... use of all records of TC winds with Poisson process for modeling TC recurrence is necessary to better evaluate TC wind maxima. Except some special cases as shown in the main text, maximum winds ... convert to 3-gust speeds or 10 min-mean for use in structural design. It may take time to get better anemometers and measurement works, the available wind data obtained by VILD anemometers...

... word contexts. The original idea of LSA and LDA is to learn “top- ics” from documents, whereas in our scenario word contexts rather than documents are used, i.e., a small number of words before and after ... instrument for inves- tigating the diachronic development of word senses in a way that allows for a better under- standing of the nature of semantic change in general. For this purpose...

In our experiments, this method yields ... obtained in the extraction process as cor- rect frames. The experiments on the large corpus give better results than the ones on the small one, and grouping similar prepositions together is u...

We argue that building such predictive mod- els can help us better evaluate performance of NLP components that cannot be distin- guished based on F-score alone, ... all instances) is mathematically equivalent to micro- averaged recall; however, macro-averaging better reflects performance on small classes, and is com- monly used for unbalanced cla...

... but to a SQL database for a better query performance. The DDD data model can be seen as an exten- sion of NOM. Because the corpus contains mul- tiple versions of documents, coordination of an- notations ... along a single timeline is not sufficient. Therefore DDD segments refer to a specific version of a document. DDD defines how alignments are modeled, thus elevating them from the level of st...

In this paper, we focus on generic document summarization and keyword extraction for single documents. Document su...
