bayesian filters. This can be used to classify documents during
indexing-time using a pre-definied bayesian filter.
New wordings:
- a context is a class where different categories are possible. The
context name is equal to a facet name.
- a category is a facet type within a facet navigation. Each context
must have several categories, at least one custom name (things you want
to discover) and one with the exact name "negative".
To use this, you must do:
- for each context, you must create a directory within
DATA/CLASSIFICATION with the name of the context (the facet name)
- within each context directory, you must create text files with one
document each per line for every categroy. One of these categories MUST
have the name 'negative.txt'.
Then, each new document is classified to match within one of the given
categories for each context.
- date navigation
The date is taken from the CONTENT of the documents / web pages, NOT
from a date submitted in the context of metadata (i.e. http header or
html head form). This makes it possible to search for documents in the
future, i.e. when documents contain event descriptions for future
events.
The date is written to an index field which is now enabled by default.
All documents are scanned for contained date mentions.
To visualize the dates for a specific search results, a histogram
showing the number of documents for each day is displayed. To render
these histograms the morris.js library is used. Morris.js requires also
raphael.js which is now also integrated in YaCy.
The histogram is now also displayed in the index browser by default.
To select a specific range from a search result, the following modifiers
had been introduced:
from:<date>
to:<date>
These modifiers can be used separately (i.e. only 'from' or only 'to')
to describe an open interval or combined to have a closed interval. Both
dates are inclusive. To select a specific single date only, use the
'to:' - modifier.
The histogram shows blue and green lines; the green lines denot weekend
days (saturday and sunday).
Clicking on bars in the histogram has the following reaction:
1st click: add a from:<date> modifier for the date of the bar
2nd click: add a to:<date> modifier for the date of the bar
3rd click: remove from and date modifier and set a on:<date> for the bar
When the on:<date> modifier is used, the histogram shows an unlimited
time period. This makes it possible to click again (4th click) which is
then interpreted as a 1st click again (sets a from modifier).
The display feature is NOT switched on by default; to switch it on use
the /ConfigSearchPage_p.html servlet.
tested with IE11 and Firefox 32 (change worked for both to show 2nd line without cutting off height)
+fix charset parameter in metadataImageParser
+update start errMsgTxt to "java 1.7"
- added order option to solr queries to be able to retrieve document
lists in specific order, here: link length
- added HyperlinkEdge class which manages the link structure
- integrated the HyperlinkEdge class into clickdepth computation
- extended the linkstructure.json servlet to show also the clickdepth
and other statistic information
- added a servlet api/linkstructure.json which generates a link graph
information in json
- added a javascript link graph renderer hypertree.js using d3 and the
new servlet linkstructure.json
- embedded the new link graph in the crawler monitor and the host
browser
- removed 'worker' processes
- no internal time-out behaviour: methods either are successful or
return null
- waiting is only done on top-level
- removed snippet-production; this is replaced by solr snippets
- removed statistics based on solr size queries (they had been VERY
long); the statistics (like suggestions or tag cloud) are now again
based on the old but very fast RWI index. In portal or intranet mode the
RWI index is usually switched off; if you like to have statistics again
then you must switch on the rwis again in this mode.
- fixed many bugs regarding correct page counter
The default schema uses only some of them and the resting search index
has now the following properties:
- webgraph size will have about 40 times as much entries as default
index
- the complete index size will increase and may be about the double size
of current amount
As testing showed, not much indexing performance is lost. The default
index will be smaller (moved fields out of it); thus searching
can be faster.
The new index will cause that some old parts in YaCy can be removed,
i.e. specialized webgraph data and the noload crawler. The new index
will make it possible to:
- search within link texts of linked but not indexed documents (about 20
times of document index in size!!)
- get a very detailed link graph
- enhance ranking using a complete link graph
To get the full access to the new index, the API to solr has now two
access points: one with attribute core=collection1 for the default
search index and core=webgraph to the new webgraph search index. This is
also avaiable for p2p operation but client access is not yet
implemented.
Solr search interface in such way that it is possible to use this
interface for the yacyinteractive search. This search interface is now
much faster using the Solr search directly. For the Solr interface it
was necessary to create a translation from the YaCy search modifiers to
the Solr facet selection. This was added in such a way that it becomes
generic for the normal YaCy search and as a on-top evaluation for Solr
queries.
that enables viewing of images for intranet SMB servers.
- added a filter search for protocol, tld and ext again; otherwise p2p
search produces a lot of rubbish
- added indexing to Tables columns to support larger bookmark
collections
- added RDF output (HTTP) for public bookmarks at /YMarks.rdf
- YMarkRDF also provides a Jena RDF Model as "internal" API
- various other changes/fixes for YMarks (mainly backend)
only links where the content can be parsed. All non-parseable links are
placed into the noload queue. The search process must therefore be able
to filter out non-text search results.
- This fixes the problem that image search results appeared in the text
search.
- The interactive search can retrieve now ALL types of links
- The p2p interface is now extended to retrieve only certain types of
links (text, image, video, apps)
- The search process has an extension to filter the right document type
according to the search query
ready-prepared crawl list but at the stacks of the domains that are
stored for balanced crawling. This affects also the balancer since that
does not need to prepare the pre-selected crawl list for monitoring. As
a effect:
- it is no more possible to see the correct order of next to-be-crawled
links, since that depends on the actual state of the balancer stack the
next time another url is requested for loading
- the balancer works better since the next url can be selected according
to the current situation and not according to a pre-selected order.
- show active/running crawls
- execute crawls (works currently only if API entry is available)
- various smaller fixes

built-in image buffering and re-sizing servlet. The result is shown much faster now not because YaCy does not need to re-size the images but
for a very strange other reason: because of RFC specification (http://tools.ietf.org/html/rfc2616#section-8.1.4) a browser does not open more than
two connections to the same server at the same time. If the YaCy image servlet is used, then the target host is the YaCy host for all images
and that prevents a parallel computation of the image loading.

- when a site-crawl for ftp sites is now started, then a special directory-tree harvester gets the complete directory structure of a ftp server at once
- the harvester runs concurrently and feeds into the normal crawl queue
also in this:
- fixed the 'start from file' crawl function
- added a link detector for the html parser. The html parser can now also extract links that are not included in <a> tags.
- this causes that a crawl start is now also possible from clear text link files

terminal_p.html: Put back the old ID which was really easy to find
IndexCreate.js: Because XHTML 1.0 Strict does not allow name tags for some elements rewrote most element access functions to use getElementById
Table_API_p.html and all other html pages: Some XHTMl 1.0 Strict fixes, changed checkAll javascript, marked the first row with checkboxes as unsortable where applicable
Table_API_p.java and all other java pages: URLencoded lines with possible ampersands & -> & for validation XHTML 1.0 Strict sourcecode
--> All Index Create pages should validate now. Hope I did not break anything else (too much :-)

- better crawl star for files paths and smb paths
- added time-out wrapper for dns resolving and reverse resolving to prevent blockings
- fixed intranet scanner result list check boxes
- prevented htcache usage in case of file and smb crawling (not necessary, documents are locally available)
- fixed rss feed loader
- fixes sitemap loader which had not been restricted to single files (crawl-depth must be zero)
- clearing of crawl result lists when a network switch was done
- higher maximum file size for crawler

- nobody understand the auto-dom filter without a lenghtly introduction about the function of a crawler
- nobody ever used the auto-dom filter other than with a crawl depth of 1
- the auto-dom filter was buggy since the filter did not survive a restart and then a search index contained waste
- the function of the auto-dom filter was in fact to just load a link list from the given start url and then start separate crawls for all these urls restricted by their domain
- the new Site Link-List option shows the target urls in real-time during input of the start url (like the robots check) and gives a transparent feed-back what it does before it can be used
- the new option also fits into the easy site-crawl start menu

ConfigPortal.html: Fixed some HTML problems to validate at least XHTML 1.0 Transitional - for strict the target attribute of the a link has to be removed
yacyinteractive.html: Moved all JS code to an external yacyinteractive.js file in JS folder
yacysearch.html: Removed embedded scripts from in between the body tags - now everything is loaded in the header
