Basset

Basset is a full-text PHP Information Retrieval library. This is a collection of developments in the field of IR and ported over to PHP for research purposes.

Basset provides different ways of searching through documents in a collection (ad-hoc retrieval), by applying advanced and experimental IR algorithms and/or techniques gathered from different Research studies and Conferences, most notably:

1. TREC
2. SIGIR
3. ECIR
4. ACM

Using the Cranfield Collection and the sample.php file

The Cranfield Collection has been the pioneer collection in information retrieval to validate a system's effectiveness.

I've included the 1400 abstract Cranfield Collection as an XML file that you can parse into separate files.

The test file at tests/sample.php can be executed right away to do the parsing and do a search for a single test query. Customize it to your needs if needed.

You can read Cranfield/cranfield-collection/cranqrel for Glassgow's qrels result.

I've also included SMART system's stopword list for standardization (see stopwords/stopwords.txt).
