88 | <h3><a id="sec_1">What is OReFiL?</a></h3> |
---|
89 | <p>OReFiL stands for <i><b>O</b>nline <b>Re</b>source <b>Fi</b>nder for <b>L</b>ifescience</i>. |
---|
90 | It facilitates a search for online resources that are introduced at peer-reviewed papers. |
---|
91 | You can search by MeSH terms or author names in addition to free words. |
---|
92 | OReFiL extracts all URLs from MEDLINE abstracts and PubMed-indexed BioMed Central full-papers (implementation or availability sections), and indexed them with MeSH terms and author names.</p> |
---|
93 | <h3><a id="sec_2">What is the benefit of using OReFiL?</a></h3> |
---|
94 | <ol> |
---|
95 | <li>OReFiL returns up-to-date query-relevant online resources that is introduced in peer-reviewed papers.</li> |
---|
96 | <li>Users can search for online resources not only by free words, but also by MeSH terms or author names.</li> |
---|
97 | <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> |
---|
98 | <li>Users can quickly confirm the existence of an online resource webpage.</li> |
---|
99 | </ol> |
---|

---|
101 | <h3>Tips</h3> |
---|
102 | <ul> |
---|
103 | <li> |
---|
104 | <span style="font-size:1.5em">Q</span>uery can be any keywords. |
---|
105 | Each keyword can be modified to specify a context by adding the following modifiers after it: |
---|
106 | <ul> |
---|
107 | <li><b>.tiab</b> for titles and abstracts (<i>e.g.</i>,<span class="quote">apoptosis.tiab</span>), |
---|
108 | <li><b>.auth</b> for author names, and |
---|
109 | <li><b>.mesh</b> / <b>.majr</b> / <b>.noexp</b> for MeSH terms. |
---|
110 | </ul> |
---|
111 | An example is <span class="quote">Proteins.mesh</span> |
---|
112 | (a mesh term followed by ".mesh" is for all kinds of MeSH headers, |
---|
113 | by ".majr" for those of MeSH headers of major topics with semantic expansion, |
---|
114 | or ".noexp" for those without semantic expansion). |
---|
115 | <li> |
---|
116 | <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">#1(text mining)</span> or <span class="quote">#1(Sequence Analysis)</span>. |
---|
117 | <li> |
---|
118 | <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">#band(pathway apoptosis)</span>. |
---|
119 | <li> |
---|
120 | <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">#filreq(Software.noexp #1(sequence analysis))</span>. |
---|
121 | 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). |
---|
122 | <li> |
---|
123 | <span style="font-size:1.5em">P</span>unctuations are ignored. So, "Databases, Protein" and "Databases Protein" are identical. |
---|
124 | <li> |
---|
125 | <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. |
---|
126 | <li> |
---|
127 | <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>. |
