This paper presents a case study of discovering and classifying verbs in large web-corpora. Many tasks in natural language processing require corpora containing billions of words, and with such volumes of data co-occurrence extraction becomes one of the performance bottlenecks in the Vector Space Models of computational linguistics. We propose a co-occurrence extraction kernel based on ternary trees...
The Web has been flooded with highly heterogeneous data sources that freely offer their data to the public. Careful design and compliance to standards is a way to cope with the heterogeneity. However, any agreement and compliance is practically hard to achieve across different communities. In this work we describe a framework that enables the exploitation of content across different scientific disciplines...
The term Deep Web (sometimes also called Hidden Web) refers to the data content that is created dynamically as the result of a specific search on the Web. In this respect, such content resides outside web pages, and is only accessible through interaction with the web site typically via HTML forms. It is believed that the size of the Deep Web is several orders of magnitude larger than that of the so-called...
XML has become the de facto standard for representing and interchanging data in web-based applications. And XML view, a virtual window for specified users, has been widely applied. In practical system, users encounter the so-called view update problem when they need update source data through the view. For a long time, the view update problem is an open question in database community. With the development...
The available amount of geographic datasets has considerably grown. This is due to the increasing number of different devices used in collecting such data. Moreover, the amazing progress of the web that allows sharing and accessing to any type of information has further increased this availability. However, query evaluation in spatial data is often expensive, because these data have complex structures...
