Efficient insertion of approximately sorted sequences of items into a dictionary

ABSTRACT
In this paper we propose a new data structure for the classical dictionary problem, supporting efficient on-line inserting of a sequence S of keys by taking advantage of ordering relationships existing among the sorted subsequences in which S can be decomposed. More precisely, we will show that any sorted subsequences S_k of k keys contained in S can be inserted into the dictionary in O(p log n + (n - p)), where n is the size of the dictionary and p is the number of fragments in which S_k breaks up when inserted into the dictionary (where a fragment is a set of adjacent keys of S_k which maintain their adjancency into the dictionary). Some applications, as specified in the paper, specifically require for this property.
