Consumption of antimicrobial drugs, such as antibiotics, is linked with antimicrobial resistance. Surveillance of antimicrobial drug consumption is therefore an important element in dealing with antimicrobial resistance. Many countries lack sufficient surveillance systems. Usage of web mined data therefore has the potential to improve current surveillance methods. To this end, ...

We investigate the utility of multi-task learning to disease surveillance using Web search data. Our motivation is two-fold. Firstly, we assess whether concurrently training models for various geographies - inside a country or across different countries - can improve accuracy. We also test the ability of such models to assist ...

Influenza-like illness (ILI) estimation from web search data is an important web analytics task. The basic idea is to use the frequencies of queries in web search logs that are correlated with past ILI activity as features when estimating current ILI activity. It has been noted that since influenza is ...

Health surveillance systems based on online user-generated content often rely on the identification of textual markers that are related to a target disease. Given the high volume of available data, these systems benefit from an automatic feature selection process. This is accomplished either by applying statistical learning techniques, which do ...

Estimating vaccination uptake is an integral part of ensuring public health. It was recently shown that vaccination uptake can be estimated automatically from web data, instead of slowly collected clinical records or population surveys. All prior work in this area assumes that features of vaccination uptake collected from the web ...

We propose an extension to language models for information retrieval. Typically, language models estimate the probability of a document generating the query, where the query is considered as a set of independent search terms. We extend this approach by considering the concepts implied by both the query and words in ...

Online ranker evaluation focuses on the challenge of efficiently determining, from implicit user feedback, which ranker out of a finite set of rankers is the best. It can be modeled by dueling bandits , a mathematical model for online learning under limited feedback from pairwise comparisons. Comparisons of pairs of ...

Online ranker evaluation is a key challenge in information retrieval. An important task in the online evaluation of rankers is using implicit user feedback for inferring preferences between rankers. Interleaving methods have been found to be efficient and sensitive, i.e. they can quickly detect even small differences in quality. It ...

This paper investigates whether infectious intestinal diseases (IIDs) can be detected and quantified using social media content. Experiments are conducted on user-generated data from the microblogging service, Twitter. Evaluation is based on the comparison with the number of IID cases reported by traditional health surveillance methods. We employ a deep ...

In sponsored search, advertisement (abbreviated ad) slots are usually sold by a search engine to an advertiser through an auction mechanism in which advertisers bid on keywords. In theory, auction mechanisms have many desirable economic properties. However, keyword auctions have a number of limitations including: the uncertainty in payment prices ...

Assessing the effect of a health-oriented intervention by traditional epidemiological methods is commonly based only on population segments that use healthcare services. Here we introduce a complementary framework for evaluating the impact of a targeted intervention, such as a vaccination campaign against an infectious disease, through a statistical analysis of ...

A common problem in unstructured peer-to-peer (P2P) information retrieval is the need to compute global statistics of the full collection, when only a small subset of the collection is visible to a peer. Without accurate estimates of these statistics, the effectiveness of modern retrieval models can be reduced. We show ...

We investigate the problem of identifying trending information in a peer-to-peer micro-blogging online social network. In a distributed decentralized environment, the participating nodes do not have access to global statistics such as the frequencies of the keywords and the information creation rate. We propose a two step solution. First, nodes ...

The recent rise in the popularity of micro-blogging has been accompanied by concerns over censorship and anonymity in centralized systems. Thus, we consider the problem of implementing a micro-blogging social network over an unstructured Peer-to-Peer network. The problem can be decomposed into two sub-problems, dissemination (also known as replication) and ...

Non-uniformly distributing documents in an unstructured peer-to-peer (P2P) network has been shown to improve both the expected search length and search accuracy, where accuracy is defined as the size of the intersection of the documents retrieved by a constrained, probabilistic search and the documents that would have been retrieved by ...

We propose a mathematical framework for query selection as a mechanism for reducing the cost of constructing information retrieval test collections. In particular, our mathematical formulation explicitly models the uncertainty in the retrieval effectiveness metrics that is introduced by the absence of relevance judgments. Since the optimization problem is computationally ...

We describe a framework for a micro-blogging social network implemented in an unstructured peer-to-peer network. A micro-blogging social network must provide capabilities for users to (i) publish, (ii) follow and (iii) search. Our retrieval mechanism is based on a probably approximately correct (PAC) search architecture in which a query is ...
