Abstract (in Japanese) (See Japanese page) 
(in English) In this paper, we consider online construction of a text index for a set $S$ of $K$ strings in the dynamic setting that
a new letter is appended to one of the strings from time to time.
First, we present an online algorithm that constructs the generalized suffix trie of $S$ in $O(N^2)$ time and space
supporting string matching query $P$ in $O(|P|)$ time, where $N$ is the total number of letters in $S$.
Next, we discuss online construction of a linear space text index based on generalized suffix trees using
Weiner's algorithms and Ukkonen's algorithm.
