The Verbmobil treebanks of spoken German, English, and Japanese are part of the Verbmobil project, which has the overriding goal to develop a speaker-independent system for the translation of spontaneous speech. In the framework of this language technology project, the treebanks provide training data for a variety of language technology modules. The(More)
For languages whose character set is very large and whose orthography does not require spacing between words, such as Japanese, tokenizing and part-of-speech tagging are often the difficult parts of any morphological analysis. For practical systems to tackle this problem, uncontrolled heuristics are primarily used. The use of information on character sorts,(More)
A patient with mediastinal malignant fibrous histiocytoma (MFH) apparently developing from a foreign body granuloma is reported. A 72-year-old man was admitted to our hospital complaining of generalized fatigue and palpitations. He had undergone surgery for pulmonary tuberculosis 46 years previously. Radiography and computed tomography of the chest showed a(More)
This is a progress report on ongoing research aimed at proposing a ‘reference’ morphosyntactic part-of-speech tagset for the Japanese language. Such a tagset should be linguistically motivated, explicit, broadly applicable, and computationally tractable. Being well defined, such a tagset should be easily adapted in specific ways (e.g. limited, extended or(More)
A 41-year-old man was shot three times with a custom-made handgun. There were six small round wounds on the surface from two bullets that went into the body and one bullet found in a wall behind the victim at the scene. The gunshot wound in the left supraclavicular region bled massively. He was transferred to our hospital and soon fell into shock. A chest(More)
A rare case of synchronous double lung cancers having developed from bilateral bullous disease is reported. A 51-year-old man was admitted because of severe cough. Imaging studies revealed a left apical bulla measuring 10 cm, and another bulla measuring 8 cm containing viscous fluid on the right apex. In the next year, chest computed tomography showed(More)
A 73-year-old male presented with bloody sputa for a month. Chest computed tomography (CT) showed a large mass about 7 cm in diameter in the right lower lobe. Bronchoscopic curette cytology revealed class V and a suspected adenocarcinoma, although a systemic evaluation demonstrated no metastatic lesion. The patient underwent a right lower lobectomy and(More)
A 25-year-old man was referred to our hospital in June 2000 for treatment of massive enlargement of residual pulmonary metastases from a nonseminomatous germ cell testicular tumor. He had undergone right orchiectomy followed by cisplatin-based combination chemotherapy 7 years ago. Chest radiography and computed tomography showed complete opacification of(More)
