home or office, a public place, and inside a vehicle.

Transcripts are encoded in UTF-8.

(3) MWE-Aware English Dependency Corpus was developed by the Nara Institute of Science and Technology Computational Linguistics Laboratory and consists of English compound function words annotated in dependency format. The data is derived from the Wall Street Journal portion of OntoNotes Release 5.0 (LDC2013T19).
Compound function words are a type of multiword expression (MWE). MWEs are groups of tokens that can be treated as a single semantic or syntactic unit. Doing so facilitates natural language processing tasks such as constituency and dependency parsing.

These are Eastern Manding languages in the Mande Group of the Niger-Congo language family. LDC released a Mawukakan Lexicon (LDC2005L01) in 2005 and a Maninkakan Lexicon (LDC2013L01) in 2013.

This lexicon is presented using a Latin-based transcription system because the Latin alphabet is familiar to the majority of Mandekan language speakers and it is expected to facilitate the work of researchers interested in this resource.

Chilin HK and LDC partner on distribution of parallel patent data

Chilin HK Limited (Chilin) and LDC are pleased to announce that the parallel data source developed by Chilin, A Corpus of Chinese-English Parallel Sentences Extracted from Patents, 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.

The Chilin Corpus has primarily resulted from training corpus and test sets developed specifically for the Tokyo-based NTCIR 2009 & 2010 competitions on Patent MT (machine translation), which drew more than 30 international teams:


The training corpus is drawn from a much larger curated corpus of parallel Chinese-English sentences and sentence fragments which have been winnowed from an even larger corpus of more than 300k parallel Chinese-English patents in different fields, initially at the Research Centre on Language Information Sciences, City University of Hong Kong (authors:  Benjamin Tsou, Bin Lu, and Kapo Chow). This data set is available from LDC under the following reference:


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$5000, discounted to US$4000 for LDC for-profit members, under a commercial license.

New Corpora

(1) IARPA Babel Turkish Language Pack IARPA-babel105b-v0.5 was developed by Appen for the IARPA (Intelligence Advanced Research Projects Activity) Babel program. It contains approximately 213 hours of Turkish conversational and scripted telephone speech collected in 2012 along with corresponding transcripts.

The Babel program focuses on underserved languages and seeks to develop speech recognition technology that can be rapidly applied to any human language to support keyword search performance over large amounts of recorded speech.

The Turkish speech in this release represents that spoken in seven dialect regions in Turkey. The gender distribution among speakers is approximately equal; speakers' ages range from 16 years to 70 years. Calls were made using different telephones (e.g., mobile, landline) from a variety of environments including the street, a home or office, a public place, and inside a vehicle.

Transcripts are encoded in UTF-8.

IARPA Babel Turkish Language Pack IARPA is distributed via web download.

2016 Subscription Members will receive two copies of this corpus provided they have submitted a completed copy of the special license agreement. 2016 Standard Members may request a copy as part of their 16 free membership corpora. Non-members may license this data for a fee.

(2) KAFD: Arabic Font Database was developed by King Fahd University of Petroleum & Minerals and Qassim University. It is comprised of approximately 2.5 million scanned Arabic printed pages in a variety of fonts, sizes and resolutions along with corresponding transcripts. KAFD was designed for research in Arabic text recognition.

The scanned Arabic texts were collected from publications covering various subjects such as religion, medicine, science and history. Texts were printed in 40 different fonts, 10 sizes and four styles. Scans were made at 100, 200, 300 and 600 dpi (dots per inch).

The database is available in two formats: at the page level and at the line level. Images are presented as TIFF images and transcripts are in plain text format. Individual font folders are compressed into RAR archives.

The data is divided into training, validation and test sets.

2016 Subscription Members will automatically receive two copies of this corpus.  2016 Standard Members may request a copy as part of their 16 free membership corpora.  Non-members may license this data for a fee.

(3) Richer Event Description was developed by the University of Colorado Boulder-CLEAR (Computational Language and Education Research), Carnegie Mellon University and LDC. It consists of coreference, bridging and event-event relations (temporal, causal, subevent and reporting relations) annotations over 95 English newswire, discussion forum and narrative text documents, covering all events, times and non-eventive entities within each document.
RED annotation is intended to join different annotation layers and to provide a rich representation of event phenomena.

Documents were annotated twice -- in a markable pass and in an event annotation phase. Annotation and source documents are divided into three partitions: (1) 20 newswire summarization documents, (2) 20 discussion forum documents and newswire annotations used in the original RED pilot annotations, and (3) 55 documents annotated by a range of DEFT (Deep Exploration and Filtering of Test) annotation formats. Data is presented as UTF-8 encoded xml and plain text.

2016 Subscription Members will automatically receive two copies of this corpus.  2016 Standard Members may request a copy as part of their 16 free membership corpora.  Non-members may license this data for a fee.
