[jira] Updated: (NUTCH-439) Top Level Domains Indexing / Scoring
[ https://issues.apache.org/jira/browse/NUTCH-439?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Enis Soztutar updated NUTCH-439: Attachment: tld_plugin_v1.0.patch This is a plugin implementation for indexing and scoring top level domains in nutch. Tlds are stored in TLDEntry class, which has fields domain, status and boost fileds. The tlds are read from an xml file. There is also a xsd for validation. TLDIndexingFilter implements IndexingFilter interface to index the domain extensions (such as "net", "org", "en", "de") in the tld field. TLDScoringFilter implements ScoringFilter interface. Basically this filter multiplies the initial boost(coming from another scoring filter such as opic) by the boost of the domain. This way, by configuring boost of say "edu" domains to 1.1, the document boosts in the index of educational sites is boosted by 1.1. Also local search engines may wish to boost the domains hosted in that country. For ex. boosting "de" domains a little in a German SE seems reasonable. An alternative usage may be to lower the boosts of domains such as biz, or info, which are known to have lots of spam. The users can also query the tld field for advanced search. Implementation note : 1. OpicScoringFilter is changed to respect ScoringFilter chaining. 2. some of the second level domains such as co.uk is not recognized, but edu.uk is recognized > Top Level Domains Indexing / Scoring > > > Key: NUTCH-439 > URL: https://issues.apache.org/jira/browse/NUTCH-439 > Project: Nutch > Issue Type: New Feature > Components: indexer >Affects Versions: 0.9.0 >Reporter: Enis Soztutar > Attachments: tld_plugin_v1.0.patch > > > Top Level Domains (tlds) are the last part(s) of the host name in a DNS > system.

[ https://issues.apache.org/jira/browse/NUTCH-439?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Enis Soztutar updated NUTCH-439: Attachment: tld_plugin_v2.0.patch I have made major improvements to the code and configuration files. Mainly the issue is not only a plugin, but a package, one big xml file, and an indexing/scoring plugin(which is disabled by default). The list of recognized suffixes now is not limited to top level domains. second, or third level public domain names can be recognized. The patch also changes the naming from top level domains to domain suffixes. This patch also introduces URLUtil class, which include methods for getting domain name, or public domain suffix of an url. Finding the domain name of a url is quite important for several reasons. First we can use this function as an replacement of URL.getHost() in LinkDB for ignoring internal links, or in similar context. Second we can perform statistical analysis on domain names. Third we can list subdomains under a domain, etc.. I have changed the build.encoding to UTF-8 so that non-ascii characters are recognized. here is an excerpt from the domain-suffixes.xml file : This document contains top level domains as described by the Internet Assigned Numbers Authotiry (IANA), and second or third level domains that are known to be managed by domain registerers. People at Mozilla community call these as public suffixes or effective tlds. There is no algorithmic way of knowing whether a suffix is a public domain suffix, or not. So this large file is used for this purpose. The entries in the file is used to find the domain of a url, which may not the same thing as the host of the url. For example for "http://lucene.apache.org/nutch"; the hostname is lucene.apache.org, however the domain name for this url would be apache.org. Domain names can be quite handy for statistical analysis, and fighting against spam. The list of TLDs is constructed from IANA, and the list of "effective tlds" are constructed from Wikipedia, http://wiki.mozilla.org/TLD_List, and http://publicsuffix.org/ The list may not include all the suffixes, but some effort has been spent to make it comprehensive. Please forward any improvements for this list to nutch-dev mailing list, or nutch JIRA. > Top Level Domains Indexing / Scoring > > > Key: NUTCH-439 > URL: https://issues.apache.org/jira/browse/NUTCH-439 > Project: Nutch > Issue Type: New Feature > Components: indexer >Affects Versions: 0.9.0 >Reporter: Enis Soztutar > Attachments: tld_plugin_v1.0.patch, tld_plugin_v1.1.patch, > tld_plugin_v2.0.patch > > > Top Level Domains (tlds) are the last part(s) of the host name in a DNS > system.

Thanks !

DomainStatistics is really a quick hack i've written for demonstration of the
new patch. I've moved it from the latest patch. Once the user requirements are
settled, we can move on from there.
Also you may not want to commit MozillaPublicSuffixListParser.java, but it is
good we have it somewhere public.

[ https://issues.apache.org/jira/browse/NUTCH-439?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Enis Soztutar updated NUTCH-439: Attachment: tld_plugin_v2.3.patch bq. TLDScoringFilter contains a misspelled field, tldEnties, it should be renamed to tldEntries Done! bq. one of the use cases for the "tld" index field that you mention is that users may search on it. But in the latest patch this field is added with Field.Index.NO, which makes searching on it impossible. Also, in order to search on arbitrary Lucene fields Nutch needs a Query filter, so we would need a TLDQueryFilter, which doesn't exist (yet?). Well, infact NUTCH-445 covers searching on tlds, namely we would be able to search site:lucene.apache.org, or site:apache.org or even site:org, therefore i think indexing tld fields and TLDQueryFilter is not needed. I will delve deeper into NUTCH-445 as soon as i find some time. We can move domain indexing functionality to index-basic so that it will be generic enough. bq. using domain names instead of host names - we need to discuss this further, let's create a separate issue on this. we can open issues case by case since the patches is expected to have major side effects. > Top Level Domains Indexing / Scoring > > > Key: NUTCH-439 > URL: https://issues.apache.org/jira/browse/NUTCH-439 > Project: Nutch > Issue Type: New Feature > Components: indexer >Affects Versions: 0.9.0 >Reporter: Enis Soztutar >Assignee: Enis Soztutar > Attachments: tld_plugin_v1.0.patch, tld_plugin_v1.1.patch, > tld_plugin_v2.0.patch, tld_plugin_v2.1.patch, tld_plugin_v2.2.patch, > tld_plugin_v2.3.patch > > > Top Level Domains (tlds) are the last part(s) of the host name in a DNS > system.
