SimRank: a measure of structural-context similarity
A complementary approach, applicable in any domain with object-to-object relationships, that measures similarity of the structural context in which objects occur, based on their relationships with other objects is proposed.
The CQL continuous query language: semantic foundations and query execution
This paper presents the structure of CQL's query execution plans as well as details of the most important components: operators, interoperator queues, synopses, and sharing of components among multiple operators and queries.
Models and issues in data stream systems
The need for and research issues arising from a new model of data processing, where data does not take the form of persistent relations, but rather arrives in multiple, continuous, rapid, time-varying data streams are motivated.
Scaling personalized web search
The approach enables incremental computation, so that the construction of personalized views from partial vectors is practical at query time, and experimental results demonstrate the effectiveness and scalability of the techniques.
DataGuides: Enabling Query Formulation and Optimization in Semistructured Databases
The theoretical foundations of DataGuides are presented along with an algorithm for their creation and an overview of incremental maintenance, and performance results based on the implementation of dataGuides in the Lore DBMS for semistructured data are provided.
GPS: a graph processing system
This paper describes the implementation of GPS and its novel features, and presents experimental results on the performance effects of both static and dynamic graph partitioning schemes, and describes the compilation of a high-level domain-specific programming language to GPS, enabling easy expression of complex algorithms.
Database Systems: The Complete Book
This introduction to database systems offers a readable comprehensive approach with engaging, real-world examples, and users will learn how to successfully plan a database application before building it.
The Lorel query language for semistructured data

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.
The TSIMMIS Project: Integration of Heterogeneous Information Sources
An overview of the Tsimmis Project is given, describing components that extract properties from unstructured objects, that translate information into a common object model, that combine information from several sources, that allow browsing of information, and that manage constraints across heterogeneous sites.
Swoosh: a generic approach to entity resolution
- Omar Benjelloun, H. Garcia-Molina, David Menestrina, Qi Su, S. E. Whang, J. Widom
- Computer ScienceThe VLDB Journal
This work formalizes the generic ER problem, treating the functions for comparing and merging records as black-boxes, and identifies four important properties that, if satisfied by the match and merge functions, enable much more efficient ER algorithms.
