There is a web demo system called ICTCLAS (Institute of Computing Technology, Chinese Lexical Analysis System). It was developed by the Institute of Computing Technology, Chinese Academy of Science.

There is also a web demo system from THULAS (Tsinghua University - Lexical Analyzer for Chinese), which was developed by the Nature Language Processing Group, Tsinghua University.

NOTE: I don't know (and I cannot test) whether these site can be accessed freely across the world.
NOTE2: As with any software language tool, take the results with a grain of salt, they aren't perfect.

Both links do not seem to work. – Village Dec 26 '11 at 06:39
@Village: Oh my god, I'm sorry for that ... – fefe Dec 26 '11 at 08:02
Oh, the first one is working now. Maybe I just need to wait for the other to work. – Village Dec 26 '11 at 08:26
@Village Really ... I cannot access the first now. I'll keep an eye on it. The first one has also a downloadable demo version. – fefe Dec 26 '11 at 08:33

just write the word on google, then type definition after example: run definition Then a big box with the definition will appear, usually the first one shows what part of speech it is

Update:

Tencent NLP

Bonson NLP

There are many lexical analyzers for Chinese, but these are not developed for daily use, the typical usage is Chinese searcher engine.

I found 语言云 has a online demo, I test it by enter a sentence from today news,

"北京时间2月27日凌晨1点，FIFA特别代表大会选举中，因凡蒂诺击败萨尔曼、阿里王子、尚帕涅，成功当选新任国际足联主席，瑞士人的任期至2019年。"

The default result seems complicate, I deselected "语义依存分析" and "语义角色标注".

These tool can not be 100% accurate, for example, "选举" in the sentence is a noun, not verb ( so the SBV relation is also wrong, SBV means subject-verb), the biggest mistake is it split 因凡蒂诺(Sorry, Mr.Infantino) to 因 and 凡蒂诺.

These errors are understandable, it is still helpful.
