We are now developing a system, called blogWatcher, that tries to automatically collect and monitor Japanese blog collections of that include not only ones made with blog softwares but also ones written as normal web pages.

Furthermore, our system also extracts and mines useful information from the collected blog pages. Trend analysis is performed in the collection. Degree of `burstiness' is computed for words, and a `hot' keywords list that reflects the popular topics in a certain period is generated from the collection. Subjective(evaluative) expressions in blog entries can also be automatically annotated and highlighted in our system.

PRESRI is a supporting system for survey of academic papers. You can search for papers (ps or pdf files) on WWW.
