In this paper, we study adaptive evaluation techniques for querying XMLbased electronic catalogs, and show, by means of experiments performed on real-world catalogs, that our approach can be used to integrate them with virtually zero effort at start-up time, and a small constant factor needed to perform the adaptive evaluation for all subsequent queries. We reach the conclusion that, from a str...

We present a catalog of 200 clusters of galaxies serendipitously detected in 647 ROSAT PSPC high Galactic latitude pointings covering 158 square degrees. This is one of the largest X-ray selected cluster samples, comparable in size only to the ROSAT All-Sky Survey sample of nearby clusters (Ebeling et al. 1997). We detect clusters in the inner 17.5 of the ROSAT PSPC field of view using the spat...

This paper addresses two major challenges of powerful meta search systems within the area of literature services: accessing services over their public Web interfaces and coping with portions of information. We start by identifying three significant classes of literature services and describe their information splitting policies. Then, we present the results of two experiments: In the first expe...

In this paper we build on recent work on case-based product recommendation focused on generating rich product descriptions for use in a recommendation context by mining user-generated reviews. This is in contrast to conventional case-based approaches which tend to rely on case descriptions that are based on available meta-data or catalog descriptions. By mining user-generated reviews we can pro...

Zusammenfassung: Das Internet wird als ein internationaler Informationsraum, an dem jeder partizipieren und von dem jeder profitieren kann, angesehen. Es wurde untersucht, inwieweit im Internet verfügbare Suchmaschinen, Online-Wörterbücher und OPAC Systeme ihre Dienste einem internationalen Nutzerkreis zugänglich machen. Der hier untersuchte Aspekt betrifft die multilinguale Recherche, bei der ...

This paper presents CATaLog online, a new web-based MT and TM post-editing tool. CATaLog online is a freeware software that can be used through a web browser and it requires only a simple registration. The tool features a number of editing and log functions similar to the desktop version of CATaLog enhanced with several new features that we describe in detail in this paper. CATaLog online is de...

Sohn et al. (2012) recently published an annotated catalog of lepidopteran fossils, which was the first attempt to compile all the known fossil specimens, described or undescribed, from the world literature. This publication provided paleontological data such as fossil type, specimen deposition, excavation locality, fossil host plants, and geological age for at least 4,568 specimens, including ...

Today’s global internetworks challenge the ability of name services and other information services to locate data quickly. We introduce a distributed active catalog and meta-data caching for optimizing queries in this environment. Our active catalog constrains the search space for a query by returning a list of data repositories where the answer to the query is likely to be found. Meta-data cac...
