This document describes rationales for some of the design decisions behind the Revised Report on the Algorithmic Language Scheme. The focus is on changes made since the last revision on the report. Moreover, numerous fundamental design decisions of Scheme are also explained. This report also contains some historical notes.

This article summarizes work on developing a learning theory account for the major learning and statistics based approaches used in natural language processing. It shows that these approaches can all be explained using a single distribution free inductive principle related to the pac model of learning. Furthermore, they all make predictions using the same simple knowledge representation a linea...

The 2008 Blizzard speech synthesis challenge provided participants with an opportunity to evaluate their systems in UK English and Mandarin. This paper describes the work behind three IBM systems submitted to the challenge for these two languages. The systems presented are concatenative unit-selection text-to-speech synthesis systems consisting of a core algorithmic base, as well as some algori...

Eden is a parallel functional programming language which extends Haskell with constructs for the definition and instantiation of parallel processes. Processes evaluate function applications remotely in parallel. The programmer has control over process granularity, data distribution, communication topology, and evaluation site, but need not manage synchronisation and data exchange between proces...

A language containing no words with repeated elements is simple. And a language which is not necessary simple is called non-simple in this paper. Björner and Ziegler [3] presented three plausible extensions of greedoids to non-simple languages. We shall show that when choosing one of their definitions they called ’polygreedoid’ and replacing generalized bottleneck functions of the objective fun...

OBJECTIVE Identify the lexical content of a large corpus of ordinary medical records to assess the feasibility of large-scale natural language processing. METHODS A corpus of 560 megabytes of medical record text from an academic medical center was broken into individual words and compared with the words in six medical vocabularies, a common word list, and a database of patient names. Unrecogn...

In this paper, we study the problem of predicting the algorithmic approach useful for solving a programming problem given its natural language description. As an auxiliary task, we also try to predict the difficulty of a problem given its natural language description. In order to solve this problem, we built our own dataset using 2 popular algorithmic programming websites, namely, Codechef www....

The complexity of current software tools increases with the problem solving tasks they are designed to assist and mainly dedicated computer educated people. On other hand technology is deeply involved in people’s everyday life. This gap deepens stresses education. purpose this paper discuss feasibility a new based methodology on that can be manipulated through use natural language. By computati...
