  • We present new statistical models for jointly labeling multiple sequences and apply them to the combined task of partof-speech tagging and noun phrase chunking. The model is based on the Factorial Hidden Markov Model (FHMM) with distributed hidden states representing partof-speech and noun phrase sequences. We demonstrate that this joint labeling approach, by enabling information sharing between tagging/chunking subtasks, outperforms the traditional method of tagging and chunking in succession.

  • In [2], the problem of discovering sequential patterns over large databases of customer transactions is considered. The proposed algorithms generate a data sequence for each customer from the database and search on this set of se- quences for a frequent sequential pattern. For example, the algorithms can discover that customers typically rent “Star Wars,” then “Empire Strikes Back,” and then “Return of the Jedi.

  • This paper discusses a sequence of deductive parsers, called PAD1 - PAD5, that utilize an a x i o m a t i z a t i o n of the p r i n c i p l e s a n d parameters of GB theory, including a restricted transformational component (Move-a). PAD2 uses an inference control strategy based on the "freeze" predicate of Prolog-II, while PAD3 - 5 utilize the Unfold-Fold transformation to transform the original axiomatization into a form that functions as a recursive descent Prolog parser for the fragment. INTRODUCTION In this paper I...

  • This book provides a practical approach for MR imaging of the focal and diffuse liver lesions based on the state-of-the-art MR imaging sequences, computer-generated drawings, concise figure captions, relevant and systematic (differential) diagnostic information, recent literature references, and patient management possibilities. MR imaging findings are correlated to ultrasound, computed tomography, and pathology when appropriate.

  • It would have been much easier for me to write this ACKNOWLEDGEMENT if I were a well established scientist of international fame. I could then write in a pastoral manner about sweet recollections of the past, starting with a certain scientist, also internationally famous of course, who came to visit my lab and suggested that I should write such a book. Knowing that the whole world was watching and waiting, I had set aside all the other very important works and devoted most of my time to the writing of this path-blazing masterpiece.

  • In a world of 6 billion inhabitants, international migration seems insignificant as it comes to represent about three per cent of the world. Most migration, in fact is internal—rural to rural, rural to urban—and international migration in many cases follows a sequence of stages, from rural to urban, then to the international sphere. However, international migration takes on greater relevance because of the significant volume of remittances worldwide. To many, remittances have become a stable source of finances (Ratha, 2003, Sørensen, 2002).

  • The Internet is a loosely coupled federation of computer servers and clients. Clients are sometime disconnected, and yet they need to be able continue functioning. Rather than building tightly- coupled RPC-based applications, Internet-scale applications must be constructed as asynchronous tasks structured as workflows involving multiple autonomous agents. eMail gives an intuitive understanding of these design issues. You want to be able to read and send mail...

  • This can best be described with an example. Building a house consists of a number of separate, but inter-related activities: digging and laying the foundations; building the walls; installing the doors and windows; plastering the walls; constructing the roof; installing the plumbing. The sequence dictates that digging the foundations comes before building the walls; while dependencies include the fact that you cannot start installing doors and windows until the walls have reached a certain height; or you cannot finish plastering until the plumbing has been fully installed.
