Knowledge Organisation and Retrieval Questions and Answers

Answer: D

The keyed answer is the inverted cross reference. Of the choices it is the one the indexer builds and so controls, taking the reference in the reverse direction between related headings, whereas the others are the ordinary references (see, see also) that follow fixed conventions.

The 'see' and 'see also' (check also) forms are routine reference types that give the user direction but do not give the indexer the complete control described in the question.

Answer: B

The features of postcoordinate indexing are ii and iii: terms are coordinated by the user at the time of search, and there is no fixed citation order.

Statement i is false, as the index terms are not pre-determined but taken from the document at the time of indexing. Statement iv is false, since postcoordinate indexing makes a single entry for each document, unlike precoordinate indexing, which makes multiple entries.

Answer: D

The stages of knowledge representation in order are gather data, codification, knowledge database and content mapping, so i, iii, ii, iv.

The other orders put codification or mapping before data is gathered, or the database before codification. Data must first be gathered, then codified, then held in a database before its content can be mapped.

Knowledge representation starts with collecting the raw data, after which it is codified, stored in a knowledge database and finally its content is mapped for use, which is the sequence in the key.

Answer: D

The correct matching is a-iii, b-iv, c-i, d-ii. In MARC 21 tag 020 is the ISBN, 100 is the personal name main entry, 260 is publication and distribution, and 440 is the series statement.

The other codes swap these fields, for example making 260 the ISBN, which is wrong.

An easy way to recall these: the 0XX tags hold control and number data such as the ISBN, the 1XX tags hold main entry headings such as the personal name, the 2XX tags hold the title and imprint area, and the 4XX tags hold the series statement.

Answer: A

The keyed answer is that both statements are true. The inverse document frequency is the logarithm of the reciprocal of the share of documents that contain a given term, and the weighting measure is used together with term frequency.

The reason is loosely worded, since it is the tf-idf measure that is computed from term frequency and inverse document frequency. The official key treats it as true, and the paper followed it.

Answer: A

Both statements are true. The principle of canonical sequence says that where subjects in an array traditionally follow a sequence, it is convenient to keep that sequence, and classification schemes mainly follow it in arranging arrays.

The options calling either statement false are wrong.

The principle belongs to Ranganathan's canons for the arrangement of classes in an array, and in practice schemes of classification follow it where the order is already well established, for example the order of the months or of the planets.

Answer: D

The assertion is true and the reason is false. PANDEX is an indexing system that can change the lead term to a standard form for better collocation of terms.

The reason, that the first input string is truncated after 18 characters and the second after 11, is not the keyed fact, so the combination is A true, R false.

PANDEX is a computer based permuted indexing system and the figures given in the reason are its string limits, but the key treats the reason as not true of the way the system works, so the assertion alone stands.
