Context Trees: Augmenting Geospatial Trajectories with Context

Exposing latent knowledge in geospatial trajectories has the potential to provide a greater level of understanding of individuals and groups than previously afforded. Motivated by a desire to understand the movement patterns of users, this work explores the potential offered by trajectories augmented with land usage information to understand the context behind user actions. The resultant context tree, a hierarchical data structure generated through novel filtering and clustering techniques, summarises historic contexts of the user in a manner that entails rapid access to information previously latent within the original trajectories. Context trees, combined with a technique for pruning that aims to reduce complexity with minimal loss of information, provide a foundation for understanding and modelling the behaviours of individuals and groups. The filtering, clustering and pruning stages of the proposed process, along with context trees generated from real-world data, are evaluated relative to desirable properties to demonstrate their utility.

Re-finding Behaviour in Vertical Domains

We differentiate and model user re-finding behavior within different media and topic domains that are related to the domains of vertical search engines (e.g. images, news, reference material, and movies). We distinguish the re-finding behavior from general search, and engineer features that are effective in differentiating re-finding across the domains. The features are then used to build machine learned models. While the accuracy of detection is 85.7%, compared with 97.5% when examining re-finding from general search tasks, to the best of our knowledge such an examination of vertical re-finding has not been tried before. We attempt to differentiate re-finding behavior when the history of a searchers interactions are not available. In this scenario we achieve an average accuracy of 77.5% across the domains. We also examine early detection of re-finding during a searchers session. Finally, we investigate in which types of domains is re-finding most difficult. Here, it would appear that re-finding images is particularly challenging for users. This research has implications for search engine design, in terms of adapting search results by predicting the type of user tasks and enabling the presentation of vertical-specific results when re-finding is identified.

Hilbert Exclusion: Improved Metric Search through Finite Isometric Embeddings

Most research into similarity search in metric spaces relies upon the triangle inequality property. This property allows the space to be arranged according to relative distances to avoid searching some subspaces. We show that many common metric spaces, notably including those using Euclidean and Jensen-Shannon distances, also have a stronger property, sometimes called the four-point property: in essence, these spaces allow an isometric embedding of any four points in three-dimensional Euclidean space, as well as any three points in two-dimensional Euclidean space. In fact, we show that any space which is isometrically embeddable in Hilbert space has the stronger property. This property gives stronger geometric guarantees, and one in particular, which we name the Hilbert Exclusion property, allows any indexing mechanism which uses hyperplane partitioning to perform better. One outcome of this observation is that a number of state-of-the-art indexing mechanisms over high dimensional spaces can be easily extended to give a significant increase in performance; furthermore, the improvement given is greater in higher dimensions. This therefore leads to a significant improvement in the cost of metric search in these spaces.

Cost-effective Online Trending Topic Detection and Popularity Prediction in Microblogging

Identifying topic trends on microblogging services such as Twitter and estimating those topics' future popularity have great academic and business value, especially when the operations can be done in real time. For any third party, however, retrieving and processing such huge volumes of real-time data in microblogs are almost infeasible tasks, as there always exist API request limits, monitoring and computing budgets, as well as timeliness requirements. To deal with these challenges, we propose a cost-effective system framework with algorithms that can automatically select an optimal subset of users in microblogging networks, under cost constraints. Then the proposed system can monitor and utilize only these selected users' real-time microposts to detect the overall trending topics and predict their future popularity among the whole microblogging network. Therefore, our proposed system framework is practical for real-time usage as it avoids retrieving and processing full real-time data, while not compromising detection and prediction performance under given cost constraints. Experiments with real microblogs dataset show that by tracking only 800 users out of 0.7 million users and processing no more than 30,000 microposts daily, about 75% trending topics could be detected and predicted by the proposed system, and on average 4.6 hours earlier than they appear in official trends list.

Fast Ranking with Additive Ensembles of Oblivious and Non-Oblivious Regression Trees

Learning-to-Rank models based on additive ensembles of regression trees have been proven to be very effective for scoring query results returned by large-scale Web search engines. Unfortunately, the computational cost of scoring thousands of candidate documents by traversing large ensembles of trees is high. Thus, several works have investigated solutions aimed at improving the efficiency of document scoring by exploiting advanced features of modern CPUs and memory hierarchies. In this paper, we present QuickScorer, a new algorithm that adopts a novel cache-efficient representation of a given tree ensemble, it performs an interleaved traversal by means of fast bitwise operations, and also supports ensembles of oblivious trees. An extensive and detailed test assessment is conducted on two standard learning-to-rank datasets and on a novel very-large dataset we made publicly available for conducting significant efficiency tests. The experiments show unprecedented speedups over the best state-of-the-art baselines ranging from 1.9x to 6.6x. The analysis of low-level profiling traces shows that QuickScorer efficiency is due to its cache-aware approach both in terms of data layout and access patterns, and to a control flow that entails very low branch mis-prediction rates.

Time-Aware Click Model

Click-through information is considered as a valuable source of users implicit relevance feedback for commercial search engines. As existing studies have shown that search result position in search engine result page(SERP) has a very strong influence on users examination behavior, most existing click models are position-based, assuming that users examine results from top to bottom in a linear fashion. While these click models have been successful, most do not take temporal information into account. As many existing studies have shown, click dwell time and click sequence information are strongly correlated with users perceived relevance and search satisfaction. In this paper, we investigate the problem of properly incorporating temporal information into click models. We firstly carry out a laboratory eye-tracking study to analyze users examination behavior in different click sequences. Afterwards, we analyze dwell time distribution in different search logs and find that we cannot simply use a click dwell time threshold to distinguish relevant/irrelevant results. Finally, we propose a novel click model named Time-Aware Click Model (TACM) that captures the temporal information of user behavior. Experimental results on practical search logs show that TACM outperforms other models in terms of both predicting click behavior (perplexity) and estimating result relevance (NDCG).

Learning Informative Priors from Heterogeneous Domains to Improve Recommendation in Cold-Start User Domains

Users often have sufficient experience in their focused domains but lack experience in others. Recommender systems are helpful for recommending potentially desirable items to users in unfamiliar domains, and cross-domain collaborative filtering is therefore an important emerging research topic. However, it is inevitable that the cold-start issue will be encountered in unfamiliar domains due to the lack of feedback data. The Bayesian approach shows that priors play an important role when there are insufficient data, which implies that recommendation performance can be significantly improved in cold-start domains if informative priors can be provided. Based on this idea, we propose a Weighted Irregular Tensor Factorization (WITF) model to leverage multi-domain feedback data to learn the cross-domain priors w.r.t. both users and items. The features learned from WITF serve as the informative priors on the latent factors of users and items in terms of weighted matrix factorization models. Moreover, WITF is a unified framework for dealing with both explicit feedback and implicit feedback. To prove the effectiveness of our approach, we studied three typical real-world cases in which a collection of empirical evaluations were conducted on real-world datasets to compare the performance of our model and other state-of-the-art approaches. The results show the superiority of our model over comparable models.

On Crowdsourcing Relevance Magnitudes for Information Retrieval Evaluation

Magnitude estimation is a psychophysical scaling technique for the measurement of sensation, where observers assign numbers to stimuli in response to their perceived intensity. We investigate the use of magnitude estimation for judging the relevance of documents for information retrieval evaluation, carrying out a large-scale user study across 18 TREC topics and collecting over 50,000 magnitude estimation judgments using crowd sourcing. Our analysis shows that, on average, magnitude estimation judgments are rank-aligned with ordinal judgments made by expert relevance assessors. We explore the application of magnitude estimation for IR evaluation, calibrating two gain-based effectiveness metrics, nDCG and ERR, directly from user-reported perceptions of relevance. A comparison of TREC system effectiveness rankings based on binary, ordinal, and magnitude estimation relevance shows substantial variation; in particular, the top systems ranked using magnitude estimation and ordinal judgments differ substantially. Analysis of the magnitude estimation scores shows that this effect is due in part to varying perceptions of relevance: different users have different perceptions of the impact of relative differences in document relevance. These results have direct implications for IR evaluation, suggesting that current assumptions about a single view of relevance being sufficient to represent a population of users are unlikely to hold.

Boosting Recommendation in Unexplored Categories by User Price Preference

State-of-the-art methods for product recommendation encounter significant performance drop in categories where a user has no purchase history. This problem needs to be addressed since current online retailers are moving beyond single category and attempting to be diversified. In this paper, we investigate the challenging problem of product recommendation in unexplored categories and discover that the price, a factor comparable across categories, can improve the recommendation performance significantly. We introduce the price utility concept to characterize users' sense of price and propose three different utility functions. We show that user price preference in a category is a distribution and we mine typical user price preference patterns based on three different types of distance between distributions. We fuse user price preference through regularization and joint factorization to boost recommendation performance in both browsing and buying shopping orientations. Experimental results show that fusing user price preference improves performance in a series of recommendation tasks: unexplored category recommendation, product recommendation under a given unexplored category and product recommendation under generic unexplored categories.
