ICSI-CRF: The Generation of References to the Main Subject and Named Entities Using Conditional Random Fields
نویسندگان
چکیده
In this paper, we describe our contribution to the Generation Challenge 2009 for the tasks of generating Referring Expressions to the Main Subject References (MSR) and Named Entities Generation (NEG). To generate the referring expressions, we employ the Conditional Random Fields (CRF) learning technique due to the fact that the selection of an expression depends on the selection of the previous references. CRFs fit very well to this task since they are designed for the labeling of sequences. For the MSR task, our system has a String Accuracy of 0.68 and a REG08Type Accuracy of 0.76 and for the NEG task a String Accuracy of 0.79 and REG08-Type Accuracy of 0.83.

Over the past decades, urban growth has been known as a worldwide phenomenon that includes widening process and expanding pattern. While the cities are changing rapidly, their quantitative analysis as well as decision making in urban planning can benefit from two-dimensional (2D) and three-dimensional (3D) digital models. The recent developments in imaging and non-imaging sensor technologies, s...
متن کاملA Novel Approach to Conditional Random Field-based Named Entity Recognition using Persian Specific Features
Named Entity Recognition is an information extraction technique that identifies name entities in a text. Three popular methods have been conventionally used namely: rule-based, machine-learning-based and hybrid of them to extract named entities from a text. Machine-learning-based methods have good performance in the Persian language if they are trained with good features. To get good performanc...

We describe our contribution to the Generation Challenge 2010 for the tasks of Named Entity Recognition and coreference detection (GREC-NER). To extract the NE and the referring expressions, we employ a combination of a Part of Speech Tagger and the Conditional Random Fields (CRF) learning technique. We finally experiment an original algorithm to detect co-references. We conclude with discussio...

In this paper, we present a domain focused Tamil Named Entity Recognizer for tourism domain. This method takes care of morphological inflections of named entities (NE). It handles nested tagging of named entities with a hierarchical tagset containing 106 tags. The tagset is designed with focus to tourism domain. We have experimented building Conditional Random Field (CRF) models by training the...
