Abstract
Lore (for Lightweight Object Repository) is a DBMS designed specifically for managing semistructured information. Implementing Lore has required rethinking all aspects of a DBMS, including storage management, indexing, query processing and optimization, and user interfaces. This paper provides an overview of these aspects of the Lore system, as well as other novel features such as dynamic structural summaries and seamless access to data from external sources.

Exploiting structure for intelligent Web search

TL;DR: The internal document structure is being used to extract concepts which impose a directory-like structure on the documents, similar to those found in classified directories, in an efficient way which is largely language independent and does not make assumptions about the document structure.

The START Multimedia Information System: Current Technology and Future Directions.

TL;DR: Start, a natural language question answering system that provides users with high-precision multimedia information access through the use of natural language annotations, and Omnibase, which assists Start by integrating structured and semistructured Web databases into a single, uniformly structured “virtual database.”

OrientStore: a schema based native XML storage system

TL;DR: This chapter discusses a schema based native XML storage system, and an evaluation of the alternative non-native storage strategies is presented.

XEM: XML Evolution Management

TL;DR: The first solution framework, called XML Evolution Manager (XEM), to manage the evolution of DTDs and XML documents is put forth, which improves upon the previous method of making manual changes and reloading data from scratch by providing automated evolution management facilities.

Query evaluation techniques for large databases

TL;DR: This survey describes a wide array of practical query evaluation techniques for both relational and postrelational database systems, including iterative execution of complex query evaluation plans, the duality of sort- and hash-based set-matching algorithms, types of parallel query execution and their implementation, and special operators for emerging database application domains.

The Lorel Query Language for Semistructured Data

TL;DR: The main novelties of the Lorel language are the extensive use of coercion to relieve the user from the strict typing of OQL, which is inappropriate for semistructured data; and powerful path expressions, which permit a flexible form of declarative navigational access and are particularly suitable when the details of the structure are not known to the user.
