We have argued elsewhere (Church and Mercer, 1993) that text is more available than ever before, and that the availability of massive quantities of data has been responsible for much of the recent interest in text analysis. Ideally, we would hope that this data would be distributed in a convenient format such as SGML (Goldfarb, 1990), but in practice, we usually have to work with the data in wh...

To allow connectivity between the General Switched Telephone Network facsimile service (GSTN fax) and the e-mail-based Internet Fax service (i-fax) an "Internet Fax Gateway" is required. This document provides recommendations for the functionality of Internet Fax Gateways. In this context, an "offramp gateway" provides facsimile data transmission from i-fax to GSTN fax; vice versa, an "onramp g...

Conventional halftoning methods such as error diffusion and ordered dithering are poorly suited to the compression of halftone images using the baseline fax compression schemes CCITT G3 and G4. This paper proposes an efficient and flexible solution for binary representation of mixed content documents using CCITT G3/G4 compression. The solution includes two variations which we refer to as FastFa...

There has been a growing interest in recent years in developing real-time voice and fax communication software for use over the Internet. This paper discusses the design of an Internet Telephony Gateway (ITG) that is used to support the delivery of fax and/or voice services through the Internet to conventional telephones and fax machines on the Public Switched Telephone Network (PSTN). The inte...
