While much work has been published on LSI, most of it addresses the algorithmic or theoretical basis of the model. Little, if any, presents implementation issues in practice. We describe a production-level implementation of LSI. The system integrates components including document collection and preprocessing, singular value decomposition (SVD), multilingual processing, and a tree-based access method for similarity querying. We discuss implementation issues encountered during the development of the system. In particular, we address scalability issues in the query engine and various components of the system, and present lessons learned.","PeriodicalId":368473,"journal":{"name":"Proceedings Eleventh International Workshop on Research Issues in Data Engineering.

Nevertheless, their practical use still shows some severe deficiencies. We show that these shortcomings can optimally be overcome when leveraging both techniques on each other.

{"title":"Scalable distributed query and update service implementations for XML document elements","authors":"T. Grabs, Klemens Böhm, H. Schek","doi":"10.1109/RIDE.2001.916489","DOIUrl":"https://doi.org/10.1109/RIDE.2001.916489","url":null,"abstract":"Materialization and indexing of XML views is an important issue, and a number of 'XML-to-RDBMS' mappings have been proposed. To build a scalable system for XML document storage where those views are up-to-date, our approach is to provide efficient implementations of basic services for query processing and updates. As a first contribution we define such services, and show that they support many 'XML-to-RDBMS' mappings. As a second contribution, we describe implementations of such services in a database cluster. We evaluate two implementations, one based on a two-level logging and isolation mechanism and one using Windows 2000 COM+ transactions. The main results are as follows: the first approach scales linearly for updates, and query response times are interactive. For example, with high workloads of 100 concurrent clients and 8 cluster components, query response times are 3 seconds on average. The alternative approach is weaker both regarding query response times (10 seconds on average for the above scenario) and scalability.","PeriodicalId":368473,"journal":{"name":"Proceedings Eleventh International Workshop on Research Issues in Data Engineering.
