Department Research Seminar: Early Detection of Research Topics

On the 8th February I delivered a seminar to my department (KMi @ OU) in which I described the work I have been doing in the last two years for my postgraduate research.

I started with a little bit of introduction about science. Shortly, I moved to the currently available technologies for keeping track of the development of the different research areas. I showed how this technologies were not satisfactory enough if we want to perform an early detection of research topics.

In presenting, the state of the art (including The Structure of Scientific Revolution by Kuhn), I could state my main hypothesis, regarding the existence of an embryonic stage that research areas face, and that it is possible to detect their emergence during this stage1.

Abstract:

The ontology engineering research community has focused for many years on supporting the creation, development and evolution of ontologies. Ontology forecasting, which aims at predicting semantic changes in an ontology, represents instead a new challenge. In this paper, we want to give a contribution to this novel endeavour by focusing on the task of forecasting semantic concepts in the research domain. Indeed, ontologies representing scientific disciplines contain only research topics that are already popular enough to be selected by human experts or automatic algorithms. They are thus unfit to support tasks which require the ability of describing and exploring the forefront of research, such as trend detection and horizon scanning. We address this issue by introducing the Semantic Innovation Forecast (SIF) model, which predicts new concepts of an ontology at time t + 1, using only data available at time t. Our approach relies on lexical innovation and adoption information extracted from historical data. We evaluated the SIF model on a very large dataset consisting of over one million scientific papers belonging to the Computer Science domain: the outcomes show that the proposed approach offers a competitive boost in mean average precision-at-ten compared to the baselines when forecasting over 5 years.

Advances Towards Early Detection of Research Topics

Acknowledging new trends in the research environment is important for many stakeholders, such as researchers, institutional funding bodies, academic publishers, and companies. In particular, being able to identify them as soon as possible can bring an important strategical advantage.

A trend is usually defined as the general direction in which something is evolving. It is often used to describe the popularity of items, such as brands, words, and technologies. In order to detect trends, the relevant items should usually be already recognized and often somewhat popular. For this reason, current methods for detecting trends of research topics usually focus on identifying terms associated with a substantial number of documents, which usually took some years to be produced. Conversely, I theorise that it is possible to perform very early detection of research trends by identify embryonic topics, which have not yet been explicitly labelled or identified by a research community, and that is possible to do so by analysing the dynamics of existent topics. My work is grounded in Kuhn’s theory [1] of the scientific revolution according to which a paradigm shift, also called scientific revolution occurs when a paradigm cannot cope with anomalies, leading to a crisis that will persist until a new outcome redirects research through a new paradigm. In this abstract, I will discuss the state of the art, present an initial study which supports my hypothesis and outline the future directions of my work.
