The DARPA RATS program was established to foster development of language technology systems that can perform well on speaker-to-speaker communications over radio channels that evince a wide range in the type and extent of signal variability and acoustic degradation. Creating suitable corpora to address this need poses an equally wide range of challenges for the collection, annotation and qualit...

To advance information extraction and question answering technologies toward a more realistic path, the U.S. NIST (National Institute of Standards and Technology) initiated the KBP (Knowledge Base Population) task as one of the TAC (Text Analysis Conference) evaluation tracks. It aims to encourage research in automatic information extraction of named entities from unstructured texts with the ul...

We present a system for the linguistic exploration and analysis of lexical cohesion in English texts. Using an electronic thesaurus-like resource, Princeton WordNet, and the Brown Corpus of English, we have implemented a process of annotating text with lexical chains and a graphical user interface for inspection of the annotated text. We describe the system and report on some sample linguistic ...

Comma placements in Chinese text are relatively arbitrary although there are some syntactic guidelines for them. In this research, we attempt to improve the readability of text by optimizing comma placements through integration of linguistic features of text and gaze features of readers. We design a comma predictor for general Chinese text based on conditional random field models with linguisti...

Macrophone is a corpus of approximately 200,000 utterances, recorded over the telephone from a broad sample of about 5,000 American speakers. Sponsored by the Linguistic Data Consortium (LDC), it is the first of a series of similar data sets that will be colected for major languages of the world in a cooperative project called Polyphone. It is designed to provide telephone speech suitable for t...

The Call My Net 2015 (CMN15) corpus presents a new resource for Speaker Recognition Evaluation and related technologies. The corpus includes conversational telephone speech recordings for a total of 220 speakers spanning 4 languages: Tagalog, Cantonese, Mandarin and Cebuano. The corpus includes 10 calls per speaker made under a variety of noise conditions. Calls were manually audited for langua...

Corpora of sentences annotated with grammatical information have been deployed by extending the basic lexical and morphological data with increasingly complex information, such as phrase constituency, syntactic functions, semantic roles, etc. As these corpora grow in size and the linguistic information to be encoded reaches higher levels of sophistication, the utilization of annotation tools an...

This paper introduces the Prague Czech-English Dependency Treebank (PCEDT), a new Czech-English parallel resource suitable for experiments in structural machine translation. We describe the process of building the core parts of the resources – a bilingual syntactically annotated corpus and translation dictionaries. A part of the Penn Treebank has been translated into Czech, the dependency annot...

The Open Linguistics Working Group (OWLG) brings together researchers from various fields of linguistics, natural language processing, and information technology to present and discuss principles, case studies, and best practices for representing, publishing and linking linguistic data collections. A major outcome of our work is the Linguistic Linked Open Data (LLOD) cloud, an LOD (sub-)cloud o...
