Our brain encounters billions of objects or precepts on a daily basis. These data come in varying forms such as sound, smell and images (vision). Our sensory systems such as eyes, nose, ears, tongue and touch encode these signals that could either be transmitted to our brains or ignored. It is absolutely impossible to process all the signals our senses come in contact with on a daily basis. All of these signals are known as precepts and a few of these become concepts. Entities or signals that assume the role of concepts are those we can develop a relational identity. Example, you visit a sports store and see running shoes displayed in the far right corner, these are all precepts. When you relate or associate the shoes with running a 5k, 10k, half or full marathon, they now become a concept. It takes relational thinking and reasoning to transform precepts into concepts. But there are differences between relational thinking and reasoning.
Name entity recognition is usually viewed as a low level NLP task but could be crucial to other tasks such as named entity disambiguation and linking. It is also relevant for information retrieval and question and answering applications. Standard named entity recognition classes are usually person, location and miscellaneous. I used the AllenNLP demo application to run a quick NER test for the Hacksaw ridge storyline. The text was extracted from the IMDB website and the below image indicates the entities. Previous research led to the identification of three core classes – person, location and organisation. During the Computational Natural Language Learning conference of 2003, a miscellaneous type was then added to the mix
The below reveals the four main entity classes or the non-fine grained, All four (person, organisation, location and miscellaneous) entity tags are highlighted. Desmond T. Doss is the name of the star character in the story and it is accurately identifies him as a person. When his surname was mentioned (Doss’s), it also has the accurate personal tag. The miscellaneous tag was used for events like the ‘Battle of Okinawa’ and a thing ‘Congressional medal of honor.’
A blog and research paper from Google Deepmind brought our attention to the concept of relational reasoning. As humans we have the innate ability to connect the dots or plot a narrative from piece of information to make a decision either to run a search, make a purchase or predict the outcome of a movie. Artificial agents are yet to attain the creative human ability to connect entities together via a narrative exercise that leads to human action. A few days ago my wife told me an interesting story. She ran into a friend at the entrance of a shop, he’s just grabbed himself a drink and some popcorn. She asked him where he was headed and he said to West India Quay. It is a place in east London which boasts of a handful of restaurants, bars and a cinema. She pieced together the the popcorn, drinks and West Indian Quay and asked him if he was headed to the cinema? He was quite surprised and affirmed he was headed to the cinema. She then predicted or stated that he owns a monthly Cineworld membership. He was quite shocked and nodded to having a monthly Cineworld membership. She told me, her experience of buying popcorn, drink and preferring the West India Quay Cineworld with her Meetup movie mates, assisted her in creating a relationship and narrative from the little information she received to correctly predict the intention of her friend. This is relational reasoning at work as the deepmind team clearly mentioned “ We carve our world into relations between things. And we understand how the world works through our capacity to draw logical conclusions about how these different things – such as physical objects, sentences, or even abstract ideas – are related to one another.”
