Beyond Optimizing for Clicks: Incorporating Editorial Values in News Recommendation
Feng Lu, Anca Dumitrache, David Graus
With the uptake of algorithmic personalization in the news domain, news organizations increasingly trust automated systems with previously considered editorial responsibilities, e.…
A Crowdsourced Frame Disambiguation Corpus with Ambiguity
Anca Dumitrache, Lora Aroyo, Chris Welty
We present a resource for the task of FrameNet semantic frame disambiguation of over 5,000 word-sentence pairs from the Wikipedia corpus. The annotations were collected using a nov…
Empirical Methodology for Crowdsourcing Ground Truth
Anca Dumitrache, Oana Inel, Benjamin Timmermans +4
The process of gathering ground truth data through human annotation is a major bottleneck in the use of information extraction methods for populating the Semantic Web. Crowdsourcin…
Crowdsourcing Semantic Label Propagation in Relation Classification
Anca Dumitrache, Lora Aroyo, Chris Welty
Distant supervision is a popular method for performing relation extraction from text that is known to produce noisy labels. Most progress in relation extraction and classification…
CrowdTruth 2.0: Quality Metrics for Crowdsourcing with Disagreement
Anca Dumitrache, Oana Inel, Lora Aroyo +2
Typically crowdsourcing-based approaches to gather annotated data use inter-annotator agreement as a measure of quality. However, in many domains, there is ambiguity in the data, a…
Capturing Ambiguity in Crowdsourcing Frame Disambiguation
Anca Dumitrache, Lora Aroyo, Chris Welty
FrameNet is a computational linguistics resource composed of semantic frames, high-level concepts that represent the meanings of words. In this paper, we present an approach to gat…
False Positive and Cross-relation Signals in Distant Supervision Data
Anca Dumitrache, Lora Aroyo, Chris Welty
Distant supervision (DS) is a well-established method for relation extraction from text, based on the assumption that when a knowledge-base contains a relation between a term pair,…
Crowdsourcing Ground Truth for Medical Relation Extraction
Anca Dumitrache, Lora Aroyo, Chris Welty
Cognitive computing systems require human labeled data for evaluation, and often for training. The standard practice used in gathering this data minimizes disagreement between anno…
