We present a new resource, the UnixMan Corpus, for studying language learning it the domain of Unix utility manuals. The corpus is built by mining Unix (and other Unix related) man pages for parallel example entries, consisting of English textual descriptions with corresponding command examples. The commands provide a grounded and ambiguous semantics for the textual descriptions, making the cor...

This paper describes a classifier that assigns semantic thesaurus categories to unknown Chinese words (words not already in the CiLin thesaurus and the Chinese Electronic Dictionary, but in the Sinica Corpus). The focus of the paper differs in two ways from previous research in this particular area. Prior research in Chinese unknown words mostly focused on proper nouns (Lee 1993, Lee, Lee and C...

Annotation studies in CL are generally unscientific: they are mostly not reproducible, make use of too few (and often non-independent) annotators and use guidelines that are often something of a moving target. Additionally, the notion of ‘expert annotators’ invariably means only that the annotators have linguistic training. While this can be acceptable in some special contexts, it is often far ...

The Coruña Corpus of scientific writing will be used for the diachronic study of scientific discourse from most linguistic levels and thereby contribute to the study of the historical development of English. The Coruña Corpus Tool is an information retrieval system that allows the extraction of knowledge from the corpus.

We provide a systematic study of previously proposed features for implicit discourse relation identification, identifying new feature combinations that optimize F1-score. The resulting classifiers achieve the best F1-scores to date for the four top-level discourse relation classes of the Penn Discourse Tree Bank: COMPARISON, CONTINGENCY, EXPANSION, and TEMPORAL. We further identify factors for ...

The few known palatographic studies on Estonian consonants date back to the 1970s, and no research in articulatory phonetics has been practised throughout the following four decades. Recently, the Estonian EPG corpus was recorded using a contemporary EPG system. In the paper we introduce first results on contemporary palatography patterns of Estonian sonorants and compare these to results from ...

Coverage of Infertility Treatment and Fertility Outcomes: Do Women Catch Up? The ageing of first-time mothers and the changes in women’s labor market conditions have been accompanied by the introduction and subsequent increase in the use of assisted reproductive therapies (ART) that help extend women’s reproductive lives. Considering the financial cost of infertility treatments, policy interven...

Deciding whether a word serves a discourse function in context is a prerequisite for discourse processing, and the performance of this subtask bounds performance on subsequent tasks. Pitler and Nenkova (2009) report 96.29% accuracy (F1 94.19%) relying on features extracted from gold-standard parse trees. This figure is an average over several connectives, some of which are extremely hard to cla...

This article is a survey of methods for measuring agreement among corpus annotators. It exposes the mathematics and underlying assumptions of agreement coefficients, covering Krippendorff’s alpha as well as Scott’s pi and Cohen’s kappa; discusses the use of coefficients in several annotation tasks; and argues that weighted, alpha-like coefficients, traditionally less used than kappa-like measur...

Assisted reproduction techniques (ART), in particular in-vitro fertilization and intra-cytoplasmic sperm injection, are the most advanced forms of infertility treatment. They involve numerous counseling, medical, surgical and laboratory-based steps. At each step various problems and complications could be encountered that challenge even the most experienced ART practitioners. Moreover, patients...
