references_internal_url_sxt because they had been shown to be
superfluous. The citation of referrer in the host browser is possible
without them. Therefore now the host browser does not only show
internal, but also external referrer to each link.
explored for citations within other documents. A click on the
'Citations' link shows an analysis with all text lines in the document
each with a complete list of documents which contain the same line. A
second section shows the linking documents in ascending order of number
of citations from the original document. Because documents from
different hosts are most interesting here, they are listed at the top of
the page as possible 'copypasta' source.
yacy will load linked web pages from search results until the total
number of web pages reaches 15000. This shall give fresh peers a 'boost'
to get faster a personalized search index.
texts, separated by sentences. Then, these sentences can be used to
search again in the index for the same sentence. This can be used to
provide a tool for plagiarism-search. (not finished yet).
Try the following:
http://localhost:8090/solr/select?q=text_t:flut&grep=wasser&defType=edismax&start=0&rows=3&core=collection1&wt=grephtml
.. to search for 'flut' and show only sentences in the result documents
which contain the word 'wasser'.
Consider this like using a grep-tool on documents: you select the
documents by a search query and you grep sentences inside the found
documents with the 'grep' attribute.
switch between p2p search and the 'stealth mode' which is simply a
non-p2p search within the p2p network. The functionality was there all
the time, but the switch to this was not very visible.
output writer. This made the creation of a html result writer necessary
which is included in this commit. The yacydoc servlet was used to
present all metadata to a document, but the solr interface can serve for
this purpose in a much better way. All usages (instead one) of yacydoc
were replaced by a solr call. This affects also the 'metadata' link
attached to search results.
function. This replaces the previous formula, which was bad. Before you
update to this version, please check if you changed the ranking function
yourself before, since it will be overwritten.
While the values for the reference evaluation are computed, also a
backlink-structure can be discovered and written to the index as well.
The host browser has been extended to show such backlinks to each
presented links. The host browser therefore can now show an information
where an document is linked. The new citation reference is computed as
likelyhood for a random click path with recursive usage of previously
computed likelyhood. This process is repeated until the likelyhood
converges to a specific number. This number is then normalized to a
ranking value CRn, 0<=CRn<=1. The value CRn can therefore be used to
rank popularity within intra-domain link structures.
- move setting of system property solr.directoryFactory=solr.MMapDirectoryFactory to solrcore.properties
- add check of os.arch for 64bit system, if it fails use default/solrcore.x86.properties (if exists) as solrcore.properties
