Comparison of some academic search egnines——by Cao Ruichuang

I tried to search some relational papers of the item "slack budgeting",which focus on retiming synchronous circuitry and lower power, from there search engines. The following is my experience.

Arnetminer:

I search key words and the engine shows me some experts in these fields. When I type the key words in the input frame, the tips below are some paper that contains the key and is of high citation number.In order to get the paper, one should follow the link to the author's home page. We could also get the contacts of the author. If you don't know the exaxt title of the paper, or just want to find papers on some one topic, or to contact the author, choose Arnetminer. By the way, the engine provides some mainstream form of reference. So if you don't use a software like Notepress, THis website will be helpful to you.

Google:

This time I search the key words and the google scholar doesn't give informations as many as I expected before. At least, less than some full-text database. But if I change the key words to the titles of papers, It gives me direct link to the paper or the download page. If it has no copyright to render download services, "help from Tsinghua" leads me to our school library to get it. In a word, google scholar is a search engine of academic articles more than academic search.

Biomedexperts: 

To tell the truth, I haven't find useful things here because I didn't find a search input frame and I don't know which experts focus on the topics. When I tried to browse key words, the classification is too meticulous for me to choose one. A good news is that we can browse author names here when meet repetition of names and don't know which of them to take. It is also a good academic search engine but not fit me when I want to find some useful papers by topics.
