We describe a pattern-based system for polarity classification from texts. Our system is currently restricted to the positive, negative or neutral polarity of phrases and sentences. It analyses the input texts with the aid of a polarity lexicon that specifies the prior polarity of words. A chunker is used to determine phrases that are the basis for a compositional treatment of phrase-level pola...

Document summarization involves reducing a text document into a short set of phrases or sentences that convey the main meaning of the text. In digital libraries, summaries can be used as concise descriptions which the user can read for a rapid comprehension of the retrieved documents. Most of the existing approaches rely on the classification algorithms which tend to generate “crisp” summaries,...

We investigate the automatic detection of sentences containing linguistic hedges using corpus statistics and syntactic patterns. We take Wikipedia as an already annotated corpus using its tagged weasel words which mark sentences and phrases as non-factual. We evaluate the quality of Wikipedia as training data for hedge detection, as well as shallow linguistic features.

The BLEU scores and translation fluency for the current state-of-the-art SMT systems based on IBM models are still too low for publication purposes. The major issue is that stochastically generated sentences hypotheses, produced through a stack decoding process, may not strictly follow the natural target language grammar, since the decoding process is directed by a highly simplified translation...

In experiments on a natural language information retrieval system that retrieves images based on textual captions, we show that syntactic complexity actually aids retrieval. We compare two types of captioned images, those characterized with full sentences in English, and those characterized by lists of words and phrases. The full-sentence captions show a 15% increase in retrieval accuracy over ...

The purpose of this study is to investigate problems and barriers of greenhouse growers in Isfahan Province, Iran using the qualitative paradigm. Data were collected with semi-structured interviews and direct observations. Most participants were questioned by phone interview. The response rate to phone calls was 59.2 percent. Data are analyzed by the grounded theory. Structural analysis is util...

How does language influence the emotions and actions of large audiences? Functionally, emotions help address environmental uncertainty by constraining the body to support adaptive responses and social coordination. We propose emotions provide a similar function in language processing by constraining the mental simulation of language content to facilitate comprehension, and to foster alignment o...

(National Laboratory of Pattern Recognition, Institute of Automation, Chinese Academy of Sciences, Beijing 100080, China) Abstract: Based on the analysis of the usage and the syntactic function of Chinese punctuations, this paper proposes a new hierarchical approach to parsing the long Chinese sentences. In traditional parsing approaches, the parsing procedure is performed on one-level and the ...
