Prior Art Search is a task of querying and retrieving the patents in order to uncover any knowledge existing prior to the inventor’s question or invention at hand. For addressing this task, we present a contemporary approach that has been evaluated during Trecchem for its ability to adapt to text containing chemistry-based information. The core of the framework is an index of 1.3 million chemis...

The Wikipedia XML collection turned out to be rich of marked-up phrases as we carried out our INEX 2007 experiments. Assuming that a phrase occurs at the inline level of the markup, we were able to identify over 18 million phrase occurrences, most of which were either the anchor text of a hyperlink or a passage of text with added emphasis. As our IR system — EXTIRP — indexed the documents, the ...

A major engineering challenge in statistical machine translation systems is the efficient representation of extremely large translation rulesets. In phrase-based models, this problem can be addressed by storing the training data in memory and using a suffix array as an efficient index to quickly lookup and extract rules on the fly. Hierarchical phrasebased translation introduces the added wrink...

Businesses that rely on a value-added network to provide information processing and communications services are only as secure as the network itself. The customer should understand the types of processing and control services provided by such vendors, and the potential exposures that use of these networks can entail. This article describes the control issues that must be addressed, the controls...
