With click-through data analysis, we proposed an automatic search engine performance evaluation method. This method generates navigational type query topics and answers automatically(More)
We participate in document search and expert search of Enterprise Track in TREC2007. The motive behind the TREC Enterprise Track is to study the issues searching the documents and experts inside an enterprise environment, which has not been sufficiently addressed in research. In document search, we focus on the key overview page pre-selection methods and(More)
IR group of Tsinghua University participated in the expert finding task of TREC2005 enterprise track this year.

While Ajax-based programming enables faster performance and higher interface quality over pure server-side programming, it is demanding and error prone as each action that partially updates the page requires custom, ad-hoc code. The problem is exacerbated by distributed programming between the browser and server, where the developer uses JavaScript to(More)
Implementing even a conceptually simple web application requires an inordinate amount of time. FORWARD addresses three problems that reduce developer productivity: (a) Impedance mismatch across the multiple languages used at different tiers of the application architecture. (b) Distributed data access across the multiple data sources of the application (user(More)
The FORWARD project, as well as its app2you predecessor , is a Do-It-Yourself web application platform that enables non-programmers to create custom forms-driven work-flow applications, where users with potentially different roles and rights interact. Our experience with the commercialized version of app2you (app2you.com) shows that forms-driven workflow(More)
