Focusing for Pronoun Resolution in English Discourse: An Implementation

Anaphora resolution is one of the most active research areas in natural language processing. This study examines focusing as a tool for the resolution of pronouns which are a kind of anaphora. Focusing is a discourse phenomenon like anaphora. Candy Sidner formalized focusing in her 1979 MIT PhD thesis and devised several algorithms to resolve definite anaphora including pronouns. She presented her theory in a computational framework but did not generally implement the algorithms. Her algorithms related to focusing and pronoun resolution are implemented in this thesis. This implementation provides a better comprehension of the theory both from a conceptual and a computational point of view. The resulting program is tested on different discourse segments, and evaluation and analysis of the experiments are presented together with the statistical results.Comment: iii + 49 pages, compressed, uuencoded Postscript file; revised version of the first author's Bilkent M.S. thesis, written under the supervision of the second author; notify Akman via e-mail ([email protected]) or fax (+90-312-266-4126) if you are unable to obtain hardcopy, he'll work out somethin

Evaluation of patients with fibrotic interstitial lung disease: Preliminary results from the Turk-UIP study

OBJECTIVE: Differential diagnosis of idiopathic pulmonary fibrosis (IPF) is important among fibrotic interstitial lung diseases (ILD). This study aimed to evaluate the rate of IPF in patients with fibrotic ILD and to determine the clinical-laboratory features of patients with and without IPF that would provide the differential diagnosis of IPF. MATERIAL AND METHODS: The study included the patients with the usual interstitial pneumonia (UIP) pattern or possible UIP pattern on thorax high-resolution computed tomography, and/or UIP pattern, probable UIP or possible UIP pattern at lung biopsy according to the 2011 ATS/ERSARS/ALAT guidelines. Demographics and clinical and radiological data of the patients were recorded. All data recorded by researchers was evaluated by radiology and the clinical decision board. RESULTS: A total of 336 patients (253 men, 83 women, age 65.8 +/- 9.0 years) were evaluated. Of the patients with sufficient data for diag-nosis (n=300), the diagnosis was IPF in 121 (40.3%), unclassified idiopathic interstitial pneumonia in 50 (16.7%), combined pulmonary fibrosis and emphysema (CPFE) in 40 (13.3%), and lung involvement of connective tissue disease (CTD) in 16 (5.3%). When 29 patients with definite IPF features were added to the patients with CPFE, the total number of IPF patients reached 150 (50%). Rate of male sex (p<0.001), smoking history (p<0.001), and the presence of clubbing (p=0.001) were significantly high in patients with IPE None of the women <50 years and none of the men <50 years of age without a smoking history were diagnosed with IPE Presence of at least 1 of the symptoms suggestive of CTD, erythrocyte sedimentation rate (ESR), and antinuclear antibody (FANA) positivity rates were significantly higher in the non-IPF group (p<0.001, p=0.029, p=0.009, respectively). CONCLUSION: The rate of IPF among patients with fibrotic ILD was 50%. In the differential diagnosis of IPF, sex, smoking habits, and the presence of clubbing are important. The presence of symptoms related to CTD, ESR elevation, and EANA positivity reduce the likelihood of IPF

Zoobenthic fauna and seasonal changes of mamasin dam lake (Central part of Turkey)

WOS: 000270306500060This study was conducted at Mamasin dam lake of Aksaray between April 2002 and March 2003. Seasonal changes in the zoobenthic fauna as well as some physical and chemical parameters of lake were examined based on water samples collected from 4 stations selected in the lake. It was determined that zoobenthic organisms are composed of 86.23% chironomidae, 7.3% oligochaeta and 6.47% mollusca. Four species of chironomidae, 8 of oligochaeta and 5 of mollusca were detected. In respect to faunastic biomass, it was observed that zoobenthic organisms in the lake were maximum in autumn and minimum in spring. Some water quality parameters of 4 stations selected in the lake were measured. The evaluation of the data obtained from the stations and the previous studies revealed that the water quality of Mamasin dam lake is decaying as the pollution builds up and drawing near to the eutrophic level as the indicator species surfaced point out

Anti-hyperglycaemic, anti-oxidant and anti-hyperlipidaemic effects of <i style="mso-bidi-font-style:normal">Momordica charantia </i><span style="mso-bidi-font-style:italic">L. on streptozotocin-induced diabetic rats </span>

382-386The study was aimed to determine the effects of Momordica charantia (MC) on fasting blood glucose levels, oxidative stress and plasma lipid profile in streptozotocin (STZ)-induced diabetic rats. Diabetic rats were orally administered MC extract (200 mg/kg) and subcutaneous insulin (1 IU) for 21 days. MC and insulin treated groups showed a significant decrease in the fasting blood glucose levels from the 7th day (p < 0.001). There were no differences in HDL cholesterol and triglyceride levels. There was a decrease in the LDL and VLDL cholesterol levels (p < 0.05). Furthermore, treatment with MC and insulin reduced in the erythrocyte TOS levels (p < 0.05). However, there were no significant differences in plasma and erythrocyte TAS levels between the untreated diabetic group and MC group. The anti-hyperlipidaemic property of the MC extract was determined, while the more antioxidant and anti-hyperglycaemic features of the insulin was observed. Based on this information, it is considered that it will be more effective to use MC and exogenous insulin in combination for preventing complications such as oxidative stress and, hyperlipidaemia shaped by diabetes
