Interactions of food proteins with plant phenolics – modulation of structural, techno- and bio-functional properties of proteins
… The phenolic compounds, e.g. chlorogenic acid (CQA), are susceptible to oxidation by enzymes specially, polyphenol oxidase (PPO) and at alkaline conditions. Both enzymatic and non-enzymatic oxidations occur in the presence of oxygen and produce quinone, which normally further react with other …

Automated Approaches to Community Question Answering
… search. Thus, Community Question Answering (cQA), a branch of QA, has been developed with the aim of automatically answering new user questions. Generally, cQA systems answer new user questions by (i) first looking at the questions most similar to the input question and (ii) selecting the …

Using Gaze Tracking to Tackle Duplicate Questions on Community Based Question Answering Websites: A Case Study of Ifixit
… questions on Community based Question Answering (CQA) websites has increased significantly due to the rising number of duplicate questions. This is a serious problem, one that could lead to the decline of such beneficial websites.</p> <p>This thesis presents novel avenues that use gaze tracking …

Containment of Organic Contaminants Using Geosynthetics
… (MSW) with good construction quality assurance (CQA), PCBs are unlikely to give rise to environmental concern. However, if CQA allows significant leakage, the environmental impacts from PCBs would need to be carefully evaluated on a case by case basis by modelling. Containment using geosynthetics …

Autonomous agents for serving complex information needs
… questions on community question answering (cQA) websites. This task required more detailed semantic information in the form of a database containing precise medical entities, verbose text descriptions, and the relations between them. These were obtained by using health information websites …

Towards high quality, scalable education: Techniques in automated assessment and probabilistic user behavior modeling
… roles in community question answering (CQA) platforms using a generative model called the MDMM behavior model. I show interesting distinctions within CQA communities in question-asking behavior (where two distinct types of askers can be identified) and answering behavior (where two …

Community Question Answering : an Investigation into the Influence of Question Expansion based on User's Explicit Information on Learning to Rank Q&A Models
… (LTR) models for Community Question Answering (CQA) require additional explicit information to appropriately expand questions, enabling the identification of an accurate ranked list of answer candidates based on their relevance to the question. This doctoral thesis proposes an investigation into …

Using an In Vitro-In Vivo Correlation for the ‘Bioequivalence by Design’ Development of an Immediate Release Carbamazepine Product
… identification of critical quality attributes (CQA) which summarize a product’s performance, the efficient refinement of critical product/process parameters (CPP) that can affect such attributes, and the systematic development of CPP limits, which assure appropriate performance of CQAs. For a …
