Benchmarking approaches for ontology merging is challenging and has received little attention so far. A key problem is that there is in general no single best solution for a merge task and that merging may either be performed symmetrically or asymmetrically. As a first step to evaluate the quality of ontology merging solutions we propose the use of general metrics such as the relative coverage ...

We address the problem of refactoring existing, closely related products into product line representations. Our approach is based on comparing and matching artifacts of these existing products and merging those deemed similar while explicating those that vary. Our work focuses on formal specification of a product line refactoring operator called merge-in that puts individual products together i...

In-place and merge-based index maintenance are the two main competing strategies for on-line index construction in dynamic information retrieval systems based on inverted lists. Motivated by recent results for both strategies, we investigate possible combinations of in-place and merge-based index maintenance. We present a hybrid approach in which long posting lists are updated in-place, while s...

Information about objects that split or merge is often generated dynamically as a by-product of computation or in the observation of real-world behavior. Visualization tools for such processes must not only reveal temporal patterns and spatial organization but should also accommodate on-the-fly generation of split-merge information. This paper develops a formal structure for split-merge process...

We propose an analysis framework to investigate different flow quantities such as vorticity, λ2 or the acceleration magnitude along vortex merge graphs and within their regions of influence. The explicit extraction of vortex merge graphs enables the application of statistical tools to investigate the vortex core lines themselves. The analysis tool provides common plots as scatter plots and para...

The goal of a generative syntactic module is to create linguistic objects that connect sound to meaning. Therefore, a basic structure building operation is needed that combines syntactic objects into more complex objects. In the Minimalist Program (Chomsky 1995) this operation is called Merge. At first sight, both the existence and the working of Merge are close to being trivial, but on nearer ...

As a follow-up to previous research on software in-house integration, we have studied a case where integration has been achieved by means of developing and reusing components of the system from previously two separate systems. As an important part of this research, a number of interviews with people from an industrial project have been carried out. The present report describes the methodology u...

In the Minimalist Program (Chomsky 1995), Merge is a set operation that imposes no intrinsic ordering among its members. However, syntactic structures are linearized into strings of words at PF. This paper proposes that in order for a Merger set to be linearized, its members must be either hierarchically displaced or morphologically fused into a single terminal node. The empirical study focuses...

A hardware sort-merge system which can sort large files rapidly is proposed. It consists of an initial sorter and a pipelined merger. In the initial sorter, record sorting is divided into two parts: key-pointer sorting and record rearranging. The pipelined merger is composed of several intelligent disks each of which has a simple processor and some buffers. The hardware sortmerge system can sor...
