Entity resolution (ER) is the problem of identifying and merging records that refer to the same real-world entity. In many scenarios, raw records are stored under heterogeneous environment. Specifically, the schemas of records may differ from each other. To leverage such records better, most existing work assume that schema matching and data exchange have been done to convert records under diff...

Entity Resolution (ER), the process of finding identical entities across different databases, is critical to many information integration applications. As sizes of databases explode in the big-data era, it becomes computationally expensive to recognize identical entities for all possible records with variations allowed. Profiling results show that approximate matching is the primary bottleneck....

Entity resolution (ER) is the task of identifying all records in a database that refer to the same underlying entity. This is an expensive task, and can take a significant amount of money and time; the end-user may want to take decisions during the process, rather than waiting for the task to be completed. We formalize an online version of the entity resolution task, and use an oracle which cor...

Unsupervised Models of Entity Reference Resolution

Entity resolution is the task of linking each mention of an entity in text to the corresponding record in a knowledge base (KB). Coherence models for entity resolution encourage all referring expressions in a document to resolve to entities that are related in the KB. We explore attentionlike mechanisms for coherence, where the evidence for each candidate is based on a small set of strong relat...

In many government applications we often find that information about entities, such as persons, are available in disparate data sources such as passports, driving licences, bank accounts, and income tax records. Similar scenarios are commonplace in large enterprises having multiple customer, supplier, or partner databases. Each data source maintains different aspects of an entity, and resolving...

The challenge of associating entities across multiple domains is a key problem in social media understanding. Successful cross-domain entity resolution provides integration of information from multiple sites to create a complete picture of user and community activities, characteristics, and trends. In this work, we examine the problem of entity resolution across Twitter and Instagram using gene...

Product entity resolution is an important part of online product search, where product entities coming from different websites need to be aggregated in the search results. In this paper, we propose an approach to product entity resolution using the descriptive power of an ontology. In our algorithm, we use similarity measures that are defined specifically for each type of product feature and le...

Motivated by the recent successful application of span-based models to entity-based information extraction tasks, we investigate for event coreference resolution, focusing on determining (1) whether successes entity can be extended coreference; (2) exploiting dependency between and related subtask trigger detection; (3) automatically computed benefit resolution. Empirical results standard evalu...

News archives present a vast base of cultural and social knowledge. However, their size is also the cause for difficult navigation through the sequence of articles, belonging to a certain topic thread. In the ideal scenario, one could navigate over the whole sequence of articles, where every article would link to other relevant articles, discussing the same event. Continuing progress in entity ...
