With the explosion in the amount of semi-structured data users access and store in personal information management systems, there is a need for complex search tools to retrieve often very heterogeneous data in a simple and efficient way. Existing tools usually index text content, allowing for some IR-style ranking on the textual part of the query, but only(More)
With the explosion in the amount of semi-structured data users access and store, there is a need for complex search tools to retrieve often very heterogeneous data in a simple and efficient way. Existing tools usually index text content, allowing for some IR-style ranking on the textual part of the query, but only consider structure (e.g., file directory)(More)
On the basis of analyzing the disadvantages and requirements of material supply of hydroelectric project, develops a material dispatching management information and decision support system based on both C/S model and B/S model. The three-hierarchy model and algorithm of material dispatching and the structure and function of the system are discussed in(More)
“Network Information System” has emerged as an important research field. Researchers in computer science have successfully developed some network technologies includes security solutions, information query protocols, and data management services. However, along with the development of wireless network technology, there is a need of solution(More)
The relentless growth in capacity and dropping price of storage are driving an explosion in the amount of information users are collecting and storing in personal information management systems. This explosion of information has led to a critical need for complex search tools to access often very heterogeneous data in a simple and efficient manner. Such(More)
The amount of personal data that users store and access in personal information systems has grown massively. Simple flexible search tools are a necessity for users to be able to access the data they need. In addition, the file organization that is typical in file systems is not a practical logical view anymore as applications may store information across(More)
With the explosion in the amount of semistructured data users access and store in personal information management systems, there is a critical need for powerful search tools to retrieve often very heterogeneous data in a simple and efficient way. Existing tools typically support some IR-style ranking on the textual part of the query, but only consider(More)
FLAC3D (Fast Lagrangian Analysis of Continua in 3 Dimensions), developed by Itasca Consulting Group Inc., USA, is widely used as computational package in the world. For some complex geologic problems, numerical models with FLAC3D are difficult to construct. Therefore, a fast modeling method, which consists of building complicated numerical models with(More)
User data stored in personal information systems is growing massively. Simultaneously, this data is increasingly distributed across multiple organizational domains such as email, music databases, and photo albums, some of which are structured automatically by applications. Powerful search tools are needed to help users locate data in these expanding yet(More)
