Models for natural language processing use statistics to collect a wealth of information about word meanings.
In “Through the Looking Glass,” Humpty Dumpty says scornfully, “When I use a word, it means just what I choose it to mean — neither more nor less.” Alice replies, “The question is whether you can make words mean so many different things.”
Word meanings have long been the subject of research. To comprehend their meaning, the human mind must sort through a complex network of flexible, detailed information.
Now, a more recent issue with word meaning has come to light. Researchers are looking at whether machines with artificial intelligence would be able to mimic human thought processes and comprehend words similarly.
The study, which was published in the journal Nature Human Behaviour, demonstrates that artificial intelligence systems may really pick up on highly complex word meanings. The researchers also found a simple method for gaining access to this sophisticated information. They discovered that the AI system they looked at represents word meanings in a manner that closely resembles human judgment.
The AI system explored by the authors has been widely utilized to analyze word meaning throughout the last decade. It picks up word meanings by “reading” enormous quantities of material on the internet, which contains tens of billions of words.
When words frequently occur together — “table” and “chair,” for example — the system learns that their meanings are related. And if pairs of words occur together very rarely — like “table” and “planet,” — it learns that they have very different meanings.
That approach seems like a logical starting point, but consider how well humans would understand the world if the only way to understand meaning was to count how often words occur near each other, without any ability to interact with other people and our environment.
Idan Blank, a assistant professor of psychology and linguistics, and the study’s co-lead author, said the researchers set out to learn what the system knows about the words it learns, and what kind of “common sense” it has. Read More...
