Sažetak
In this paper we deal with problem of addition of new documents in collection when documents are represented in lower dimensional space by concept indexing. Concept indexing is a method of feature construction that is relying on concept decomposition of term-document matrix. This problem is especially interesting for application on World Wide Web. Proposed methods are tested for the task of information retrieval. Vectors on which the projection is done in the process of dimension reduction are constructed on the base of representations of all documents in the collection, and computation of the new representations in the space of reduced dimension demands recomputation of concept decomposition. The solution of this problem is development of methods which will give approximate representation of newly added documents in the space of reduced dimension.
