    Patent Information on the Internet

    Many people believe that the entire world's information is somehow accessible on the Internet and costs virtually nothing to retrieve. Others view the Internet as a slow, overrated mechanism for obtaining information that may or may not be reliable. For the information specialist, the Internet has become another useful resource for obtaining information. This article is an attempt to provide an overview of free and commercial sites containing patent databases and to outline the possibilities as well as the limitations of these patent information sources. In addition to this written article, we have set up a Web site (http://chemsear.ch/chimia/) which contains all the important links as well as additional information about patents on the Internet

    The computer storage, retrieval and searching of generic structures in chemical patents : the machine-readable representation of generic structures.

    The nature of the generic chemical structures found in patents is described, with a discussion of the types of statement commonly found in them. The available representations for such structures are reviewed, with particular note being given to the suitability of the representation for searching files of such structures. Requirements for the unambiguous representation of generic structures in an "ideal" storage and retrieval system are discussed. The basic principles of the theory of formal languages are reviewed, with particular consideration being given to parsing methods for context-free languages. The Grammar and parsing of computer programming languages, as an example of artificial formal languages, is discussed. Applications of formal language theory to chemistry and information work are briefly reviewed. GENSAL, a formal language for the unambiguous description of generic structures from patents, is presented. It is designed to be intelligible to a chemist or patent agent, yet sufficiently ABSTRACT formaLised to be amenabLe to computer anaLysis. DetaiLed description is given of the facilities it provides for generic structure representation, and there is discussion of its Limitations and the principLes behind its design. A connection-tabLe-based internaL representation for generic structures, caLLed an ECTR <Extended Connection TabLe Representation) is presented. It is designed to represent generic structures unambiguousLy, and to be generated automatically from structures encoded in GENSAL. It is compared to other proposed representations, and its implementation using data types of the programming Language PascaL described. An interpreter program which generates an ECTR from structures encoded in a subset of the GENSAL Language is presented. The principles of its operation are described. Possible applications of GENSAL outside the area of patent documentation are discussed, and suggestions made for further work on the development of a generic structure storage and retrieval system based on GENSAL and ECTRs

    The Monty Hyams Archive: A New Resource in Information Science History

    Get PDF
    The Monty Hyams Archive stands as an important source of information history. This project seeks to organise and investigate the contents of the Archive while providing information on standards application to the care of the Archive. Through the research methodologies of literary warrant analysis, documentary analysis, and historical research, this dissertation proposed standards for future care of the archive, inspected the documents, and evaluated their contents and assigned descriptions. Interviews and historical research were used to expand on the information found in the documents. The descriptions generated were used to discern the major themes within the Archive and to develop an argument for The Monty Hyams as a crucial information science and patent information history resource. The project resulted in the description of the Archive’s contents, a proposed framework of standards with which to care for the Archive, and a confirmation of the argument that The Monty Hyams Archive exists as an important source of information history
