In this, the second article of a series that explores semantic search technology, Peter Alesso will examine the main techniques currently employed to deveol semantic methods: He?ll focus in particular on the Semantic Web and on Latent Semantic Indexing (LSI). The article finishes wth a code sample that searches a document and highlights searched items; this code filters words using some basic LSI-based techniques in order to match concepts rather than words.
