Rod Page 's demo for his Elsevier Grand Challenge submission (" Towards realising Darwin’s dream: setting the trees free ") shows the type of enrichment of biological - if not all research - articles that is quickly becoming possible. Taking a published article (" Mitochondrial paraphyly in a polymorphic poison frog species (Dendrobatidae; D. pumilio "), various additional biological, geographical and other metadata are extracted and added to a web page for the article. These include: Map showing all localities mentioned in the paper, with their enclosing polygon List of other studies which have samples in area enclosed by the study polygon Each of the following are linked through to their underlying databases (such as NIH accession number and NCBI nucleotide viewer or linked to ubio taxonomic name viewer record: List of sequence features (such as genes) in the article List of taxa sequenced in the article List of gene sequences cited by the article An image c...

I have been doing some indexing performance tests with LuSql , and have some numbers comparing Lucene 2.3.1 with 2.4. Despite some discussion about 2.4 having poorer indexing performance, my tests with LuSql 0.9 suggest otherwise: Lucene 2.3.1 Number of records added= 2000000 Optimizing index Closing index Optimizing index time: 311 seconds Closing JDBC: result set Closing JDBC: statement Closing JDBC: connection *********** Elapsed time: 854 seconds 15m 18s Lucene 2.4 Number of records added= 2000000 Optimizing index Closing index Optimizing index time: 322 seconds Closing JDBC: result set Closing JDBC: statement Closing JDBC: connection *********** Elapsed time: 759 seconds 12m 39s Index size: 3.7GB. It is interesting that the overall indexing time is significantly less, but the optimizing time is slightly higher. Data, hardware and system configuration: as per my previous Lucene benchmarking . Note that this is a simple benchmark, so YMWV. This benchmark was done with the LuSql de...

LuSql is a simple but powerful tool for building Lucene indexes from relational databases. It is a command-line Java application for the construction of a Lucene index from an arbitrary SQL query of a JDBC -accessible SQL database. It allows a user to control a number of parameters, including the SQL query to use, individual indexing/storage/term-vector nature of fields, analyzer, stop word list, and other tuning parameters. In its default mode it uses threading to take advantage of multiple cores. LuSql can handle complex queries, allows for additional per record sub-queries, and has a plug-in architecture for arbitrary Lucene document manipulation. Its only dependencies are three Apache Commons libraries, the Lucene core itself, and a JDBC driver. LuSql has been extensively tested, including a large 6+ million full-text & article metadata document collection, producing an 86GB Lucene index. I am the author of the LuSql software.

In the 25th anniversary issue (November/December 2008 (vol. 25 no. 6)) of IEEE Software , my NRC colleague Anatol Kark is part of the editorial team for the special issue on " Opportunistic Software Systems Development ". These are all great articles, and I particularly like the Jansen et al article (" Pragmatic and Opportunistic Reuse in Innovative Start-up Companies ") and feel that almost everyone who is trying to bring their organizationl IT into the 21st century should be forced to read the Gamble et al article (" Monoliths to Mashups: Increasing Opportunistic Assets ").
