Conversational systems have recently attracted significant attention. Both the research community and industry believe that it will exert huge impact on human-computer interaction, and specifically, the IR/RecSys community has begun to explore Conversational Recommendation. In real-life scenarios, such systems are often urgently needed in helping users accomplishing different tasks under various situations. However, existing works still face several shortcomings: (1) Most efforts are largely confined in single task setting. They fall short of hands in handling tasks across domains. (2) Aside from soliciting user preference from dialogue history, a conversational recommender naturally has access to the back-end data structure which …

Defect localization aims to locate buggy program elements (e.g., buggy files, methods or lines of code) based on defect symptoms, e.g., bug reports or program spectrum. However, when we receive the defect symptoms, the defect has been exposed and negative impacts have been introduced. Thus, one challenging task is: whether we can locate buggy program prior to appearance of the defect symptom at an early time (e.g., when buggy program elements are being checked-in). We refer to this type of defect localization as “Just-In-Time (JIT) Defect localization”. Although many prior studies have proposed various JIT defect identification methods to identify …


Building A Long-Time Series For Weather And Extreme Weather In The Straits Settlements: A Multi-Disciplinary Approach To The Archives Of Societies, Fiona Williamson Apr 2021

Building A Long-Time Series For Weather And Extreme Weather In The Straits Settlements: A Multi-Disciplinary Approach To The Archives Of Societies, Fiona Williamson

Research Collection School of Social Sciences

In comparison to the Northern Hemisphere, especially Europe and North America, there is a scarcity of information regarding the historic weather and climate of Southeast Asia and the Southern Hemisphere in general. The reasons for this are both historic and political, yet that does not mean that such data do not exist. Much of the early instrumental weather records for Southeast Asia stem from the colonial period and, with some countries and regions changing hands between the European powers, surviving information tends to be scattered across the globe making its recovery a long and often arduous task. This paper focuses …


A Question Of Scale: Making Meteorological Knowledge And Nation In Imperial Asia, Fiona Williamson, Vladimir Jankovic Nov 2020

A Question Of Scale: Making Meteorological Knowledge And Nation In Imperial Asia, Fiona Williamson, Vladimir Jankovic

Research Collection School of Social Sciences

This special issue of History of Meteorology explores processes of making, communicating, and embedding modern meteorological knowledge in late nineteenth and early twentieth century imperial Asia. Its focus is on the institutionalisation of meteorology in key nation-building activities such as developing agricultural services, synoptic mapping to predict storms, and participation in scientific organisations and initiatives. Collectively, the essays explore the intersection of local, regional, and international scales and processes in generating new forms of state-sponsored meteorological practices and institutions, though complex multi-layered networks involving different actors and modes of information flow across multiple scales. In so doing, they reveal the …


The Science Of Stifling Heat: Recognising Urban Climate Change In The Straits Settlements, Fiona Williamson Jun 2020

The Science Of Stifling Heat: Recognising Urban Climate Change In The Straits Settlements, Fiona Williamson

Research Collection School of Social Sciences

Heat is a ubiquitous part of tropical living. During the nineteenth century consumers and writers of travel literature, explorers and colonists became increasingly familiar with the endless, languid summers of tropical climates where continued, unrelenting heat and humidity created a daunting climate for the European.
