A language modeling approach to entity recognition and disambiguation for search queries

Bhavana Dalvi, Chenyan Xiong, Jamie Callan
2014 Proceedings of the first international workshop on Entity recognition & disambiguation - ERD '14  
The Entity Recognition and Disambiguation (ERD) problem refers to the task of recognizing mentions of entities in a given query string, disambiguating them, and mapping them to entities in a given Knowledge  ...  Second, we retrieve candidate entities by searching for these candidate entity strings in Freebase. Third, we rank the candidate entities using language model based query likelihood scores.  ...  CONCLUSIONS We described a four step algorithm called Topic-specific Language Model (TLM method) for doing Entity Recognition and Disambiguation from search queries.  ...

Query Segmentation and Resource Disambiguation Leveraging Background Knowledge

Saeedeh Shekarpour, Axel-Cyrille Ngonga Ngomo, Sören Auer
2012 International Semantic Web Conference  
In this paper we introduce a novel approach for determining the correct resources for user-supplied keyword queries based on a hidden Markov model.  ...  While linguistic methods like named entity, multi-word unit recognition and POS-tagging fail in the case of an incomplete sentences (e.g. for keyword-based queries), we will show that our statistical approach  ...  First we introduce the concept of hidden Markov models and then we detail how we define the parameters of a hidden Markov model for solving the query segmentation and entity disambiguation problem.  ...

Named Entity Disambiguation for German News Articles

Andreas Lommatzsch, Danuta Ploch, Ernesto William De Luca, Sahin Albayrak
2010 Lernen, Wissen, Daten, Analysen  
Named entity disambiguation has become an important research area providing the basis for improving search engine precision and for enabling semantic search.  ...  Based on a German and an English document corpus, we evaluate various similarity measures and algorithms for extracting data for named entity disambiguation.  ...  The corpus contains a set of queries where each query consists of a query string, and a set of approximately 200 documents (retrieved from a search engine for the query string).  ...

Hierarchical classification for Multilingual Language Identification and Named Entity Recognition

Saatvik Shah, Vaibhav Jain, Sarthak Jain, Anshul Mittal, Jatin Verma, Shubham Tripathi, Rajesh Kumar
2015 Forum for Information Retrieval Evaluation  
The detected named entities are further subclassified by a novel unsupervised technique based on query refinement and keyword based scoring.  ...  The subtask involved multilingual language identification (including mixed words and anomalous foreign words), named entity recognition (NER) and subclassification.  ...  This research paper addresses language identification (LI) and Named Entity Recognition (NER) for text in social media.  ...

However, NEs can have different spellings for each language which reduces the performance of user queries to retrieve documents across languages.  ...  We tested this approach to analyze documents and NEs in low-resourced languages and link them to the English version of Wikipedia.  ...  ACKNOWLEDGMENTS This work has been partly supported by the European Union's Horizon 2020 research and innovation programme under grants 770299 (NewsEye) and 825153 (EMBEDDIA).  ...

Entity Linking in Queries: Efficiency vs. Effectiveness [chapter]

Faegheh Hasibi, Krisztian Balog, Svein Erik Bratsberg
2017 Lecture Notes in Computer Science  
Identifying and disambiguating entity references in queries is one of the core enabling components for semantic search.  ...  Our goal is to gain a deeper understanding of how to approach entity linking in queries, with a special focus on how to strike a balance between effectiveness and efficiency.  ...  Our experiments have led to two important findings: (i) it is more rewarding to employ supervised learning for candidate entity ranking than for disambiguation, and (ii) entity interdependence features  ...
