Sentence splitting

Concept recognition is an essential task in biomedical information extraction, presenting several complex and unsolved challenges. The development of such solutions is typically performed in an ad-hoc manner or using general information extraction frameworks, which are not optimized for the biomedical domain and normally require the integration of complex external libraries and/or the development of custom tools.

We experiment with splitting words into their stem and suffix components for modeling morphologically rich languages. We show that using a morphological analyzer and disambiguator results in a significant perplexity reduction in Turkish. We present flexible n-gram models, FlexGrams, which assume that the n−1 tokens that determine the probability of a given token can be chosen anywhere in the sentence rather than the preceding n − 1 positions. Our final model achieves 27% perplexity reduction compared to the standard n-gram model. ...

Sentiment analysis of citations in scientific papers and articles is a new and interesting problem due to the many linguistic differences between scientific texts and other genres. In this paper, we focus on the problem of automatic identification of positive and negative sentiment polarity in citations to scientific papers. Using a newly constructed annotated citation sentiment corpus, we explore the effectiveness of existing and novel features, including n-grams, specialised science-specific lexical features, dependency relations, sentence splitting and negation features. ...

231 Force: The complementisers that/if in a sentence such as I didn’t know [that/if he was lying] are said to indicate that the bracketed clauses are declarative/interrogative in force (in the sense that they have the force of a question/a statement). In work on split CP projections by Luigi Rizzi (discussed in §9.2-§9.3), complementisers are said to constitute a Force head which can project into a Force Phrase.

In GMAT sentences, look closely for split infinitives. An infinitive is the plural form of an action verb, preceded by the word “to.” If to is separated from its corresponding verb, then you’re dealing with a “split infinitive” and the sentence is grammatically incorrect. improper (split): The executive was compelled to, by greed and ambition, work more and more hours each day. correct: The executive was compelled by greed and ambition to work more and more hours each day. improper (split): Meteorologists have been known to inaccurately predict snowstorms.

Analysing English Sentences provides a concise and clear introduction to current work in syntactic theory, drawing on the key concepts of Chomsky’s Minimalist Program. Assuming little or no prior knowledge of syntax or Minimalism, Radford outlines the core concepts and leading ideas and how they can be used to describe various aspects of the syntax of English. A diverse range of topics is covered, including syntactic structure, null constituents, head movement, case and agreement, and split projections.
