....hosts retain replicas of the trees they were sharing while connected, and continue to be able to access and modify the data. When the two hosts reconnect, the two di#erent, possibly conflicting, replicas need to be reconciled. Xmiddle exploits the tree di#erencing techniques developed in [72] to detect di#erences between the replicas which hosts use to concurrently and o# line modify the shared data. However, it may happen that the a. b. HostA HostB HostC HostA HostB HostC Fig. 13. a. Host HB and Host HC are not connected. b. Host HB and Host HC connect and Host HB receives a ....

....can be represented by an ordered labeled tree (see [Wat95] and [Gus97] Thus, the secondary structure comparison, for which the pseudo knots are not taken into account, can be reduced to a tree comparison. For a few years, many ordered labeled tree comparison algorithms have been developed (see [Tai79], Kle98] These algorithms were introduced by S. M. Selkow [Sel77] and are based on the notion of edit distance or alignment score, which have since become a classical approach in the frame of sequence comparison (see [WF74] Notice that these two notions which are equivalent in the case of ....

....Each basic transformation has a cost, which is provided by a domain expert and or the user: Definition 3 (Basic cost) A basic cost is a natural number. In Section 4.4, we shall discuss several possibilities to assign costs to basic transformations. In contrast to the tree edit distance [Tai79] we do not allow arbitrary sequences of insert, delete, and rename operations. We restrict the basic transformations in order to generate only queries that have an intuitive semantics. For example, it is not allowed to delete all leaves of the original query, since every leaf captures ....
....relaxations and enforcements of query transformations (see Section 5) 8. Related Work Our work has three related areas: distance metrics for trees, query languages for XML, and structured queries in information retrieval. Several measures for the similarity of trees have been developed [Tai79, JWZ94] Our approach is di#erent concerning its semantics and concerning its computational complexity. We believe that the nodes of a tree shaped query pattern should be treated di#erently: Leaf nodes specify the information the user is looking for. The root node defines the scope of the search. ....

....tree, several results may exist, and several embeddings may lead to the same result. Figure 2 shows an embedding of a query tree into a data tree. Approximate tree embedding is based on the query transformations renaming, insertion, and deletion of nodes. In contrast to the tree edit distance [Tai79], we do not allow arbitrary sequences of basic transformations. The main purposes of these restrictions are (1) to generate only queries that are semantically useful, and (2) to avoid combinatorial e#ects that make the problem NP hard [AG97] Renaming: Renaming nodes means changing the context ....
