| 64 | <h3><a id="sec_1">What is OReFiL?</a></h3> |
|---|
| 65 | <p>OReFiL stands for <i><b>O</b>nline <b>Re</b>source <b>Fi</b>nder for <b>L</b>ifescience</i>. |
|---|
| 66 | It facilitates a search for online resources that are introduced in peer-reviewed papers. |
|---|
| 67 | You can search by MeSH terms or author names in addition to free words. |
|---|
| 68 | OReFiL extracts all URLs from MEDLINE abstracts and PubMed-indexed BioMed Central full-papers (implementation or availability sections), and indexes them with MeSH terms and author names.</p> |
|---|
| 69 | <h3><a id="sec_2">What is the benefit of using OReFiL?</a></h3> |
|---|
| 70 | <ol> |
|---|
| 71 | |
|---|
| 72 | <li>OReFiL returns up-to-date query-relevant online resources that is introduced in peer-reviewed papers.</li> |
|---|
| 73 | <li>Users can search for online resources not only by free words, but also by MeSH terms or author names.</li> |
|---|
| 74 | <li>Users can easily verify each hit resource by following the links to its corresponding PubMed entry, webpages having a link to that of the hit resource, or papers citing it through the search systems of BioMed Central, Scirus, HighWire Press, or Google Scholar.</li> |
|---|
| 75 | <li>Users can quickly confirm the existence of an online resource webpage.</li> |
|---|
| 76 | </ol> |
|---|
| 77 | |
|---|
| 78 | <h3>Tips</h3> |
|---|
| 79 | <ul> |
|---|
| 80 | <li> |
|---|
| 81 | |
|---|
| 82 | <span style="font-size:1.5em">Q</span>uery can be any keywords. |
|---|
| 83 | Each keyword can be modified to specify a context by adding the following modifiers after it: |
|---|
| 84 | <ul> |
|---|
| 85 | <li><b>.tiab</b> for titles and abstracts (<i>e.g.</i>,<span class="quote"><a href="http://orefil.dbcls.jp/search?query=apoptosis.tiab&count=50&sort_by=relevance&hide_unfetched=on">apoptosis.tiab</a></span>),</li> |
|---|
| 86 | <li><b>.auth</b> for author names, and</li> |
|---|
| 87 | <li><b>.mesh</b> / <b>.majr</b> / <b>.noexp</b> for MeSH terms.</li> |
|---|
| 88 | </ul> |
|---|
| 89 | |
|---|
| 90 | An example is <span class="quote"><a href="http://orefil.dbcls.jp/search?query=Proteins.mesh&count=50&sort_by=relevance&hide_unfetched=on">Proteins.mesh</a></span> |
|---|
| 91 | (a mesh term followed by ".mesh" is for all kinds of MeSH headers, |
|---|
| 92 | by ".majr" for those of MeSH headers of major topics with semantic expansion, |
|---|
| 93 | or ".noexp" for those without semantic expansion). |
|---|
| 94 | </li> |
|---|
| 95 | <li> |
|---|
| 96 | <span style="font-size:1.5em">A</span> multiword keyword can be expressed using the <b>#1</b> operator with parentheses such as <span class="quote"><a href="http://orefil.dbcls.jp/search?query=%231%28text+mining%29&count=50&sort_by=relevance&hide_unfetched=on">#1(text mining)</a></span> or <span class="quote"><a href="http://orefil.dbcls.jp/search?query=%231%28Sequence+Analysis%29&count=50&sort_by=relevance&hide_unfetched=on">#1(Sequence Analysis)</a></span>. |
|---|
| 97 | </li> |
|---|
| 98 | <li> |
|---|
| 99 | <span style="font-size:1.5em">B</span>oolean <b>"AND"</b> operator can be used using the <b>#band</b> operator with parentheses such as <span class="quote"><a href="http://orefil.dbcls.jp/search?query=%23band%28pathway+apoptosis%29&count=50&sort_by=relevance&hide_unfetched=on">#band(pathway apoptosis)</a></span>. |
|---|
| 100 | </li> |
|---|
| 101 | <li> |
|---|
| 102 | <span style="font-size:1.5em">B</span>oolean-AND-like language-model-based search can be done using the <b>#filreq</b> operator with parentheses such as <span class="quote"><a href="http://orefil.dbcls.jp/search?query=%23filreq%28Software.noexp+%231%28sequence+analysis%29%29&count=50&sort_by=relevance&hide_unfetched=on">#filreq(Software.noexp #1(sequence analysis))</a></span>. |
|---|
| 103 | In this example, OReFiL only considers those resources whose MEDLINE entries have the MeSH term "Software" and rank them according to the query #1(sequence analysis). |
|---|
| 104 | </li> |
|---|
| 105 | <li> |
|---|
| 106 | |
|---|
| 107 | <span style="font-size:1.5em">P</span>unctuations are ignored. So, "Databases, Protein" and "Databases Protein" are identical. |
|---|
| 108 | </li> |
|---|
| 109 | <li> |
|---|
| 110 | <span style="font-size:1.5em">N</span>on-alpha-numericals except for query operations are ignored. For example, "Variation (Genetics)" and "Variation Genetics" are identical. |
|---|
| 111 | </li> |
|---|
| 112 | <li> |
|---|
| 113 | <span style="font-size:1.5em">T</span>his system uses Lemur Toolkit (Indri), and the query language can be learned <a href="http://www.lemurproject.org/lemur/IndriQueryLanguage.php">here</a>. |
