lbsFindDuplicateTitles: Find documents to be merged (**EXPERIMENTAL**)

Description

Indicates, by finding similarities between documents' titles, groups of documents that possibly should be merged.

Usage

lbsFindDuplicateTitles(conn, surveyDescription = NULL,
  ignoreTitles.like = NULL, aggressiveness = 1)

Arguments

conn

connection object, see lbsConnect.

surveyDescription

character string or NULL; survey description to restrict to or NULL.

ignoreTitles.like

character vector of SQL-LIKE patterns to match documents' titles to be ignored or NULL.

aggressiveness

nonnegative integer; 0 for showing only exact matches; the higher the value, the more documents will be proposed.

Value

• A numeric vector of user-selected documents' identifiers to be removed.

Details

The function determines fuzzy similarity measures of the titles. Its specificity is controlled by the aggressiveness parameter.

Search results are presented in a convenient-to-use graphical dialog box. The function tries to order the groups of documents according to their relevance (**EXPERIMENTAL** algorithm). Note that the calculation often takes a few minutes!

The ignoreTitles.like parameter determines search patterns in an SQL LIKE format, i.e. an underscore _ matches a single character and a percent sign % matches any set of characters. The search is case-insensitive.
