Reflections on notecards: Seven issues for the next generation of hypermedia systems
- Communications of the ACM
, 1988
"... NoteCards is a general hypermedia environment designed to help people work with ideas. Its intended users are authors, designers, and other intellectual laborers engaged in analyzing information, designing artifacts, and generally processing ideas. The system provides these users with a variety of h ..."

of the major issues that must be addressed in the next generation of hypermedia systems. These seven issues are: search and query, composite nodes, virtual structures, computational engines, versioning, collaborative work, and tailorability. For each of these issues, the papers describes the limitations
Routing indices for peer-to-peer systems
, 2002
"... Finding information in a peer-to-peer system currently requires either a costly and vulnerable central index, or ooding the network with queries. In this paper we introduce the concept of Routing Indices (RIs), which allow nodes to forward queries to neighbors that are more likely to have answers. I ..."

Mercury: Supporting scalable multi-attribute range queries
- In SIGCOMM
, 2004
"... This paper presents the design of Mercury, a scalable protocol for supporting multi-attribute rangebased searches. Mercury differs from previous range-based query systems in that it supports multiple attributes as well as performs explicit load balancing. Efficient routing and load balancing are imp ..."

Rumor Routing Algorithm for Sensor Networks
, 2002
"... Advances in micro-sensor and radio technology will enable small but smart sensors to be deployed for a wide range of environmental monitoring applications. In order to constrain communication overhead, dense sensor networks call for new and highly efficient methods for distributing queries to nodes ..."

Research on Querying Node Probability Method in Probabilistic XML Data Based on Possible World
"... doi:10.4156/jdcta.vol4. issue8.26 In order to solve the low efficiency problem of directly querying single node probability in the set of all ordinary XML data obtained by enumerating possible world set of the corresponding probabilistic XML data, the method is presented that probabilistic XML data ..."

Index Structures for Path Expressions
, 1997
"... In recent years there has been an increased interest in managing data which does not conform to traditional data models, like the relational or object oriented model. The reasons for this non-conformance are diverse. One one hand, data may not conform to such models at the physical level: it may be ..."

be simply specified by a schema which is too complex or changes too often to be described easily as a traditional schema. The term semistructured data has been used to refer to such data. The data model proposed for this kind of data consists of an edge-labeled graph, in which nodes correspond to objects
Scalable information-driven sensor querying and routing for ad hoc heterogeneous sensor networks
- International Journal of High Performance Computing Applications
, 2002
"... This paper describes two novel techniques, informationdriven sensor querying (IDSQ) and constrained anisotropic diffusion routing (CADR), for energy-efficient data querying and routing in ad hoc sensor networks for a range of collaborative signal processing tasks. The key idea is to introduce an inf ..."

Keyword searching and browsing in databases using BANKS
- In ICDE
, 2002
"... With the growth of the Web, there has been a rapid increase in the number of users who need to access online databases without having a detailed knowledge of the schema or of query languages; even relatively simple query languages designed for non-experts are too complicated for them. We describe BA ..."

Answers to a query are modeled as rooted trees connecting tuples that match individual keywords in the query
Cartel: a distributed mobile sensor computing system
- In 4th ACM SenSys
, 2006
"... CarTel is a mobile sensor computing system designed to collect, process, deliver, and visualize data from sensors located on mobile units such as automobiles. A CarTel node is a mobile embedded computer coupled to a set of sensors. Each node gathers and processes sensor readings locally before deliv ..."

CarTel applications run on the portal, using a delaytolerant continuous query processor, ICEDB, to specify how the mobile nodes should summarize, filter, and dynamically prioritize data. The portal and the mobile nodes use a delaytolerant network stack, CafNet, to communicate. CarTel has been
An optimal and progressive algorithm for skyline queries

"... The skyline of a set of d-dimensional points contains the points that are not dominated by any other point on all dimensions. Skyline computation has recently received considerable attention in the database community, especially for progressive (or online) algorithms that can quickly return the firs ..."
