An ex erimental computer program has been Beveloped to classify documents according to the 80 sections and five major section groupings of Chemical Abstracts (CA). TIhe pro&am uses pattern recognition techniques supplemented by heuristics. During the ‘training’ phase, words from pre-classified documents are selected, and the probability of occurrence of each word in-each section of CA is computed and stored in a reference dictionarv. The ‘classification’ phase matches each wdrd of a document title against the dictionary and assigns a section number to the document using weights derived from the probabilities in the dictionary. 2.

The main features of the comprehensive formatting guidlines used for creating chemical st&ture diagrams for Chemicd Abstracts Service (CAS) uublications are described. The guidelines here designed to standardize format as much as possible and to conserve column space in publications. Methods used for reducing crowding in diagrams are described. 3.

bibl. (2 ref.). Indexing quality determmes whether the information content of an indexed document is accurately represented. Indexing effectiveness measures whether an indexed document is correctly retrieved every rime it is relevant to a query. Measurement of these criteria is cumbersome and costly: database producers therefore prefer mterindexer consistency as a measure of indexing quality or effectiveness. The present article assesses the validity of this substitution in various environments. 4. CAB Abstracts: a global view. B. Cronin (ASLIB Research & Consultancy Division).

of new law abstricts

the abstracts and the abridgements of United Kingdom patent documents have been measured and compared with the readability and information content of the full text of the documents themselves. Abridgements were found more difficult to read than abstracts, whilst both types of surrogates were more difficult to read than the full text. The information content of abridgements was judged to be higher than that of abstracts. Abstracts from Chemical Abstracts and from Biological Abstracts were judged to be easier to read than either the surrogates or the full texts. 6. History of Abstracting at Chemical Abstracts Service. Dale B. Baker et al. (Chemical Abstracts Service, Columbus, Ohio). JOWMI/ of Cilemicai Irgormation anti Computer Sciences. November 1980, Vol. 20, No. 4, pp. 193-201, 6 fig., bibl. (26 ref.). The evolution of abstracts and abstracting for Chemical Abstracts (CA) from 1907 to the present is traced. The growth of scientific publishing, changes in the content, form, format. national origin. and language of primary documents, the shift from a large corps of volunteer abstracters to inhouse document analyst, and the transition to modern computer processing, have all affected the preparation and publication of CA abstracts

7. Seventh Cranfield International Conference on Mechanised Information Storage and Retrieval Systems. The potential impact of telecommunication networks on information systems intelligence. B. Mahon (Euronet Launch Team, Luxembourg). 1,~ _formation Processing und Managemfilt. 1980, Vol. 16, No. 6. pp. 305-311. 2 fig.

The impact of telecommunications technology on the information profession is reviewed. The potential for the application of ‘information intelligence’ using the considerable know-how of the information professional -- to new- technologies is exnlored. It is concluded that there is much ‘more to be gained from the application of professional knowledge to systems design than to the perfection of searching techniques on behalf of end users. 8.
