functional model of IRS

FUNCTIONAL MODEL OF IRS
As every IRS consists of a set of documents a set of queries and mechanisms to determine which of the documents are requirements of queries to begin with documents are first represented by a set of subject terms using classification or indexing language. The queries are also converted in to a representation consisting of elements of indexing language. The mapping of documents to the indexing language may be carried out manually, automatically or by combination the two processes. The mapping is known as indexing process. The indexing language is either pre-specified or taken freely from the text of the documents and queries .a particular method used to represent the individual document and query is less important than the actual choice of the elements of the indexing language made during the indexing and text analysis processes.

law of impartiality

Definition: The principle that between two or more claimants say, for the first position among two facets of a subject, or for the choice to be made from among the needs of different groups of readers preference of any one should be made only on sufficient grounds and not arbitrarily. 1. sequence of the facets: The determination of the sequence of facets in different subjects should not be left to be determined ad-hoc in each subject. On the other hand if their sequence is determined by some guiding priniciples of a general nature applicable to all subjects, the law of impartiality will be satisfied. Some may hold that another ground for deciding the sequence of facets is the relative numerousness of the readers, who’s needs will be satisfied by the different sequences 2. Empty Digit in CC : From the very first edition of Colon Classification, the digit ‘9’ as been used for long as an empty or sectorising digit. But the law of impartiality has been always suggesting a similar thing being done also in the other species of digits viz, Roman smalls and roman capitals. This suggestion has now been implemented 3. Connecting Digit in CC : From 1952 to 1963 different distinctive digits were used for the three kinds of facets personality, matter and energy-but the same one for two kinds of facets space and time. This was done because punctuation marks were used as connecting digits and there were only four such marks. The law of impartiality had been pointing to this fault all along. At last, it was satisfied in 1963 by using the single inverted comma for first facet
