LDC data and commercial technology development For-profit organizations are reminded that an LDC membership is a pre-requisite for obtaining a commercial license to almost all LDC databases. Non-member organizations, including non-member for-profit organizations, cannot use LDC data to develop or test products for commercialization, nor can they use LDC data in any commercial product or for any commercial purpose. LDC data users should consult corpus-specific license agreements for limitations on the use of certain corpora.

New publications:

(1) BOLT Egyptian Arabic-English Word Alignment -- Conversational Telephone Speech Training<https://catalog.ldc.upenn.edu/LDC2020T05> was developed by LDC and consists of 153,171 words of Egyptian Arabic and English parallel text enhanced with linguistic tags to indicate word relations.

The source data in this release consists of transcripts of Egyptian Arabic conversational telephone speech (CTS) from LDC's CALLHOME and CALLFRIEND collections (LDC97S45<https://catalog.ldc.upenn.edu/LDC97S45>, LDC97T19<https://catalog.ldc.upenn.edu/LDC97T19>, LDC2002S37<https://catalog.ldc.upenn.edu/LDC2002S37>, LDC2002T38<https://catalog.ldc.upenn.edu/LDC2002T38>, LDC96S49<https://catalog.ldc.upenn.edu/LDC96S49>) that was translated into English by professional translation agencies and annotated for the word alignment task.

The BOLT word alignment task was built on treebank annotation. Egyptian Arabic source tree tokens were automatically extracted from tree files in LDC's BOLT Egyptian Arabic Treebank, which had been tagged for part-of-speech and syntactically annotated. That data was then aligned and annotated for the word alignment task.

BOLT Egyptian Arabic-English Word Alignment -- Conversational Telephone Speech Training is distributed via web download.

2020 Subscription Members will automatically receive copies of this corpus. 2020 Standard Members may request a copy as part of their 16 free membership corpora. Non-members may license this data for a fee. * (2) EVALution<https://catalog.ldc.upenn.edu/LDC2020T06> was developed by The Hong Kong Polytechnic University<https://www.polyu.edu.hk/web/en/home/index.html>. It is comprised of English and Mandarin Chinese data sets -- EVALution 1.0 and EVALution-Man, respectively -- that contain semantic relations and metadata for training and evaluating distributional semantic models.

EVALution 1.0 consists of approximately 7500 English tuples extracted from ConceptNet 5.0<http://conceptnet.io/> and WordNet 4.0<https://wordnet.princeton.edu/> and filtered through automatic methods and crowd-sourcing. Several semantic relations between word pairs were instantiated, including hypernymy, synonymy, antonymy and meronymy. The corpus also includes additional information that can be used to filter the pairs or to analyze the results, such as relation domain, word frequency, word part-of-speech and word semantic field.

EVALution-MAN consists of Chinese word pairs from two sources: Chinese Wordnet<http://cwn.ling.sinica.edu.tw/> and humans who completed an elicitation task by supplying missing words to sentences. The human-supplied sentence word pairs were then judged by human raters for reliability.

EVALution is distributed via web download.

2020 Subscription Members will receive copies of this corpus provided they have submitted a completed copy of the special license agreement. 2020 Standard Members may request a copy as part of their 16 free membership corpora. Non-members may license this data for a fee. * (3) Mixer 4 and 5 Speech<https://catalog.ldc.upenn.edu/LDC2020S03> was developed by LDC and contains approximately 14,185 hours of audio recordings of conversational telephone speech, interviews, elicitation exercises and transcript readings involving 616 distinct speakers. The material was collected in 2007 as part of the Mixer project - which supported speaker recognition for a variety of research tasks - and recordings in this corpus were used in the 2008 NIST Speaker Recognition Evaluation.

The data in this release was collected by LDC at its Human Subjects Data Collection Laboratories<https://www.ldc.upenn.edu/about/facilities/human-subjects-collection> in Philadelphia and by the International Computer Science Institute <http://www.icsi.berkeley.edu/icsi/> (ICSI) at the University of California, Berkeley, as a collaborative, carefully coordinated activity at both recording sites. The Mixer 4 and 5 collection contains 2,568 recordings made via the public telephone network and 2,152 sessions of multiple microphone recordings in office-room settings.

The telephone protocol connected recruited speakers through a robot operator to carry on casual conversations. In Mixer 4, 400 subjects made ten 10-minute calls; half of those subjects also visited one of the collection sites where they made two telephone calls while also being recorded on a cross-channel platform. In Mixer 5, 300 subjects each completed ten calls and six interview sessions at either LDC or ICSI; those sessions were conducted on a cross channel platform and included a telephone call in one of three vocal-effort conditions - normal, high and low. Mixer participants were nearly all native English speakers, the rest being bilingual English speakers.

This release includes metadata about the calls and speakers, along with time-aligned entries for many of the component portions of the recording sessions.

Mixer 4 and 5 Speech is distributed via hard drive.

2020 Subscription Members will automatically receive copies of this corpus. 2020 Standard Members may request a copy as part of their 16 free membership corpora. This corpus is a members-only release and is not available for non-member licensing. Contact ldc at ldc.upenn.edu for information about membership. *
