Building a search engine that can scale to billions of documents while satisfying the needs of the users presents serious challenges. Few successful stories have been reported so far [36]. Here, we report our experience in building YouSeer, a complete open source search engine tool that includes both an open source crawler and an open source indexer. Our approach takes other open source compone...

The rapidly increasing quantity and diversity of data stored on our PCs made locating information in this environment very difficult. Consequently, recent research has focussed on building semantically enhanced systems for either organizing or searching data on the desktop. Building on previous work, in this paper we present the Beagle toolbox, a set of extendable building blocks for implementi...

Many software libraries (e.g., the Booch C++ Components, libg++, NIHCL, COOL) provide components (classes) that implement data structures. Each component is written by hand and represents a unique combination of features (e.g. concurrency, data structure, memory allocation algorithms) that distinguishes it from other components. We argue that this way of building data structure component librar...

Component Based Software Development is carried out in two phases: Component Building and Application Assembly. The key to building business components is a formal approach for identifying the components. This paper describes such an approach, which assists in identifying the components from an Analysis Level Object Model, representing a business domain. The approach makes use of a clustering a...

Building product models are beginning to find their way into AEC practice. They are proving useful for coordinating large multidisciplinary design and construction teams. In an evolving design and construction planning process, building components are added, modified, or deleted from the product model, causing important spatial relationships to emerge. In addition, new criteria can emerge throu...
