OReFiL is a search system for online resources that are cited in peer-reviewed papers.
This movie will introduce how to use OReFiL using the MeSH terms (MeSH terms are keywords that are assigned to medical papers).
Click “OReFiL”.
There is a search box to enter keyword(s).
Let’s try “riken genome”.
Check this box to show only those web resources whose webpage can be found.
Checking this box increases the accuracy of the search result, but also increases the search time.
Click.
When two or more words are entered as query terms, OReFiL lists the web resources by the probability of the query terms being contained. (probabilistic inference is used)
To use the AND operator, insert the query terms inside the brackets of #band().
Search.
When the AND operator is used OReFiL does not use probabilistic inference to display the search results. (i.e. an optimal search result may not necessary be available)
For exact phrase matches, insert the query terms inside the brackets of #1().
Search.
In order to include certain words (MUST words) in the search result, use #filreq . The following is an example.
The search result displays a list of MeSH terms. We will use the MeSH list to specify the MUST word(s).
The search result displays a list of online resources and related information on the left part of the page and a list of MeSH terms on the right hand of the page.
MeSH terms listed here are those from MEDLINE abstracts that cite the hit online resource.
The font size of the MeSH terms reflects each term’s frequency among the MEDLINE abstracts.
Let’s search for online resources related to “riken genome” from papers that contain the MUST words, ”Gene Expression Profiling”.
To choose a term, click it.
Terms can be searched using the search box.
Click.
A complex query term is automatically generated in the search box.
The search result displays online resources that are highly related to “riken genome” among papers that contain the MUST words, “Gene Expression profiling”..
Click.
A database named READ is displayed at the top of the search result.
The popularity of an online resource can also be checked.
Click “Show details”.
Clicking the link shows how many web pages link to the resource, using popular web page search systems such as Google.
