ht://Miner version 0.5.0 (beta) released

The Comune di Prato and the ht://Miner Group are very proud to announce
that a new release of the ht://Miner Web Usage Mining system is
available for download.

ht://Miner is an advanced system for Web usage mining and data
warehouse: it allows the discovery of knowledge from data (KDD)
regarding users' usage on the Web (such as unique visitors, sessions,
transactions) and organise it in a PostgreSQL database. It is written in
C++.

ht://Miner can be downloaded from the sourceforge.net website
(http://sourceforge.net/projects/htminer/).

Release 0.5.0 is another important step towards stability. Several bugs
have been fixed and new features have been introduced at all the
different levels of the web usage mining process.

A key point, crucial for middle size organisations, is the introduction
of a multi-level summarisation framework in the custom data warehouse
(currently just for the only subject that is implemented: anonymous
requests of pages grouped by day). This architecture allows the use of a
summary navigation system that is typical of data warehouses, with
different level of data aggregation. The PHP middleware takes advantage
of this structure, with online improvements of queries by 1000 times (in
the most complicated scenarios).

Support for PostgreSQL 8.2.x has been added.

Another key aspect is that release 0.5.0 is the first release that has
been officially adopted by the Comune di Prato for web usage statistics
production and data warehousing.

Although it cannot still be considered stable (for the presence of a bug
regarding concurrency in the OLTP processing module - which needs some
refactoring), this version is the best available so far and its usage
for production is recommended.

For more details on this version, please refer to the release notes
(http://sourceforge.net/project/shownotes.php?group_id=131432&release_id=483350
<http://sourceforge.net/project/shownotes.php?group_id=131432&release_id=483350>).

Please feel free to ask for help in case you need assistance with
compilation, installation and configuration issues. You can also
subscribe the htminer-help mailing list from the SourceForge.net panel.

Thank you very much.
