Semantic relationships

Information on searching for semantic relationships

Introduction

This application searches for semantic relationships in a text by analysing the statistical properties of words.

It is not based on rules but on the probability that two words can appear in the same phrase without having a relationship.

Technology

It creates an n-dimensional representation of words (PLSA) by using the statistical properties of the words which appear next to them as coordinates. This demo uses European Parliament debates as its corpus.

Why have we developed this?

This technology is an integral part of a more complicated project able to extract translated terminology from the web.

For example, if you want to find on the web the English translation of ‘Metallizzazione’, it will be difficult to find bilingual sites from where the information can be extracted. But you will find on google more than 50.000 Italian pages which talk about "Metallizzazione". From these pages, you will discover that ‘Metallazzione’ has semantic relationships with "vuoto", "impianto", "vernice", "finitura", "metallo" for which the English translations can be easily found. At this point, you can search for what the words "vacuum", "plant", "paint", "metal" have in common and the answer will be "Metallization", the translation you were looking for!.
