[Improving the retrieval of information from scientific research works in the field of medical roentgenoradiology]. / Sovershenstvovanie informatsionnogo obespecheniia nauchno-issledovatel'skikh rabot po meditsinskoi rentgenoradiologii.

A subject thesaurus covering investigations pursued at the Moscow Research Institute of Roentgenoradiology (Ministry of Health of the RSFSR) has been worked out for data retrieval. Each subject heading is provided with indices of the International Classification of Inventions (MCI), national classifications of inventions (NCI), Universal Digital Classification (UDC), Branch Automated System of Scientific Medical Information (BASSMI), Medinform, and the State Automated System of Scientific-Technical Information (SASSTI). The subject thesaurus is necessary for the detection of relevant information in the BASSMI and Medinform data banks and in patent forms.

[Development of a provisional information-retrieval descriptor language for "Roentgenology and Medical Radiology" for use in the Medinform system]. / Sovershenstvovanie deskriptornogo informatsionno-poiskovogo iazika po probleme "Rentgenologiia i radiologiia meditsinskaia" dlia ispol'zovaniia ego v sisteme "Medinform"

A problem information retrieval thesaurus consisting of descriptor and nondescriptor articles in alphabetic order was developed. It was conformed to and conjugated with the thesaurus in the field. Examples of descriptor and nondescriptor articles of the revised problem thesaurus were cited. The entire medical roentgenoradiology in the thesaurus in the field was represented by 20 descriptors. The problem thesaurus comprised approximately 1000 descriptors. The authors emphasized the role of the information retrieval thesaurus in which descriptors were renewed from an array of quasidescriptors every 3-5 yrs. The problem thesaurus is an element of the information retrieval language of the Medinform system intended for information support of specialists in roentgenoradiology.
