Usenet dynamic indexed info source DynamicIndexedInfoSource The collection of <a href="http://sw.opencyc.org/concept/Mx4rwD_r7ZwpEbGdrcN5Y29ycA" class="cyc_term">IndexedInformationSource</a>s for which the associated indexing may change over time. For each <a href="http://sw.opencyc.org/concept/Mx4rwD_r7ZwpEbGdrcN5Y29ycA" class="cyc_term">IndexedInformationSource</a>, and for each time, there is a characteristic function associating index terms with the pieces of information indexed by that <a href="http://sw.opencyc.org/concept/Mx4rwD_r7ZwpEbGdrcN5Y29ycA" class="cyc_term">IndexedInformationSource</a> (see <a href="http://sw.opencyc.org/concept/Mx4rvViBCZwpEbGdrcN5Y29ycA" class="cyc_term">comment</a> on <a href="http://sw.opencyc.org/concept/Mx4rwD_r7ZwpEbGdrcN5Y29ycA" class="cyc_term">IndexedInformationSource</a>). For any <a href="http://sw.opencyc.org/concept/Mx4rwBcktpwpEbGdrcN5Y29ycA" class="cyc_term">DynamicIndexedInfoSource</a>, the indexing of information may change over time. Each <a href="http://sw.opencyc.org/concept/Mx4rwBcktpwpEbGdrcN5Y29ycA" class="cyc_term">DynamicIndexedInfoSource</a> is such that it may have various characteristic functions over the course of its existence. This can happen in several ways: New information is added to the source and is indexed by some new terms; the index terms and information in the source remain the same, but the indexing changes; information or terms are removed from the source. The OED, considered as a single work that has been modified over time, is an example of an <a href="http://sw.opencyc.org/concept/Mx4rwBcktpwpEbGdrcN5Y29ycA" class="cyc_term">DynamicIndexedInfoSource</a> -- the amount of information (the number of definintions) in this source has increased, and the number of index terms (the number of words defined) has also increased. Another example is the <a href="http://sw.opencyc.org/concept/Mx4rvWQvpJwpEbGdrcN5Y29ycA" class="cyc_term">WorldWideWeb_DynamicIndexedInfoSource</a>. This <a href="http://sw.opencyc.org/concept/Mx4rwBcktpwpEbGdrcN5Y29ycA" class="cyc_term">DynamicIndexedInfoSource</a> associates, at a given time, certain peices of information (web pages) with certain addresses (URLs). At a later time it may associate a new web page with a previously unused URL, or it may associate an existing web page with a URL previously used for a different web page.
